Thanks, Shawn. Good afternoon, everyone, and thank you for joining us for our Q4 2021 earnings call. We are pleased to report another strong quarter. We entered our first year as a public company on a high note, delivering 77% revenue growth and 121% gross profit growth year-over-year in Q4. We are rapidly delivering on our mission to build a leading global digital manufacturing marketplace, transforming one of the largest industries in the world. While we're still in the early innings of this secular shift to digital manufacturing, Fortune 1000 companies are increasingly rethinking their supply chains and manufacturing strategies. Xometry is uniquely positioned to meet their needs through the breadth of our platform across verticals, processes and capabilities. Likewise, we are uniquely positioned to meet the needs of our sellers through our suite of seller services. With our cloud-based software platform, we aim to be the operating system for hundreds of thousands of sellers. Global events over the last two years have crippled supply chains, spurred product shortages and limited access to raw materials, underscoring the need for rapid digital transformation of the manufacturing industry. Our two-sided marketplace has performed exceptionally well through the manufacturing volatility of the past two years, including COVID, ongoing supply chain disruptions and the current tragedy in Ukraine. Our ability to match buyers and suppliers in real-time and our weekly updates to our AI-driven pricing model provide reliable pricing and predictable margins even during periods of volatile commodity prices. Likewise, with our supplier network expanding domestically and abroad, we offer our customers durable supply chains irrespective of macro events. The vast majority of our orders are fulfilled in-country alleviating issues related to overseas shipping delays, and the addition of Thomas only enhances our capabilities. While our thoughts go out to those tragically affected by the war in Ukraine, Xometry continues to have strong and growing business in Europe. We do not have buyers or sellers in Ukraine or Russia, and have not experienced any business interruption. Moving on to our strong Q4 results, I will provide a review of our fourth quarter performance and provide an update on key business initiatives, including the integration with Thomas. Then I will turn the call over to Jim for a more in-depth review of our financial results and outlook. We had a strong Q4 with revenue of $67.1 million as we continued to see rapid adoption of our marketplace by both buyers and sellers, as well as completing the strategic acquisition of Thomas on December 9. Excluding Thomas, Xometry revenue grew 66% year-over-year to $63 million and increased a strong 11% quarter-over-quarter. Thomas revenue in Q4 from the time of the acquisition was $4.1 million. While we completed the acquisition a little more than three months ago, our integration efforts are off to a strong start. I will outline our progress and roadmap later in the call and in our earnings presentation. Q4 Xometry revenue growth was driven by continued robust growth in active buyers and the rapid adoption of the platform by larger accounts across both North America and Europe. The Xometry marketplace provides flexibility and instant access to a large set of seller capabilities. Additionally, we provide our sellers convenient access to supplies, enabling them to lower their cost of operations. We also improved their cash flow through our basket of fintech products. In Q4, active buyers increased 49% year-over-year. We saw strength across many verticals, including consumer products, robotics, medical devices and electronics and semiconductors, as well as ongoing strength in general manufacturing. Additionally, we drove robust growth within existing accounts powered by our land-and-expand strategy and an increase in large orders, including production. The number of accounts with the last 12-month spend of at least $50,000 increased 80% year-over-year to 701, adding a record 99 accounts to that metric in Q4. Given the success of our land-and-expand strategy, we are investing to expand our enterprise sales effort in the near term. Within our large and rapidly growing active buyer base, we have a significant opportunity to become an enterprise solution embedded in product design and procurement workflows. In October, we launched Version 2.0 of the Xometry app for Autodesk Fusion 360, a leading CAD design platform. Version 2.0 offers manufacturability feedback and multiple part upload features, improving the user experience for engineers and designers working in Fusion 360. We continue to expand our seller services revenue, including improvements to our supplies business and our basket of fintech products. The usage of our financial products continues to improve, including InstantPay, which launched in the fall. Our financial products improved sellers' cash flows and engagement levels. Our international business continues to deliver strong growth driven by the team in Europe. In Q4, revenue in Europe increased over 300% year-over-year. Additionally, in Q4, we hired a general manager for our Asia Pacific business to quickly scale up our team and platform. We expect to formally launch a localized marketplace in that region by the end of Q1 and begin taking orders in Q2. We have a tremendous opportunity for international expansion and are investing to drive future growth. International revenue grew over 400% to $16.2 million for 2021, up from just over $3 million in 2020. Currently, over 90% of our revenue is generated in the U.S. We see an enormous global opportunity, and as with other leading online marketplaces, international revenue could be up to 40% or more of total sales over the next several years. On top of strong revenue growth, gross profit grew 121% year-over-year. Excluding Thomas, Xometry gross profit dollars increased 83% year-over-year and 20% from Q3 to Q4 2021, driven by improvements in pricing and seller matching in our AI-powered marketplace. As our marketplace continues to scale and as the number of transactions grow, our machine learning becomes smarter, driving better matches for buyers and sellers and helping improve gross margins. At the same time, we continue to ramp up our network of active sellers, which further enables our marketplace to successfully match supply and demand and improve gross margins. Over these strong financial results, in Q4, we made three acquisitions, including Big Blue Saw, FactoryFour, and Thomas to improve our marketplace experience for buyers and sellers and strategically transform our market and growth opportunities. Thomas is a leading online platform for industrial product sourcing, supplier selection, and marketing services. The addition of Thomas accelerates the growth of Xometry's marketplace, creating exceptional scale of buyers and manufacturers. We have established an end-to-end suite of seller services, including digital marketing products and advertiser services. Thomas is accretive to our margins and accelerates our path to profitability. We are executing against our integration plan as we now go to market as one company. We have integrated our teams, centering them around marketplace and seller services. We have a robust product roadmap focused on driving more buyers and sellers to the marketplace as we strive to become an enterprise solution for both. For buyers, we expect to integrate our instant quoting technology in the Thomas platform in Q2, opening up Thomas' 1.4 million-plus registered users and 20 million annual sourcing sessions to our marketplace. The technology behind this integration is based on our Xometry Everywhere initiative, which can be integrated in minutes to unlock Xometry's instant quoting on virtually any website. We are launching Xometry Everywhere later in March. Additionally, in Q2, we will expand our quoting capabilities into new categories based on the data and suppliers from the Thomas network. Buyers will not only be able to choose from expanded categories and processes, but will also be able to more easily find local suppliers and an expanded set of certifications. Also, buyers will be able to choose from over 45,000 diversity-certified suppliers, a category that is increasingly important to enterprise buyers. Also, by the end of Q2, we will rollout our One Identity Single Sign-On. Our buyers will be able to seamlessly purchase across Xometry's instant quote and Thomas RFQ with a single sign-on. One Identity will create a unified shopping cart across platforms to easily facilitate purchase and payment. For sellers, we introduced a new supplier analytic dashboard in the Thomas platform, which provides real-time data on buyers that are in the market for supplier services and the buyer's engagement with the supplier's profile. Recently, we introduced a self-service option for sellers to purchase Thomas advertising services on the Thomas platform. Our new self-service option removes friction for new customers and introduces a new entry price point for our marketing and advertising service offerings. The new dashboard and self-service options are foundational components of our strategy to significantly grow the number of premium suppliers and the frequency at which they actively engage with the Thomas platform. We expect to rapidly expand the number of premium sellers in the platform from roughly 5,000 today, given that there are 500,000 registered sellers on the platform. Also, for sellers, we will release a new version of our order management software in Q2 to integrate seamlessly with the Xometry marketplace and the Thomasnet.com platform, giving suppliers a one-stop view into all their orders. At the end of Q2, we expect to launch a freemium version of the software as we look to drive deep adoption within our seller base. The operating system will serve as the platform to deliver our basket of seller services to our base of manufacturers and drive further engagement in our marketplace. We expect that our product release schedule will drive additional growth and revenue synergies for the balance of 2022. We remain confident in our plan to deliver up to $400 million in revenue in 2022, which Jim will provide more detail on later in the call. We have limitless opportunities to fuel our growth. This year, we will expand our marketplace domestically and abroad and deliver additional services to buyers and suppliers. Our TAM is over $2 trillion in the massive $35 trillion global manufacturing industry. We will continue to invest to further capitalize on our position as the leading two-sided marketplace. In 2020, our revenue was $141 million. In 2022, we expect that to nearly triple to $400 million. And at the same time, we expect gross profit dollars to grow over fourfold with significant gross margin expansion, and we're just getting started. With that, I'll turn the call over to our CFO, Jim Rallo, for a closer look at fourth quarter financial results and our business outlook.

Thanks, Randy, and good afternoon, everyone. As Randy mentioned, we had a strong fourth quarter and we're expecting continued significant revenue and gross profit growth in Q1 and 2022. We generated Q4 revenue of $67.1 million, up 77% year-over-year, excluding Thomas. Xometry generated revenue of $63 million, a 66% revenue growth year-over-year. This increase was driven by strong growth in the number of active buyers, resulting from our continued investment in sales and marketing as we leverage our attractive unit economics, as well as existing buyers increasing their spend on the platform. In Q4, Thomas contributed $4.1 million in revenue from the time of acquisition on December 9, 2021. In Q4 2021, our KPIs are reported for Xometry on a stand-alone basis, excluding Thomas. Q4 active buyers increased 49% year-over-year to 28,130. In Q4, the percentage of revenue from existing accounts was 95%, underscoring the efficiency and transparency of our business model that leads to increasing account stickiness and spend over time. We believe the repeat purchase activity from existing accounts reflects the underlying strength of our business and provides us with substantial revenue visibility and predictability. Once an account joins our platform, we aim to expand the relationship and increase engagement and spending activities from the account over time. The number of accounts with the last 12 months spend of at least $50,000 on our platform reached 701 at the end of Q4 2021, up 80% year-over-year. Q4 gross profit was $20.9 million, an increase of 121% year-over-year. Gross profit margin was 31.2%. Excluding Thomas, Xometry gross profit margin was 27.5%, up 250 basis points year-over-year compared to 25% in Q4 2020. Q4 gross margin for Xometry increased 190 basis points from Q3 2021, excluding Thomas. As our marketplace continues to scale and as the number of transactions grow, our machine learning becomes smarter, driving better matches for buyers and sellers and increasing our gross margin over time. Moving on to Q4 operating costs. Q4 operating costs include Thomas from the date of the acquisition. Q4 2021 total operating expenses increased 131% year-over-year to $43.5 million. On a non-GAAP basis, Q4 operating expenses increased 103% year-over-year. Q4 2021 operating expenses included $5.7 million of transaction costs related to acquisitions and stock-based compensation expense of $2.6 million that is allocated across our SG&A lines. Additionally, Q4 operating expenses include approximately $2.2 million of public company costs and $1.1 million related to our charitable contribution. Within our operating expenses, sales and marketing is our largest variable component. Given our large and expanded TAM of $2 trillion, we will continue to invest in growing our marketplace of buyers and sellers. Non-GAAP sales and marketing costs were $12.4 million in Q4, an increase of 91% year-over-year, driven by continued investment to expand our network of buyers and sellers. Our hiring of additional salespeople and 1.4 million from the Thomas acquisition, our adjusted EBITDA loss for Q4 was $11.9 million or 17.7% of revenue. Thomas was not material to the Q4 adjusted EBITDA as the acquisition occurred on December 9. Our Q4 adjusted EBITDA loss was approximately $1.8 million higher quarter-over-quarter due to additional public company costs and investments in sales and marketing and international expansion in Asia Pacific and the United Kingdom. One note on GAAP EPS. Our Q4 GAAP EPS included $5.7 million in transaction-related costs, which are excluded from Q4 adjusted EBITDA. Turning to segment reporting, it is worth noting that the majority of Thomas revenues are in the U.S. In Q4, revenue from our U.S. and Europe operating segments was $61.8 million and $5.3 million, respectively. Segment loss from our U.S. and Europe operating segments for Q4 was $21.1 million and $2.8 million, respectively. We continue to invest in our European business, which grew over 300% year-over-year in Q4, with improving gross margins as transaction volumes increased. At the end of the fourth quarter, cash and cash equivalents and marketable securities were $116.7 million, with no debt. In early February, we raised approximately $278.9 million in net proceeds from our convertible notes offering. Now moving on to guidance. We expect Q1 2022 revenue in the range of $81 million to $82 million, representing year-over-year growth of 84% to 87%. Given the change of mix in our business with Thomas, for modeling purposes, we are providing gross profit margin ranges for Q1 and 2022. We expect Q1 gross profit margin in the range of 38% to 39%. Starting with Q1 2022 financial results, we will provide additional disclosure for marketplaces and supplier services. We report revenue and cost of goods sold for each. Thomas will be included in supplier services. We expect operating leverage to improve quarter-over-quarter in Q1 and through 2022. In Q1, we expect adjusted EBITDA loss to be in the range of $12.5 million to $13.5 million as we are increasing our spend by approximately $2 million. There are two primary contributors: First is an increase in compensation cost for individual employees reflecting the overall inflationary environment; second, we are making incremental investments in sales, technology, and international expansion. As Randy mentioned, we continue to invest in sales, including expanding our enterprise sales team based on the significant progress we are seeing in our land-and-expand strategy. Given the robust product release schedule that Randy mentioned, we are also investing more heavily in technology in Q1. Additionally, we invested to further drive international expansion, including the launch of our local marketplace in China and further expansion in Europe, specifically in the U.K. We will be live and up and running in China beginning in Q2. In Q1, we expect stock-based compensation expense to be in the range of $4 million to $5 million, which will be excluded from adjusted EBITDA. Q1 2022 stock-based compensation reflects the acquisition of Thomas. Additionally, as part of the IPO, we pledged 1% of the company's capitalization or approximately 403,000 shares to Xometry.org for charitable contributions to nonprofit organizations. As a result, each quarter, we will record a nonoperating charge through general and administrative expenses, which we will exclude from adjusted EBITDA. In Q4, this charge was $1.1 million, and we expect this number to be similar in Q1. Before I provide full year guidance, I want to take a moment to explain two factors influencing revenue for the balance of 2022 on top of our strong organic growth. First, we expect the majority of revenue synergies from the Thomas acquisition to be driven by the conversion of Thomas users to buyers on the Xometry marketplace. Based on the timing of our product release roadmap, we expect the revenue synergies to commence in Q2 and build through the balance of 2022. Second, we are seeing a notable shift to production orders from many of our biggest customers. This shift can be seen in the strong growth in accounts with last twelve months spend of at least $50,000. As a result, revenue from these accounts will ramp up significantly as the year progresses. For fiscal year 2022, we expect revenue in the range of $390 million to $400 million, representing year-over-year growth of 79% to 83%. We expect strong growth for the marketplace as well as strong growth for seller services, including the acquisition of Thomas. We are targeting a gross margin range of 37% to 39% for 2022. We expect 2022 adjusted EBITDA loss to be in the range of $32 million to $36 million. We expect operating leverage to improve going forward, especially in the second half of the year, driven by strong revenue and gross profit growth and the anniversary of our public company costs from our June 2021 IPO. On top of improving Xometry operating leverage, we expect improving profitability for Thomas. We expect to be profitable on an adjusted EBITDA basis in 2023. With that, operator, can you please open up the call for questions.

Our first question comes from Sterling Auty with JPMorgan.

So to start, I'd be curious about the very significant increase in the number of sellers. What are you seeing that's attracting more sellers to the network before you even get the benefit of potentially Thomas sellers coming on to the marketplace?

Sterling, it's Randy, and great to speak with you. So I think it's a number of factors, really. One is, I think, sellers are attracted to our tremendous customer base and the opportunity irrespective of their own sellers, particularly what they've historically done to get work at any time. We've also been making terrific improvements to user experience for them, and our matching algorithms continue to get better and better. So when a seller does come to our marketplace, they're more likely to find something that fits right into their sweet spot. And then on top of that, we've been expanding our basket of seller services, and that's also very attractive. So between finding them great customers and as we are reliable as we scale, we get more and more of that, and giving them more and more value-add services to make their businesses better, I think that's creating a lot of goodwill and attraction by them.

That makes sense. And then one follow-up. Can you maybe help us understand, you open to it a little bit in the prepared remarks, but maybe go a little bit further around the impacts that you're seeing on the business from the tight supply chains that continue?

Xometry has a robust business model that has remained unaffected by events such as COVID, supply chain challenges, and geopolitical issues. We've outlined several reasons behind this resilience. Primarily, most of our operations are conducted domestically, allowing us to provide customers with access to localized networks. This situation has reinforced the importance of having options like Xometry for sourcing, especially as global circumstances grow more unpredictable and complex. Consequently, we have observed a significant increase in accounts with spending exceeding $50,000, as more customers are increasingly relying on us as their primary supply chain partner.

Our next question comes from Eric Sheridan with Goldman Sachs.

I hope everyone is well on the team. Maybe two, if I can. First, coming back to Thomas. Can you talk a little bit more about how the revenue contribution builds as we move through the year? What's sort of the base case assumption by the company? And what could cause that base case assumption to have variability as you execute moving through the year? That would be #1. And #2, bigger picture question. Any update on international expansion, how you are thinking about the international opportunity in the years ahead?

Yes. Eric, just on Thomas, we have a lot of new products coming out that's going to help grow their revenue as we get through 2022. But when you think about the business, just go back to our prepared remarks that the revenue synergies are really accruing from us converting the Thomas buyers onto the Xometry platform. So that's the way to think about the growth outlook for the balance of the year.

And just to add to that, Eric, if you look at our product roadmap, and I know we threw a lot at people, but if you look in the slide deck, we're launching something called Xometry Everywhere that's going to launch momentarily here at the end of this quarter. We're using that technology to embed our instant quoting engine in Thomasnet. And so as we talk about converting that 1.4 million registered Thomas users and Xometry buyers, it will be right there in their environment. And again, we're going to be releasing the technology behind that in other places later this month, so we'll be ready to go for next quarter, and that will be very helpful.

Yes, Eric, this is Jim. Regarding our international expansion, I have a couple of updates. As Randy mentioned earlier, we have launched in China and have already completed a transaction there. This is significant for us because, while we have built a strong network of sellers in China, we have not yet established a buyer network. We currently have a team on the ground in China and plan to grow that team significantly over the next few quarters. The market opportunity in China is substantial given the size of the GMP there. In Europe, our main office is located in Germany, which serves as our corporate headquarters on the continent, but we are also expanding our sales team in other countries. The U.K. has become one of our larger sales groups, and we are additionally launching initiatives there. Our strategy is centered on land-and-expand; we are now established in Asia with our headquarters in Shanghai and will continue to grow in China. Furthermore, we are investing in Europe to further our expansion there.

And just to add to that, Eric, the site in China has just launched, so you can go to xometry.asia, and we're up and running there. I'm very excited about that.

Our next question comes from Brian Drab with William Blair.

Regarding your last comment, Jim, my question is whether you still anticipate breakeven in 2023 in terms of EBITDA, to which you responded affirmatively. However, it seems a bit challenging to envision this after noting the guidance of negative $34 million EBITDA at the midpoint for 2022. Can you elaborate on what will help you achieve this? Is it primarily the revenue growth in 2023, along with presumably some leverage and a slowing down of expenses rather than a significant increase? What can you share to provide more clarity on how we can reach breakeven?

Yes, Brian, I understand your question. We expect to achieve significant synergies in 2023 from Thomas and are preparing for that. When I mention ramping down, I really mean the adjusted EBITDA loss expected throughout next year, but we are confident we can reach our target. To clarify, when I refer to that target, I mean profitability on an adjusted EBITDA basis. I'll let Shawn provide more details on this.

Brian, the way to think about it is you're seeing really strong growth in revenue and stronger growth in gross profit dollars. And if you map that out for the next several quarters against a lot of fixed costs in our operating model, especially in our G&A, and we anniversary the big step up in public costs in the middle of last year, you're going to see significant operating leverage in the second half of 2022, and that's going to be your glide path to take into 2023. So we can take a little bit of that offline, but that's the basic picture.

Yes, that's really helpful. And then just one follow-up for now. In the second quarter, you're going to insert the quoting engine or have the quoting engine go live in Thomas. I'm just wondering, can you talk a little bit about what that will look like? Like what services will we be able to go find that quoting engine available for? And then I don't know if you could also comment on what else are you having to do to get that to work in terms of getting sellers that have been on the Thomas platform to participate?

Yes. And Brian, just before I answer, you talk about participate as in taking work from Xometry customers?

Yes. I'm just thinking in the old days, in the Thomas model, they would get just connected. Seller gets connected with someone. Now the seller is getting work through a quoting engine. So it's a different for them, and I'm trying to picture that again.

Yes. So let me answer on both questions for you. So in terms of putting the technology, the instant quoting technology into Thomasnet, as I kind of said earlier, we're going to be launching Xometry Everywhere very soon, and that is the underpinning of what we're going to be using to place that into Thomasnet. So we're very confident from a tech perspective that, that works. And that will offer, Brian, all of our current services that we have on Xometry.com today. Those will all be offered in that. We also mentioned in the roadmap that we're going to be expanding the breadth of those services, leveraging in large part the terrific seller or manufacturing base that resides in Thomas. So you will see the existing geometry quoting engine be embedded in Thomas, and then you'll see later in the quarter us expand the processes that we offer there. So that's on the customer side. And just from a tech perspective, we've got that down. We're feeling very good about that, and we'll make sure we have a good user experience for their registered users, Thomas registered-users. On the seller side, supplier side, we also talked about releasing for FactoryFour one pane of glass to enable Thomas-listed suppliers to get RFQs and to get work from Xometry. So think about that supplier. He or she has got the ability with a click of the button to not only accept RFQs from people going direct, but also if they want to get work from Xometry, it's also one click of the button. So we're making that experience really easy for them, and we're putting it all in one place. So they're not having to swizzle between both. And in that one pane of glass, they can also manage their own work as well. So that's why we're giving the system away as we talked about on a premium basis, and so that will be available by the end of Q2 to all of the listed suppliers in Thomas.

Our next question comes from Matt Hedberg with RBC Capital.

Randy, I guess, given some volatility in underlying commodity prices, how does your model work from a pricing perspective? Maybe if there's a longer lead time and it's based on a set commodity price that changes dramatically. Just sort of curious how that relationship works for the buyers and the sellers.

Yes, it's important to understand that we adjust our pricing model weekly. This approach accounts for any variations in raw materials or labor costs. When we provide a quote to our customers, we immediately give a corresponding quote to the sellers and manufacturers, ensuring both sides are coordinated. The buyer's quote is based on our predictions of seller prices. By continuously updating our model with new data every week, we refine the prices offered to both buyers and sellers. This process allows us to become increasingly efficient as we gather more data and attract more buyers. Consequently, even amid inflation, our gross margins are improving, and we're experiencing substantial business growth. The use of machine learning that updates weekly is why we've seen minimal impact.

Got it. That makes a lot of sense. Jim, thinking about the impact of Thomas on 2022, when you announced the acquisition, you mentioned it generated about $67 million in trailing 12-month revenue. Was the baseline assumption that Thomas revenue would grow roughly in line with Xometry's core revenue?

Not exactly. Let me explain that. We said we would expect the combined business to have a similar growth rate to what we've experienced in the past. We will leverage the synergies with the sellers and buyers of Thomas. Most of those transactions will take place on the Xometry marketplace. Therefore, on a combined basis, we do expect growth to continue, and we don't foresee any issues with that. We are fundamentally changing how Thomas operates from a transactional perspective. It hasn’t functioned as a transactional marketplace before, and as Randy mentioned in his remarks, that is one of the advantages of the synergies we will observe.

Our next question comes from Nat Schindler with Bank of America.

Yes. With the recent change in commodity prices, which has been rather fast and volatile. What is the chance and what mitigates your impact to gross profit when you give a guaranteed price ahead of time before a contract is completed?

We update our pricing on a weekly basis using machine learning, which allows us to adjust our pricing model accordingly. This process ensures that our prices reflect any fluctuations in raw materials, labor costs, and other factors. When a buyer visits our site, we provide them with current pricing that considers what we believe manufacturers can produce within that timeframe. This simultaneous pricing strategy helps us maintain our gross margins, even in varying macroeconomic conditions, as we gather more data and attract more active buyers. We believe we are well-positioned to mitigate risks associated with inflation since we effectively price for both buyers and sellers at the same time.

What percentage of a typical contract is made up of raw material? Is it primarily labor? Or is it mainly something else?

It's a small part of it, so. It's not a big part of it.

So obviously, extreme volatility even in this on relatively short-term contracts when it's only a small percentage of the total, it's not going to have a big effect on gross profit no matter what and your engine already accounts?

That's exactly right.

Our next question comes from Karl Keirstead with UBS.

Okay. Great. Maybe a couple. Jim, during your remarks, when you were discussing your revenue guidance of $390 million to $400 million, you mentioned that you were considering a shift in production orders. If I heard you correctly, you suggested there might be a change in the buyer mix towards some of the largest customers. Can you clarify what you meant by that and how it might affect revenues and profitability?

Yes. When considering production orders, they are delivered over specific time frames. We recognize revenue when we ship these orders. This allows us to predict more accurately since we know when and how much we will ship. It's similar to a SaaS model for manufacturing, as we have that forecasting in place. These orders are generally larger. Larger orders can be delivered in one quarter, or they might extend into another quarter. It's important to clarify that we recognize revenue at the time of shipment. Additionally, if we look at accounts with expenditures over $50,000, both the total amount and the number of such accounts are significantly increasing, which reflects the growing presence of larger manufacturing runs in the market.

Yes. And Karl, just to jump in a little bit. So we've added production-level manufacturing technologies to the Xometry marketplace, like injection molding, like die casting, like stamping. And so we've really seen greater adoption of that as we go deeper into our customers, becoming more of an enterprise solution. They're embracing those. And those technologies are creating these production orders. So for example, we're doing a lot more injection molding of medical devices, we're doing stamping for electric vehicle companies. So that's an exciting trend for us, and we expect that trend to continue as customers embrace us more and more.

And really Karl, this is what we've been talking about for a while, which is the evolution of the marketplace.

Our next question comes from David Silver with CL King.

I guess, the first question, I'd like to follow up, I think it was Jim who mentioned the overall strategy of converting Thomas users over to the Xometry platform. And I think you mentioned as one element of that or a key element is Xometry Everywhere function. But I'm just wondering what other elements to that strategy do you expect to implement to kind of drive that adoption from the Thomas base of users over to Xometry? And in particular, I mean, I think, I understand why the sellers would be quite enthusiastic about the combination. But just curious how you're thinking about getting those buyers that, to this point, are not paying directly for the use of the service to become paying users on the Xometry platform?

Yes, that's a great question. Let me discuss the 1.4 million registered users. To start, Xometry recently achieved a record number of active buyers in Q4, totaling 28,000. For context, while Thomas has 1.4 million registered users and has been in business for 100 years, many people are still unaware of Xometry. By integrating Xometry Everywhere and our technology into Thomasnet, we can immediately expose those Thomas users to our services even though they may not be familiar with us yet. This presents a fantastic opportunity, and we aim to create a user-friendly experience for purchasing on Thomasnet. Additionally, we have other tools in place to simplify the process for Thomas users. We offer integrations with popular CAD programs like SOLIDWORKS and recently announced improvements for Fusion 360. More integrations are on the way, and we're also directly integrating with our buyers' ERP systems. We've successfully completed integrations with platforms such as Coupa and Ariba, making it easier for Thomas users to connect with us, whether they are on Thomasnet, using CAD programs, or working within their ERP systems. They will be able to find and convert to Xometry seamlessly.

Thank you. And that concludes today's conference call. Thank you for participating. You may now disconnect.
