Josh Warren is a seasoned financial and strategic leader with deep experience across asset management, financial technology and capital markets.

Viswanathan continued, “On behalf of our entire team, I want to thank Helen for her partnership and significant contributions to FactSet. Over the past several months, Helen has played an important role in ensuring continuity and supporting a smooth transition following my joining the company. She has been an integral member of our executive team, helping position FactSet as an industry leader. As CFO, she advanced the company’s financial processes and infrastructure, including disciplined value-based pricing and the transformation of financial systems, and we are well placed to build on that progress as we move forward.”
