interop.io Information

interop.io was formed in June 2023 through the merger of Finsemble and Glue42, creating a global leader in application interoperability and enterprise AI enablement for capital markets and beyond. Our mission is to go beyond basic application connectivity by transforming open standards like FDC3 into seamless, high-impact Straight-Through Workflows. The result? Greater business agility, smarter user experiences, and tighter operational control. At the core of our offering is io.Connect, which powers thousands of desktops across the financial industry. It enables clients to unify legacy, web, and AI-enabled applications into a single, intuitive interface — so teams can focus less on switching contexts and more on getting work done. interop.io is headquartered in the U.S. and employs over 110 full-time engineers and R&D staff across New York, London, and Sofia. Our clients include leading buy-side and sell-side firms and technology vendors such as Citi, Fidelity, Millennium, JPMorgan, Broadridge, FactSet, and IRESS.
