“Can the exclusive services partner for Workday's HR & finance customers become the regulated financial-infrastructure provider underneath the Workday tenant?”
Founded in 2008 as the first Workday-exclusive BPaaS partner, OSV built patented in-tenant technology to run payroll, tax, benefits, and AP directly inside customers' Workday tenants. Over time it layered on payments infrastructure (Invoice Pay, myFlexPay card, myFlexWallet, earned wage access) that turned it from a services firm into a de-facto financial-services provider for the Workday ecosystem. In 2026, TA Associates took a majority stake and OSV stood up its own OCC-chartered national trust bank (OSVTB) — a structural move that brings its $250B+ in annual treasury flows under direct federal oversight rather than continuing to rely solely on partner-bank rails.
