“Can a performance-management SaaS become the strategic command center for HR by layering AI coaching on top of engagement, review, and compensation data?”
Founded 2011 by David Hassell as a lightweight weekly check-in tool ('15 minutes to write, 5 to read'). Over the 2010s, expanded into a full continuous performance management suite (reviews, OKRs, 1-on-1s, engagement surveys). Post-2022 Series C, pivoted upmarket into mid-market/enterprise HR and layered AI on top (Amaya, Kona AI Coach, AI-assisted reviews). No embedded finance ambitions — 15Five is a pure HR/performance SaaS that explicitly positions itself as 'distinct from HRIS/payroll'.
15Five integrates with ADP Workforce Now, BambooHR, Dayforce, Deel, Google Workspace, Hibob, Justworks, Namely and 18 others.
The Embedded Finance Index 2026 maps 3 layers in 15Five's stack: Payments / PSP (Stripe and Zuora); Unified APIs (Merge and Truto); Accounting (ADP Workforce Now, BambooHR, Dayforce, Deel and 22 others).
15Five was founded by David Hassell and is founded in 2011, headquartered in San Francisco, California, United States.
15Five has raised ~$90M+ in total (latest round: Series C, 2022).
15Five's acquisitions include Kona (2024) and Emplify (2021).
