Sana

Can an AI knowledge assistant become the primary interface through which enterprise employees access and act on all internal information — and ultimately the AI layer Workday's workforce platform is built on?

The story

Founded in 2016 as Sana Labs, an AI-powered personalized learning platform, the company evolved from pure LMS/e-learning into a broader enterprise 'knowledge assistant' that indexes company information and enables employees to search, chat, and automate workflows via AI agents. After raising $130M in total venture funding — including a $55M Series C in late 2024 — Sana was acquired by Workday, integrating its AI knowledge infrastructure into Workday's HR and enterprise software suite. The embedded finance footprint is limited primarily to treasury/ledger operations (via Modern Treasury) supporting the SaaS business itself, rather than financial products sold to end users.
