Basis Raises $100M at $1.15B Valuation to Expand AI Accounting Agents

New York-based Basis has raised $100 million in Series B funding at a $1.15 billion valuation, announced in a press release. The round was led by Accel, with participation from GV (Google Ventures), Lloyd Blankfein, and existing investor Khosla Ventures. Accel partner Miles Clements will join Basis’s board alongside Khosla Ventures’ Keith Rabois.

Basis develops AI agents that automate complex accounting workflows across client accounting, tax, and audit operations. The company says it is now working with about 30% of the top 25 accounting firms. Its agents operate autonomously over extended periods to complete tasks such as end-to-end tax returns, including a recent demonstration of a fully automated 1065 tax filing.

The new funding will be used to accelerate platform development and expand engineering and machine learning teams. Basis also runs an internal initiative, called Atlas, to build its own AI agents for internal functions such as engineering and sales.

Founded by Matthew Harpe and Mitchell Troyanovsky, Basis provides AI-driven automation tools that integrate into accounting teams’ workflows to reduce manual work and improve efficiency.
