Basis Raises $100 Million at a $1.15 Billion Valuation to Scale AI Accounting Agents

The startup develops autonomous systems for multi-step accounting tasks used by major U.S. firms.

Overview

  • Accel led the Series B, with participation from GV, Lloyd Blankfein, and Khosla Ventures.
  • Basis offers agentic AI for accountants that automates financial statement preparation, tax filings, and expense tracking.
  • The company says it serves about seven of the top 25 U.S. accounting firms and plans to deepen tax and audit capabilities while expanding its machine learning and engineering teams.
  • OpenAI’s Prashant Mital said in a release that Basis has pushed the limits of its models on complex, economically valuable accounting tasks, a claim that aligns with the startup’s focus on long-horizon agents.
  • Basis reports an AI agent recently completed a 1065 partnership return, and the funding lands as investor interest surges in agentic AI competitors such as Accrual and Pennylane.
