Updated July 3, 2026Basis builds autonomous, agentic AI that works alongside accountants and produces finished work for review — notably demonstrating an AI agent completing an end-to-end partnership (Form 1065) tax return. Founded in 2023 and headquartered in New York, Basis raised a Series B in 2026 with investors including Accel and GV, and is used by a meaningful share of the largest US accounting firms. It is a flagship of the agentic-accounting wave, framing its product as a capable junior that a human always reviews.
