New York-based startup Basis has closed a substantial $100 million Series B funding round, reaching a post-money valuation of $1.15 billion. The investment will fuel the expansion of its autonomous artificial intelligence systems specifically engineered to handle sophisticated accounting workflows, positioning the company as a key player in transforming a traditionally labor-intensive industry.
Launched in 2023 by co-founders Matthew Harpe, who serves as CEO, and Mitchell Troyanovsky, Basis set out with a clear vision: AI agents would soon play a central role in knowledge work, with accounting emerging as one of the earliest and most impactful areas for adoption.
The field’s structured data, regulatory demands, and critical importance to businesses made it ripe for innovation, yet it remained underserved by advanced technology.
In three years, the platform has evolved rapidly, now capable of independently managing extended, multi-hour processes that mirror the capabilities of leading AI coding assistants but applied to financial operations.
The round was led by Accel, with strong support from GV (formerly Google Ventures), former Goldman Sachs chief executive Lloyd Blankfein, and existing backers from Khosla Ventures—including Vinod Khosla and Keith Rabois—who increased their commitments.
A group of additional participants joined, including tech professionals such as Nat Friedman, Daniel Gross, Aaron Levie of Box, Adam D’Angelo of Quora and OpenAI’s board, and others from Stripe, Replit, Hugging Face, and Amazon. Accel’s Miles Clements and Khosla’s Keith Rabois will join the board.
This brings Basis’s cumulative funding to roughly $138 million, building on a $3.6 million seed and a $34 million Series A completed in December 2024.
Accounting practices today grapple with chronic talent shortages, rising client expectations, and squeezed margins that contribute to staff exhaustion and lost opportunities.
Basis tackles these pressures head-on by embedding specialized AI agents into daily operations across client accounting services, taxation, and auditing.
The systems learn individual client nuances, coordinate complex tasks in the background, and produce finalized deliverables for minimal human review.
The company already partners with approximately 30 percent of the top 25 U.S. accounting firms, delivering measurable productivity lifts estimated at 20 to 50 percent in key areas.
A recent breakthrough underscores the technology’s maturity: Basis demonstrated the first AI agent to autonomously complete an entire end-to-end
Form 1065 partnership tax return—a key milestone for agentic AI in high-stakes environments.
Agents now routinely generate intricate journal entries, troubleshoot challenging reconciliations, draft technical memos, and more, with performance improving monthly at an accelerating pace.
Funds from the round will primarily advance platform development to support ever-more intricate workflows while scaling engineering and machine-learning talent.
The company is also pioneering an “agent-native” internal culture, deploying its own AI tools across operations to maximize speed and output.Industry observers note the broader momentum.
Accel partner Miles Clements highlighted Basis’s architecture for real-world deployment, calling it years ahead in the accounting AI space and capable of shaping the category’s future.
Vinod Khosla remarked that the platform is already reshaping workflows at leading firms and could mirror the efficiency gains software engineering experienced in 2025.
Harpe articulated the mission succinctly: the goal is to arm accounting professionals with the most capable and precise AI available, enabling firms to pursue fresh growth, deliver elevated client value, and markedly improve daily working conditions.
As agentic AI gains traction across professional services, Basis’s trajectory illustrates how targeted automation can alleviate longstanding bottlenecks in precision-driven sectors.
With this capital injection, the startup stands ready to deepen its footprint, potentially improving overall productivity standards for accountants and the businesses they serve.
