Basis has raised $100 million in Series B funding at a $1.15 billion valuation, marking one of the largest recent rounds in accounting technology. The round was led by Accel through partner Miles Clements, with participation from GV and Lloyd Blankfein. Khosla Ventures, represented by Keith Rabois and Vinod Khosla, doubled down alongside other existing investors.

Other backers include NFDG, Better Tomorrow Ventures, BoxGroup, Avid Ventures, Kris Fredrickson, Aaron Levie, Adam D’Angelo, Amjad Masad, Claire Hughes Johnson, Clem Delangue, Eric Wu, Gautam Kedia, Jack Altman, Jeff Dean, Jeff Wilke, Kyle Vogt, Noam Brown, and Scott Belsky. Miles Clements will join the board alongside Keith Rabois.

Accounting Firms Under Pressure

The accounting sector is facing mounting strain. Talent shortages that have persisted for decades are intensifying. Client expectations are rising. Margins are tightening. Many firms report burnout among staff and are even declining new work.

Basis says it is now working with roughly 30 percent of the Top 25 accounting firms. Its agents are deployed across Client Accounting Services, Tax, and Audit practices, completing complex workflows end to end.

“What stands out about Basis is how deeply they think about architecting and deploying real agents that do real work in the real economy. Across multiple investments at the frontier of AI, we’ve seen the same pattern again and again: teams that get the fundamentals right tend to pull away quickly. Basis is years ahead in accounting AI, and we believe it has what it takes to define this category as it matures.”

Miles Clements, Partner at Accel.

The company recently demonstrated what it describes as the first AI agent to autonomously complete an end to end 1065 tax return. Agents operate continuously in the background, coordinating accounting tasks and delivering completed work for review.

“Basis is on the frontier of building production-grade, long-horizon agents. They’ve pushed the limits of what we thought our models could do on real-world, economically valuable, complex accounting tasks. They’ve been a great collaborator in helping us shape what the future of agents looks like,”

Where the $100M Will Go

Basis plans to use the new capital to accelerate platform development. The focus is on building more advanced agents capable of handling increasingly complex accounting workflows across tax, audit, and advisory services.

The company will also expand its engineering and machine learning teams. Hiring is expected to concentrate on talent that can improve model reliability, workflow depth, and enterprise integrations.

“Our sole focus is to equip accountants with the highest performing, most accurate AI for accounting and to empower firms to drive new growth, provide higher-value service, and improve accountant quality of life across every one of their practices,”

Matt Harpe, CEO and Co-Founder of Basis.

Inside Basis

Founded by Matthew Harpe and Mitchell Troyanovsky, Basis positions itself as an AI agent platform built specifically for accountants. Its agents are designed to understand accounting standards, learn client-specific requirements, and execute real tasks rather than simply assist with drafting.

“Basis is already radically changing how work gets done at the best firms, driving 20-50% efficiencies across practices. In 2026, we expect Basis to drive the same step-change in accounting that software engineering saw in 2025.”

Vinod Khosla, Founder of Khosla Ventures.

Accounting teams integrate Basis directly into their workflows, delegating time-consuming manual work while retaining review and approval authority. The company compares its approach to long horizon AI systems seen in coding platforms, but applied to structured financial processes.

Basis is also experimenting internally with what it calls an “agent-native” structure. A dedicated group named Atlas builds internal AI agents across engineering, sales, and talent operations.

“Basis is building the agent-native organization of 2030. We have too much to do in too little time, and are executing with rare clarity and speed.”

Investor Base and Funding History

Prior to this Series B, Basis was backed by Khosla Ventures, Accel, Better Tomorrow Ventures, NFDG, and BoxGroup, among others. The latest round significantly expands its capital base and strengthens ties to investors active across AI infrastructure and enterprise software.

The board now includes Accel’s Miles Clements and Khosla Ventures’ Keith Rabois, reinforcing investor involvement at the strategic level.
