Investors

AccelGVKhosla VenturesLloyd Blankfein

Basis is a New York startup building AI agents that do accounting work, preparing financial statements, tax returns and audit workpapers for accounting firms. It became a unicorn in February 2026 with a US$100 million Series B led by Accel at a US$1.15 billion valuation, three years after its founding. This profile explains how Basis's agents work, who uses them, its funding and competition.

Basis's valuation

Basis's Series B of US$100 million was led by Accel, with GV, former Goldman Sachs chief executive Lloyd Blankfein and existing backer Khosla Ventures, at a US$1.15 billion valuation, according to Bloomberg and SiliconANGLE. Total funding reached about US$138 million, following a US$3.6 million seed round in 2023 and a US$34 million Series A in December 2024. We found no later round as of October 2026.

What Basis does

Accounting firms spend huge numbers of staff hours on repetitive work: gathering client documents, categorising transactions, reconciling accounts, preparing tax returns and building audit files. Basis's agents take on those tasks inside the firm's existing workflow. An accountant assigns work to an agent, which reads source documents, uses accounting and tax software, produces the output and documents its reasoning so a human can review it.

The company has demonstrated an agent completing a US Form 1065 partnership tax return without human help, according to Pulse 2.0. Basis says its platform is used by about 30% of the top 25 and 20% of the top 150 accounting firms in the US. The new money will expand engineering and machine learning teams and build agents for more complex work, according to Built In NYC.

Why accounting is ripe for AI agents

The accounting profession faces a talent shortage: fewer graduates are becoming certified public accountants while demand for tax, audit and advisory work grows. Firms struggle to staff busy season and many have turned to offshore teams. AI agents that can do junior-level work promise to ease that bottleneck and change the economics of firms that bill by the hour. Accounting also has clear rules, structured data and a strong review culture, which suits AI that drafts work for humans to check.

Founders

Mitchell Troyanovsky, the chief executive, and Matthew Harpe founded Basis in 2023. The company is based in New York and has hired accountants alongside engineers so that its agents reflect how the profession actually works.

Competitive landscape

Basis competes with accounting software vendors adding AI, such as Intuit, Thomson Reuters and Wolters Kluwer; with AI startups targeting tax and accounting; and with the in-house technology teams of the largest firms, some of which are building their own AI tools. It sits within a wider wave of AI for professional services that includes Harvey and Legora in law. See our guide to AI agent companies.

Risks

  • Accuracy and liability: errors in tax returns or audits carry legal and financial consequences.
  • Incumbent competition: the major software vendors own the systems accountants use daily.
  • Adoption pace: conservative firms may move slowly, especially in audit.
  • Regulation: standards bodies may set rules for AI use in audit and tax work.

Questions to ask

  • How much revenue does Basis generate, and how is it priced?
  • What share of tasks are completed without significant human correction?
  • How do firms' hours and margins change after adoption?
  • Which workflows beyond tax preparation is it automating?

Timeline in brief

  • 2023: founded; US$3.6 million seed.
  • December 2024: US$34 million Series A.
  • February 2026: US$100 million Series B led by Accel at US$1.15 billion.

Basis at a glance

Basis is a New York AI company founded in 2023 by Mitchell Troyanovsky and Matthew Harpe that builds AI agents for accounting firms, covering tasks such as tax returns, financial statements and audit work. It raised a US$100 million Series B led by Accel in February 2026 at a US$1.15 billion valuation, bringing total funding to about US$138 million, and says it is used by a large share of the top US accounting firms.

How firms use Basis day to day

In practice, an accounting firm connects Basis to the systems it already uses, such as its practice management software, document portals, general ledger tools and tax preparation software. A manager assigns a client engagement, for example preparing a partnership return or a set of monthly financial statements. The agent gathers the client's documents, extracts the figures, maps them to the right accounts and forms, flags anything unusual and produces a draft with notes explaining each step. A staff accountant or manager then reviews the work, as they would a junior colleague's, and signs off.

The value is in turning hours of preparation into minutes of review. During busy season, when firms are stretched, that can mean taking on more clients without hiring, or giving staff more time for advisory work that clients value more. Basis has emphasised that its agents leave an audit trail, so reviewers can see where each number came from, which matters for professional standards and for liability.

Valuation context

A US$1.15 billion valuation for a company three years old reflects how investors value AI agents that can replace billable work. Comparable professional-services AI companies, such as Harvey in law, have raised at far higher valuations on fast revenue growth. Basis's price implies investors expect it to become a core system for accounting firms, not just a productivity add-on. A next round would likely depend on how quickly its revenue grows across the top firms it already counts as users, and on whether it expands from tax into audit and corporate finance.

What to watch

Watch for a Series C, adoption by the largest audit firms, expansion into corporate finance teams and regulatory guidance on AI in accounting.

Takeaways

Basis is one of the leading bets on AI agents in professional services. Its rapid rise reflects both the talent shortage in accounting and investors' belief that agents can take on real, billable work.
