The timing reflects surging investor interest in agentic AI systems designed to operate autonomously on complex tasks. "Agent-native operations are pushing startups toward higher output per employee, and in some cases smaller teams; the cost impact can be significant early on and could, at scale, mean more competitive market dynamics," Michael Ashley Schulman, partner and CIO at Running Point Capital Advisors, told Reuters

How AI Agents Automate Accounting Tasks Across Tax and Audit

Basis provides AI agent technology to accounting firms to help them complete tasks like preparing financial statements, filing tax returns and tracking expenses

1

. The platform is built around agent-based architecture that executes multi-step financial processes using large language models combined with rules-based controls and domain-specific accounting logic

3

.

These autonomous AI agents target labor-intensive tasks such as document review, reconciliation and tax preparation, areas where firms face staffing constraints and increasing compliance complexity

3

. The agents ingest structured and unstructured data from client documents, accounting systems and enterprise resource planning platforms, then analyze financial records, extract relevant fields, perform calculations and apply validation rules within predefined compliance frameworks

3

.

Basis focuses on building so-called long-horizon agents, which can work on complex accounting tasks for hours or even days, according to co-founder Mitchell Troyanovsky

1

. The startup recently built the first-ever AI agent that can autonomously complete a partnership tax return, a complicated filing that requires accountants to produce individualized tax documents for every partner in a business, track custom profit-sharing arrangements, and often file separately in multiple states

Addressing the Accounting Talent Shortage Through Workflow Automation

The platform addresses a longstanding accounting talent shortage that has plagued the industry in recent years

2

. Demand for accountants is expected to increase over the next several years according to the Bureau of Labor Statistics, yet fewer students are becoming accountants and more accountants are retiring or leaving the profession

1

.

Basis aims to supplement the shortage of accountants in the US and elevate the kinds of work that human accountants are able to do, said CEO Matt Harpe

1

. If rote tax returns and financial statements are automated, accountants can focus on higher-level work, helping clients make key decisions on tax strategies and capital allocations

.

Major Accounting Firms Adopt Agent-Based Workflows

Basis said its platform is used by about 30% of the top 25 accounting firms and 20% of the top 150 firms

1

. The company now serves approximately seven of the top 25 accounting firms in the U.S., deploying agents that complete complex accounting workflows end-to-end across their client accounting services, tax and audit practices

3

. Notable customers include Boulay PLLP, Clark Nuber PS, MarksNelson LLC, Pinion LLC and UHY LLC

3

.

"What stands out about Basis is how deeply they think about architecting and deploying real agents that do real work in the real economy," said Miles Clements, partner at Accel

3

. With the fresh funding, Basis plans to expand its customer base while going deeper on tax and audit capabilities, and aims to grow its machine learning and engineering teams

Financial Services Market Rattled by AI Advances

Investors are taking seriously the idea that AI could upend financial services. Earlier this month, wealth management stocks sank after the startup Altruist Corp. released AI agents for tax planning

. Days prior, shares of financial data providers fell when Anthropic dropped a new model that the company said could perform complex financial research

.

Basis isn't the only startup hoping to shake up the world of AI accounting. General Catalyst put $65 million behind Accrual, an AI accounting startup making software for accounting, earlier this month

1

. Accounting is one of the key industries targeted by AI-focused Thrive Holdings, and in January, French startup Pennylane raised €175 million ($204 million) in a funding round led by growth equity investor TCV

Venture funding for artificial intelligence-linked firms has climbed sharply in recent years, with AI startups capturing a growing share of global deal value as investors bet the technology will transform industries worldwide

2

. Agentic AI, which can plan, decide and act autonomously rather than simply respond to a prompt, has become one of the most sought-after categories in venture capital as investors focus on professional services
