What Basis does
Basis, legally Essex Labs, Inc., is a New York-based AI company founded in 2023 that builds autonomous AI agents for accounting workflows. The platform deploys specialized agents across the four core practice areas of accounting firms: Client Accounting Services (CAS), Tax, Audit, and Advisory. Agents execute complex multi-step tasks end-to-end, including partnership tax returns (Form 1065), financial statement preparation, reconciliations, journal entries, and technical accounting memos, collaborating with human accountants at key decision points and delivering finished work for review. Notable technical components include the autonomous 1065 tax return agent (an industry first), an internal Mantis orchestration layer for incident response, a Clueso bug-investigation agent that resolves approximately 78% of incidents on first pass, and a Satellite unified MCP server fronting 36 third-party providers with centralized security policy and OAuth-based access controls. The platform is SOC 2 Type II, ISO 27001, and ISO 42001 certified.
The company monetizes through enterprise SaaS subscriptions sold to accounting firms, with custom quote-based pricing, annual billing, and waitlist-based onboarding rather than published tiers. Distribution is sales-led, combining direct enterprise field sales with a dedicated Deployed Intelligence professional services team that guides workflow redesign at customer organizations, supported by Accounting Solutions Consultants and Sales Engineers. A Baker Tilly strategic collaboration extends reach to thousands of accounting clients through partner-led deployment. The customer base spans approximately 30% of the Top 25 US accounting firms and a broader footprint across the top 100, with named customers including Boulay, Clark Nuber, UHY, Berkowitz Pollack Brant, Wiss, MarksNelson, Pinion, and WilkinGuttenplan.
Basis has raised approximately $137.6 million across three rounds: a $3.6 million seed led by Better Tomorrow Ventures (October 2023), a $34 million Series A led by Khosla Ventures (December 2024), and a $100 million Series B led by Accel and GV (Google Ventures) at a $1.15 billion post-money valuation (February 2026), achieving unicorn status. The Series A announcement reported 10x revenue growth, and the company reports 20-50% efficiency gains for customers using its agents.

Basis competitors and assessment
Company assessmentDirect peers
- Vic.ai: AI-powered autonomous invoice processing and accounting workflow platform targeting enterprise accounting teams. Direct competitor in the AI-agent-for-accountants category with a similar focus on autonomous workflow completion for finance and AP.
- Pilot: AI-augmented bookkeeping and back-office accounting service for startups and SMBs. Comparable in delivering AI-driven accounting outputs and serving firms/teams that outsource or automate core accounting workflows.
- Botkeeper: AI bookkeeping and automation platform for accounting firms, combining machine learning with human accountants. Overlaps directly with Basis's pitch of automating repetitive accounting work within firm practices.
- Digits: AI-native accounting and financial-close platform for startups and small businesses. Comparable as an AI-first accounting product aiming to autonomously run bookkeeping, close, and reporting tasks.
- Numeric: AI-powered accounting close and reporting platform automating journal entries, reconciliations, and flux analysis for accounting teams. Directly comparable as an autonomous-accounting agent aimed at finance and accounting workflows.
Broad incumbents
- Karbon: Workflow and practice-management platform purpose-built for accounting firms. Adjacent category leader for accounting-firm operations, increasingly layering AI features as competitive overlap intensifies.
- Canopy: Practice management and client-engagement platform for accounting and tax firms. Comparable buyer base (accounting firms) and overlaps with Basis on automation and AI-driven workflow features inside practices.
- Intuit (QuickBooks): Dominant SMB/cloud accounting platform with embedded AI agents (Intuit Assist) across bookkeeping, tax, and advisory. Largest incumbent in the AI-for-accounting space with massive distribution, though focused on smaller end of the market than Basis's Top 25 firm base.
- Xero: Cloud accounting platform with AI-driven automation (Xero Analytics Plus, JAX) for accountants and SMBs. Comparable in providing AI-enhanced accounting workflow capabilities, though primarily serving smaller firms and direct SMBs.
