Basis, a New York City-based AI startup focused on accounting automation, has raised $100 million in Series B funding at a valuation of $1.15 billion, according to an announcement on February 24, 2026. The round was led by Accel and Google Ventures, with participation from Khosla Ventures and former Goldman Sachs CEO Lloyd Blankfein.
The funding round — which brings total capital raised to $138 million — validates the growing conviction that AI agents will fundamentally reshape accounting firm operations. For the virtual assistant and outsourcing industry, the implications are both a challenge and an opportunity.
What Basis Does
Founded in 2023 by Matthew Harpe and Mitchell Troyanovsky, Basis develops AI agents that automate structured accounting workflows across tax preparation, audit procedures, and advisory functions. Unlike simple automation tools, Basis agents operate autonomously — in some cases running for hours on complex tasks — and present finished work for human accountant review.
The company's most notable technical achievement: it recently demonstrated the first AI agent to autonomously complete an end-to-end 1065 tax return (partnership tax return), a complex multi-schedule filing that typically requires significant professional time.
Key platform capabilities include:
- Tax preparation automation: AI agents handle data extraction, form population, schedule preparation, and compliance checking
- Audit workflow support: Automated work paper preparation, sample selection, and testing procedures
- Advisory analytics: Financial analysis, benchmarking, and reporting that supports client advisory services
- Cross-engagement learning: The platform improves its performance across a firm's client base over time
Adoption by Major Firms
The market traction is significant. Basis reports that approximately 30% of the top 25 accounting firms are already using its platform. These are not pilot programs — they are production deployments integrated into daily firm operations.
Bloomberg's coverage notes that the rapid adoption reflects accounting firms' acute need for efficiency tools in the face of persistent talent shortages and compressed engagement timelines.
Early adopters report 20-50% efficiency gains across practices — a range that varies by engagement type and firm complexity but consistently delivers meaningful operational improvement.
Vinod Khosla, whose firm participated in the round, stated that he expects Basis to "drive the same step-change in accounting that software engineering saw in 2025" — a reference to the transformative impact of AI coding assistants.
What This Means for Accounting Outsourcing
The Basis funding round raises a critical question for the accounting outsourcing industry: does AI agent technology replace the need for human virtual assistants, or does it amplify their value?
The Finance Story's analysis examines this question directly and concludes that the impact will be nuanced:
Functions at Risk of AI Displacement
- Routine data entry and categorization
- Standard tax return preparation for simple filings
- Basic bookkeeping reconciliation
- Formulaic financial reporting
Functions Where Human VAs Become More Valuable
- Client communication and relationship management
- Complex judgment calls requiring contextual understanding
- Exception handling and error investigation
- Multi-system coordination across client tech stacks
- Advisory support that requires understanding client goals
- Quality review and oversight of AI-generated work
The pattern mirrors what has occurred in other industries: AI automates the structured, repetitive elements of work while increasing demand for the human judgment, communication, and coordination capabilities that virtual assistants provide.
The Accounting Talent Shortage Context
Basis's rapid adoption is not occurring in a vacuum. The accounting profession faces a well-documented talent crisis:
- CPA exam candidates have declined for multiple consecutive years
- Major firms are struggling to recruit and retain experienced professionals
- The average age of practicing CPAs continues to rise
- Busy season workloads remain unsustainable for many professionals
In this context, AI agents like Basis do not eliminate the need for human support — they enable existing professionals to serve more clients and handle greater complexity. Virtual assistants who specialize in accounting operations become the essential human layer that manages client relationships, coordinates workflows, and handles the tasks that AI agents cannot.
The Hybrid Future
The $1.15 billion valuation signals investor confidence that AI-augmented accounting is the future. But outsourced accounting trend analysis suggests the winning model is hybrid: AI agents handling structured computation and compliance work, while human virtual assistants manage client interactions, exception processing, and quality oversight.
For accounting firms evaluating their operational model, the strategic question is how to combine:
- AI agent platforms like Basis for structured, computation-heavy workflows
- Virtual assistant support for client management, coordination, and judgment-intensive tasks
- In-house professionals for advisory services, complex planning, and client relationships
Firms that effectively integrate all three layers will capture the efficiency gains that AI provides while maintaining the client service quality that drives retention and referrals.
Implications for VA Service Providers
For companies offering virtual assistant services to accounting firms, the Basis funding round is a signal to evolve — not retreat. The most valuable accounting VAs in 2026 are those who:
- Understand AI tool outputs and can review, validate, and communicate results to clients
- Manage the coordination between AI systems, firm professionals, and clients
- Handle the exception cases and complex situations that AI agents flag but cannot resolve
- Maintain the client relationship continuity that drives long-term engagement value
The $100 million investment in Basis validates that accounting is entering a new operational era. Virtual assistant providers who adapt to that era will find more demand, not less.
