Basis, an AI platform for accountants, has secured $100 million in Series B funding, achieving a valuation of $1.15 billion. The round, led by Accel, aims to accelerate the company's mission of deploying autonomous AI agents to tackle complex accounting tasks. This significant investment underscores the growing confidence in AI's potential to transform the professional services industry.


Addressing an Industry in Crisis

The accounting profession is currently facing unprecedented challenges, marked by a severe, decades-long talent shortage and escalating client demands. This strain has resulted in considerable margin pressure for firms and widespread burnout among staff. Consequently, many accounting firms are now forced to turn away potential clients, limiting their growth and operational capacity.

The Rise of Autonomous AI Agents

Basis addresses these issues by developing "long-horizon" AI agents that autonomously manage complex accounting workflows from start to finish. These agents operate continuously to complete tasks across tax, audit, and advisory services, delivering finished work for final review. The company recently showcased this capability by demonstrating the first AI to complete an entire 1065 tax return.

Strong Investor Confidence and Strategic Vision

The new $100 million funding round, led by Accel with participation from GV and Khosla Ventures, highlights strong investor belief in Basis's approach. Miles Clements of Accel praised the company for being "years ahead in accounting AI," expressing confidence in its ability to define the category. This capital infusion is a testament to the platform's perceived market leadership and potential.

The investment is further bolstered by a roster of prominent backers from the technology and finance sectors, including Lloyd Blankfein and leaders from OpenAI, Stripe, and Google. As part of the deal, Accel's Miles Clements will join the board, adding his expertise alongside Khosla Ventures' Keith Rabois. This strategic backing provides Basis with significant industry guidance and a robust network.

Future Plans and Agent-Native Culture

Basis will allocate the new funds to accelerate the development of its AI platform and expand its engineering and machine learning teams. The primary objective is to enhance the capabilities of its agents to perform increasingly sophisticated workflows with greater accuracy. This strategic investment is crucial for maintaining its competitive edge and scaling its operations.

In a novel approach, Basis is also cultivating an "agent-native" culture within its own operations through a dedicated team called Atlas. This team builds internal agents to streamline functions like engineering, sales, and talent acquisition, reflecting a deep-seated belief in its own technology. This practice showcases the company's commitment to pioneering the future of AI-driven organizations.


With its new funding and advanced AI technology, Basis is poised to fundamentally reshape the accounting industry. The company aims not only to drive significant efficiencies but also to empower accountants, improve their quality of life, and enable firms to offer higher-value services. This initiative marks a pivotal step toward a future where AI agents are an integral part of all knowledge work.
