Collective raises $100M to build an AI financial OS for solo businesses

How the $100 million is structured

According to Collective, the Series B portion of $40 million was led by General Catalyst, QED Investors, and Gradient Ventures. Intuit Ventures, FT Partners, and SemperVirens also took part in the round.

The remaining $60 million is a growth facility from General Catalyst's Customer Value Fund (CVF), intended to fuel customer acquisition. Collective says the funding will also speed up its product development in banking and insurance.

Pranav Singhvi, Partner and co-head of CVF at General Catalyst, said the fund looks for companies with "high-quality unit economics and a large market opportunity." He added that solo businesses are "one of the most dynamic segments of the economy."

The back-office problem for solo operators

Collective points to a growing market. The company says the U.S. now has 30 million solo businesses. It cites a recent Stripe report stating that the number of solo operators generating $1M per year doubled between 2023 and 2025, while those earning $10M per year tripled.

As these businesses grow, Collective argues, the back office becomes the bottleneck. Owners often piece together disconnected software for bookkeeping, payroll, and taxes, and pay high fees to traditional CPAs. According to the company, that costs them hundreds of hours on administrative work and leads them to miss tax savings.

What the platform does

Collective describes its product as a full-stack financial operating system that works in the background. Instead of handing owners more software to run, the company says its platform combines AI with financial infrastructure to anticipate, coordinate, and execute workflows on its own. The listed features are:

• Business setup: automates entity formation such as LLCs.
• Accounting: categorizes expenses and reconciles accounts.
• Invoicing: streamlined invoicing tools.
• Payroll: salary processing aimed at compliant tax savings.
• Taxes: autonomous preparation, filing, and ongoing optimization.
• Business insurance: integrated coverage options.
• Health insurance: access to coverage options for solo founders.
• Support: a human team powered by AI that, according to Collective, resolves 50% of support requests autonomously while maintaining 4.5 star satisfaction.

CEO and co-founder Hooman Radfar said traditional accounting firms scale by adding people, while "Collective scales with intelligence." He said the aim is for a Business-of-One to access the financial capabilities of a much larger company without building the team behind it.

Growth claims and what comes next

Collective says it is the largest platform serving solopreneurs and that its ARR is growing 120% year-over-year. The company estimates it has saved solopreneurs $350 million in taxes to date, and says its highest-income users save up to $40,000 per year. These figures come from the company itself and are not independently verified in the announcement.

One customer, graphic designer Eddy Adams, said that through an s-corp setup he saves tens of thousands of dollars in taxes every year, adding: "Their service pays for itself!"

For solo business owners, the planned expansion into banking and insurance suggests Collective wants to bring more of the financial stack onto a single platform. The $60 million facility earmarked for customer acquisition indicates the company intends to grow its member base further.
