Thrive Holdings raises $2B at $12B valuation to push AI into accounting, IT, and construction

Thrive Holdings just pulled in $2 billion at a $12 billion valuation, with SoftBank, D1 Capital Partners, and Altimeter Capital writing checks. The firm operates like a private equity shop with an AI twist: it buys traditional businesses — mostly accounting and IT firms so far — then embeds AI directly into how they work. The model has quietly scaled to more than 70 companies across two platforms, Current and Shield.

Current, the accounting arm, now spans over 50 firms and 2,000-plus professionals. Its TaxAI agents processed more than 7,000 tax returns at 98% accuracy, cutting prep times by over 30% at participating firms. Shield, the IT division with roughly 20 companies, claims help desk resolution times have improved by 36x, and the number of custom AI agents deployed doubled in just the last month. Those are the kind of numbers that make investors overlook the fact that Thrive is essentially betting on operational turnaround through software.

The OpenAI connection runs deep. Thrive Holdings spun out of Thrive Capital, one of OpenAI’s major backers. In December 2025, OpenAI took an ownership stake in the firm and agreed to send employees into Thrive’s portfolio companies to accelerate adoption. That hands-on implementation model has become a business category of its own — OpenAI and Anthropic have both partnered with large PE firms to launch The Deployment Company and Ode with Anthropic, respectively. Thrive is effectively a proof point for that thesis.

Wednesday’s raise funds a third vertical: regulatory services for the built environment. Founding member Anuj Mehndiratta framed it as “the work required to get physical assets approved, built, certified, and kept in operation.” Think data centers, manufacturing, healthcare, power, water, transportation — all bottlenecked by local, technical, and regulatory complexity. Kareem Zaki, another founding member, said AI partnered with experts could “compress regulatory bottlenecks” while keeping safety standards high. The pitch is credible because the accounting rollout already demonstrated that pattern works. The risk is whether a model built on tax returns and help desk tickets translates to permitting, inspections, and compliance tracking — processes with far more regulatory teeth and professional liability attached. Thrive is about to find out.
