Microsoft has acquired Fintool.

Every year, I go to Omaha to listen to Warren Buffett and Charlie Munger at the Berkshire Hathaway annual meeting. Buffett would describe his process: reading filings, analyzing businesses, building conviction one annual report at a time. Sitting there, it hit me. AI had already automated quantitative finance. The next frontier was qualitative analysis. That was the beginning of Fintool, in San Francisco, with my co-founder Edouard Godfrey.

We built agents that could read earnings calls, analyze filings, synthesize research, and surface signals that would take a human hours to find manually. Fintool became the daily research tool for thousands of professional investors across hedge funds, asset management, and investment banking. In January 2026, we launched Fintool V5: a fully agentic experience where an AI agent works autonomously in the background, building a DCF model in Excel, an earnings deck in PowerPoint, or a research memo in Word.

But something became clear very quickly. Many of our customers use Microsoft solutions as part of their daily workflows. When Microsoft approached us, the fit was obvious: knowledge workers are using Microsoft 365, and we should bring our expertise and IP there.

What excites me most is the focus. As a startup CEO, you do everything: fundraising, hiring, payroll, GTM, operations. Now I get to pour all that energy into what I care about most: product craftsmanship and quality. Our mission is to make Office products work brilliantly for financial services as well as other verticals and products to benefit all knowledge workers.

We also had an incredible fit with the team. Sumit Chauhan, who runs the Office Product Group, was an amazing partner from the start. The alignment with her and her team, including Brian Jones who leads Excel, made this feel right from day one.

To the Fintool team: Edouard, Jesse, Wei, Donovan, Ishan, Dak, and everyone who contributed along the way. Building this with you was the privilege of my career. Every shipped feature, every late night, every customer visit in St. Louis, Chicago, New York, Dallas. Relentlessly learning from customers and shipping. You made something real. I am proud of every one of you.

To our investors: Jean de La Rochebrochard and Emmanuel Seuge at Cassius, Deedy Das at Menlo Ventures, Nicolas Dessaigne at Y Combinator, and the dozens of angel investors and friends who bet on us. Most of them already backed my first startup, Doctrine, over ten years ago. Long term game, long term people. Thank you for taking that bet again. It meant everything.

To our customers, thank you for believing in us early, for giving us your trust, and for pushing us to build something worthy of your work. This acquisition is a direct result of the signal you gave us. None of this happens without you.

I hope that you will soon find in Office and Microsoft 365 the same level of craftsmanship and tailoring to financial services that you had in Fintool, and soon in other verticals too.

Now we build for everyone. I will share more on X and LinkedIn.
