Microsoft has acquired Fintool, a San Francisco startup that builds AI agents for investment research, and is moving its team into the Office Product Group. The deal became public on April 17, 2026, when Sumit Chauhan of Microsoft's Office Product Group welcomed Fintool co-founder Nicolas Bustamante and his team in a LinkedIn post.
Terms were not disclosed. Microsoft did not issue a press release, and no purchase price, deal structure or closing date was reported.
According to Pulse 2.0, Microsoft plans to build Fintool's technology into Office and Microsoft 365, starting with tools for financial services professionals and later extending them to other industries. The Fintool team is expected to work on product development inside the Office platform.
What Fintool built
Fintool went through Y Combinator's Winter 2023 batch, where it described itself as a financial copilot for institutional investors and "ChatGPT on top of financial documents". Its software uses AI agents to read company filings, analyze earnings call transcripts, pull research together and point out possible investment insights.
The fifth version of the product, released in early 2026, was built as a fully agentic system, Pulse 2.0 reported. It could produce discounted cash flow (DCF) models in Excel, earnings presentations in PowerPoint and research memos in Word on its own.
That output maps directly onto the three main Office applications, which helps explain the fit with Microsoft. Pulse 2.0 said the product had found users among professional investors at hedge funds, asset managers and investment banks, but no customers were named.
Pulse 2.0 described the product as automating qualitative financial analysis: the reading, comparing and summarising work that sits around the numbers in an analyst's day.
“This addition is a perfect complement to our overall strategy and will benefit our customers by pairing the specialization of Fintool with the capabilities of the Office suite.”
Why Microsoft is buying
Microsoft did not explain the deal beyond the LinkedIn post. Fintool's output was Excel models, PowerPoint decks and Word memos, the same applications the Office Product Group is responsible for, so the team arrives with agents that already produce finished financial work inside those file formats.
"This addition is a perfect complement to our overall strategy and will benefit our customers by pairing the specialization of Fintool with the capabilities of the Office suite," Chauhan wrote in the post announcing the deal.
Pulse 2.0 said the acquisition fits Microsoft's broader effort to make Microsoft 365 more useful to knowledge workers, with finance as the first target market.
The founders and the funding
Fintool was founded in 2023 by Nicolas Bustamante and Edouard Godfrey. Y Combinator's company directory lists the startup as acquired, with a team of six people based in San Francisco.
Bustamante had built a company before. In 2016 he co-founded Doctrine, a Paris-based legal search engine that uses artificial intelligence, and he served as its chief executive until 2020, according to Wikipedia.
Doctrine later expanded from France into Italy, Germany and Spain, and Wikipedia reports that RELX, the owner of LexisNexis, agreed to acquire it. Bustamante had left the chief executive role in 2020, three years before starting Fintool. At Y Combinator, Fintool's primary partner was Nicolas Dessaigne, and the accelerator lists the company under artificial intelligence, finance and trading.
Apart from its Y Combinator backing, Fintool's funding history has not been publicly reported. No other investors, round sizes or valuations were disclosed.
What is still unknown
The deal follows the pattern of a small, focused team moving inside a large product group while the price stays private. With six people listed by Y Combinator, Fintool was small even by early-stage standards, and VectorShift's deal record lists neither a value nor advisers.
It is not yet clear how quickly Fintool's agents will appear inside Microsoft 365, or whether they will be offered as a separate product or as features within Excel, PowerPoint and Word. No timeline was given.
