Microsoft acquires Fintool to supercharge Excel with financial AI agents

Microsoft has quietly expanded its AI portfolio by acquiring Fintool, a San Francisco-based startup specializing in AI agents for the financial sector

Microsoft has acquired Fintool, a startup known for building AI-powered research tools for finance professionals. While Microsoft neither officially announced the deal nor revealed its terms, Fintool's founder posted about the acquisition on X and their official website. This acquisition signals Microsoft’s growing ambition to improve Microsoft 365 experiences through the power of AI agents.

Fintool was founded in San Francisco by Nicolas Bustamante and Edouard Godfrey. The startup built AI agents that help investors and analysts handle qualitative financial research. Its platform was able to read earnings call transcripts, analyze company filings, synthesize research, and surface insights from them.

Earlier this year, Fintool V5 was announced, which enabled AI agents to work autonomously in the background on tasks such as building discounted cash flow models in Excel, preparing earnings presentations in PowerPoint, and more.

Since many Fintool customers already rely on Microsoft products in their daily workflow, integrating Fintool’s technology directly into Microsoft 365 is a logical step for Microsoft to take in the coming months.

Nicolas Bustamante, CEO and Co-Founder of Fintool, wrote the following regarding Microsoft's acquisition:

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.

Sumit Chauhan, President of the Office Product Group at Microsoft, welcomed the Fintool team to Microsoft with the following message:

Welcome Nicolas Bustamante and the Fintool team to the Office Product Group at Microsoft. 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.

Inside Microsoft, Fintool's team will focus on improving Office products for financial services, with the broader goal of expanding those capabilities to other industries as well.
