Fangtooth Analytics

Fangtooth Analytics is building an AI-assisted financial analytics platform that runs natively inside Microsoft Excel, automating the manual data formatting and wrangling that eats up finance teams' time. It lets users build financial schedules, pull live data into spreadsheets, and drill down to transaction-level detail — with AI analysis that keeps proprietary data inside the spreadsheet.

Finance professionals in due diligence, M&A and audit still live in Excel, but most AI tooling asks them to move their data elsewhere — a non-starter when the data is sensitive. Fangtooth's bet is that the winning approach meets these teams where they already work, rather than forcing a new environment.

The company was founded in 2026 by Stuart Daniells and Matthew Saturno, the latter a CPA and CBV, to replace hours of mechanical spreadsheet work with outputs generated in minutes. The founding team is building around a simple frustration: too much finance analysis is manual formatting rather than actual insight.

With a founder credentialed as a CPA and CBV, the team brings direct familiarity with the valuation and accounting workflows Fangtooth targets. The company says its privately deployed AI keeps client data from ever leaving the Excel environment — a design choice that reflects who they're building for.
