Alt-X

About

Alt-X is building the Cursor for financial modeling in Excel, an Excel agent that you can actually trust. Private-market investing still runs on Excel. Every year, trillions of dollars in real estate and private-equity deals are underwritten through manual spreadsheet work — copying numbers from PDFs, CIMs, and data rooms into fragile models that analysts rebuild from scratch. Alt-X is the AI underwriting layer for Excel. It turns raw deal materials into clean, auditable financial models inside Excel, automatically extracting key metrics and generating institutional-grade underwriting models that analysts can immediately review and edit. Building reliable AI workflows for financial models is difficult. Underwriting models contain thousands of interdependent formulas across multiple sheets, and small errors can materially change investment decisions. Alt-X focuses on making model generation and data extraction reliable enough for real deal workflows, not just demos. We built our product to underwrite billions. Ryan Samadi (Stanford CS/AI, former Citadel trader) and Michael Wachsmann (Cornell CS, infrastructure engineer) have spent years building systems around financial data and modeling workflows. We have hundreds of millions in AUM using us already, and our users already prefer us to legacy cash flow modeling tools in the real estate space. Private markets remain one of the largest manual workflows in finance. Alt-X’s goal is to become the default infrastructure layer for underwriting private-market investments inside Excel.
