DealGlass, Inc.

the diligence engine for private credit

The big labs approach Excel like any other code RL problem, not a financial one

@dealglassinc and @acephalt benchmarked Tetra, Opus 4.7, and GPT-5.5 for long-horizon financial modeling and found severe auditability gaps with the openpyxl/Python strategy

i quit my quant job at SIG to build @DealGlassInc

we just topped SpreadsheetBench Verified, mogging Opus 4.6, GPT-5.4, and Shortcut.

generic spreadsheet agents optimize for speed at the expense of quality. we built Tetra to underwrite billions.
