Paris start-up Opio raises €4 million for AI that speeds up acquisition audits

The story so far, in brief; the legwork, and the full article, stay with the original outlet.

Opio, a Paris start-up founded in 2025 by Tristan Fulchiron and Olivier Chancé, has raised €4 million from Frst, Seedcamp and GFC.

Before anyone buys a company, auditors spend weeks gathering and checking its accounts, largely by hand. Opio's software does the gathering and checking, which it says saves transaction services teams 27 per cent of their time.

Forvis Mazars Group and BDO are customers, and teams in 15 countries use it. Angels include Pennylane's Arthur Waller and Dust's Stanislas Polu. Revenue from outside France is 15 per cent; the target is 50 per cent within a year.
