Opio raises €4M seed to automate financial due diligence for deal teams

Opio, a Paris-based AI startup founded in 2025, has raised €4 million in seed funding. The round was backed by Frst, Seedcamp, Global Founders Capital, Arthur Waller (Pennylane) and Stanislas Polu. No lead investor was disclosed.

What Opio does

Opio automates financial due diligence for transaction services teams at audit and advisory firms. Its platform collects, verifies and structures the financial data behind acquisitions — work auditors traditionally do by hand over several weeks. According to the company, the product saves those professionals around 27% of their time.

The company was founded by Tristan Fulchiron and Olivier Chancé.

Traction

Opio's customers include Forvis Mazars and BDO, and teams in 15 countries use its product.

Why it matters for acquisition

Financial due diligence is a labor-intensive, deadline-driven function inside audit and advisory firms. Opio's focus on collecting, verifying and structuring deal data positions it at the front end of transaction workflows, where speed and consistency directly affect how quickly firms can move on acquisitions.

With fresh seed capital, the company is funded to expand adoption among transaction services teams that already rely on manual processes.
