Opio raises €4M to automate the grunt work of financial due diligence

AI for financial due diligence startup Opio has raised €4 million from investors Frst, Seedcamp and GFC to develop its specialised technology that helps auditors examine a company's accounts ahead of an acquisition. 

Opio was founded in Paris in 2025 by Tristan Fulchiron and Olivier Chancé. Fulchiron previously led engineering organisations for the French state, including at the Ministry of Defence, before serving as digital adviser to the Minister of the Interior. Chancé has built engineering and data teams at startups and scaleups in Brazil and France, including as a founding engineer.

Opio collects, verifies, and structures data, saving transaction services professionals 27 per cent of their time in a process that traditionally takes auditors several weeks and is largely done by hand. 

“A large share of junior professionals' time currently goes on collecting, checking and adjusting data before it can be interpreted. By automating that part of the work, Opio lets them spend their time earlier on analysis, judgement and client relationships,” says Fulchiron.

“The core of the job remains human: understanding a business by talking to its management, interpreting its numbers with professional judgement, setting them in the context of its sector.” 

Opio has already won over two major players in the sector, Forvis Mazars Group and BDO, along with several other firms. Transaction Services teams in 15 countries use its product.  Its angel investors include:

• Arthur Waller, co-founder and CEO of Pennylane,
• Stanislas Polu, co-founder of Dust, and former staff of HSBC, Deutsche Bank and KKR investing in a personal capacity. 
  

The company currently generates 15 per cent of its revenue outside France and aims to increase this to 50 per cent within a year, with France, the UK, and Germany key markets for growth. A second product is already planned for early 2027. Ultimately, the company wants to expand across the full scope of financial auditing and has already begun working with statutory auditors on certification work.
