Financial due diligence is one of the most time intensive stages of an acquisition, with transaction services teams often spending weeks collecting, checking and restructuring company data before meaningful analysis can begin. Paris based startup Opio is using artificial intelligence to streamline that preparation work, raising €4 million to develop technology for auditors and financial due diligence professionals.
Backed by Frst, Seedcamp and GFC
Opio’s funding round was backed by Frst, Seedcamp and GFC. The company was founded in Paris in 2025 by Tristan Fulchiron and Olivier Chancé, who bring experience across public sector engineering, startup technology and data infrastructure.
Fulchiron previously led engineering organisations for the French state, including work 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 experience as a founding engineer.
The founders created Opio around a central problem in financial due diligence: professionals often spend a large portion of their time preparing data rather than interpreting it.
Automating the Preparation Work
Opio’s platform collects, verifies and structures financial information so transaction services teams can work with more consistent and usable data.
In a conventional due diligence process, auditors and analysts may need to gather information from different files and systems, check its accuracy, reconcile inconsistencies and adjust figures before beginning their assessment. Much of this work is performed manually and can take several weeks.
Opio is designed to automate these repetitive stages. The company says its technology can save transaction services professionals approximately 27 percent of their time, allowing them to focus earlier on analysis, professional judgement and discussions with clients.
The platform does not seek to remove the human role from financial due diligence. Instead, it is intended to reduce the administrative workload that surrounds the core investigative process.
Keeping Human Judgement Central
Opio co founder and chief executive Tristan Fulchiron said junior professionals currently spend substantial time collecting, checking and adjusting data before it can be interpreted.
By automating these activities, he said, Opio enables teams to dedicate more time to analysing businesses, exercising judgement and building client relationships.
Fulchiron also stressed that understanding a company remains a human task. Speaking with management, interpreting financial results and placing figures within the context of a particular industry require experience and professional judgement.
This human centred approach positions Opio as an assistant for financial professionals rather than a replacement for auditors or transaction advisers.
Early Enterprise Adoption
Opio has already secured customers among major professional services firms, including Forvis Mazars Group and BDO. Its product is being used by transaction services teams in 15 countries, indicating that the company’s initial focus extends beyond the French market.
The startup’s angel investors include Arthur Waller, co founder and chief executive of Pennylane, and Stanislas Polu, co founder of Dust. Former professionals from HSBC, Deutsche Bank and KKR have also invested in the company in their personal capacities.
Expanding Across Europe
International growth is a key priority for Opio. The company currently generates 15 percent of its revenue outside France and aims to increase that share to 50 percent within the next year.
France, the UK and Germany are expected to be important markets as Opio expands its commercial reach. The startup is also preparing a second product for early 2027, suggesting that its product roadmap will extend beyond its current financial due diligence offering.
Over time, Opio plans to address a wider range of financial auditing activities. It has already begun working with statutory auditors on certification work, opening a potential path into additional audit processes.
With its new funding, Opio is seeking to build a broader AI infrastructure layer for financial professionals, helping firms handle complex financial information more efficiently while preserving the expertise and judgement that remain central to auditing and dealmaking.
