French fintech startup Opio has raised €4 million in funding from Frst, Seedcamp and GFC, as it looks to expand technology designed to automate time-consuming parts of financial due diligence.
Founded in Paris in 2025 by Tristan Fulchiron and Olivier Chancé, Opio is building specialised software for auditors working on company accounts ahead of acquisitions. The startup focuses on the part of due diligence that often involves collecting, checking and restructuring large volumes of financial information before professionals can begin analysing it.
The company says its technology can reduce the amount of time Transaction Services professionals spend on this work by 27 per cent.
Opio targets the manual work behind financial due diligence
Financial due diligence can take auditors several weeks, with a significant amount of the process traditionally handled manually.
Opio’s platform is designed to collect, verify and structure financial data before deeper analysis begins. The aim is not to replace the judgement involved in an audit or transaction review, but to reduce the repetitive preparation work that comes before it.
Fulchiron said junior professionals currently spend a considerable portion of their time gathering, checking and adjusting data. By automating those steps, Opio wants teams to move more quickly to areas that require human judgement, including analysing a business, interpreting its financial performance and working with clients and management.
The company maintains that the core analytical work remains with professionals, particularly when numbers need to be understood within the context of a company’s operations and industry.
Forvis Mazars and BDO among Opio users
Opio has already attracted customers in the professional services sector, including Forvis Mazars Group and BDO, alongside several other firms.
Its product is currently being used by Transaction Services teams across 15 countries, giving the young Paris startup an international footprint less than two years after its founding.
The company’s investor base also includes several angel investors with backgrounds in technology and finance. They include Arthur Waller, co-founder and CEO of Pennylane, and Stanislas Polu, co-founder of Dust. Former employees of HSBC, Deutsche Bank and KKR have also invested in a personal capacity.
Opio sets sights on the UK and Germany
International expansion is now becoming a bigger part of Opio’s growth plans.
The company currently generates 15 per cent of its revenue outside France and wants to increase that figure to 50 per cent within a year. France will remain an important market, while the UK and Germany have also been identified as key areas for growth.
Opio is also preparing to broaden its product offering. A second product is planned for early 2027, while its longer-term ambition is to move beyond transaction-related due diligence and address a wider range of financial auditing work.
That expansion has already started in one area, with Opio working with statutory auditors on certification assignments.
Engineering experience behind the startup
Opio’s founders bring experience from both government and technology companies.
Before starting Opio, Tristan Fulchiron led engineering organisations for the French state, including work at the Ministry of Defence, and later served as a digital adviser to the Minister of the Interior.
Olivier Chancé, meanwhile, has built engineering and data teams at startups and scaleups in Brazil and France, including experience as a founding engineer.
Their company is now concentrating on an area of professional services where large amounts of structured financial information still need to be prepared before auditors can apply their expertise.
With fresh funding from Frst, Seedcamp and GFC, Opio is seeking to turn that narrow focus into a broader auditing platform while expanding its presence beyond its home market.
