Paris-based AI startup Opio has raised €4 million in its first funding round to expand its technology for automating financial due diligence during mergers and acquisitions. The round was backed by Frst, Seedcamp, and Global Founders Capital, alongside angel investors including Pennylane co-founder Arthur Waller and Dust co-founder Stanislas Polu. Founded in 2025, Opio aims to reduce the large amount of manual financial-data preparation traditionally handled by transaction services professionals before they can begin deeper analysis.
Automating Financial Due Diligence
Financial due diligence typically requires transaction services teams to collect, verify, reconcile, and organize large volumes of company accounting data before assessing the financial health of an acquisition target. Opio automates much of this preparatory work by structuring and checking financial information, allowing auditors and advisers to focus earlier on analysis, professional judgment, and discussions with company management. According to the company, its technology can free up approximately 27% of the time currently spent by transaction services professionals on these processes.
Building Technology for Audit Teams
Opio was founded by Tristan Fulchiron and Olivier Chancé, two engineers with experience spanning government technology projects, startups, and data infrastructure. Fulchiron previously led technology initiatives for the French government, including work connected to the Ministry of Defence and Ministry of the Interior, while Chancé has built engineering and data teams at companies in France and Brazil. Their platform is designed to complement rather than replace professional auditors by handling repetitive data-processing tasks while leaving financial interpretation and client-facing work to human specialists.
Early International Adoption
The startup has already secured major audit and advisory firms including Forvis Mazars Group and BDO as customers, with its technology being used by transaction services teams across 15 countries. Opio says this international adoption requires its software to operate across different accounting environments and reporting standards while maintaining the accuracy expected in acquisition-related financial analysis. The company currently generates around 15% of its revenue outside France and plans to increase that figure to approximately 50% within the next year.
Expanding Across European Markets
The newly raised capital will support Opio's expansion in key European markets, particularly the United Kingdom and Germany, while strengthening its engineering and commercial teams. The company is also evaluating opportunities in additional markets, including Spain, as it builds toward broader international expansion and a potential future entry into the United States. Investors are backing the company as demand grows for specialized AI systems capable of addressing complex workflows that require both automation and high levels of financial accuracy.
Beyond Transaction Services
Opio plans to extend its technology beyond acquisition-related due diligence and into other areas of financial auditing, including statutory audit and account certification. The company has already begun working with auditors on certification-related use cases and expects to introduce a second product in early 2027 as part of this broader strategy. Its longer-term ambition is to provide specialized infrastructure connecting general-purpose artificial intelligence with the precise financial workflows used by auditors and accounting professionals.
Growing Demand for Audit Automation
The startup is entering the market as both artificial intelligence adoption and ownership transitions among European businesses increase demand for more efficient financial analysis. In France alone, Bpifrance estimates that hundreds of thousands of companies could change ownership by 2030 as existing business owners retire, potentially increasing the volume of transactions requiring detailed financial due diligence. Opio is positioning its platform to help audit firms handle this workload without proportionally increasing the amount of manual preparation required from junior professionals.
With €4 million in new funding, Opio is seeking to establish financial due diligence as another professional workflow where specialized AI can deliver measurable productivity improvements. Its early adoption by major audit firms and deployment across multiple countries give the company a foundation for further expansion into broader financial auditing activities. As Opio develops additional products and enters new markets, its growth will depend on demonstrating that automation can increase efficiency while maintaining the accuracy and professional judgment required in financial reporting and M&A transactions.
