Frst and Seedcamp put 4 million euros into cutting 27% off financial due diligence

A time saving inside a professional services firm either goes to the client as a smaller bill or stays with the firm as spare capacity. Opio's customers are the transaction services teams whose reports set the terms of the deal ^[6]. Twenty-seven percent of a 40-hour week is 10.8 hours ^[4]. Hand those hours to the client and the engagement shrinks. Keep them and the firm has to find more mandates to fill them. Forvis Mazars Group and BDO, the two firms Opio names as partners, are the ones who make that choice ^[7].

The succession number attached to the round belongs to Bpifrance: 370,000 French businesses changing ownership by 2030 as owners retire. Among them are 58,000 small and medium enterprises and 1,200 mid-sized companies, with around three million jobs involved ^[9]. Those two brackets add to 59,200, or 16% of the headline figure ^[2]. Divide the jobs by the companies and the average business in the wave employs about eight people ^[3]. I would not expect a company that size to commission the kind of report a Forvis Mazars transaction services team produces. That makes the 16% the part of the forecast that reaches Opio's buyers. Spread evenly, the full 370,000 comes to roughly 74,000 ownership changes a year ^[5].

The harder cost is jurisdictional. The product is already used by teams in 15 countries, including Germany, Canada, Senegal and Hong Kong, each with its own accounting standards ^[8]. "It is not typical for a company such as ours to expand on such a scale," co-founder Tristan Fulchiron said ^[12]. Four million euros across ten people is 400,000 per head ^[1], and every country's rule set competes for that money with sales, support and the model itself.

Fulchiron says no company of Opio's scale competes directly in transaction services, and names two close rivals ^[13]. Tracelight in the UK raised $3.6 million in seed funding in 2025 to build AI tools for financial modelling in Excel ^[14]. "The company is mainly aimed at strategic advisory firms, working with McKinsey rather than Deloitte," he said ^[15]. DataSnipper, the Dutch audit-automation company that reached a $1 billion valuation on Excel-based tools, is "currently incorporating generative AI into their products, so we might become a competitor there at some point too," he said ^[16].

The pitch is a claim about sequence. "Lawyers, consultants and developers have all been through their own AI revolution - it's now time for auditors carrying out financial due diligence to have theirs," Fulchiron said ^[10]. He spent ten years as a civil servant running technology projects for France's Ministry of Defense and Ministry of the Interior, one of which let citizens file police complaints online ^[19]. He puts auditor resistance in the same bracket as police resistance: "You have to help people understand how their job will be transferred, not replaced" ^[11]. Sia Houchangnia, a partner at Seedcamp, said the firm backed Opio "as they attempt to solve one of the biggest bottlenecks in financial services that nobody is talking about" ^[17].

On what is disclosed, the 27% is a result reported by the vendor from teams inside its partner firms. It converts into revenue only through a seat or engagement contract, and that price is not public ^[3]. The other reading is that Bpifrance's retirement wave lifts deal volume faster than firms can hire juniors. Then the freed hours are sold as capacity and the fee question never arises ^[9]. If Forvis Mazars or BDO cut what they charge for due diligence after adopting the tool, the 27% went to the deal clients. Opio is then a software line inside a fee pool that is getting smaller.
