In Extenso Corporate Finance

What In Extenso Corporate Finance does

In Extenso Corporate Finance is the M&A advisory division of France-based In Extenso Group, providing sale/transmission, acquisition, fundraising, and valuation advisory services to small and mid-cap companies (PMEs) across France. The practice operates through 12 regional offices staffed by 40 dedicated M&A experts and has completed over 1,000 transactions, holding the #1 rank in French M&A Small Cap league tables in 2022 and 2023. Revenue is earned through bespoke, transaction-based advisory fees; no standardized pricing is publicly disclosed and engagements typically run on multi-year mandates tied to deal lifecycle.

The broader In Extenso Group, under which the Finance division operates, is a €650M-revenue (2026) private French professional services group founded in 1991 with 7,300 professionals. The group integrates chartered accountancy, legal services (In Extenso Avocats), M&A advisory (In Extenso Finance), and a cloud-native accounting and payroll SaaS platform called fulll that targets France's ~19,000-firm accounting market ahead of mandatory e-invoicing reforms. Core technology assets include the fulll cloud SaaS platform (wholly-owned by In Extenso) and the integrated regional office network across France, Belgium-Luxembourg, Switzerland, and Spain. In 2024, the group extended its European footprint via the majority acquisition of Swiss fiduciary Fidexpert, and in 2026 the Visma group took a minority stake in fulll to support continued development of the SaaS platform.

The go-to-market is sales-led and enterprise-field-sales-oriented, relying on deep relationships with SME owner-operators and intra-group referrals from the broader accounting, legal, and SaaS practices. The customer base is highly diversified across verticals (construction, software/IT, industrial manufacturing, engineering, veterinary, biotech, transport), and deal sizes are concentrated in the small-cap segment. In 2026, governance was restructured with Christophe Del Toso and Yoann Melloul appointed co-Directeurs Généraux and Antoine de Riedmatten assuming the presidency.
