What In Extenso does
In Extenso is a French chartered accountancy and professional services group, established around 1995, delivering accounting, tax, legal, wealth management, insurance brokerage, real estate, finance, innovation, hospitality, recruitment, and social-economy services through a network of wholly-owned subsidiaries. Its primary client base comprises French business owners (chefs d'entreprise), whom it serves across the lifecycle of their enterprises—from creation and growth through sale or transfer and retirement—via a 360-degree, multidisciplinary advisory approach anchored in regulated designations (CIF, IAS).
The group's principal technology asset is fulll, a French-language SaaS platform founded in 2021 that delivers accounting and payroll software to French accounting offices. Fulll sits alongside the Inexweb client portal and is positioned to capture demand from France's mandatory e-invoicing rollout, serving an addressable market of approximately 19,000 accounting firms and 3.8 million SMEs. The wealth management division, In Extenso Patrimoine, augments its advisory practice with a content-and-thought-leadership engine including a podcast ("Questions d'Argent"), expert-authored blog, webinars, ebooks, and client events such as the Journées du Patrimoine.
Revenue is generated through two principal streams: professional-services fees for chartered accountancy, wealth advisory, tax optimization, business succession, insurance brokerage (IEP Courtage), and real estate intermediation (IEP Immo), alongside a subscription/recurring revenue stream from the fulll SaaS platform. Distribution occurs through direct field-sales advisory engagements with business owners, cross-referrals across the group's divisions, and—in the case of fulll—a strategic partnership with Visma, which acquired a minority stake in March 2026 to accelerate platform development. Public pricing is not disclosed, and detailed financial performance is not publicly reported.

In Extenso competitors and assessment
Company assessmentEmerging players
- Pennylane: Paris-based fintech offering accounting and financial management SaaS for French SMEs and their accountants; partial overlap with fulll in serving accounting offices preparing for e-invoicing.
Direct peers
- Rothschild & Co: French heritage, independent wealth and asset management group with strong business-owner and intergenerational wealth expertise; directly comparable in client profile and advisory orientation.
- Lombard Odier: Independent European private bank with deep business-owner and wealth planning expertise; similar structure as a privately held, multi-jurisdictional wealth advisory boutique.
- Cegid: Leading French cloud accounting, payroll and tax SaaS provider for SMEs and accounting firms; the primary domestic software competitor to fulll for French accounting-firm workloads.
- Pictet Group: Swiss privately owned wealth manager with a long-standing focus on entrepreneur and family-wealth advisory across Europe; comparable multi-generational business-owner client base and discretionary advisory model.
Broad incumbents
- Sage: Global incumbent in accounting/payroll SaaS, including a significant French accounting-firm footprint; broader portfolio competitor to fulll in the same end market.
- Natixis Private Wealth Management: Private banking arm of Groupe BPCE serving French business owners, entrepreneurs and family wealth planning; structural overlap with In Extenso Patrimoine's entrepreneur-facing wealth services.
- Indosuez Wealth Management (Crédit Agricole): Crédit Agricole's wealth arm serving French and European business owners and HNW clients; comparable in target customer (French entrepreneurs) but part of a full banking group with broader product and custody capabilities.
- BNP Paribas Wealth Management: French banking incumbent with the largest domestic wealth management franchise; broadly comparable to In Extenso Patrimoine's business-owner advisory focus, with a much larger product shelf (banking, custody, lending).
Others
- KPMG France (Entrepreneur & Family Office advisory): Big Four firm offering chartered accountancy plus wealth/succession advisory to French entrepreneurs; adjacent rather than directly competing, but addresses the same business-owner wealth and cession needs.
