FIDAG

What FIDAG does

FIDAG is a privately held Swiss fiduciary (fiduciary, audit, tax, and consulting services) firm headquartered in Martigny, Valais, founded in 1959 by André Devanthéry and Gérard Pillet. The firm operates through 11 offices across five French-speaking Swiss cantons (Fribourg, Geneva, Jura, Valais, Vaud) with 136 employees serving more than 4,000 clients and managing over 1,100 audit mandates. Fidag is the #1 fiduciary in Romandie by number of audit mandates and ranks 7th in Switzerland; it is one of only three fiduciary firms in French-speaking Switzerland accredited by the Federal Audit Oversight Authority (FAOA) to audit listed companies, and holds ISO 9001 (1999) and ISO 14001 (2012) certifications. The firm is owned by its 29 active employee-shareholders, with the Board of Directors holding majority capital.

The firm's core offerings span four integrated service lines: (1) accounting (bookkeeping, payroll, year-end closing, consolidated accounts per Swiss GAAP FER and IFRS); (2) audit (statutory and limited audits of companies, pension funds, municipalities, and listed entities); (3) tax advisory (returns, restructuring, ruling applications, VAT, inheritance, served by a 12-person tax team including 6 certified tax experts); and (4) business consulting (formation, restructuring, succession, due diligence, company valuation via DCF and multiples, management controlling, IT audit per COBIT, SOX-aligned internal controls). Technology is operational rather than productized: Fidag implements accounting software (WinBiz) for clients, conducts IT audits per COBIT, and uses Microsoft Teams and Google Analytics for internal collaboration and marketing measurement; there is no proprietary AI, SaaS product, or API platform described.

FIDAG's revenue model is professional-services engagement-based, with no publicly disclosed pricing (consistent with the fiduciary industry norm). Go-to-market is sales-led, relying on direct in-office consultations across the regional network, referrals from professional networks and the GGI international alliance, industry events and seminars, and reputational signals (Statista/Bilanz/Le Temps rankings, ISO certifications). The firm has expanded historically by acquisition (Dino Venezia SA, Lausanne, 2016; 40% stake in Fidag Jura SA, Delémont, 2019; launch of Fidag Genève SA, 2020) and by internal promotion cadence (annual Deputy Director promotions in 2024 and 2025). Target segments are diversified and SME-weighted: small and medium enterprises (commerce, hospitality, tourism, construction, ski lifts, manufacturing), pension funds, public sector (municipalities and authorities), non-profits (associations, foundations, hospitals), liberal professions (doctors, lawyers, notaries), and high-net-worth individuals. All 29 shareholders are Fidag employees, creating an owner-operator alignment model typical of mature Swiss fiduciary partnerships.
