What Cairn Corporate Services does

Cairn Corporate Services (CAIRN CS) is a Marseille-based French accounting and financial services firm (cabinet d'expertise comptable) founded in 2013 by Marie-Pierre Bureau and Evelyne Isaia, both previously at SICIER, with Julien Dubout joining as a third partner in 2015. The firm specializes exclusively in serving real estate investment vehicles — OPCI, SIIC and SIIC subsidiaries, non-listed foncières, property developers (promotion immobilière), property traders (marchands de biens), and hotel funds — providing a five-module integrated service offering: accounting/tax/legal management, financial reporting, fund unit valuation (valorisateur de parts), cash management, and advisory services.

The firm's operational backbone is a set of proprietary automated reporting systems developed internally for client-specific needs, including OPCI-specific accounting modules that handle subscription/redemption management, estimation differences, and subscription commission tracking, as well as financial reporting engines that produce automated financial statements with per-property cost allocation. The team comprises 22 professionals including two experts-comptables and one diplômé d'expertise-comptable, with deep regulatory expertise in AMF-grade reporting, NAV publication, and French real estate tax (TVA, IS, liasse fiscale, droits d'enregistrement).

Cairn operates on a quote-based professional services pricing model with no public rates, generates revenue through ongoing retainer and project-based engagements, and acquires clients through direct B2B relationships, industry reputation, and referrals from enterprise customers. Its GTM is sales-led and targeted at real estate investment companies and asset managers; named enterprise clients include Swiss Life Asset Managers France (relationship since 2007), Scaprim, Cegereal (since 2018), Spirit REIM Services, BC France, and Matacapital. The firm is privately held by its three partners with no external institutional investment and operates from two Marseille offices.
