CI 33

What CI 33 does

CI 33 is a private French accounting and statutory audit firm (Expert-comptable et Commissariat aux comptes) founded in 1992 and headquartered in Bordeaux, with a second office in Arès serving the Arcachon Basin in Nouvelle-Aquitaine. The firm is led by two partners — Xavier LANNELUC (associated for 25 years) and Maxime HUERTA (partner since 2021) — and employs approximately 20 collaborators organized into four poles covering accounting-tax, payroll/social management, legal support, and administration.

The firm delivers a full-service professional offering: bookkeeping, tax declarations (VAT, IS, CFE), financial statements, payroll and social declarations, business creation support, legal secretariat, statutory and contractual audits, and business valuation. It supplements these services with two third-party digital tools — the Pennylane cloud accounting platform and the MEG by RCA cash flow/invoicing module — plus a suite of 16 in-house financial simulators for loans, investments, and payroll calculations. CI 33 holds the regulatory licenses required to perform statutory audits in France and is RGPD-compliant.

Commercially, CI 33 operates a sales-led, relationship-driven model targeting PME and TPE clients across five vertical specializations: liberal professions (notably medical/paramedical), real estate (SCI/LMNP), artisans and shop owners, hospitality and restaurants (HCR), and influencers/content creators — a niche it entered in 2019. Revenue is generated through recurring accounting, payroll, and tax mandates supplemented by project-based audit, valuation, and business creation fees, with bespoke pricing per client and a free initial consultation for business creation prospects. No external investors, parent company, or funding rounds are evidenced; the firm is owner-operated by its two partners.
