What SFBX does
SFBX is a French privacy technology company headquartered in Bordeaux (15 Place Canteloup, 33800) that provides AppConsent®, a Consent Management Platform (CMP) engineered for GDPR and e-privacy compliance across web and mobile digital properties. The platform is built on Chainsaw, SFBX's proprietary private blockchain designed for low-energy, immutable storage of consent records and all consent mutations (acceptance, refusal, withdrawal, and modifications), delivering proof of consent that the company positions as exceeding GDPR's minimum requirements. Founded in 2017 and operating as a privately held SAS under French law (registered capital €88,240; Chairman Alain Levy), SFBX serves a customer base of more than 13,000 websites and apps and processes over 1 billion consents per year.
The platform is distributed through a hybrid go-to-market model. Small and mid-sized businesses are acquired product-led via self-serve SaaS plans — Essential at €15/month (up to 40,000 monthly unique visitors, one domain) and Standard starting at €35/month (100,000 visitors, five domains) — with a 14-day free trial and Stripe-powered automated billing. Enterprise and premium accounts are sold via direct field sales with custom contracts and postpaid billing. A freemium "Xchange" tier exchanges free CMP access for non-intrusive consented device data, and an Xchange Solidaire variant partners with Ad4good to channel 50% of advertising margin to associations for solidarity-adopting publishers. SFBX earns supplemental revenue from data monetization, selling consented data sets to buyers via smart contracts for traceability use cases.
The platform is Google Certified CMP, supports Google Consent Mode v2 (GCMv2), integrates the IAB Transparency and Consent Framework, exposes REST APIs for CRM/DMP integration, and provides iOS and Android SDKs plus JavaScript/TAG scripts. SFBX is hosted on Google Cloud with data residency across France, Belgium, and the Netherlands, and the company maintains active involvement in GESTE and IAB industry associations for regulatory alignment. Named customers include Bouygues Télécom, Le Figaro, CCM Benchmark, and Solocal.
