What InterFast does
InterFast is a SaaS all-in-one management platform purpose-built for small and medium-sized building trade companies in France and adjacent French-speaking markets. Founded in 2021 by Hedi Marinier (a former HVAC entrepreneur) and Christopher Laszczuk (software engineer), the company is headquartered at Station F in Paris and operates as a bootstrapped, profitable SAS (RCS Paris 900 447 152). The platform consolidates quote generation, invoicing, CRM, client portal, planning, field interventions, GMAO maintenance, electronic signatures, document management, QR-code asset tracking, geolocation, and bank reconciliation into a single product, with a free tier and three paid plans (Solo €15/user/month, Pro €30, Business €45) sold per active user with no seat limits.
The technology stack comprises a NestJS/TypeScript backend, React web frontend, Flutter and React Native mobile apps (iOS and Android, offline-capable), PostgreSQL, and AWS infrastructure hosted in the EU. Domain-specific modules include Cerfa 15497 for refrigeration fluid compliance, Trackdechets waste tracking, Factur-X (Pennylane) and Peppol/Mercurius electronic invoicing integrations, and a BatiLégende podcast/ambassador content engine that drives top-of-funnel acquisition. The customer base spans 20,000+ building trade businesses across HVAC, plumbing, electrical, roofing, locksmithing, painting, landscaping, pest control, and multi-trade contractors, with named anchor customers in France and new geographic expansion into Belgium, Switzerland, and DOM-TOM.
The business model is freemium-led with PLG onboarding (7-day trial, no credit card) supported by an inside sales team for demos and an annual ambassador program of 16 trade professionals. Revenue comes predominantly from per-user SaaS subscriptions billed monthly or annually (25% discount), supplemented by free onboarding and migration services from legacy tools (EBP, Batigest, Vertuoza, Codial, Costructor). Distribution combines direct digital channels, content marketing (3.5M monthly content views, BatiLégende podcast with 120k+ cumulative listening hours), and the CAPEB federation partnership reaching 1.4M member artisans. The company has raised no external funding and remains founder-controlled.
