STS

What STS does

STS - Social Transport Solutions is a privately held French SAS headquartered in Lyon that has operated since 1999, building a 100% web-based Human Resources Information System (SIRH) dedicated exclusively to the French road transport (TRM) sector. Its platform unifies time and activity management (GTA), a proprietary transport-specific payroll engine (co-developed with Yeap and integrated without outsourcing), social charge optimization, regulatory monitoring, legal support (URSSAF/DREAL/DREETS inspections), and reporting into a single collaborative portal. Connected hardware devices — STS Mobilité PL (Bluetooth driver-card reader for heavy goods vehicles) and STS Mobilité VL (web application for light vehicles) — feed automated data into the platform, and a recently introduced Stisy AI chatbot (November 2025) adds conversational analytics and risk anticipation.

The company serves a tiered customer base: 1,000+ very small transport enterprises (TPE) on a 699€/year subscription, 400+ small-medium enterprises (PME), and 25+ grands comptes including logistics names such as Geodis, Jacky Perrenot, Transports Bert, Groupe Deret, and RAS Interim. Across 2,500+ active clients the platform processes 350,000 legal files and manages 80,000+ employees monthly. Revenue combines recurring SaaS subscriptions, hardware device sales, and a distinctive "fournisseur-crééditeur" consulting model for social optimization in which STS bills only on realized savings (up to 7% of social charges). A new talent management module, co-developed with Empowill (launched December 2025), extends coverage into employee lifecycle management.

Distribution is sales-led via a nationwide network of dedicated transport-HR expert interlocutors, supplemented by flagship presence at Solutrans (Lyon Eurexpo), webinars on regulatory topics, SEO/content marketing, and a 24/7 self-service client portal. The company holds GDPR compliance, is hosted on OVH infrastructure, and reports a 97% client satisfaction rate with no disclosed external institutional funding.
