What STA Portage does
STA Portage operates in the French market under the OpenWork brand (rebranded in 2024 from the legacy STA Portage name) as a portage salarial — or umbrella employment — provider. The company serves independent professionals, primarily IT consultants, corporate trainers, management consultants, and interim transition managers, by converting their freelance turnover into formal employment income. OpenWork invoices end-clients on the consultant's behalf and remits a salary to the consultant, providing employee status (CDI/CDD contracts), social protections including unemployment insurance, a company-negotiated health insurance plan, retirement contributions, and payslips that enable access to credit and rental housing.
The core platform is a proprietary web and mobile application that handles the full operational lifecycle: remote identity verification, electronic contract signing, monthly CRA (timesheet) declaration, photo-based expense submission, client invoice tracking, and payslip access. Onboarding completes in under 24 hours entirely online. A salary simulation tool and resignation letter generator sit at the top of the acquisition funnel, supported by SEO content, the OpenLive webinar series, and a cooptation (referral) program.
OpenWork monetizes through a single flat 5% management fee on each consultant's pre-tax turnover (chiffre d'affaires HT), with no entry or exit fees — a structure marketed under a 'Zéro Frais Cachés' (Zero Hidden Fees) certification. Distribution is entirely digital across France, with a team of dedicated business developers providing human support for each consultant. The company reports 50,000+ consultants served over 16 years, 1,500+ new consultants per month, and end-client engagements with major French enterprises including Orange, GRDF, RATP, Adeo, and Samsung. ESG credentials include Ecovadis Gold, Label Lucie 26000, SBTi membership, Label RFAR, and Label Numérique Responsable, and customer satisfaction is documented through Google (4.6/5 on 143 reviews) and Trustpilot (4.8/5 on 394 reviews).
