IMfinity

IMfinity is a French staffing and talent solutions group founded in 2017 by Arnaud Desclèves and headquartered in Paris. The firm specializes in high-impact support for corporate functions through three core offerings: Management de Transition (interim leadership), Temps Partagé (fractional experts), and Recrutement (permanent hires on CDD/CDI). Its legal practice, IMfinity Juridique, is structured like an ESN to deliver assistance technique, turnkey services, and advisory to corporate legal departments, and the group also covers HR, finance, sales, marketing, communications, and IT roles. IMfinity’s hallmark is operational excellence combined with speed and flexibility: clients can engage experts full-time, part-time, or on a shared basis, on site or remotely, with rapid deployment to address replacement needs, peak workloads, transformation programs, post-merger integration, or crisis situations. A rigorous methodology underpins every mandate—“Attirer, Vérifier, Greffer”—supported by stringent technical, soft-skill, and English assessments, and enhanced by modern tools that power what the firm calls Augmented Interim Management. IMfinity’s Academy strengthens the soft skills and leadership capabilities of its community of managers to ensure consistent delivery standards. The group operates with transparent, budgetable pricing: fixed daily rates (TJM) for external interventions and retainer or success-based fees for permanent recruitment. Clients range from CAC 40 companies to ETIs and SMEs across all sectors, with references including Bouygues Telecom, TotalEnergies, ENGIE, Safran, and Thales. Direct access to an associate-level expert ensures precise briefing, selection, onboarding, and ongoing mission oversight, while dedicated sales administration teams interface seamlessly with procurement, HR, and AP functions. Strong roots in the “métiers de la Norme” (legal, compliance, tax, data privacy) are complemented by broader corporate and technology coverage, enabling IMfinity to match specialist talent to complex contexts. With ambitious digital projects and an international outlook, the group aims to be the partner of choice for the most demanding staffing challenges.
