What OPTIMAL - Human Reinforced does

Optimal - Human Reinforced (legal entity Optimal Business Action S.A., trading as Optimal HR Group) is a privately held, founder-owned HR services firm founded in 2005 by Menelaos Kyriakopoulos and headquartered in Halandri, Athens, Greece. The company delivers bespoke human-capital services to corporate clients across the EMEA region, organized into seven service divisions: Talent Acquisition, Recruitment, HR Strategy & Talent Development, Workforce Management, Outplacement, Learning & Development, and Employer of Record (EOR) Services. It serves both large organizations and SMEs, with sector experience concentrated in FMCG, pharma, industrial, financial services, energy, hospitality, telecom, and retail. As of 2025 the firm operates with a team of approximately 40 professionals and celebrated its 20th anniversary.

This is a professional services business rather than a technology product company; it has no proprietary software platform, API, or mobile app, and its only disclosed technology footprint is standard website tooling (Google Analytics and Google reCAPTCHA). Its offering is anchored in a regulated EOR/temporary-staffing capability operating under Greek Temp & EOR Services License No. 19702/617/10.06.2029 and Greek Labor Law compliance (including the ERGANI II system), supplemented by ISO 9001, 27001, 14001, and 45001 certifications and GDPR compliance. Service delivery is reinforced by a portfolio of exclusive Greece/Cyprus partnerships — Gi Group (40+ countries), Tack TMI International (55+ countries, operating locally as sub-brand Tack TMI Greece), Career Star Group (outplacement), and Advanced People Strategies (HR strategy) — which extend international reach and methodology to a locally-licensed practice.

The business monetizes through professional-services engagements billed on project-based and retainer arrangements (consulting, talent acquisition, executive search, learning & development) and managed-services fees for EOR, where Optimal becomes the legal employer of a client's Greek-based workforce and administers payroll, statutory benefits, and compliance. Go-to-market is primarily sales-led via expert consultants engaging enterprise and mid-market clients directly, complemented by candidate-facing job portals and CV-submission pages that create two-sided marketplace dynamics, and by event participation and organic social/content marketing. Pricing is customized and quote-based; no rates are publicly disclosed and no revenue figure is reported.
