Grupo Constant

What Grupo Constant does

Grupo Constant Servicios Empresariales, S.L.U. is a Barcelona-headquartered Spanish HR consulting firm founded in 1987 that provides temporary employment (ETT), outsourcing, and facility services through six specialized sub-brands. The group operates across logistics and industrial staffing (Gesgrup), hospitality (Staff Hotel), field marketing and commercial outsourcing (Prosales), professional cleaning and ancillary facility services (Weldon), landscaping (Verdalis), and core temporary employment (Personal 7). Its proprietary technology layer consists of in-house-developed web-based systems for candidate evaluation, selection, and hiring, maintained by an internal IT department, with 24/7 availability for emergency placements. The business model is primarily transaction-fee based on temporary placements (with 19,614 contracts executed by Personal 7 in a recent year and 578 clients served by that sub-brand alone) and managed-services contracts for outsourcing and facility engagements priced on unit-based and productivity-based structures that convert client fixed labor costs into variable costs.

The company runs a national distribution network of 20+ branch offices covering mainland Spain plus the Balearic and Canary Islands, employs 399 corporate staff, and places approximately 23,298 workers at client sites annually, totaling 23,697 people contracted per year across 644 enterprise and mid-market clients. Disclosed annual billing is €154 million, with subsidiaries Weldon operating its own 20 branches and 700+ employees and Gesgrup averaging 2,000 employees. Grupo Constant holds ISO 9001 quality management certification, ISO 14001 environmental certification (limited to Barcelona gardening activity), GDPR-compliant data processing infrastructure, and an SGI seal against workplace harassment, positioning it for regulated enterprise and public-sector procurement. The firm is privately held as a Sociedad Limitada Unipersonal with no disclosed parent company, private equity backing, or public listing, and operates exclusively within Spain.
