Seresco

What Seresco does

Seresco is a Spanish ICT company founded in 1969 and headquartered in Oviedo, Asturias, listed on BME Growth, Spain's SME growth market. The company operates across seven solution areas: people management (anchored by its proprietary Milena payroll and HR platform, processing over 5 million payrolls annually), business management (Sage ERP, KUNEON, NEODOC), IT infrastructure, risk management and cybersecurity (with SOC, CSIRT, and GRC services), territory management (cartography, cadastre, MAPSTORM), software development, and service desk support. It also runs R&D projects in agritech, including the SEMANTIS data space (with CTIC RuralTech, built on Gaia-X standards), MAPA and MAPPLE drone-based crop monitoring with AI, and FabaTrap computer-vision pest detection. Seresco serves more than 3,000 clients across 25 countries, with a professional team of more than 1,200 spanning Spain, Portugal, Peru, and Colombia.

The company monetizes through three primary streams: managed BPO services (payroll outsourcing and HR administration under multi-year contracts), software subscriptions and licenses (Milena, MAPSTORM, and add-on modules), and professional services (IT consulting, cybersecurity, and digital transformation projects). Go-to-market is enterprise field sales targeting large companies and public administrations, supplemented by channel partnerships through acquired subsidiaries in Portugal and Latin America. Pricing is custom and not publicly disclosed, structured as multi-year enterprise contracts scoped to client size, employee count, and complexity.

Strategically, Seresco has pursued Iberian consolidation through acquisitions (76.87% of Portugal's ELO-SI in February 2023 for €1.4 million; F5IT in March 2025 for €2.5 million) while investing in EU-funded agritech innovation. FY2025 results showed revenue of €56.3 million (a 5% year-over-year increase) with an adjusted EBITDA margin of 17% (€10 million) and a committed project portfolio of €125 million over the next three years. The company holds ISO 9001, 14001, 27001, 33000, and 45001 certifications plus ISAE 3402 Type 2 reporting on Milena, reinforcing its positioning with regulated public-sector buyers.
