Banyan Software is pleased to announce the acquisition of M3 Informática (M3), a Madrid-based software company founded in 1990 to solve a problem that commercial HR platforms were never built to handle: payroll and workforce management for the Spanish public sector.
M3’s founders spent their careers inside the Spanish healthcare system before building SAINT, a platform purpose-built for the regulatory and workforce complexity of public institutions. SAINT handles what generic HR systems can’t: the position-based structures, compliance requirements, and payroll rules that govern how Spanish public sector organizations actually operate. Over 35 years, M3 grew from primary care to hospitals to regional health systems, and has never lost a full client to a competitor.
About M3 Informática. Founded in 1990 and headquartered in Madrid, M3 Informática develops SAINT, a mission-critical HR and payroll platform for the Spanish Public Administration. SAINT manages position-based workforce structures across regional health ministries, provincial governments, and municipalities, covering payroll calculation, shift management, position management, and employee portals. M3 serves clients across all three levels of Spanish government, with a primary focus on public healthcare. For more information, visit m3informatica.com
