TECNALIA is a Spain-based technology-transfer and corporate venture platform that backs and builds early-stage deeptech startups and partly owned companies. Based in Donostia-San Sebastián, it focuses on Spain and targets research-backed technologies across energy transition, industrial technology, smart manufacturing, mobility, health, food, circular economy and related software and AI applications. It is most relevant for founders seeking strategic venture support, applied R&D access and sector expertise rather than a conventional financial VC.
