JME Ventures originated as the venture arm of Acciona chairman's family foundation before spinning out to manage independent funds, giving it deeper corporate and infrastructure roots than typical Spanish VCs, and has become one of Spain's largest early-stage platforms by managing over €120-150m across four funds while maintaining an unusually narrow focus on Spanish-founded startups. The fund operates a bifurcated investment process where sub-€300k checks can be completed in under a month with no formal due diligence, while larger tickets above €500k trigger full approval processes, and explicitly rejects formal ESG screens in favor of backing technology that disrupts markets and raises productivity.
