Multiverse Computing, the San Sebastián-based AI compression startup, has announced a €500 million ($570 million) Series C funding round at a €1.5 billion ($1.7 billion) pre-money valuation—a 5x step-up from its Series B. The round was co-led by Forgepoint Capital International, BNP Paribas Solar Impulse Venture Fund, and Bullhound Capital, with participation from HP Inc., Orange Ventures, Santander Alternative Investments, Tikehau Capital, Scania Invest, NAventures, Qatar Development Bank, Spain's SETT sovereign fund, and others.
Multiverse's core technology, CompactifAI, applies tensor networks (a mathematical framework from quantum physics) to compress large language models by 80–95% with minimal accuracy loss. The compressed models run faster, consume less energy, and can be deployed on edge devices, private data centers, or sovereign cloud without reliance on hyperscalers. Since closing its Series B in June 2025, Multiverse has grown annualized revenue more than 10x, with 96x year-over-year sales growth in Q1 2026—positioning it among Europe's fastest-growing AI labs and infrastructure businesses.
Customers span Allianz, Bank of Canada, Bosch, Iberdrola, PwC, Telefónica, and defense/aerospace sectors. The funding will expand Multiverse's model library, scale sovereign AI infrastructure, and establish regional presence in East Asia, Southeast Asia, the Middle East, Canada, and the U.S. For practitioners, Multiverse represents a European bet on efficient AI and AI on the edge—technologies that let operators run inference without hypergiant dependency.
