Multiverse Computing is Europe's largest quantum software company. It commercializes quantum-inspired tensor-network algorithms — mathematics developed for simulating quantum systems — for finance, energy and manufacturing. Its breakout product, CompactifAI, uses those techniques to compress large language models by up to 95% with minimal accuracy loss, putting it at the intersection of the quantum and AI markets.
The company raised a $215M round in June 2025 led by Bullhound Capital, then announced a Series C in July 2026 targeting up to $570M (€500M) at a $1.7B (€1.5B) pre-money valuation. The round may remain open and is expected to bring total funding to $800M.

What is CompactifAI?
A quantum-inspired compression technology that shrinks large language models by up to ~95% using tensor networks, cutting AI inference costs. It is Multiverse's main commercial product and the driver of its 2025–26 fundraising.
Is Multiverse a real quantum company if it runs on classical hardware?
Its algorithms are "quantum-inspired" — tensor-network math from quantum physics running on classical hardware today, with quantum backends as hardware matures. Investors treat it as a quantum-software leader.
