Multiverse Computing just raised a massive €189 million ($215M) Series B on its model-shrinking tech, CompactifAI.
This compression tech cuts LLM sizes up to 95% with no hit to performance, the startup said. Smaller, faster LLMs ready for AWS or on-premise.
Models include compressed versions of Llama 4 Scout, Llama 3.3 70B, Llama 3.1 8B, and Mistral Small 3.1. DeepSeek R1 support is coming. OpenAI models? Not supported. 
Their “slim” models run 4x to 12x faster. That drops inference costs 50%-80%. Example: Llama 4 Scout Slim costs 10¢ per million tokens on AWS vs. 14¢ for original.
Multiverse says some models are tiny and energy-efficient enough for PCs, phones, cars, drones, even Raspberry Pi.
CTO Román Orús, a professor known for tensor network research, co-founded the company. His work simulates quantum computing on classical systems – key to their compression tech. CEO Enrique Lizaso Olmos brings math creds and banking exec experience.
Bullhound Capital led the round. Investors include HP Tech Ventures, SETT, Forgepoint, CDP Venture Capital, Santander Climate VC, Toshiba, and Capital Riesgo de Euskadi – Grupo SPR.
Multiverse holds 160 patents and counts 100 clients like Iberdrola, Bosch, and Bank of Canada. Total funding now about $250M.
CompactifAI is a quantum-computing inspired compression technology that is capable of reducing the size of LLMs by up to 95% without impacting model performance, the company said.
Its “slim” models, as the company calls them, are available via Amazon Web Services, or can be licensed for on-premise usage. The company says its models are 4x to 12x faster than comparable not-compressed versions, which translates to a 50% to 80% reduction in inference costs. For instance, Multiverse says its Lama 4 Scout Slim costs 10 cents per million tokens on AWS compared to Lama 4 Scout’s 14 cents.
Multiverse claims some of its models can be made so small and energy efficient that they can be run on PCs, phones, cars, drones, and even the DIY-enthusiast’s favorite tiny PC, Raspberry PI.
Multiverse says it has 160 patents and 100 customers globally, including Iberdrola, Bosch and the Bank of Canada. With this funding, it has raised about $250M to date.
