Multiverse Computing, a global innovator in quantum-inspired AI model compression, announced a €189 million ($215 million) investment round to further develop their CompactifAI – compression tech capable of reducing LLMs by up to 95%, while maintaining model performance. This San Sebastian-based company is a member of EIC Scaling Club’s Next-Gen Computing market group.
The investment will accelerate widespread adoption to address the massive costs prohibiting the rollout of LLMs, revolutionising the $106 billion AI inference market. The Series B round is led by Bullhound Capital with the support of HP Tech Ventures, SETT, Forgepoint Capital International, CDP Venture Capital, Santander Climate VC, Quantonation, Toshiba and Capital Riesgo de Euskadi – Grupo SPRI.
Solving tomorrow's LLM problems
LLMs typically run on specialized, cloud-based infrastructure that drives up data center costs. Traditional compression techniques—quantization and pruning—aim to address these challenges, but their resulting models significantly underperform original LLMs.
With the development of CompactifAI, Multiverse discovered a new approach. CompactifAI models are highly-compressed versions of leading open source LLMs that retain original accuracy, are 4x-12x faster and yield a 50%-80% reduction in inference costs. These compressed, affordable, energy-efficient models can run on the cloud, on private data centres or—in the case of ultra-compressed LLMs—directly on devices such as PCs, phones, cars, and drones.
Enrique Lizaso Olmos, Founder and CEO of Multiverse Computing, said:
“The prevailing wisdom is that shrinking LLMs comes at a cost. Multiverse is changing that. What started as a breakthrough in model compression quickly proved transformative – unlocking new efficiencies in AI deployment and earning rapid adoption for its ability to radically reduce the hardware requirements for running AI models. With a unique syndicate of expert and strategic global investors on board and Bullhound Capital as lead investor, we can now further advance our laser-focused delivery of compressed AI models that offer outstanding performance with minimal infrastructure.”
