Multiverse Computing, a leader in quantum-inspired AI, has secured €189 million ($215 million) in a Series B funding round to scale its CompactifAI technology. This innovation compresses large language models (LLMs) by up to 95%, enabling faster, cost-efficient, and energy-saving AI deployment across industries.
Multiverse Computing raises $215M in Series B funding.
CompactifAI compresses LLMs by up to 95% with minimal accuracy loss.
Reduces inference costs by 50%-80% and speeds up processing 4x-12x.
Supports edge devices like phones, cars, and Raspberry Pi.
Backed by Bullhound Capital, HP Tech Ventures, Toshiba, and others.
Targets $106B AI inference market with energy-efficient AI.
Multiverse Computing’s CompactifAI uses quantum-inspired tensor networks to compress LLMs by up to 95% while maintaining accuracy. “The prevailing wisdom is that shrinking LLMs comes at a cost. Multiverse is changing that,” said Enrique Lizaso Olmos, Founder and CEO of Multiverse Computing. Unlike traditional methods like quantization and pruning, CompactifAI achieves only 2-3% precision loss, offering 4x-12x faster processing and 50%-80% lower inference costs.
CompactifAI’s compressed models run on cloud, private data centers, or edge devices like smartphones, cars, and Raspberry Pi. “For the first time in history, we are able to profile the inner workings of a neural network to eliminate billions of spurious correlations to truly optimize all sorts of AI models,” said Román Orús, Co-Founder and Chief Scientific Officer. This enables new use cases in healthcare, automotive, and telecommunications, making AI accessible in resource-constrained environments.
The €189 million Series B, led by Bullhound Capital with investors like HP Tech Ventures and Toshiba, will accelerate CompactifAI’s adoption. “Multiverse’s CompactifAI introduces material changes to AI processing that address the global need for greater efficiency in AI,” said Per Roman, Co-founder & Managing Partner at Bullhound Capital. The funding targets the $106 billion AI inference market, projected to reach $255 billion by 2030, positioning Multiverse as a key player.
With over 160 patents and 100 global customers, including Iberdrola and Bosch, Multiverse is recognized as a top AI innovator by CB Insights and DigitalEurope. “The Multiverse team has solved a deeply complex problem with sweeping implications,” said Damien Henault, Managing Director at Forgepoint Capital International. CompactifAI’s efficiency improvements democratize AI, enabling smaller organizations to leverage powerful models.
Multiverse Computing’s technology addresses the energy and cost challenges of LLMs, revolutionizing AI deployment. By enabling scalable, efficient, and greener AI, the company is poised to transform industries, supported by a robust investor syndicate and a vision for global AI accessibility.
