Multiverse Computing

Multiverse Computing is a San Sebastian, Spain-based quantum software company that develops algorithms for solving complex optimization and machine learning problems in finance, energy, and manufacturing using quantum and quantum-inspired computing techniques. The company's CompactifAI platform uses tensor network methods — mathematical approaches borrowed from quantum physics — to compress and accelerate large AI models, enabling LLM inference and training on less powerful hardware. Multiverse's finance applications include portfolio optimization, fraud detection, and risk assessment using quantum algorithms designed for NISQ (Noisy Intermediate-Scale Quantum) hardware. The company serves financial institutions, energy companies, and industrial manufacturers that have identified specific optimization problems where quantum approaches provide advantage. Founded in 2019, Multiverse raised over $27M from investors including Columbus Venture Partners, Quantonation, and the European Innovation Council. It competes with 1QBit, QC Ware, and Zapata Computing in the quantum software and applications market.
