German Startup Sparxity Secures €80Mn to Advance AI Computing Technology

The funding round was led by ICM HPQC Fund. Other investors included Lockheed Martin Ventures, GlobalFoundries, GS Futures, Cloudberry Ventures, TGFS and the EIC Fund.

The round also received investments from angel investors Richard Socher of Recursive Superintelligence and Nancy Xu of Moonhub, which was acquired by Salesforce. Existing investors Atlantic and Silicon Catalyst also continued to support the company.

“The next era of AI will be defined not just by how much computing power we can deliver, but by how intelligently and efficiently we use it,” says Sparxity co-founder and CEO Hector Gonzalez. “This financing is a powerful validation of our vision for sparse-native computing and the complementary positioning of our systems. With the backing of leading, strategic investors, we’re accelerating the transition from dense, energy-intensive architectures to heterogeneous datacenters with dedicated silicon for ultra-sparse workloads to unlock greater AI performance and lower costs.”

“Our work with PEER demonstrated the potential of dynamic sparsity, activating only a fraction of the compute across millions of fine-grained experts,” adds Xu Owen He, former Google DeepMind researcher and Sparxity strategic advisor. “Yet today’s hardware limits how far we can take these approaches. Co-designing AI models, distillation pipelines, and hardware around sparsity unlock a new level of computing efficiency.”

“Sparxity has a unique complementary positioning at the infrastructure stack. Its architecture is grounded in first principles, addressing the inevitable shift toward sparse activation and the structural limitations of conventional hardware,” says Matthew Gould of ICM HPQC Fund.

Founded in 2021, Sparxity develops computing technology for artificial intelligence (AI). Its systems are designed for large-scale data centres and supercomputers. The company has already deployed its technology across Europe and the United States.

Sparxity uses a method called sparse computing, which reduces unnecessary calculations and data movement. This helps computers process information more efficiently while using fewer resources.

The company says its technology has delivered strong results in selected workloads. These include solving certain computing problems up to 10 times faster, reducing energy use by 18 times in event-based machine learning and cutting the time needed for some optimisation tasks by 20 times.
