Sparxity
Sparse-native compute for AI: hardware and systems that compute only what matters
About Sparxity
Sparxity, formerly SpiNNcloud, is a Dresden-based TU Dresden spin-off building sparse-native computing systems for AI and HPC, from its own processors and boards to software and multi-rack systems. Its hardware activates compute only where a model needs it, aiming at faster, cheaper and more energy-efficient AI inference. The company reports three tape-outs, more than 70,000 chips produced, 12+ racks deployed and 30+ customers, including Sandia National Labs and the Jülich Supercomputing Centre.
