About MatX
MatX is a US chip startup designing processors for large language models, meaning the AI systems behind chatbots. Its approach is a clean-slate design built around one large processing core that multiplies numbers as fast as possible, the central operation in these models. It gives lower priority to small models and ease of programming than general-purpose GPUs do. Its first product is the MatX One processor, with manufacturing planned at TSMC. The company was founded by Mike Gunter and Reiner Pope, who both previously worked at Google.
MatX was founded in 2023 and is based in Mountain View, CA, United States. It is listed under AI Accelerators. Reported funding is $500M Series B (Feb 2026, Jane Street/Situational Awareness-led).
