MatX Raises $100+ Million Series A for High Throughput LLM Chips

March 12, 2025

Sometimes a startup makes a lot of public noise as it develops. And sometimes it just works away, popping its head up every once in a while to announce a meaningful milestone. MatX is the latter. Founded by two ex-Google Tensor Flow engineers, they’ve been quietly building specialized LLM chips optimized for a world being changed by AI. And while they tend to not speak at conferences, or write a Substack, or, well, say much of anything beyond their website, they did share a bit of good news this week, namely a $100+ Million Series A led by Spark Capital.

MatX is now fully capitalized to bring their systems to market with an amazing, highly technical team of 50+ people! And of course if you are passionate about building the best chips for LLMs, well, they’re hiring.
