I'm Matt Shumer — founder & CEO at OthersideAI (HyperWrite). I build and invest in AI products, ship fast, and share what I learn with a large audience.
Lately: pushing GPT‑5 to its limits, collaborating on AutoRL with OpenPipe (acquired by CoreWeave), and helping early teams go from zero → launch.
I also have a slight obsession with sushi and food in general. Most of my free time is spent cooking and eating.
