GalexC Gilman A. Callsen

I build startups that use real-world data to solve real-world problems. I'm passionate about accelerating the adoption of genuine climate solutions. Right now, I run Rho Impact, where we're making the world's fastest impact modeling software. Before that, I built real-time race strategy software, helped develop the world's first open-access climate impact forecasting tool, and co-founded two other startups in advanced materials.
