About
I'm passionate about making risk management clearer and fairer for everyone. Through my work at CatX and now Cactus, I build technology that helps the insurance and investment worlds understand complex risks in simple terms.
Our goal is practical: when everyone sees risk the same way, we can spread it efficiently across the economy, making communities more resilient to disasters.
