When starting a cat modeling company, one has to make choices for platform, science, products, and collaborations. Following the 10-year journey of KatRisk we will illustrate the development of global flood maps to probabilistic models including the development of our own financial model and SpatialKat platform. This led to the adoption of our products by more than 60 customers globally and a product offering from flood, storm surge, wind models into severe convective storm and wildfire. Key scientific and technical areas such as best simulation methodology, climate variability and change, deployed vs. hosted vs. API offerings, platform performance and opening up your own ecosystem of collaborators are illustrated as we enter the second decade of our development.
