Alumni Q&A

How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?)
The two founders met in 2016 while working at BlackRock and lived together during the pandemic. They concluded that large established institutions were too slow to innovate in financial analytics, particularly with AI, and left their finance careers to start the company.
What is your long-term vision? If you truly succeed, what will be different about the world?
The founders note that most financial analytics was built in the 1990s on C++ running on CPUs, while the AI community has since adopted Python machine-learning tools running on GPUs, which they consider much faster in both development and run-time. Their goal is to rebuild financial analytics on this newer stack, spanning economic scenario simulation for banks and insurers to portfolio risk models for hedge funds, and to have the platform used across financial institutions.
