Prior to starting Persee Ventures, we built self-driving cars, created trading algorithms, and ran technology teams. As we grew in our professional experiences, we found ourselves applying common technology processes and data techniques across different problems.

Through it all, we learned our role is simple -- we support companies building better widgets. We are full-stack developers, data architects, data scientists, and financial engineers working side-by-side with teams to build the next generation of financial technology solutions.

Our Core Beliefs

We love solving hard problems

Whether it's automating stock selection or recommending vacation destinations, we enjoy working with teams to find solutions to their toughest problems.

We hate inefficiency

If it can be automated, we will do it. We're thrilled when we shave hours and sometimes days off of clients' workflows using our systems.

Your success is our success

We're fully vested in the success of each one of our clients. Having launched new products at startups and large institutions, we understand building for the future while keeping existing customers and investors happy.
