About

Ben and Jacob met in Calculus class in 10th grade, and tried founding a startup in high school — it didn’t go anywhere. During high school, Ben lead the frontend team for the World Health Organization’s COVID-19 App Team. After high school, Jacob went to Apple and Ben went to college. When there was an opening on his team, Jacob had Ben apply, and Ben left UChicago to go work at Apple. They spent about 2 years at Apple as Senior Engineers in the Conversational Engineering Department, before leaving to found Freestyle. Freestyle is directly inspired by what they saw as their failures of the tech they worked with at Apple.

Apple

I learned to code in elementary school. In high school I served as a code owner and technical lead for the World Health Organization COVID-19 App Collective Team. I did a year of college, then took a job as a consultant for Apple. In 3 months I became a senior. I left Apple to found Freestyle.

Jacob ZwangFounder/CTO
Apple

I dropped out of college and became an Apple senior full-stack engineer in Conversational Engineering at 19. During the year and a half I worked there, I delivered multiple projects to production at scale. I love building products that inspire and delight customers, but I'm frequently frustrated by poor back-end developer tools. My co-founder and I are building a new cloud and backend workflow so that we and others can build exceptional software in a fraction of the time.

A fundamental shift in how we approach web development

Freestyle lets developers write both frontend and backend entirely in TypeScript, removing context switching between languages and eliminating separate data stores and APIs. The launch describes deploying with a single command, npx freestyle deploy, and using @cloudstate to mark data, targeting organizations seeking a unified TypeScript–driven web development workflow.
