The fellowship paired weekly progress with build-and-demo sprints. Fellows tried ideas in the open, worked with each other, and tested products with the people who might use them.

The final demos showed six open-source builds across character-led learning, professional certification practice, student-built business tools, AI search discovery, analyst simulations, and middle-school math games.

Motivated by a better learning experience for his neurodivergent brother, Jasjeev built PersonaLM. In 30 days it reached more than five million organic views, a 1,000-person waitlist, and its first beta pilot.

Xiangan built Whetstone for professional exams, including Claude Code Architect and CISSP. He ran two paid Claude Code Architect pilots and a CISSP pilot with Boston University students.

Barbara, an Acton Academy school owner, built Strata Mundo to adapt math games to a learner’s understanding. She piloted it at her school and ran a workshop where students designed their own games.

“We literally 10x’d our customers and made a functional product.
The personalized feedback and coaching was extremely helpful in navigating new process of making a product zero to one.”
“I joined the fellowship to see how AI can change education. Through this fellowship, I became a builder and worked on something unique for learners. I never expected that to happen. I was able to grow in a lot of practical skills and pilot new projects with my learners.”
“The fellowship reframed how I think about edtech, not only the technology, but connecting with learners and instructors and getting a product into the world. The best part was being around other like-minded people.”
