Martin Schneider
Martin Schneider is the co-founder and CEO of RemNote, the all-in-one note-taking and spaced-repetition app he started coding as an MIT computer science student in 2017 to fix his own habit of forgetting everything he learned a semester later. What began as a private side project he used alone for three years grew into a learning platform with over a million users, backed by a $2.8M seed round from General Catalyst, 468 Capital, Soma Capital and Dorm Room Fund. He blends learning science, neuroscience and software to chase a single idea: that you should be able to learn something once and remember it forever.
Andrew Mao
Andrew Mao is the co-founder and CEO of Parsnip, an AI-powered learning app often called 'Duolingo for cooking' that helps novices build real confidence in the kitchen. A Harvard computer-science PhD and former computational social scientist, he ran the longest iterated prisoner's dilemma experiment ever conducted, built ML systems at neural-interface startup CTRL-labs (acquired by Facebook), and now applies the science of how people learn to the very human problem of figuring out what's for dinner.
Michael Xing
Michael Xing is the co-founder and CEO of Pingo AI (YC S25), a language-learning app that builds fluency by letting people talk with an AI tutor in real-life conversations. The idea grew out of weekly Chinese practice sessions with his freshman-year college roommate Morrie Schonfeld. After launching in January 2025, Pingo scaled from zero to hundreds of thousands of users and millions in ARR in under a year, becoming one of Y Combinator's fastest-growing consumer companies and a Google Play Best of 2025 winner. Before Pingo, Xing spent roughly three years at AI startups and built a Chrome extension with 150,000+ downloads.
Tim Novikoff
Tim Novikoff is the founder and CEO of Super Teacher, an AI tutoring app for elementary students that has reached roughly 20,000 families and public schools in New York, New Jersey, and Hawaii. A former NYC math teacher with a PhD in applied mathematics from Cornell, he co-authored a PNAS paper on the math of spaced repetition, built and sold the video-editing startup Fly Labs to Google in 2015, then worked on Google Photos and ran Google Colab before returning to education. As a kid he voiced Jeffy on MTV's animated series Daria.
Nhon Ma
Nhon Ma is the CEO and co-founder of Numerade, a Los Angeles-based education technology company building AI-powered STEM tutoring at scale. The son of Vietnamese refugees who grew up in south-central LA, he turned a full-scholarship private-school education and a two-tour stint at Google into a mission to close the educational opportunity gap. Numerade hosts one of the largest STEM video libraries online and an AI tutor named Ace, and raised a $26M Series A at a roughly $100M valuation.
