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.
Ivan Zhao
Ivan Zhao is the co-founder and CEO of Notion, the all-in-one workspace platform used by over 100 million people worldwide. Born in Ürümqi, China, he studied cognitive science and fine arts at the University of British Columbia before nearly going bankrupt building Notion, retreating to Kyoto for eight months to rebuild the entire codebase from scratch. Today Notion is valued at $11 billion with $600 million in annual revenue, and Zhao still owns roughly 30% of it — an unusually large stake that reflects his insistence on building deliberately, keeping the team small, and refusing to let investors dictate the product's direction.
