About
Heptabase is a Taipei-based visual knowledge management platform that lets researchers, students, and knowledge workers organize complex information through a spatial whiteboard interface — placing notes as cards on infinite canvases, connecting related ideas visually, and enabling the kind of non-linear thinking that linear note-taking tools like Notion and Obsidian constrain. Founded in 2021 by CEO Alan Chan and backed by Y Combinator, Heptabase raised $2.2 million in funding, reached $1.2 million in revenue in 2024 with 30,000 active paid users, growing with an 8-person team.
