We’re a super high growth health-tech startup building mobile apps that can change people’s behaviour. Our flagship app, Quit Genius, is a new way to quit smoking that delivers highly personalised therapy at scale. We’ve won design awards from Apple, already helped tens of thousands of people quit smoking and scaled a platform to a million users. We’ve raised funding from Y Combinator, Merck & Co and Village Global (backed by Jeff Bezos, Mark Zuckerberg and Bill Gates).
