A Think School conversation with Nir Eyal, author of Hooked, on why consumer startups with good products fail and how to build products people come back to using the Hook model (trigger, action, variable reward, investment). PARTIAL COVERAGE: the episode runs about 69 minutes and the available caption text is cut off, so this summary covers the first part, including the Fitbod case study, and not the final section. Examples and figures are the speakers' own claims and are unverified. This is a summary of Eyal's views, not advice.
