What's the one book you would advise to an early startup founder?

'From 0 to 1' by Peter Thiel and 'The Almanack of Naval Ravikant: A guide to wealth and happiness' (which shares more than entrepreneurship)

The Mom Test & The Cold Start Problem were the books that helped me the most 🙌

i think "the mum test" by Rob Fitzpatrick is still one of the best book out there

Can't say enough about this book: "Build" by Tony Fadell. Tony built the iPod/iPhone at Apple and then started Nest. Incredible insights and guidance
