Building something people actually want is the hardest part of starting a company. Brian Chesky scaled Airbnb to a $100B company by obsessing over what users needed before anyone else saw the opportunity. most founders build for everyone and end up reaching no one. the ones who win go so deep on a specific problem that their first 100 users feel like the product was built just for them. that is the whole game. #BrianChesky #Airbnb #productmarket fit #startupadvice #founderadvice #buildinpublic #
