“If you can build a product that is so good, people spontaneously tell their friends about it, you have done 80% of the work that you need to be a really successful startup.”
Altman: An unexplainable product signals unclear thinking or tiny market demand
“If you can't explain in a few words what you do, and if people don't, if at least some people don't say, oh, that's pretty interesting, that's usually a mistake. It's usually a sign of unclear thinking or a need that is not big enough.”
Altman: Most important startups start in rapidly growing small markets

Altman: Real trends feature obsessive early usage; fake trends lack engagement
“Real trends are ones where a new technology platform comes along, and the early adopters use it obsessively and tell their friends how much they love it. A fake trend is one where people may buy the product but don't use it, or at least not enough.”
Altman: Virtual reality is a fake trend because buyers rarely use headsets
“A fake trend, or at least a fake trend as of, ah, August, 2018, I would say is VR. I do believe VR will be big someday, but today most people that I know, ah, that own a VR headset use it never or very rarely.”
Altman: Startups need an evangelical founder to recruit and succeed wildly

Altman: Startups need a few prolific idea generators, but not too many

Altman: Early Startups Win by Moving Fast with Incomplete Data
“Startups, especially in their early days often win by moving very quickly. You never get as much data as you'd like. You never have as much time to deliberate as you'd like. And you want people who will, are willing to act with much less data than they'd like …”
Altman: Inexperience leads startups to accomplish seemingly impossible things
“We have seen many of our startups do incredible things because no one told them it was hard, or no one told them they can't do it.”
