“I think the billion-dollar one-person company is a lie. I think the companies that actually do reach a billion people and billions of valuations — they need more than one person. You need a team, you need a brand, you need retention. AI can improve the value the product gives to users, and then and only then can it really create massive amounts of value.”

Build the team early — the billion-person company myth of solo plus AI is a lie

Schlenker opened his App Growth Annual Tokyo talk with a direct refutation of the popular 'vibe code to $30M solo' narrative. His argument: every massively scaled consumer app — the ones with hundreds of millions of users and billion-dollar valuations — was built by a team with complementary skills, a brand with soul, and retention that compounds over years. AI accelerates product development but cannot substitute for the human decisions that create brand, culture, and trust with users. Opal hit $10M ARR with 11 people; scale beyond that required growing the team further.
