We collected these quotes from things they published elsewhere, and every quote links to where it was said. They have no account here and have not endorsed this site. Quotes are word for word; the short line under each one is our own restatement, not their wording. Their own site. Is this you? Claim it or ask us to remove it. Or tell us what is wrong here.

Six ideas Pieter Levels's claims keep coming back to. The grouping and the labels are ours; every quote under them is in Pieter Levels's own words.

  1. One person with cheap tools, AI and a server can build and run a business
  2. AI chat apps and big labs are absorbing apps and services, so building alone no longer sets anyone apart
  3. Heavy regulation and an anti-business culture hold Europe back while builders move elsewhere
  4. Doing new work means ignoring consensus, expecting haters, and holding opinions weakly
  5. Ultra-processed food and modern habits are behind many health problems
  6. Friendship and community take deliberate effort and matter as much as fitness for health

One person with cheap tools, AI and a server can build and run a business
