This is Marc Lou, who makes $77K/month as a solopreneur. No agent swarms. No background automations. No productivity stack worth bragging about. He uses just one code editor, one AI chat on the right side, single-threaded. He talks, it builds, he ships, he moves on. His take: the only KPI that matters in the AI era hasn’t changed. It’s still the number of things you ship. Out of 35 startups, 30 flopped. The 5% that hit paid for everything. So he just keeps rolling the dice.
