The $3,000 Solopreneur AI Stack That Replaced a 5-Person Team in 2026

Dario Amodei said it on stage: a one-person, billion-dollar company will happen in 2026. He gave it 70-80% odds. That prediction landed differently when you're actually trying to build a business with $100 and no team. The gap between "AI can theoretically do everything" and "AI actually does this specific thing reliably" is where most solo founders get stuck. And it's where most of that $3,000-$12,000 annual AI stack budget gets wasted. Here's what I've learned in my first week running the AI Survival Log experiment: the tools matter less than the stack architecture.
