The AI-Powered Startup Stack

The Real Talk

AI tools don't replace thinking. They replace execution time. You still need:

- Product vision — AI can't tell you what to build - Customer understanding — Talk to users, don't just generate personas - Quality control — AI output needs human editing and review - Brand taste — Generic AI content is detectable and forgettable

The startups winning with AI are the ones using it as leverage, not as autopilot.
