Testing an idea used to cost me a day of hand-coding. Now it's 5 min to prompt, 30 to make tea. That's why I rewrote the book: when building is free, building the wrong thing is the only real cost. kromatic.com/download/the-re…

Talking to 200 customers isn't about 200 answers. It's about finding the 3 questions worth asking deeply. kromatic.com/real-startup-bo…

If my experiment only runs on AI-generated responses, I haven't talked to a customer yet. kromatic.com/real-startup-bo…

AI lowered the cost of building. Not the cost of building the wrong thing. kromatic.com/real-startup-bo…

Before I prototype an idea, I decide what result would make me delete it. If I can't answer that, I'm not running an experiment. kromatic.com/real-startup-bo…

If I can't bring myself to delete the code, I skipped the experiment and started building a product. kromatic.com/real-startup-bo…

AI lets me sketch a working product in hours. The hard part isn't building it — it's deleting it when the experiment ends. kromatic.com/real-startup-bo…

The most valuable output of running AI interviews at scale isn't the answers — it's knowing which questions are worth asking a human next. kromatic.com/real-startup-bo…

A bad AI interview prompt, run at scale, just produces confident noise. The discipline is in the question, not the volume. kromatic.com/real-startup-bo…

Speed only matters if you're headed somewhere real. AI helps me move faster — it doesn't tell me if the destination exists. kromatic.com/real-startup-bo…

A demo that works is not evidence that customers will buy. It's evidence that the demo works. kromatic.com/real-startup-bo…

The real AI risk isn't wrong answers. It's confidently wrong ones. kromatic.com/real-startup-bo…

If I wouldn't trust a junior researcher to improvise follow-up questions, I don't trust AI to either. I design the prompts before I run the interviews. kromatic.com/real-startup-bo…

When I can interview dozens of people at once with AI, the bottleneck shifts — it's no longer recruiting. It's knowing what to ask. kromatic.com/real-startup-bo…

Running 200 AI interviews isn't about 200 answers. It's about finding the short list of questions worth asking a human next. kromatic.com/real-startup-bo…

If I can't delete the code when the experiment ends, I probably stopped treating it as an experiment. kromatic.com/real-startup-bo…

AI lets me sketch a working prototype in hours. The hard part isn't building it — it's deleting it once I have my answer. kromatic.com/real-startup-bo…

AI-generated customer personas feel like insight. They're actually a shortcut past the customers. kromatic.com/real-startup-bo…

The real danger of AI in early-stage research isn't bad output — it's plausible output that replaces the conversation you needed to have. kromatic.com/real-startup-bo…

Most founders get bad data because they ran the wrong experiment for the question they had. AI runs it 10x faster — it can't tell you which question to ask. New RSB 2nd-ed teaser: kromatic.com/blog/rsb-teaser…

Every method in The Real Startup Book now has a copy-paste AI prompt. Work through it with Claude, ChatGPT, Gemini, or Codex — paste it, give your context, let it help design the experiment. kromatic.com/mcp?utm_campaig…
