For US founders building with AI

How to Validate an AI Startup Idea (Without Wasting Months)

Most US founders waste 3-6 months building AI apps no one wants. Idea Bob scores your idea across 9 weighted dimensions in under 60 seconds, using live market data, competitor analysis, and the same pressure-test questions Y Combinator partners ask in interviews.

  • Score 9 dimensions: Market Demand, Problem Intensity, Revenue Potential, Moat, and 5 more
  • Live competitor scan via Firecrawl, no manual research
  • Paul Graham-style pressure test before you write a single line of code
  • Free to start, USD pricing, built for the US indie hacker / AI builder market

Why most AI startup ideas fail validation

The 2024-2026 AI gold rush created a generation of founders shipping LLM wrappers, RAG apps, and agent products with no validation. The result: thousands of dead Lovable/Cursor/Bolt projects with zero paying users.

The pattern is always the same: the founder fell in love with the technology before testing whether anyone would pay for the outcome. Idea Bob flips that. You describe the idea, the AI scores it against 9 weighted dimensions, and you get a clear BUILD NOW, REFINE, or KILL recommendation in under 60 seconds.

The 9 scoring dimensions explained

Each dimension is scored 0-10 by Google Gemini with grounded reasoning, then weighted into a single 0-100 Opportunity Score. The weights are tuned for AI/SaaS products specifically: Market Demand and Problem Intensity carry the most weight, while Tech Feasibility carries less because most modern AI ideas are technically buildable.

The dimensions: Market Demand, Problem Intensity, Revenue Potential, Competitive Moat, Tech Feasibility, Time to MVP, Customer Acquisition, Defensibility, and Founder Fit. You see the breakdown on a radar chart and can drill into the AI reasoning behind each score.

What happens after the score

A score is just the start. Idea Bob then runs a Paul Graham pressure test, generates Mom Test interview scripts you can take to real customers, scrapes competitors with Firecrawl, builds a market research report with TAM / SAM / SOM, and drafts a startup strategy with the Fastest Way to Validate, an MVP blueprint, and a monetization plan.

For US founders building with AI tools (Lovable, Cursor, Bolt, v0, Replit), Idea Bob also generates a builder-ready prompt: a self-contained brief with goal, context, files to touch, acceptance criteria, and do/don't guidelines you can paste straight into your AI builder.

How long does validation actually take?

The initial Opportunity Score returns in under 60 seconds. The full validation pipeline covers Pressure Test, Deep Validation, Market Research and Competitor Analysis. It completes in 5-15 minutes total, running in parallel as background jobs.

Compare that to the traditional path: 2-3 weeks of manual market research, 10+ Mom Test interviews, a competitor spreadsheet, and a financial model. Idea Bob doesn't replace customer interviews, but it tells you whether the idea is worth doing those interviews for.

Frequently asked questions

Is Idea Bob free to use?

Yes. The Free plan gives you 3 idea scores per month. Hobbyist is $12/month USD, or $10/month billed yearly, for 25 AI analyses a month and the validation pipeline. Builder is $29/month USD billed yearly, or $49 billed monthly, for unlimited AI analyses.

What AI model does Idea Bob use?

Primary scoring uses Google Gemini 3 Flash with automatic failover to GPT-class models for resilience. Live market data comes from Firecrawl scraping Reddit, Hacker News, X, and competitor sites in real time.

Will my idea be visible to other people?

No. Your ideas are private by default with row-level security. You can opt to publish to the public Gallery if you want feedback, but it's never automatic.

Does Idea Bob replace customer interviews?

No. It tells you whether your idea is worth interviewing customers about, then generates the Mom Test scripts to run those interviews properly. Talking to real users is irreplaceable.

What if my idea isn't AI-related?

Idea Bob is tuned for AI / SaaS / digital products built by indie hackers and solo founders. Non-tech ideas (restaurants, physical products) will get a score but the framework is less calibrated for them.
