ShipFit
- Built to disagree. 24% of ideas get a Kill verdict against live data thresholds, not vibes
- Forced 9-stage sequential decision sequence. Each stage depends on the last
- Live competitor data with real URLs and prices sourced via search APIs at run time
- Customer signal pulled from G2 / Trustpilot / Reddit / App Store reviews, not generated by chat
- Named buyer personas with willingness-to-pay $ amounts, CAC and decision timeline
- Pricing architecture with Van Westendorp methodology, MVP scope with Lean / Balanced / Full packages
- Channel-specific launch playbook with conversion tracking, not a generic launch roadmap
- Exports to Cursor, Claude Code, Lovable, Replit, Windsurf, v0 and Gemini with tool-optimised prompts
- 55 named frameworks (Mom Test, Van Westendorp, Jobs-to-be-Done, 7 Powers, Blue Ocean) applied with scoring rubrics
- Not a chatbot. ShipFit is a structured 9-stage process, not a back-and-forth conversation
ValidatorAI
- Friendly chat interface and big community. 300,000+ founders have used Val, low barrier to start
- Bundles AI-generated landing page and a 14-step launch roadmap with the idea check
- Trained to be helpful. Default tone is encouraging. Rarely returns a 'stop building this' verdict
- No forced sequential decision process. Chat plus a roadmap, not nine decisions that depend on each other
- Frameworks referenced in chat, not applied systematically with scoring rubrics. No Mom Test / Van Westendorp / JTBD by name
- No buyer personas with explicit willingness-to-pay $ amounts or CAC numbers
- No MVP scope with Lean / Balanced / Full packaging or feature prioritisation
- No pricing architecture. Van Westendorp methodology and competitive pricing positioning not applied
- No exports to coding tools (Cursor, Claude Code, Lovable, Replit, Windsurf, v0, Gemini)
Val says yes. ShipFit says prove it.
Open ValidatorAI. Type an idea. Val will be friendly, helpful and almost certainly positive. Try this experiment: type a deliberately weak idea and see if it kills it. It won’t. It will find reasons to be encouraging.
That isn’t a bug. Val is a chat experience layered on a large language model with a startup-flavoured system prompt. Chat experiences are tuned for helpfulness, not honesty. The default behaviour of every LLM-based chatbot is to find the most agreeable version of an answer.
ShipFit is built the other way. The job is to disagree with you when the data says no. 24% of ideas that go through the full 9-stage sequence get a Kill verdict against live market data. Not vibes. Real competitor pricing, real complaint patterns, real opportunity scores.
9 decisions ValidatorAI doesn’t force
Val gives you a chat, a 0-100 score and a 14-step launch roadmap. ShipFit gives you 9 forced sequential decisions in a fixed order because 25 years of launching products taught the founder which decisions actually matter and in which order.
- Worth Building? Market verdict with real competitor URLs and prices
- Who Pays? Named buyer personas with willingness-to-pay $ amounts
- What Hurts? Pain points ranked by severity from real G2 / Trustpilot / Reddit data
- How to Win? Competitive positioning against real competitors
- What’s V1? MVP scope with Lean / Balanced / Full packages
- How to Charge? Pricing architecture with Van Westendorp methodology
- Will They Pay? Behavioural validation with landing page copy and traffic templates
- How to Launch? Channel-specific playbook with conversion metrics
- What to Export? Tool-optimised prompts for Cursor, Claude Code, Lovable, Replit, Windsurf, v0, Gemini
You can’t price before you’ve defined the buyer. You can’t scope the MVP before you’ve ranked the pain. That ordering is the product.

The bottom line
Val is a friendly chat with a launch roadmap and a generated landing page. ShipFit is a forcing function with live data, Van Westendorp pricing, MVP packaging and a coding-tool export.
Most founders comparing the two have been “validating” with Val for weeks. The conversation feels productive. They still don’t have a buyer with a price, an MVP scope or a coding-tool prompt. That’s the pattern Val produces by design.
Spend $5 on ShipFit’s Quick Take. 2 minutes. Live data. Real verdict.

The 9-step playbook from market verdict to ship-ready spec.
The Mom Test is Rob Fitzpatrick's framework for customer interviews that generate real signal. Not praise. Three rules, applied step-by-step, with examples.
The Van Westendorp framework uses 4 questions to surface a defensible price range. Here's how to run it, interpret the results, and avoid the usual mistakes.
Most founder market research is a TAM slide that nobody believes. The numbers that actually matter are smaller, harder to defend, and tell you whether the market exists for the ten-customer version of your business.
Most founders confuse idea validation with idea-receiving-encouragement. The two have nothing in common. Here's what real validation looks like, and the four methods that actually produce it.
Does each customer make you money? Or cost you money?
Run nine framework-backed decisions in order before writing code: define the buyer, prove the pain is painful, name the winning angle, scope V1 to the smallest test of the hypothesis, get behavioral evidence (paid pre-orders, signed letters of intent, or credit cards on file from a Fake Door Test), then ship. Most failed startups skipped at least three of those nine. Plan to spend two to four weeks on this. It saves six to nine months of building the wrong thing.
For indie hackers who've wasted months on dead ideas. ShipFit forces 9 decisions before you write a line of code. Proven frameworks, exports to Cursor.
If you want a conversation partner, Buildpad. If you want to stop researching and ship, ShipFit. Both solve different problems for different founders. Don't pick on hype.
