ShipFit
- Forced 9-stage sequential decision sequence with Ship / Pivot / Kill verdicts. No skipping. Each stage builds on the last
- Live competitor data from search APIs at run time. Every competitor has a real URL, every price has a source link
- Real customer complaints sourced from G2 / Trustpilot / Reddit / App Store reviews, not generated text
- MVP scope with Lean / Balanced / Full packages, feature prioritisation and a build timeline
- Van Westendorp pricing methodology applied by name, with competitive positioning map and tier recommendations
- Behavioural validation with landing page copy, traffic templates and conversion tracking checklist
- Channel-specific launch playbook matched to your buyer, with copy templates and success metrics
- Exports to Cursor, Claude Code, Lovable, Replit, Windsurf, v0 and Gemini with tool-optimised prompts
- 55 named frameworks attributed (Christensen, Fitzpatrick, Vohra, Helmer, Van Westendorp, JTBD) applied at the right stage
- 20 minutes for the full sequence, not 120 seconds. If you only want a fast confidence number, this isn't it
- No brand-asset or AI ad generation. Logos, colour palettes and ad creative aren't part of the playbook
IdeaProof
- Fast. 120 seconds from idea to a 0-100 viability score
- Broad output bundle. Score, SWOT, brand archetype, logo, AI ads, landing pages and email sequences in one place
- One-shot report, not a forced sequential decision process. No Ship / Pivot / Kill verdict on individual stages
- Frameworks not attributed. No Christensen, Fitzpatrick, Vohra, Helmer or Van Westendorp by name
- 89% accuracy claimed against 10,000+ user follow-ups, but no published methodology document
- No exports to AI coding tools. PDF and brand-asset output only, no Cursor / Claude Code / Lovable handoff
- No live G2 / Trustpilot / Reddit complaint mining. Customer signal is generated from inputs, not pulled from real reviews
- No Lean / Balanced / Full MVP packaging. MVP roadmap is generic, not scope-tiered
- Pricing strategy generated, but Van Westendorp methodology and competitive pricing positioning not named
A score is a number. A playbook is a plan.
IdeaProof’s pitch is fast. A 120-second viability score, a SWOT, target audience and a marketing bundle: brand archetype, logo, colour palette, AI-generated ads, landing pages and email sequences. The output is broad. It is also a one-shot. You type, you wait, the system produces the whole bundle.
ShipFit is shaped the other way. 9 forced decisions, in order. Each one builds on the last. You can’t skip ahead. You walk out with a named buyer, real competitor URLs, a Van Westendorp pricing tier, a Lean / Balanced / Full MVP scope, a channel-specific launch playbook and exports for seven AI coding tools.
The IdeaProof score and the ShipFit playbook are different end states. The score answers “should I think about this for longer?” The playbook answers “what should I build, for whom, at what price, and how?“
9 decisions IdeaProof doesn’t force
IdeaProof produces its outputs in parallel from one prompt. ShipFit’s 9 stages run sequentially because each one depends on the last.
| Stage | What ShipFit produces |
|---|---|
| 1. Worth Building? | Market verdict with real competitor URLs, real prices, real complaints. Ship / Pivot / Kill |
| 2. Who Pays? | Named buyer personas with willingness-to-pay, CAC and decision timeline |
| 3. What Hurts? | Pain points ranked by severity and frequency from real review data |
| 4. How to Win? | Side-by-side competitive positioning with real pricing and feature gaps |
| 5. What’s V1? | Lean / Balanced / Full MVP packages with prioritisation and build timeline |
| 6. How to Charge? | Pricing architecture with Van Westendorp methodology and tier recommendations |
| 7. Will They Pay? | Landing page copy, traffic templates, conversion tracking checklist |
| 8. How to Launch? | Channel playbook with copy templates and success metrics |
| 9. What to Export? | Cursor, Claude Code, Lovable, Replit, Windsurf, v0 and Gemini configs |
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
IdeaProof gives you a score in 120 seconds plus a marketing kit. ShipFit gives you the nine decisions and the coding-tool handoff that come between “this might work” and “this is shipping next week”.
Both have free entry. Both cost about the same to go deeper. Only ShipFit replaces the “what do I actually build, for whom, at what price” gap with a forced sequence and an export prompt.
If you’re past the score-curiosity stage and want a build plan, start with ShipFit.

The 9-step playbook from market verdict to ship-ready spec.
Activities, Environments, Interactions, Objects, Users. The AEIOU observation framework gives field research a structure so that notes stay comparable.
The JTBD framework in plain terms: the four forces of progress, the switch timeline, and how the Christensen and Ulwick schools actually differ.
Default-prompted AI is a slop machine: agreeable, plausible-sounding, useless for validating an idea. Here's how to use AI for the parts where it actually adds signal, and where to keep it out of the way.
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.
Van Westendorp in 4 numbers. Skip the survey-platform fees.
Two to four weeks of focused work for a single idea. Stage 1 (market verdict) takes a day. Stages 2-3 (buyer + pain) take a week of interviews. Stage 4 (positioning) takes two days. Stage 5 (V1 scope) takes a day. Stages 6-7 (pricing + behavioral evidence) take 1-2 weeks because you need 20+ buyers and a Fake Door Test running. ShipFit compresses the decision time to 30-60 minutes; the gating work is the human conversations between stages.
Validation for non-technical founders using AI builders and no-code. The bottleneck isn't building anymore, it's deciding what to build. ShipFit decides.
PRD generators turn your input into a tidy requirements doc fast. ShipFit forces the decisions that make the doc worth writing, then exports the spec. A polished PRD for an unvalidated idea is just well-formatted fiction.
