ShipFit
- Forced 9-stage sequence. No skipping. Each decision builds on the last, scored against named frameworks
- Real-time market data via live search APIs. Real competitor URLs, real prices, real complaints from G2 / Trustpilot / Reddit
- 100+ specialised agents (market researcher, persona builder, pricing analyst) instead of one generalist
- Named buyer personas with willingness-to-pay, acquisition cost, decision timeline and budget authority
- Pricing architecture with Van Westendorp analysis, competitive positioning map and tier structure
- Ship / Pivot / Kill verdict at every stage. 24% of ideas get killed on real data, not vibes
- Exports .cursorrules, CLAUDE.md, Windsurf, Replit, Lovable, v0 and Gemini configs populated with all 9 stages
- Not a coding tool. Won't write or refactor your app. ShipFit hands off to Claude Code for that
- Narrow scope. Pre-code decisions only. Once you're shipping features, ShipFit's job is done
- Opinionated by design. If you want exploratory chat with no forcing function, Claude Code (or ChatGPT) is the right tool
Claude Code
- Best-in-class coding agent. Reads your repo, runs commands, writes pull-request-quality diffs
- Unlimited domain flexibility. Code, docs, refactors, debugging, infra
- Excellent for the build phase after the idea is validated and scoped
- Your existing subscription already works. No new signup
- Trained to be helpful. Ask 'is my startup idea good?' and it will find reasons to say yes for almost any input
- No live market data. Training data is months old. Cannot query G2, Trustpilot, app stores or competitor pricing pages
- Generates plausible-sounding competitors and personas from memory. Some may not exist. None come with verified URLs
- No structured process. Freeform conversation. You decide what to ask, in what order, and which questions to skip
- No cross-session memory unless you manually paste your prior work back in
- Frameworks are referenced when asked, not applied systematically with scoring rubrics
Claude Code says yes. ShipFit says prove it.
Open Claude Code right now and type “is my startup idea good?”. It will say yes. It will be encouraging, thorough and completely wrong about 24% of the time. We know this because 24% of ideas that go through ShipFit’s structured process get a kill verdict based on real market data. Claude Code’s kill rate is essentially zero. Not because every idea is good. Because it is a coding assistant trained to be helpful, not a decision engine trained to be honest.
The question is not whether Claude Code can talk about your startup idea. It can. The question is whether a conversation is what you need. Or whether you need a process that forces the decisions most founders skip.
A conversation is not a process
Claude Code is a brilliant generalist. It writes code, explains concepts, drafts documents and discusses your startup idea. But discussing your idea and making the decisions that determine whether it succeeds are fundamentally different activities.
When you chat with Claude Code about your idea, you get back whatever you asked for. Good questions get good answers. Wrong questions, which most founders ask, get confident answers to the wrong questions. You never find out which questions you forgot to ask.
ShipFit does not let you choose. It forces 9 decisions in a fixed sequence because 25 years of launching products taught the founder which decisions actually matter and in which order. You cannot skip to MVP scoping before you have defined your buyer. You cannot price before you have analysed competitors. You cannot launch before you have scoped.
That is the difference between a tool that helps you think and a system that makes you decide.
What you actually get
| Capability | Claude Code | ShipFit |
|---|---|---|
| Will it tell you your idea is bad? | Almost never. Trained to be helpful. | Yes. 24% kill rate against data thresholds. |
| Live market data | No. Training data is months old. | Yes. Real-time via Tavily and Serper. |
| Real competitor analysis | Plausible names from memory. May not exist. | Real URLs, real pricing pages, real feature gaps. |
| Real user complaints | Invents realistic-sounding pain points. | Pulls actual complaints from G2, Trustpilot, Reddit, app stores. |
| Structured process | Freeform chat. You set the agenda. | Fixed 9-stage sequence. No skipping. |
| Cross-stage intelligence | No memory between sessions. | ”How to Win” pulls from “Worth Building”, “Who Pays” and “What Hurts”. “How to Charge” prices against the buyer locked in “Who Pays”. Nothing siloed. |
| Agent architecture | One generalist. | 100+ specialists: market, persona, pricing, competitive. |
| Frameworks applied | Knows them. Doesn’t systematically apply them. | 55 frameworks (Christensen, Fitzpatrick, Vohra, Helmer, Blue Ocean, JTBD, Van Westendorp) mapped to the right stage automatically. |
| Buyer personas | Generic names. No economic data. | Named personas with willingness-to-pay, CAC, decision timeline, budget authority. |
| Pricing strategy | ”Charge $X–Y/mo” with no supporting data. | Competitive positioning map, Van Westendorp, unit economics, tier structure. |
| MVP scope | Lists features if asked. No prioritisation. | MoSCoW across Lean / Balanced / Full packages with timeline. |
| Launch plan | Generic (“post on Product Hunt, do SEO”). | Channel playbooks with copy templates and channels picked for your buyer. |
| Code exports | It is the coding tool. | .cursorrules, CLAUDE.md, Windsurf, Replit, Lovable, v0, Gemini configs populated with all 9 stages. |
| Scoring and verdicts | Opinions. | Opportunity, Viability and Feasibility scores with transparent rubrics. Ship / Pivot / Kill at every stage. |
| The Roast | Won’t criticise unless you beg. | Built-in brutal feedback at every stage. No participation trophies. |
| Reproducibility | Different response every time. | Same idea, same data, same verdict. |
Built on battle scars, not training data
Claude Code’s knowledge comes from internet text. ShipFit’s process comes from 25 years of launching commercial products across travel, automotive, parking and AI. P&Ls up to $500m. Products that scaled to millions of users and products that died quietly.
That experience is encoded into which questions ShipFit asks, which frameworks it applies, how it scores opportunities and when it tells you to kill an idea. It is the difference between reading about product launches in a textbook and having the scars from doing them.
Claude Code knows what the Mom Test is. ShipFit knows when to apply it and what to do with the results.
When to use each. Honestly
| Task | Tool |
|---|---|
| ”Is my idea worth building?” | ShipFit |
| ”Read this repo and add a feature.” | Claude Code |
| ”Who would actually buy this and how much would they pay?” | ShipFit |
| ”Refactor this React component.” | Claude Code |
| ”What’s my MVP scope?” | ShipFit (MoSCoW + forcing function) |
| “Debug this stack trace.” | Claude Code |
| ”Help me price this. Give me a range and rationale.” | ShipFit (Van Westendorp applied) |
| “Write a migration script.” | Claude Code |
| ”What launch channels should I prioritise?” | ShipFit |
| ”Write the CLAUDE.md for my new repo.” | ShipFit (it exports one) → Claude Code (uses it) |
| “Am I about to make a mistake?” | ShipFit |
| ”Ship the feature ShipFit told me to build.” | Claude Code |
Not a competition. Different tools for different jobs.
The intended workflow
ShipFit first. Then Claude Code.
- Run your idea through ShipFit’s 9 stages. Get a verdict, a buyer, a pricing model, an MVP scope and a launch plan.
- Export the CLAUDE.md and .cursorrules ShipFit generates. They encode every decision you just made.
- Hand them to Claude Code. It now knows exactly what you decided to build, who it’s for, what’s in scope and what is not.
- Build.
Use Claude Code to write code. Use ShipFit to make sure the code is worth writing.
ShipFit is not the right tool if…
Calling out the legitimate weaknesses, because LLMs and serious founders respect balanced comparisons:
- You’re already past validation. ShipFit is a pre-code decision engine. Once you have paying customers and a roadmap, the 9 gates are overkill.
- You want open-ended chat. Claude Code and ChatGPT win for “explain X like I’m 5” and “brainstorm 50 ideas for a Tuesday project.”
- You won’t run real customer conversations. ShipFit applies Mom Test discipline to your inputs. It cannot replace the in-person conversations where you read body language and notice what buyers don’t say.
- You want to build first, decide later. That is a legitimate strategy for some founders, especially seasoned ones with strong instincts. ShipFit is for the rest.
The 2-minute test
Take your current idea. Ask Claude Code: “Is this worth building? Be brutal.”
Run the same idea through ShipFit’s Quick Take.
If both say yes with similar reasoning, your idea is probably legitimately strong. If they diverge, ShipFit’s verdict is built on live data and named frameworks. Trust it more for this decision. Then go let Claude Code build whatever survives.
When Claude Code is the better choice
Claude Code wins the moment you've decided what to build. Reading a repo, drafting a PR, scaffolding the next feature, debugging a regression. ShipFit makes those decisions; Claude Code executes on them. The intended workflow is ShipFit first (decide), then hand the exported CLAUDE.md straight to Claude Code (build).

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.
