What's breaking you right now
- You have no cofounder to disagree with you. The idea sounds great because the only person stress-testing it is the person who came up with it.
- Every hour is zero-sum. There's no teammate to parallelize with, so an hour spent on the wrong thing is an hour that never comes back.
- You context-switch between founder, builder, marketer, and support all day. Nobody owns 'is this even worth doing,' so it gets skipped.
- When you're stuck, there's no one across the desk to talk it through. You either spin in your own head or ask the internet and get noise.
- You can't outsource conviction. Investors and friends are too polite. You need a check that is structurally incapable of being polite.
How ShipFit helps
Manufacture the cofounder argument
Run the full 9-question flow and let it push back on your reasoning the way a skeptical cofounder would. About 24% of ideas come back with a Don't Ship verdict. That's the disagreement you don't have at home.
Triage before you spend a week
When every hour counts, run a Quick Take first ($5, ~2 min). Kill the weak idea before it eats a week of solo build time you can't get back.
Pick the one bet you can actually finish
Solo means you ship one thing at a time. Run two or three competing ideas through Quick Take and let the verdict tiers rank them, instead of going with whatever felt loudest.
Turn the decision into a spec you can build alone
Export the playbook straight to Cursor, Claude Code, or Lovable. The 9 decisions become a build plan, so you don't lose a day translating thoughts into a PRD nobody else will read.
Get unstuck without a sounding board
Stuck on pricing or who the buyer even is? The pricing stage (Van Westendorp) and buyer stage do the structured thinking you'd normally borrow a brain for.
Why solo founders, specifically
A solo founder has no structural disagreement. On a two-person team, one person says “are we sure about this?” and the other has to answer. Alone, you ask the question and you also get to dismiss it. The result is that bad ideas survive longer for solo founders than for anyone else, because nothing in the room is built to kill them. ShipFit exists to be that something.
The solo founder problem in 40 words
You are builder, marketer, support, and CEO at once. Nobody owns the question “is this worth doing at all,” so it gets skipped, and you find out the idea was dead only after you’ve built it. A forced check fixes that.
What you actually get
| You don’t have | ShipFit gives you |
|---|---|
| A cofounder to push back | 9 forced decisions that argue with your reasoning |
| Spare hours to waste | A ~2 minute Quick Take before you commit a week |
| A team to parallelize bets | Verdict tiers that rank competing ideas for you |
| A product manager to write the spec | An export to Cursor, Claude Code, Lovable, or v0 |
| A polite-free sounding board | The Roast, which is brutal by design |
How it fits your workflow
- New idea at the end of a long solo day. Run a Quick Take. ~2 minutes. Kill or commit before you sleep on it and over-invest.
- If it survives, run the full 9-question flow. ~15-20 minutes. Let it disagree with you on buyer, pricing, and scope.
- Export the playbook to your build tool. You’re now building against a plan, not a mood.
- Take the generated Mom Test questions to 3 real people. The interviews you can’t afford to waste are now pointed at the right buyer.
- Iterate or kill on real signal, not on how attached you’ve become.
No cofounder to convene. No team meeting. Just the structured pushback you’ve been doing without.
Start with Quick Take
Free tier: 3 credits/month, enough for a Quick Take and one decision. Paid: $5 for a one-off Quick Take on your next idea. Validate your business idea before you commit the only resource you have, which is you.
Frameworks you’ll use
- The Mom Test. So your few precious customer conversations actually tell you something.
- Van Westendorp pricing. For pricing without a partner to argue you off your guess.
- Jobs to be Done. For figuring out what your buyer is really hiring you to do.
Not the right fit if…
- You want a warm brainstorm partner who riffs along with you. Try Buildpad instead.
- You’re already past product-market fit and just need growth. This is a pre-PMF decision tool.
- You find blunt feedback demoralizing right now. ShipFit is built to disagree, and if that’s wrong timing for you, that’s fair.

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.
Gross burn lies. Net burn tells you the truth.
The state where a product satisfies a strong market demand from a specific buyer segment such that customer pull on the product exceeds the founder's effort to push it. Coined by Marc Andreessen in 2007 ('the only thing that matters'). Operational measure: 40%+ of active users would be 'very disappointed' if they could no longer use it (Sean Ellis test, popularized by Rahul Vohra at Superhuman in 2018). Below 40%, you don't have PMF yet, regardless of revenue or press.
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.
Lovable builds apps by chatting with AI: describe it, see it built in real-time, deploy. ShipFit makes 9 decisions before you open Lovable so you build the right thing. ShipFit even exports a Lovable-optimised prompt that encodes every decision. Use both. ShipFit first.
