ShipFit
- Forced 9-stage SEQUENTIAL decision sequence. Stage N depends on stage N-1. No siloed agents
- Ship / Pivot / Kill verdict on every stage. 24% of ideas killed against live data thresholds
- Live competitor URLs and prices from search APIs at run time. Not AI-generated persona prose
- Customer signal pulled from G2 / Trustpilot / Reddit / App Store reviews
- Buyer personas with willingness-to-pay $ amounts, CAC and decision timeline
- MVP scope with Lean / Balanced / Full packages and feature prioritisation
- Pricing architecture with Van Westendorp methodology and competitive positioning
- Behavioural validation with landing page copy, traffic templates and conversion tracking
- Channel-specific launch playbook with copy templates and success metrics
- 50+ named frameworks attributed (Christensen, Fitzpatrick, Vohra, Helmer, Van Westendorp, JTBD)
- Built for builders, not fundraisers. Output is ship-ready, not deck-ready
- No pitch deck, no investor financial model, no Business Model Canvas. If you're raising, the deliverable shape is different

Sequence beats parallel agents
AI Cofounder runs 26 AI agents in parallel. Persona Generator, MVP Planner, Business Model Canvas, Pitch Deck, Investor Discovery, Funding Strategy and 20 more. The end state is a stack of investor-ready deliverables: business report in Word and PDF, pitch deck, Business Model Canvas, tech stack and wireframes.
ShipFit runs 9 decisions in sequence. Each one depends on the last. The Who Pays decision uses the Worth Building output. The How to Charge decision uses the Who Pays and How to Win outputs. The MVP scope uses the pain ranking. The launch plan uses the buyer.
Parallel agents skip decisions because nothing forces one agent to wait for another. Sequence forces them.
9 decisions AI Cofounder doesn’t force in sequence
26 agents producing artifacts in parallel is not the same as 9 decisions in order. ShipFit’s stages depend on each other on purpose.
- Worth Building? Market verdict from live G2 / Reddit / competitor URL data
- Who Pays? Personas built on the market signal from stage 1
- What Hurts? Pain ranked for the personas in stage 2
- How to Win? Positioning against real competitors from stage 1, for the buyer in stage 2, against the pain in stage 3
- What’s V1? MVP scope addressing stage 3’s pain for stage 2’s buyer
- How to Charge? Pricing for stage 5’s scope, stage 2’s buyer, against stage 4’s competitors
- Will They Pay? Landing page copy for stage 6’s price and stage 2’s buyer
- How to Launch? Channels picked for stage 2’s buyer with stage 7’s copy
- What to Export? A tool-optimised prompt that encodes every decision above
In AI Cofounder’s parallel model, the persona agent doesn’t know which buyer the MVP agent assumed. The pricing agent doesn’t know what the persona agent decided. The artifacts get assembled, but the decisions don’t chain.

The bottom line
AI Cofounder is excellent at producing investor-ready artifacts in parallel. ShipFit is excellent at forcing the nine decisions that determine whether the artifacts (or the product) are worth producing at all.
If you’re raising and need the deck format fast, AI Cofounder’s 26-agent stack fits. If you’re shipping and need a forced decision sequence with G2 / Reddit signal, Van Westendorp pricing and a coding-tool prompt, ShipFit’s 9 sequential stages fit.
For builders, $5 for a Quick Take is the cheapest way to test the difference.

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 for any product. Here's how to run it, interpret results, and avoid the cheapest 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.
