A free, open-source AI skill that validates any startup idea with a VC-grade 7-dimension scorecard — the same framework real investors use to evaluate seed-stage companies.
Describe your idea in a few sentences. Get back a weighted score, honest strengths/risks analysis, and a concrete next step.
- 7-dimension weighted scorecard with evidence-backed rationales
- Weighted total score (X.X / 10) with investment priority rating (Strong / Promising / Weak / Pass)
- Key strengths — what's working in your favor
- Critical risks — with early warning signals and mitigation tactics
- 7-day action item — one specific thing to do this week
- Adaptive research — uses web search when available, falls back to LLM knowledge gracefully
- Multi-language — responds in whatever language you use
| Dimension | Weight | What It Evaluates |
|---|---|---|
| Market | 25% | TAM/SAM/SOM, growth rate, why now |
| Founder-Market Fit | 25% | Domain expertise, unique advantages, network |
| Problem-Solution Fit | 15% | Pain severity, differentiation, willingness to pay |
| Competition | 10% | Landscape, moat potential, whitespace |
| Business Model | 10% | Unit economics, pricing power, path to profit |
| Go-to-Market | 10% | Path to first 100 customers, channel feasibility |
| Execution Risk | 5% | Buildability, capital needs, time to MVP |
Weights reflect actual seed-stage VC priorities: Market + Founder-Market Fit = 50% because investors bet on big markets and strong teams above all else.
