Three plans. Three outcomes.
Pick the founder you are today. Each plan is built around a real outcome — not a feature list.
Mia
the side-project tester
- I'll know in 30 minutes if my idea is worth my weekends.
- I get a real market size and 5–10 competitors — not just a hunch.
- I walk out with a PDF I can actually show my advisors.
Marco
the full-time founder
- I walk out with everything I need to start building Monday.
- My business plan, brand and identity are investor-ready, in one sitting.
- I have ad copy and GTM messaging ready — no more blank page.
Sara
the serial launcher
- I can launch two ideas end-to-end without thinking about credits.
- I can take 7 ideas through validation, market, plan, brand, visuals and marketing.
- I keep validating as I iterate — with room left after 7 complete journeys.
Every plan: PDF exports, email support, lifetime credits.
One currency. Six outcomes.
Credits power every AI feature on IdeaProof. Here's exactly what each one costs — so you know what your plan unlocks.
