IdeaProof: prices, credits and what you get

What IdeaProof is

IdeaProof.io is an AI platform for startup idea validation and launch material. Its terms name the operator as NT VENTURES S.R.L., and its prices include Italian VAT. You describe your idea in one sentence or with a URL.

The validation step returns a viability score out of 100, green flags, risk flags and a GO / NO-GO verdict. The site says a validation takes about 2 minutes, and the full journey about 30 minutes.

That journey has 6 steps: Validation, Market Analysis, Business Plan, Brand Strategy, Brand Visuals and Marketing Suite. Progress saves at each step, so you can stop after any of them.

Who it is for

The pricing section of IdeaProof's home page matches each plan to a founder type. Starter is for founders exploring 1 specific idea. Builder is for founders comparing or launching 2 ideas. Founder is for founders ready to launch and scale.

Prices and credits

Credits pay for every AI feature. All packs are one-time payments with VAT included, and the site says purchased credits never expire.

The pricing page gives the credit cost of each step:

A worked example from those numbers: validation, market analysis and brand strategy cost 40 + 50 + 50 = 140 credits, which fits in the Starter's 150. All six steps for one idea cost 640 credits, so they need the Builder pack or larger.

The free option

Every account starts with 40 free credits. The site says this is enough for 1 full validation, with no credit card. You need to sign up to use them.

The home page shows a complete sample report for a "No-Code App Builder" idea, which you can read without signing up. Market analysis and the later steps cost more credits than the free 40.

How it shows sources and scores

The home page says every claim links back to its source, and that citations are clickable in the live report. The research methodology page says IdeaProof collects data from 60+ authoritative sources, refreshed weekly, and grounds its agents in its own knowledge base built from past validations.

The research methodology page names the AI providers by task. Gemini runs standard validation, research and synthesis. Claude runs Pro validation synthesis and business plans. OpenAI runs Pro deep research with web search. Perplexity runs cited live-web lookups. The page says not every provider is used in every report.

The same page publishes the score formula. Ten criteria are each scored from 0 to 100 and weighted. The largest weights are problem-solution fit (17%), value proposition (15%), competition level (14%) and timing (12%). Each red flag takes off 2 points (3 when the base score is under 45), up to 5 flags. Each green light adds 3 points (2.5 when the base is under 45), up to 4. The verdict bands are STRONG at 75+, PROMISING at 60 to 74, REFINE at 45 to 59 and RECONSIDER below 45.

IdeaProof also states the limits of its score. It calls the score a model assessment of the evidence found, not a probability of business success. It reports an internal match rate of about 89% between its scores and outcomes users later reported, and labels it internal and uncertified.

What to check before paying

• Which steps you need. If you want validation and market analysis only, that is 90 credits. The business plan, visual identity and marketing suite add 500 more.
• The withdrawal terms. The terms give consumers a 14-day right of withdrawal. That right ends once the consumer uses the first credit of the pack, and it does not apply to business users.
• The sources in your own report. The FAQ on IdeaProof's home page asks you to check the cited sources before you make a decision. Open the ones behind the market size and the main competitors.
• Who owns the output. The same FAQ says you own it, with commercial use granted, and that IdeaProof does not train models on your idea content.

How it differs from Preuve AI

IdeaProof is a separate tool, not a Preuve AI product. This reference features Preuve AI. Both tools return a verdict on an idea and link their findings to sources. They differ in how you pay and in how far past the verdict they go.

• How you pay. IdeaProof sells credit packs in euros from €19.99, with 40 free credits at sign-up. Preuve AI starts with a free scan with a free account and no card, then a $59 one-time Founder Report.
• Scope. IdeaProof credits extend from validation into business plans, brand strategy, logos and marketing assets. Preuve AI stays on the build decision. Its report is an evidence report, not a daily planning workspace.
• Report content. Both paid reports cover TAM/SAM/SOM and competitors. On IdeaProof this is the Market Analysis step. The Preuve AI Founder Report lists up to 15 competitors and adds Founder Fit and 3 pivots. Founder Fit checks the idea against your time, runway and skills.

If you want to compare the two on your own idea, run both free options and read the sources each one cites. Test your idea with Preuve AI.
