Preuve AI is a startup validation tool designed for founders, indie hackers, and solo builders who need a data-driven reality check before investing months into a new idea. The tool scans over 50 live data sources—including Crunchbase, Google Trends, Reddit, Product Hunt, and G2—to generate a viability score, map up to 15 competitors with funding and pricing data, and surface blind spots that could derail the business. Since 2026, over 5,500 startup ideas have been analyzed across 13 industries, and according to CB Insights, 42% of startups fail because there is no market need—precisely the blind spot Preuve AI catches. With a free scan taking about 60 seconds, it delivers a clear go/no-go verdict, making it an essential first step for anyone serious about building a business.
The core problem Preuve AI addresses is the high failure rate of startups due to insufficient market validation. Many founders rely on anecdotal feedback from friends and family, or get overly optimistic scores from generic AI tools, leading them to build products nobody wants. Preuve AI solves this by providing live competitor data, real demand signals, and an objective viability score that reflects actual market conditions. This matters because it prevents founders from wasting months or years on ideas that have no chance of success. The tool forces users to confront hard truths early, allowing them to pivot or abandon ideas before significant resources are committed. By linking every claim to its source, Preuve AI ensures that the validation is transparent and trustworthy, not just a black-box opinion.
One major feature group is the Viability Score and Competitor Mapping. Ten specialized AI agents run in parallel, analyzing 50+ live sources to generate a score out of 100. The scoring model runs multiple times; if runs disagree, the system iterates until the verdict converges. This ensures that the score is reliable and not a fluke. The competitor mapping profiles up to 15 competitors, showing their pricing, funding, estimated users, market share, and exploitable weaknesses. For example, when analyzing a SaaS idea, Preuve AI might identify that the main competitor, Maze, is tethered to human response times, suggesting that speed could be your entry point. Each competitor profile includes live intel, market pulse, and a list of sources, helping founders understand the competitive landscape and find gaps to exploit.
Another key feature is Market Sizing and Community Signals. Preuve AI estimates the total addressable market (TAM), serviceable addressable market (SAM), and serviceable obtainable market (SOM), along with market growth percentages. It also pulls community signals from Reddit, Twitter/X, and other platforms to gauge demand and pain points. For instance, the tool can detect that potential customers are complaining about the high cost of existing solutions, or that there is a surge in discussions around a specific need. This feature helps founders validate that real people are experiencing the problem they aim to solve, and that the market is large enough to sustain a business. All data is linked to its source, so founders can dive deeper into the evidence if needed.

Preuve AI also offers Smart Pivot Recommendations and a comprehensive Action Plan. When an idea scores low, the tool doesn't just label it as bad; it provides three specific pivots to improve the score, with an average lift of +8 points. These pivots are based on the idea's unique weaknesses, such as suggesting a niche audience or a different business model. The Action Plan breaks down what to do in the first 48 hours, including signing up for free tiers of competitor tools, creating comparison one-pagers, and setting up waitlists. It also includes a validation checklist with milestones to confirm trust, pricing power, and retention. This turns a negative result into a constructive roadmap, saving founders weeks of guesswork.
The overall workflow is simple: a user describes their startup idea in one or two sentences, and Preuve AI returns a free scan with a viability score, main risks, and two competitor previews. If they purchase the Founder Report for $29, they get a full breakdown: verdict, what to fix, early buyer personas, proof of pain points, three pivots, up to 15 competitors with pricing and weaknesses, and a defensible business plan. Every key claim is linked to a source. The report is one-time and yours forever, with unlimited future updates. For ongoing monitoring, Radar Pro re-scans monthly and flags threats, starting at $19 per month. The entire process takes about 60 seconds for a free scan, and the Founder Report is delivered in minutes.
Concrete use cases include validating a SaaS idea before writing code, iterating on an idea after receiving feedback, preparing investor-ready materials like an executive summary and investment memo, and monitoring market shifts after launch. For example, Uxia, a startup that raised $1M pre-seed, used Preuve AI to generate a comprehensive report that included an action plan, competitor analysis, and market sizing. Founders report discovering copycats, gaining clarity for fundraising, and saving months by avoiding dead-end ideas. One founder said, "The data are on point. I even discovered a copycat of my idea that launched weeks ago!" Another noted that the pivot recommendation alone was worth the entire price.
