Preuve AI scores a business idea using live data from more than 60 sources, mapping competitors, demand signals and risks before any building starts.

About IdeaFast

IdeaFast is a research tool that mines Reddit for recurring problems people describe. Founders choose one or more subreddits, and the scan groups posts into pain points scored from 0 to 100, each showing who has the issue, what they are asking for, a suggested build angle and links to the original threads. Signals like willingness to pay or requests for a tool are flagged. Paid packs add more subreddits per scan, a three month lookback, more generated ideas and validation reports, with PDF, CSV and JSON exports. There is no subscription, only scan packs bought once: the first scan is free, then 19 USD buys 40 scans and 49 USD buys 100.

About Preuve AI

Preuve AI is an idea validation tool for founders who want evidence before committing to a new venture. After a short description of the idea, its agents scan more than 60 live sources, among them Reddit, G2, Product Hunt, Google Trends and Crunchbase, and return a viability score, a map of as many as 15 rivals along with their funding and prices, and likely blind spots. The paid Founder Report adds sized markets, scored risks with three pivot suggestions, a go to market plan, a founder fit check and a business plan PDF, with each claim tied to a source link. A free scan takes about a minute, and the Founder Report costs 59 USD once.
