About

Begin is an AI app builder that turns a prompt or a pasted domain into a shippable product. It produces 1:1 website clones from any domain, native iOS apps (SwiftUI, TestFlight-ready), native Android apps (Kotlin, Play Console-ready), and Chrome extensions (Manifest V3, Web Store-ready). Teams use Begin for marketing and product sites, agency client rebuilds and white-label delivery, and rapid founder prototyping, with unlimited projects, custom domains, and shared team workspaces.

About

Preuve AI is market research and competitive intelligence for founders, and the white-label engine agencies, accelerators and consultants use to pre-qualify inbound startups. Real signals, not a confident AI score with nothing behind it. 10 AI agents scan 60+ live sources. The free Reality Check takes about 60 seconds, the full Founder Report about ten minutes. The verdict has to be earned. In our July 2026 benchmark of 6,000+ analyses, the median idea scored 54/100 and 17.5% reached 70, the line for a go. * 21-section Founder Report: competitors, market sizing, demand signals, risks and a go-to-market plan * Up to 15 competitors with funding, pricing and positioning * 3 pivots when the evidence points away from the idea * Data from Crunchbase, G2, Google Trends, SEC EDGAR and Reddit * For agencies: a white-label intake scanner and client reports under your brand Founder Report $59 one-time. Consultant workspace $99 once, then $59 per client report.
