“Criei em 3 dias, totalmente vibe-coded, um (micro) SaaS que analisa seu LinkedIn e diz onde melhorar. Em 1 semana: R$ 7k faturados.”
Editor's note: Bruno Bertolini is a developer in Florianópolis, Brazil, who says he has been shipping code for about 20 years. He wrote that he built Karvi in 3 days, "totalmente vibe-coded" (fully vibe-coded), and that it billed R$7k in its first week; he does not name the AI tool. In English, the quote reads: "I built in 3 days, fully vibe-coded, a (micro) SaaS that analyzes your LinkedIn and tells you where to improve. In 1 week: R$7k billed." The link in his post goes to karvi.app, and TrustMRR links the listing to his X account. TrustMRR lists Next.js, Neon, Vercel, Resend and Stripe. The quote is from his X post of Feb 11, 2026.
