[Video] Kletchi, 22, came to the US from Nigeria with $100. The idea came from a genuinely awkward personal moment: he struck out with a girl → searched the App Store for “life advice” and found nothing → wrote himself a NestJS script using OpenAI to help reply to messages → at a Homecoming party, friends showed real interest in something he'd built for the first time → only then did he package it as an app (Social Wizard: screenshot a girl's IG story, drop it in, get reply lines). First sale of $10 in early 2024; cracked the distribution method 4 weeks later — $3.5K MRR in 2 weeks, $25K MRR in a month, roughly $250K collected over 6 months. His second app, Clean Eats (scan a food barcode → learn how it affects your skin and weight; core users are women 18-28), did about $10K in its first 2 weeks and was sold to a UK company 4 months later. Over 12 months the two apps totaled $1.5M and 700K+ downloads — with zero ad spend the entire way.
