@starterstory: Solo founder built a $50K/month app with this exact tech stack: Jake is 24. He launched Erly (an alarm app where you do pushups to turn off the alarm) at the end of 2025 and hit $50K/month in 4 months. 200K+ downloads. One-man show. Here’s the full stack he runs it on: > Firebase for database, auth, cloud functions > Superwall for paywall + subscriptions > OpenAI for the AI API > Mixpanel for in-app analytics > Claude Code for actually building the app > Heroi for influencer tracking + payments > Sideshift for UGC creator sourcing > Instantly for mass influencer outreach > Cal for booking, Agree for contracts > QuickBooks + 1Password + Google Sheets to run the business The app itself is dead simple. The stack is dead simple. The whole edge is on the marketing side, where he pours everything into influencer videos with view guarantees at $2-3 CPM. “Building is easy now. If nobody knows about your app, it doesn’t exist.”
