From $200K in Debt to $50K/Month Building Mobile Apps - Adam Liddell's Story

TL;DR: Adam Liddell's web agency collapsed when Wix and Squarespace disrupted the market, leaving him with $200K in debt and burnout. After rebuilding confidence through lawn mowing, he discovered a gap in the market for lawn care management apps. His first app failed, so he challenged himself to build one app per month to learn faster. This rapid iteration revealed that building apps to sell was unsustainable, so he pivoted to building a portfolio of smaller apps generating recurring revenue. When ChatGPT launched, he accelerated to building 9 apps in one month, creating enough portfolio revenue to escape the build-sell cycle. A breakthrough came when he tested new paywall and onboarding flows on his YouTube channel, which 5x'd his revenue from $10K to $50K per month overnight. He's now built 50+ apps, paid off all debt, and earns $50-60K monthly from his app portfolio.
