Buying Businesses

App flipping

Buy under-monetized mobile apps, improve ASO and revenue, and resell at a multiple.

Catalog synthesis

The idea, in plain language

This business builds or buys simple apps, improves marketing, ASO, revenue, or positioning, and sells them for cash exits. Customers are app users while the exit customer is a buyer seeking a proven micro-SaaS or mobile-app asset. It takes fast product development, launch marketing, app-store or paid-ad skill, revenue tracking, and buyer negotiation; capital can be low for building from scratch but time discipline is required. The videos cite one AI cooking app sale, a simple app reaching $50K/month in four months, 17 apps built with two sold for $265,000, four app flips producing over $500,000, targets of $10-20K MRR before selling, and phone-flipping stories with $9M in profit that are adjacent but not app-specific.

Where the sources agree

  • Speed matters: the playbook is to ship small, test demand, and improve what gets traction.
  • Marketing and distribution are as important as coding the app.
  • Simple products can be valuable if they generate recurring revenue or clear buyer interest.
  • The exit depends on clean metrics, revenue proof, and a buyer who wants the asset more than the builder does.

Where they differ

  • Starter Story gives app-specific founder stories with concrete exit and revenue numbers, while Koerner mixes app selling with vibe coding, shortcuts, phone repair, and resale stories.
  • Some videos advocate building fast from scratch, while the idea definition is specifically about buying under-monetized apps and improving them.
  • Lotts Ezeike's playbook targets $10-20K MRR before an all-cash sale, while Nico's story is a portfolio grind of 17 apps and two exits.
  • Several Koerner examples are not app flipping at all, but they reinforce fast building, selling shortcuts, and flipping assets.
  • The numbers range from $50K/month app revenue to $265,000 in exits, over $500,000 from four flips, and $9M phone-flipping profit in a related resale story.
