$90K Per Month From His Book Arbitrage Software

A story about Peter Valley 👇

Valley started out finding free or cheap books and flipping them for a profit 📚

Then, in 2015…

he turned this passion and money-making gig into a software, Zen Arbitrage, which scans Amazon for books listed under their typical selling price. 

In 2022, when he sold his business, Zen Arbitrage had 750 paid users and raked in $90,000 in monthly revenue

Perhaps an opportunity there to build similar software for other niches on Amazon.

Or for other big marketplaces, such as eBay, Etsy or Poshmark 👀

A killer app could be one that does this for event tickets, scanning platforms like StubHub or Ticketmaster to identify underpriced tickets that could be bought and flipped (where permitted).

What other arbitrage opportunities could you help people take advantage of? 🤔
