Turning a Weekend Side Project into Full-Time Income

The Side Project

I built a Chrome extension to solve my own problem - managing research bookmarks.

  • Total time: 2 weekends
  • Tech stack: Vanilla JavaScript
  • Cost: $0

I wasn't trying to build a business. I just wanted to solve my own problem.

Unexpected Growth

Shared it on Reddit. 1000 installs in the first week. The comments were overwhelming:

  • People asking for features
  • Offering to pay
  • Requesting custom versions

I realized I'd accidentally found product-market fit.

The Transition

The growth timeline:

  • Month 3: Added a pro plan ($5/month)
  • Month 6: 200 paid users, $1K MRR
  • Month 12: Quit my job, 800 paid users, $4K MRR
  • Month 18: $8K MRR with 1600 customers

Each milestone felt impossible until it happened.

Keys to Success

What made the difference:

  • Solved a real problem that I had myself
  • Started small and simple - No complex features
  • Listened to users obsessively - Every email got a response
  • Kept my day job until it was safe to quit
  • Saved 12 months runway before making the leap

Life Now

I work from anywhere, set my own hours, and love what I do.

It wasn't overnight, but it was worth every late night and weekend spent coding.

"The best time to start was yesterday. The second best time is now."
