Simple Side Project = $300,000 in 3 Years

Sachin Neravath
  • Sachin Neravath

  • Founder of lightGallery
  • $300,000+ revenue

💬 Sachin Neravath tweets about his side project…

3 years ago, I started my indie hacking journey with a simple Javascript library and it crossed $300K in revenue.

The library is lightGallery

A lightweight, modular, JavaScript image and video lightbox gallery plugin.

📈 In terms of growth…

I don’t do anything special for the distributions. 

All the traffic comes from Google. So, I worked a bit on SEO and free tools. Thats it

Asked if he could go back 3 years and give himself one piece of advice, Sachin replied…

Focus only on one main project

lightGallery looks good, but also fairly simple.

I’m amazed Sachin has made $300K from it, especially with one-time fees for licenses 🤯

I would have guessed there was no market for this 3 years ago, that a good solution already existed. 

My takeaway: worth doing keyword research around your expertise and seeing if you can build something along those lines 👍
