I'm a frontend engineer and I came up with an idea a long time ago. I was working at FB at the time and worked on the project part-time, on weekends. I wasn't able to openly promote my product, so I kept quiet. Thinking that when I leave, I can easily promote a my product.

Fast forward to now, I have a fully featured product with almost 0 users. My competitors have thousands using a less feature-packed product. I don't understand how they manage this, while I can't get even a few people to sign up.

What can I do in order to grow? When I share my product, people ask "Is it like X?", when I objectively was the 1st one to start building.
