It might be a bit egoistical, but this makes me feel better about my project going at a snail's pace (after 6 months I have something barely resembling an MVP).
Growing slowly has aided me hugely in being able to refine and optimise as I went. If I had the money to throw at marketing 2 years ago, to get loads of eyeballs on the site, it would have failed. Because the product wasn't ready then. It's been 2 years of listening to feedback and making incremental changes that has allowed me to really start growing revenue this year.
Getting first users was really tough. I "launched" on product hunt and that was a bomb. I posted around some forums and that got some attention, but it was a post on reddit that was seen by the owner of a niche forum for audio engineers that helped.
He allowed to me to post in their commercial thread and that got me going with a bunch of audio engineers who saw real value in the product.
That burst of interest and Q&A gave me a TON of feedback to improve things and add features.
Then things just VERY slowly started to snowball. and I do mean VERY SLOWLY.
I also get a lot of traffic from organic google searches as I rank number 1 in google for some very relevant search terms. Even outranking soundcloud. Have no idea how that happened.
As far as I'm concerned it was 2 years of refining the product. Only in the past 6 months have I seen consistent month on month growth, and it's still very early days.
