We sold one week plan first time!

Today I want to share with you guys our next big milestone. We sold 7 days plan for Numbro (https://www.numbro.com/). We prepared a really good offer for being displayed on the top of the feed. Patience paid off. It's another plan sold without any promotion. We are so happy that Owwly is gradually progressing and clients like Numbro remind us to keep going.
We would like to help side projects and startups promote themselves and give them tools to do it more efficient. Could you tell me what's the biggest pain point when you trying to promote products? Is it money or limited number of services which empower that?
