OptDuty [0] is ramen profitable in my place (like $1k per month) after 4 months from launching. Although it's still side project for me. Everything started from a Show HN post and one comment on HN. Majority of paying clients are from HN too. I started the project in May, and launched in August. And after 2 months I was thinking it's total failure, because target audience is too specific and my marketing skills sucks. But by keep talking to a few early users I finally managed to convince them to use the product and than paid for yearly subscription. [0] https://optduty.com/ https://optduty.com/
