From what channels did you gain the most initial traction? After reading your other comments, I assume you didn't do "traditional" sales such as cold calling/emailing, so I'm curious as to how you built up a user base. I'm currently struggling to do that exact thing with my own business right now. I started selling (cold calling/emailing, demoing, PH/HN/IH posts, etc.) Jan. 1 2018 and I feel like there's something I'm missing as far as my sales process.
I did an interview for Indie Hackers with some detail (https://www.indiehackers.com/businesses/dependabot) but the short answer is cold sales was how I got started, followed by piggybacking off of GitHub's new marketplace.
I can't stress enough how valuable (from a learning perspective) sales was for Dependabot, but only after I started targeting the right people. For Dependabot that was commenting on open-source dependency update PRs (that people had created manually).
