We used Mixpanel in the past but it turned out to be a bit expensive for our needs, so we moved everything to Google Analytics. It is harder to set up event tracking with it, but not impossible and it is free. We actually wrote about it here: https://www.authorea.com/122946/VMmuoE2vxQQEnG-Ax2GNBw
We use Pipedrive as a CRM. It’s a good tool for our needs which are very limited. We mainly use to keep track of our leads which are Universities and Research Centers. We tried other tools in the past but this is perfect for our needs right now.
We use Authorea, our own platform to write and market content. While Authorea is focused on scientific and technical content, we are planning on moving towards content distribution, content creation and publishing so it makes sense that we write our own content on our own platform!
We like Stripe, but they have a very minimal offering. If you want some more services, you have to use other tools on top of it like Recurly. Stripe’s API is really good, but I wished they exposed more of it on the UI/dashboard as you need more data to do financial analysis on it.
Intercom unfortunately works very well. I say “unfortunately” because it is a pretty expensive tool but we completely rely on it and no other tool has such a complete integration with our product. We are happy with it, but it is definitely the one tool we spend most on.
Gusto works fine. It is a very simple tool. As far as I know, they are expanding to also manage benefits, vacation days etc., but for now it is very basic and it accomplishes our needs.
We decided to approach project and product management both in a technical way. We settled for GitHub Issues and GitHub Projects (which is a brand new feature of GitHub), as our team of engineers did not want to have to use yet another tool. We were all already familiar with GitHub.
