I make Beekeeper Studio, another open source db tool (although v different), we started charging for a pro version 2 years ago. Would be cool to connect! I can tell you what we did and what did and didn't work - Matthew (at) beekeeperstudio (dot) io
I need remote part/full time folks to help with the following:
============
Marketing / Growth
Write blog posts, email sequences, landing pages, ads, videos, etc. Must be comfortable with Markdown and HTML/CSS.
Goal: Help increase signups & conversions, reduce churn.
============
Support & QA
Test the application, respond to customer requests, help triage GitHub. Write automated tests. Opportunities to do other stuff like coding / marketing if interested.
Goal: Help our releases be rock-solid.
============
