It took more than 1 year, but I'm finally done building the minimum viable product for Plumm. I worked mostly nights and weekends. I coded the whole thing in Python and JS. This is my side project, but it is fully functional and stable product, which you can use right now.
I've built Plumm, because I wanted to chat with customers and my team members in one place (one tool). Using separately livechat, email accounts and Slack was not perfect for my communication needs.
I'm excited to start talking to customers and see what they think about the product so far!
