Hey all,
Always sad to see good products shutting down. Also a bit frightening as I'm about to enter this same market, hehe.
I want to mention what we're building in case anyone looks for alternatives in this thread.
It's called GitSpeak and it's a project management tool which prioritizes developers first. Our goal is to create a PM tool that devs actually enjoy working with, and which saves them time rather than eat time.
Some of our features include multi-repo views, boards, a rich text editor and a neat screencasting option for code reviews, docs, and onboarding. Plus, we are going to be the fastest one out there (we're using Imba.io to build the tool btw).
Check it out here if you're interested:
