We received an email today from Flowdock that their product is end of life, we found this announcement online which was announced on 10th of November 2021.

It blows me away that they would not try and sell a conversion to something else... how does a company just give up on this sort of recurring revenue with no attempt to capture some of it in the process?

Another chat system going down, Slack wins?

I used Flowdock back in the day. It was excellend, did threading better than Slack and was nice and fast. Never understood why more wasn't invested into it. Maybe the backend code was a mess? Who knows, but definitely back in the day at least it was product wise a possible competitor to Slack.
