And before HipChat there was (and still is) Flowdock [0]. I think they have the best threading model I've still seen on chat apps, so it was very weird seeing Slack get threading so wrong when there were much better examples to copy from. I suppose Slack won that popularity race as they had a free tier; AFAIK Flowdock was always only available for a paid subscription. Slack definitely was for a long time the worse product. Though at some point much later Slack's larger dev budget finally tipped the scales in their favor I think.
