Zulip is still the best solution to the problem that I have encountered. I used it for my startup for a year or so. Not currently using it unfortunately. I have heard some people have difficulty getting people to use topics properly (i.e. not putting everything in one topic), although we didn't have that problem. Possibly its an uncanny valley issue - it's too close to Slack/WhatsApp and so people just slip into that habit. I could see that something like Braid which feels very different could force new behaviours to be created.
