Pros

The product is going in an exciting direction and users genuinely love using it.

Cons

There's been a lot of change in the last few years but as much as we yearn for the good old days, the reality is that everyone has changed - not just Slack.

Pros

Slack is an incredible product. We have lost some key managers along the way but the team is tight and look after one another.

Cons

Having to work with core AEs as specialists. They have a very high opinion of themselves
