I’ve always wondered about building a startup on another startup’s back. What happens if they cut you off? Is getting bought up by Slack the end goal here? Seems like a big risk, one whim at Slack and you’re toast.
IMO what makes Slack so power is their app ecosystem. We aren't too worried about them shutting that down or competing with us. We see the awesome folks on the Slack Platform team continue to invest heavily there.
But if Slack wants to seriously compete in this space we'd welcome it. The more attention and competition the better. Most accounts we approach we've found they didn't know off the shelf solutions existed!
