Hey there!
Thanks very much, I appreciate the kind words. Right now, we're in early access where we're partnering with companies for feedback on the product so we can make something that people love.
As such, our pricing is pretty simple — we charge based on the number of Slack users in your workspace, and put you in a bucket. For some companies, that doesn't work as well (e.g. if 95% of your company is customer support agents that would never use the tool), and we change it as appropriate. Basically, we'd rather optimise for feedback and love than for revenue at this point :)
