When you say it's "perfectly scalable", what are you using as your reference? That is, what other SaaS has $30/month pricing, especially one in a field as crowded as email and work messaging (i.e. Slack). Obviously, SH is far from having, or needing to have, a finished business plan, and it seems likely that the $30/user won't be the default offering or main breadwinner. But that raises the question of why that number is relevant in the first place when assessing SH's viability.
