Customer support teams would, easily, to manage shared inboxes. Competition includes Salesforce Desk ($75/mo), HelpScout ($35/mo), Zendesk ($89), and so on.

And if Front's shooting for the broader business email market, well, you have Superhuman ($30/mo) at least closer to that price range.

Lets say you have an engineering employee with a base salary of 150k. His total cost to the company when you factor supporting roles is perhaps 300k. Assume this person needs to generate 2x that in value for the company, so lets say 600k a year. So that's 0.01% of the job he needs to do. If the tool is even somewhat useful that seems like a very fair price.

I am not sure how an engineering employee with a base salary of 150k would eventually cost 300k and why a customer should pay for that engineer to make 2x his pay for the investors gluing a couple of 3rd party APIs and making a dashboard.

Comments like these are a great reminder of how disconnected HN comment section can be from reality. That pricing is nothing.

At that price, if it helps close 1 incremental sale a month per seat it pays for itself.
