I can't imagine many companies that would rely on that - an unknowable future cost in the budget, with only a month migration warning if you can't afford it is not a reasonable proposition.
I mean, yes, pre Ramen profitability, saving every cent matters. But there are already calendars, chats, VC apps in the free space that are more likely to stay around than a startup without income.
I wish Pesto success, but I think they'd be better off setting a price soon.
Yeah I imagine they're still building and experimenting - and early adopters should treat it as such.
Better to set no price rather than guess incorrectly and advertise the wrong price.
