I don't get it. According to the blogpost, 450,000 organizations use Airplane, and over 50% of Fortune 500s are paying customers? Okay, that suggests a viable business. And then they're shutting down?

Normally you'd expect to see some layoffs and a paring down to profitability: it is SAAS, after all, so you'd expect high gross margins that could be operated by a skeleton crew if necessary.

I'm wondering what happened here -- was Airplane gross-margins negative? Was there some fundamental issue that was unsurmountable? In my mind, it's just kind of strange for a popular and widely used, evidently saleable product to wind up burning through all their runway and then ending in what looks like an acquihire. Odd.
