Surprised this doesn't mention meticulous.ai, who seem to spam HN with "we're hiring!" each month but i've never heard of anybody using them, nor do LI show any new employees. Hey Gabriel, what's going on?
I don't think the continuous hiring posts are anything other than a sign that it doesn't cost them anything and they get good leads every time they do it.
What you are describing here just sounds like one of their portfolio companies taking full advantage of one of the perks that comes with YC? I don't know what the limit on the "We're hiring" posts is for portfolio companies, and I also have a few on the top of my mind that showed up a lot, but having that as "ads" on this website isn't too bad.
A half-decent Schemer in found3rm0de would've built 5 failed MVPs and exactly one unicorn in that timeframe.
