I don't know Lyons, but I do know HubSpot, and everything he's saying tracks with what I've heard from other people. And not just people with the temerity to be old, but just with the misfortune to be able to read a social group and make some conclusions about it. The company is a culture mob, there is aggressive practice of neuro-linguistic programming all over the place (never mind that it doesn't work, of course), and the whole thing is notably cultish and terrifying, in a startup world where "cultish and terrifying" is part of the standard playbook in the first place.

I do not much like them, if that is not obvious.

What makes me a little bit sad is when I meet somebody who works there--it's Boston, if you are in tech circles you are going to meet HubSpot people--and they're bought-in hard enough to not see that the light at the end of the tunnel is an oncoming train. They hire a lot of good kids and try to kill them, or at least turn them into Dilbert-esque sodden gray rags, by the end of their second year. They're not the only company to do it, and not the only company to do it here in Boston, but they are a stand-out offender.
