This page, does not really follow "Conserve attention at all costs" when there's a 4x7 pricing grid with confusing information scattered about it. The rest of hubspot's design is equally banal, perhaps the author has some other role in the company than design?
I'm not a fan of complicated pricing schemes, but the existence of one has nothing to do with design in the vast majority of companies. That's a bizdev/sales/exec thing dumped on the designer. Assuming that what information has to be displayed there is immutable, I think the design you point to does it about as well as it could be done.
Having said that, I would agree with anyone who said that the site feels a bit too template-derived in the way that many startup sites post-twitter-bootstrap do, but OTOH it is a fairly well executed template design.
A Google image search for 'Performable' turns up lots of screenshots.
Having said that, HubSpot has spent a lot of time on designing our pricing model (vs. the pricing page).
For our first 2 years, HubSpot had a single price ($250/month). We've since run many, many pricing experiments and though the complexity bugs me sometimes, it's working.
But now that this thread is going, I think there are things we can do the improve the pricing page (even if we leave the pricing model the same).
As for the website, I really like it. I don't find the grid confusing at all. The pricing should be simpler but the designer is not responsible for that.
