Well, you're in luck! The entire presentation -- Brian's discussion about inbound marketing, Dharmesh's tour of HubSpot 3, and lots more -- is in the video below. You can also skip to certain parts of the keynote using the links following the video.
HubSpot 3 Announcement: Brian announces the launch of HubSpot 3, an entirely new set of HubSpot tools that, together, make it easy for mere marketing mortals to achieve the kind of personalized marketing (content + context) that Amazon is known for.
How HubSpot 3 Makes 1+1=3: Dharmesh explains that, like the iPhone, the magic of HubSpot 3 is not in its individual features, but in the possibilities that open up when all of its features are offered in a single, integrated tool.
