HubSpot continues on with a press push this week considering they’re raising a big round right now with Sequoia Capital at their offices yesterday. They also announced  partnering with social CRM software SugarCRM yesterday. Today they released growth numbers, the big one in the title being that they now have 4,000 business clients.

Other 2010 growth stats:
-500 new customers in the last 3 months
-Over 4.5 million leads generated by customers using HubSpot since its founding in 2006
-Almost 100 new HubSpot employees in 2010

Other news: They are now organizing meetups called “HUGs” (Hubspot User Groups) in cities so marketers can meet one another — and hug it out.
