Brian Halligan and Dharmesh Shah, co-founders of HubSpot, met at the Massachusetts Institute of Technology in 2004. For the next two years, they exchanged ideas on how the Internet could help small businesses. The Internet had changed the business landscape, they decided, so they built HubSpot, which designs marketing software that gives small businesses online exposure. In addition to growing the business at a breakneck pace since 2007, Halligan recently found time for more mellow pursuits and co-authored a book, Marketing Lessons from the Grateful Dead.
