Founder John Samson, left, and his partner Dan Gill run SpeedDateUSA.com, a company with national reach, that hosts events for people with similar interests, from romantic to social and business as well. Samson says speed dating was popular in New York City and Europe when he moved to Philadephia a few years ago and saw an opportunity to start a business here. The ten to fifteen guests who sign up for an event meet one on one with each other for 6 minutes before rotating to another guest. What started as a service for lonely hearts now uses a similar concept, speed networking, to bring together investors looking to network with one another and even caregivers looking for nannies. Interviewed near Dan's office outside the old Solaris on Germantown Avenue in Chestnut Hill.  Watch video here.
