The Massachusetts economy, supported by strong health and high technology industries, has been recovering faster than the overall U.S. economy. The October jobless rate (8.1%) fell to its lowest level in over a year - a full 1.5% below the national average - and the state has added almost 50,000 new jobs since January. For today’s post, I thought I’d put the spotlight on a small but vibrant segment of the Massachusetts economy: high tech startups.

Below is the top 10 startups with open jobs in the Boston area. The ranking is based on both the perceived potential of the company, and the breadth of job openings. A special thanks to Tom Summit, TalentGraphz founder and local job market expert, for his suggestions in producing this list.
