Sermo, a Cambridge, Mass.-based online community created for physicians, said it has raised a $9.5 million second round of funding.

The round was led by new investor SoftBank Capital, with additional funds from existing investors Longworth Venture Partners who initially funded the Company. The site launched in September 2006, and appears to have grown quickly.

The company says almost 6,000 doctors from all 50 states in over 30 different specialties have joined the medical forum to share insights, learn from each other’s experiences, discuss patient care.

It says the Sermo community is increasing by 400-600 physicians every week.
