Mass Medical Angels is a VC fund in Boston focused on Health Care and Biotechnology. Mass Medical Angels (MA2) was founded to answer the need for a dedicated life-science centric angel group in New England. The Boston area is a world-leading supercluster for medical innovation, but all early-stage companies in the field have tremendous difficulty with first round funding. Their goal is to provide money and mentoring to the lifescience community to achieve superior returns for their group, and more clinical innovation for the community.
