Vistage member company CareTree accepted into MATTER membership

San Diego, March 1, 2015—Vistage member company CareTree was recently one of ten health care technology startups accepted for membership into MATTER, a 25,000-square-foot accelerator slated to open in January and aimed at growing next-generation diagnostics, biopharma, health IT and medical device businesses.

CareTree is the developer of a centralized, coordinated health record that is used like Facebook. Patients, caregivers, families or providers create a patient profile and invite others to access it. CareTree president Brian Brammeier has been a member with Vistage since 2015.

Steven Collens, MATTER CEO, said, “The diversity of their technologies is representative of the community we are building at MATTER, which also includes industry leaders, research institutions, health systems, physicians and investors.”

MATTER is a community of healthcare entrepreneurs and industry leaders working together in a shared space to individually and collectively fuel the future of healthcare innovation. MATTER’s mission is to proactively connect and promote collaboration between entrepreneurs, scientists, physicians and industry partners in order to bring next-generation products and services to market that improve the quality of care and save lives.

MATTER is a not-for-profit organization developed by a team of entrepreneurs and industry leaders. The state of Illinois supported MATTER’s creation with a $4 million investment. ChicagoNEXT, Mayor Emanuel’s council on technology and innovation, is a key development partner.
