Despite the economic turmoil, venture capitalists have supplied a third round of financing for a company that helps health plan members become better care consumers.

Kleiner Perkins Caufield & Byers L.P., Menlo Park, Calif., and other firms have invested an additional $15 million in RedBrick Health Corp., Minneapolis, according to RedBrick.

RedBrick develops health programs, advocacy services, and other services designed for self-insured employers that want to encourage health plan members to improve their own health and shop for health care services more effectively.
