Wellth, a digital health company utilizing behavioral economics to empower people to prioritize their health, today announced an oversubscribed Series B fundraising round of $20 million. The round was led by SignalFire, with participation from Frank Williams, Co-Founder and Former CEO of Evolent Health (also joining Wellth as Chairman of the Board), and existing investors The Social Entrepreneurs’ Fund, CD Venture, Yabeo and Partnership Fund for NYC. Wellth has achieved impressive annual growth since its founding in 2014 due to its proven ability to connect with members and engage them more effectively to influence behavior change—such as taking medications as prescribed. The new capital will enable the organization to further invest in the behavioral science engine behind the app and in team expansions to support Wellth’s growing member base.
