About
UnaMesa Association
The UnaMesa Association is a 501(c)(3) public charity formed in 2006 under the leadership of Greg Wolff following a fellowship at Stanford University in the Reuters Digital Vision program for Social Entrepreneurs. A Silicon Valley technologists with deep expertise in machine learning and psychology, Greg recognized two fundamental challenges for social innovations:
- Silicon Valley does a terrible job of creating innovations in healthcare, education and social services because markets (and therefore Venture Capital) does not value community or relationships.
- Secondly, smart, dedicated, skilled entrepreneurs who identify a social need and promising solution often fail because they expend all their time and energy starting a non-profit and raising money before they can demonstrate value in the real world.
UnaMesa provides a fast track for social entrepreneurs to put their ideas into practice. Success is measured in strengthening communities and creating caring interactions with scalable innovations. In the long run, UnaMesa and our network of innovators seek to catalyze a new approach to valuing relationships and meaningful interactions -- enabling an ecosystem of innovations driven by Social Capital that operates on par with the transactional world of Venture Capital.
