David Wilcox is a social change leader and the founder of ReachScale (www.reachscale.com), a purpose-built global network that is scaling innovative social enterprises as well as building networks and ecosystems to shift significant resources into sustainable models for solving the world’s most intractable challenges. Wilcox has been a high visibility advocate for how sustainable models developed by social entrepreneurs—those who are steeped in the actual problems and solutions—can be combined with underutilized resources and supportive policy changes to scale solutions that become fully sustainable. The Guardian has identified Wilcox as a top ten sustainability leader in America. ReachScale’s activities in India are driven by a clear understanding of the knowledge around scale that resides in the innovative social enterprises and NGOs in India. ReachScale advocacy highlights the importance this critical knowledge to real progress in solving the world’s toughest challenges. The direct corollary is that this desired progress, which was just canonized in the Sustainable Development Goals, depends on the rest of the world discovering this reality. ReachScale works with scaling social enterprises in India and globally to demonstrate scale success and move resources to sustainable models. With a dual interest in business and social progress, Wilcox has been a CEO, CMO and head of business development for a number of technology start-ups, consulting firms, think tanks and digital enterprises. He graduated with an MBA from Harvard Business School. He lives with his wife, artist Deborah Barlow, in Brookline Massachusetts.
