Join us! On August 1st,
WJF becomes  
Mentor Capital Network! 

We invite YOU to be a part of it.

Chances are you know the William James Foundation (WJF) through our Sustainable Business Plan Competition. Over 11 years nearly 1,000 volunteer mentors have donated $3 million of mentor capital to more than 800 for-profit social enterprises. The result: over 450 for-profit enterprises have been launched, creating thousands of jobs and impacting millions of people. 

However, WJF is not about competition. Just the opposite. Its about astounding collaboration between mentors and social enterprise creators. It's the investment in expertise that defines WJF. The skills and knowledge this network of people share is something we call mentor capital. Hence our new name.

Meet Mentor Capital Network. We are a network of people who build, manage, invest in, research and support for-profit multi-bottom line businesses. 

Join Mentor Capital Network. We invest skills, perspectives, experiences and expertise to help inventors, innovators, next generation, and early-stage companies build successful business models and scale their social, cultural and/or environmental impact.
