Diverse businesses are an engine for economic growth and community empowerment in the United States. That’s a simple fact. However today, these business owners face significant challenges in obtaining the necessary capital to fuel their business growth. Our mission is to address this fundamental imbalance and expand access to capital and critical advice necessary to assure the survival, stabilization and success of the minority business community.

We’re building a network of partners, including highly successful diverse businesses, technology innovators and major corporations and financial institutions who share our goals, to help diverse companies obtain needed capital and advice more easily and on better terms than has traditionally been the case. We believe a level playing field is not only the fair thing, it’s the best outcome for society and the overall economy.

“Those that know more, have to do more. At Diversity Capital, we are bringing to bear critical financial and technical resources to assist in the rebuilding of the minority business community.”
