About us

Celebrating entrepreneurship and economic empowerment is at our very core. We aim to redefine entrepreneurship beyond a few bros in Silicon Valley working on tech start-ups to include people that look like the rest of us.

Our community

The FounderTribes digital community provides founders with access to other founders and early-stage investors relevant to their sector and stage. The tribe includes founders, mentors, coaches, and venture capitalists, all committed to creating a global community for entrepreneurs who are overlooked and underestimated. They join us in our work to level the playing field while diversifying investor portfolios, boosting economic growth worldwide.

Our team is comprised of genuinely gifted minds

We have assembled a talented and diverse team and board. It is a team of entrepreneurs, teaching entrepreneurs, whilst working in an entrepreneurial and innovative start-up. We really live and breathe this stuff.

All our team members are deeply passionate about entrepreneurship, having either founded or led start-ups before. Our Tribe includes expert developers, serial entrepreneurs, ex-CEOs, COOs and even a shortlisted US vice-presidential candidate.
