About Purposeful Ventures
Purposeful Ventures partners with social entrepreneurs and philanthropists to improve the education and well-being of young people from their earliest years.
We define and diagnose the issues affecting children and young people, analyse evidence and explore the most promising solutions. We then select, accelerate and, where we find a gap, incubate organisations which tackle those issues. We offer more than just funding to our charitable organisations. Our expertise, operational experience and networks enable us to deliver tailored, hands-on support with a relentless commitment to system change.
