About Us
Our Story
DIFFvelopment was born during a monumental period of underemployment and aggressive student loan repayment, directly following the founders’ graduations from some of the world’s top institutions.
“Frustrated with feeling completely unprepared for all of the financial strain we were experiencing post-college, we began to research what we were experiencing and came to find that our situation was representative of a larger endemic issue. This motivated us to begin exploring possible solutions.”
– Esi Kagale Agyeman Gillo, CEO & Co-Founder
As young Black graduates, we started DIFFvelopment because we could not believe that after earning undergraduate and masters’ degrees from some of the top academic institutions in the world, we faced so many unforeseen employment and economic challenges. As perfectionists who pride ourselves on excelling, it was devastating to feel so behind in the race to attain commensurate employment, achieve financial security and simply do what we wanted to do without having to sacrifice so much every step of the way. It became clear to us that even with education, the legacies of slavery and colonialism that ensnare the Black race still play a major role in dictating our quality of life and ultimately what we are able to accomplish.
Our shared experiences of underemployment and unemployment, motivated us to explore the core causes of the issues we faced and develop programming that would prepare Black college students for Black life after college in a way that has the potential to shift the trajectory of Black economics and cycles of Black powerlessness for generations to come.
We envision a world where Black people know their history and view themselves as part of a collective global community that is empowered and responsible for identifying, defining and solving its own socioeconomic issues through visionary entrepreneurship, wealth building and philanthropy.
