Verified access between Silicon Valley and Africa
Meet the people who can move your work forward.
Silicon Xchange is a trusted network of founders, investors, and operators working across Silicon Valley and Africa.




Why Silicon Xchange exists
Good companies are missed when trust depends on who already knows you.
Founder
Can have real revenue and still look like a stranger to an investor in California.
Diaspora executive
Can have the right expertise and no reliable way to tell which founders are ready.
Investor
Can want exposure to African technology and still lack the company-level information needed to act.
Warm intros
Help, but do not give the market a repeatable way to verify people, compare opportunities, and build trust.
That is the gap Silicon Xchange closes.
Results
Real outcomes, not a longer contact list.

From introduction to international customer
Silicon Xchange connected ChipMango, a semiconductor talent and engineering company, with a university in Uganda — turning a cross-border introduction into ChipMango’s first global customer relationship.

Finding the technical leadership to scale
Through the Silicon Xchange network, Satlyt connected with the technical leader who would go on to become its CTO, helping the space computing startup build the engineering leadership needed for its next stage of growth.

A new path for Kenyan founders
At the 2025 Silicon Xchange Summit in Nairobi, Dr. Tonny K. Omwansa, chairman and president of the Innovation Agencies in Africa Network, and Nick Vilelle, founder of the Nairobi Business Angel Network, joined Silicon Xchange and ecosystem partners working to bring Kenya into the Startup World Cup circuit.
BuuPass went on to become the first African startup to place in the global Top 3.

Bringing OpenAI directly to African developers
Through Build Hours with OpenAI, Silicon Xchange gives developers across Africa direct access to OpenAI engineers for hands-on technical sessions focused on building and shipping production software with AI.
The first session drew nearly 200 developers from 18 countries, with more than 430 registrations across the series.
What people say after entering the room
The difference is intentional.
“Most convenings put the right people in a building and hope. This one engineered proximity, and you could feel it in the quality of what got said. Investors, operators, founders, builders, every seat carrying real weight.”
“An excellent gathering of like-minded individuals and inspiring conversations about the future of FDI on the continent. Fantastic work from the Silicon Xchange team.”
“Easily one of the highest-quality events yet. Thumbs up for the organizers.”
