Khethi Ngwenya built SchoolMedia, a school-based advertising and community upliftment company, around a simple idea, brands get access to a hard-to-reach youth audience, while a share of the advertising revenue funds real resources for the schools themselves.
A business model built on shared benefit
SchoolMedia secures advertising rights across thousands of schools nationwide, letting brands run campaigns, health messaging, bursary information, sports promotions, on school walls, boards and other spaces, with a portion of that revenue going back into the schools as equipment, signage or other resources the school actually needs. Ngwenya’s insistence that every campaign benefit learners directly, not just the paying brand, has remained the core differentiator of the model since the company’s founding in 2010.
Starting young and staying focused
Ngwenya launched SchoolMedia at 19, after an entrepreneurial journey that started at 12 with a small fireworks business funded by a loan from his mother. Being taken seriously as a young founder without an established track record was a genuine early obstacle, one he addressed by consistently delivering results rather than trying to argue his way past scepticism.
What the model demonstrates for other social-impact founders
SchoolMedia’s growth, now reportedly generating around a million dollars in annual revenue and continuing to expand its school network, shows that a business model built around genuine mutual benefit, not just extracting value from an underserved market, can scale sustainably. For founders building in youth-focused or community-facing sectors, the lesson is that a credible social-impact angle works best when it’s structurally built into the business model itself, not added afterward as a marketing layer.
