What we do

Data Zetu helps communities to make better, more evidence-based decisions to improve their lives. Through partnerships and collaborations with local communities, Data Zetu works with stakeholders to build skills and develop digital and offline tools that make information accessible to everyone.

How we do it

We work with ordinary citizens in Temeke, Kyela and Mbeya to discover what matters most to them and what keeps them up at night. And together, we use data to arm their communities with the information they need to advocate for smart decisions and better approaches to tackle those challenges. As a result, we’re helping communities base their actions on accurate, accessible, and hyperlocal information.

There are three interconnected strategies to help make this happen:

Engaging with communities to understand how information can help them address local challenges. Developing digital and offline tools that help people produce and access actionable data. Help communities build skills in finding, cleaning, and working with data.


About our logo

dz_logo_schematicOur logo tells a story about our program. There are 14 segments, each representing one of the 14 wards whose citizens Data Zetu supports. The size of each segments reflects its population density, ranging from fewer than a hundred people per sq. km. to nearly 30,000 per sq. km.

These wards sit in three PEPFAR priority DREAMS districts – areas with the potential for most HIV resilience and reduction impact. Learn more about our target areas below.
