Nairobi, Kenya | October 2026

ONE Data is pleased to welcome Tosh Juma as its new Head of Global Operations, marking an important step in strengthening its presence in Africa and deepening its connections to the continent’s growing technology and innovation ecosystem.

As part of The ONE Campaign, ONE Data works to make data more accessible and useful to leaders making decisions about public resources. With Africa central to this mission, its ambition is not only to provide African decision makers with world-class data, but to build closer relationships with the institutions and technology communities shaping the continent’s future. By becoming more embedded in East Africa’s innovation ecosystem, ONE Data aims to draw on the ideas and approaches emerging from the region to strengthen its work globally, while ensuring its products respond to the realities of those they are designed to serve.

Tosh brings more than 15 years of experience building and leading organisations across Africa, with a deep understanding of the continent’s diverse social and economic realities. Grounded in human-centered design, his work has focused on understanding complex challenges through research and collaboration with communities, and developing solutions shaped by local contexts.

His career spans leadership roles in design, strategy and innovation across Africa. He previously served as Managing Director for Sub-Saharan Africa at IDEO.org and Regional Lead at Dalberg Design, where he helped establish and grow both organisations’ regional operations. He also founded and led the Nairobi Design Institute and, earlier in his career, helped establish iHub, East Africa’s first innovation hub as a Founding Manager.

David McNair, Managing Director of ONE Data, said “Our ambition at ONE Data is to radically improve the insights that decision makers, particularly in Africa, can access so they make better decisions that improve people’s lives. Tosh’s deep experience in design thinking will help bring us closer to the problems African institutions are facing so we can design the best solutions, while bringing African innovation and tech expertise to our global mission.”

On joining ONE Data, Tosh said “Some of the most important insights come from understanding people’s everyday realities. Too often, the challenge is turning what we know into decisions that genuinely improve people’s lives. I’ve spent much of my career working alongside communities to understand the realities behind the numbers and build solutions that respond to them. At ONE Data, I see an opportunity to help close that gap at scale, bringing data and lived experience closer to the decisions that shape how public resources are invested and whose needs are prioritised.”

In his new role, Tosh will work closely with David McNair and the wider ONE Data team to advance the organization’s ambitions, helping strengthen its impact and expand its reach. Based in Nairobi, he will also play a key role in deepening ONE Data’s engagement and partnerships across Africa, bringing his experience working with communities and institutions to support its continued growth.
