A new chapter is being written in Tanzania’s education sector as Nancy Sumari steps into the spotlight as a technology-driven changemaker. Known globally as a former Miss Tanzania and Miss World Africa, she now commands attention for her work in inclusive education and digital innovation.
Sumari has shifted her focus from pageantry to purpose. She says her mission has always been rooted in teaching and working with children. However, her global exposure helped refine that vision and gave her tools to expand her impact across Tanzania.
Her flagship project, the Kalimani app, is gaining recognition across Africa’s edtech space. The platform supports deaf and hard-of-hearing learners through animated sign language and structured curriculum content. As a result, it is bridging a long-standing education gap in classrooms.
Recently, the innovation secured the prestigious Zero Project 2026 Innovation Award. This recognition highlights the app’s growing influence in advancing inclusive education through practical technology solutions.
Sumari explains that her idea emerged from years of volunteering in primary schools. During that time, she observed that children with hearing impairments lacked adequate learning tools. Consequently, she focused on building a simple and scalable digital solution for both schools and homes.
Today, the Kalimani app operates in more than 35 schools across Tanzania. In addition, developers are integrating artificial intelligence features that convert written text into sign language. This advancement is expected to further improve accessibility and learning outcomes.
At the same time, Sumari continues to navigate the demands of entrepreneurship and family life. She admits that balance remains a daily challenge. Still, she relies on strong support systems and resilience to manage her responsibilities effectively.
Meanwhile, she has raised concerns about increasing online abuse. She urges individuals to practice kindness and accountability on digital platforms. According to her, online behavior often reflects deeper societal values shaped at home.
Despite her demanding schedule, Sumari maintains a connection to music. She participates in choir singing, which helps her relax and stay grounded.
Her journey reflects a broader shift in Africa’s leadership landscape. More innovators are now focusing on impact-driven solutions powered by technology. In Tanzania, Sumari stands out as a leading voice in this transformation.
As education systems across Africa evolve, platforms like Kalimani continue to gain relevance. They not only improve access but also create equal opportunities for underserved communities.
