Revolutionizing Surveys with WhatsApp: A South African Startup's Innovative Approach

In a world where traditional email or form-based surveys struggle to reach their audiences, a South African startup is leveraging the continent's most widely used messaging platform to revolutionize the way surveys are conducted. According to We are Tech, Tim Treagus, a young entrepreneur based in Cape Town, launched Yazi in 2023, a platform that enables organizations to design and distribute surveys directly on WhatsApp, transforming a simple conversation into a valuable source of data.

How Yazi Works

Rather than sending external links, Yazi integrates questions into a familiar WhatsApp interface for the respondent. Participants receive questions as a normal message, respond at their own pace, and the tool collects quantitative and qualitative data in a simplified web-based analysis interface.

Benefits of Yazi's Approach

According to its promoters, this survey method, which is closer to users' digital habits, improves engagement and representation, particularly in markets where messaging is ubiquitous. By facilitating access to populations often excluded from traditional methods, Yazi demonstrates how everyday communication technologies can bring opinion collection closer to the reality of communities.
