Building a technology start-up is never easy, but for Denise Walker, founder of Cape Town-based e-hailing service Caby, it has been a seven-year journey of perseverance, research and unwavering belief.
Speaking at The Insurance Conference Western Cape 2026, Denise shared how Caby was born not from a desire to build another app, but from months spent listening to drivers and understanding the realities of the transport industry.
Rather than copying existing platforms, Denise focused on creating a business model that works better for drivers. Caby was designed to keep more of the value generated by each trip in the local economy while giving drivers a greater share of the income they earn.
The road to launching Caby was far from smooth. After two years of development, the business paused operations for 18 months and nearly came to an end. It was the encouragement of a long-time business adviser and the backing of investor Patrick O’Flaherty that gave Denise the confidence and support to continue.
Safety has also been central to Caby’s development. The platform includes features such as verified rider and driver identification, trip monitoring, an SOS function linked to emergency contacts, and operational controls that help reduce driver risk in high-risk areas. While technology cannot eliminate every risk, Denise believes thoughtful design can make a meaningful difference.
At 72, Denise continues to lead the business, working alongside developers, investors and industry partners to refine and grow the platform. Her story is a powerful reminder that innovation has no age limit and that determination, combined with the right support, can turn an idea into reality.
