In this episode of the Pure Digital Passion Podcast, I sit down with Yannick Lefang — Founder & CEO of Kasi Insight, Africa's leading decision intelligence company — for one of the most intellectually rich conversations I've had on this podcast.

Yannick's path to founding Kasi is unlike almost any other founder story in the African technology biased ecosystem. Born in France, raised in Cameroon, trained as an electrical engineer at the University of Ottawa (cum laude), he spent over a decade in financial risk management at TD Bank in Toronto — before joining the International Finance Corporation to advise African banks on risk frameworks across East, Southern, and West Africa. That experience revealed a data gap no one had filled: Africa had no reliable, high-frequency, pan-continental consumer intelligence platform. So in 2017, he built one.

Today, Kasi Insight tracks consumer sentiment, economic signals, brand performance, and retail dynamics across 21 African markets — conducting 120,000+ interviews annually and generating 80 million data points. Their Kasi Index of Consumer Sentiment is distributed on Bloomberg and Refinitiv.

We cover his entire journey — from his grandfather's entrepreneurship lessons in Cameroon, to the Nortel collapse, the Lehman Brothers crisis at TD Bank, the Kasi founding story, and what it actually takes to build Africa's consumer data infrastructure from the ground up:
