I've known Iyinoluwa "E" Aboyeji since he was an aspiring, 19-year-old entrepreneur. Today, he's the founder of two African unicorns, Andela and Flutterwave — the latter of which is now the continent's most highly valued tech startup at over $3 billion. We discuss the challenges he overcame, plus those that remain, and why he's bullish on Africa's future. As the general partner and co-founder of Future Africa, "E" now invests in over a hundred African startups. He shares strong opinions on the cultural differences between Nigeria and the U.S. — and the unique positive aspects we can learn from each society.
