Many Nigerian businesses do not struggle because they lack market opportunities, strong products, or talented people. Their biggest challenge often emerges when the structures that helped them achieve early success become inadequate for managing growth. Adeolu Adewumi-Zer, founder of ZER Consulting Africa and former Managing Director/Chief Executive Officer of Allianz Nigeria, argues that many companies remain trapped by founder-dependent systems that limit decision-making, weaken accountability, and create succession risks. With more than 25 years of experience across Africa, Europe, Asia, and the United States, Adeolu has worked with organisations on strategy, transformation, governance, and organisational development. She is also the author of Afro-Optimism Unleashed, which reached No. 1 in the United States and was shortlisted for the BCA African Business Book of the Year. In this interview with Kenneth Athekame, she examines why Nigerian businesses struggle to transition from entrepreneurial ventures into scalable institutions, why governance becomes critical as companies grow, and how leaders can build organisations capable of thriving beyond their founders. Excerpts:
Many Nigerian businesses have strong products, capable employees, and market opportunities but still struggle to scale. What explains this growth ceiling?
In many cases, the challenge is not the market; it is the organisation itself. Businesses often grow faster than the systems supporting them. A structure that works for a small company can become a constraint when the organisation expands. In the early stages, founder involvement is often an advantage because decisions are faster and everyone is closely aligned. However, as the company grows, the same model can slow execution. When a business has hundreds of employees, multiple product lines, or operations across different markets, decision-making cannot continue to depend on one person.
Companies that scale successfully understand that growth requires redesigning how decisions are made, how accountability is established, and how leadership responsibility is distributed.
