I was reading an article by an American founder yesterday about reindustrialising the US and “leapfrogging” Shenzhen(China). She shared a graphic which mapped out the five layers of Manufacturing, from materials to finished product, and identified prominent US companies at each level( both incumbents and startups/industry challengers), with the aim of showing how lower level manufacturers supply the materials and components that higher level manufacturers need to build their own products, and identifying where the biggest gaps where. I found it interesting and decided to do the same for Nigeria’s hardware manufacturing industry. After a fair amount of research, Here are my results. Note: This list of companies is not exhaustive. I focused on those with more verifiable products and manufacturing facilities.
