Recently finished Peter Thiel's Zero to One . Found it very useful for examples of massive US-centric growth companies, but not very useful for business growth in Africa. However, it did highlight for me the problem I've been facing with Lateral Labs - there is a really difficult area in between Day 1 of a Sole Proprietorship and Day X of a Limited Company with investors. That is, growing a company to a level where it can consistently sustain itself (people and everything else) as well as turn a profit. Not all Sole Proprietorships make money, but even fewer make enough money to stop relying on the founder.
