This attitude is partly to be expected given the infancy of many tech companies, with leadership teams that show talent but lack big-game experience. It’s also clear that the industry has a big diversity problem. At some Silicon Valley companies, just 1% of engineers are black. Female representation in technical roles often hovers around 20%. Growing tech companies have too frequently hired for a ‘culture-fit’ mould of 20-something, educated white men: intelligent people, yes, but hardly worldly-wise.
