A friend recently pointed me to a July study by Oliver Wyman titled Assessing the Impact of Big Tech on Venture Investment. I was immediately intrigued because this is a question I’m asked all the time and one for which I don’t have a good answer. On the one hand, I see how platform giants could expand startup activity because they seed an ecosystem, improve labor quality, and provide capital (as customers, investors, and acquirers). On the other hand, I see how their sheer dominance—and the ability to leverage their power into adjacent markets by favoring their own content or wares—makes it difficult  to compete in their space. In fact, reporters have told me that most VCs won’t touch startups operating anywhere near these companies’ orbits, a phenomenon that is apparently so common it’s been given a nickname: “kill-zones”. I took a close look at the numbers to try and figure out what’s going on.
