This article doesn't inspire much faith in me as a reader. The first example of a start up beating a tech giant is Snap competing with Facebook. Snap did well for a while, but things are looking grim last I heard. Likewise, the author, in the comments, suggests that the big three priorities of Amazon are AWS, Groceries, and Prime. Seems to be forgetting the two largest categories of Amazon's business - foreign and domestic retail markets. Omissions like that make question the rigor of the analysis over all.<p>Speaking of being able to focus on three things, why? Why that number? Isn't Amazon, for example, competing in Cloud computing, e Books, retail, tablets, content, groceries, home assistants, advertising, and probably a few other major categories? Likewise Microsoft has game consoles, office, cloud offerings, Windows, search, and again, other areas.<p>I think the thesis, that you can compete with tech giants, is true, but the analysis of the article is brief and poor. The reason you can compete with tech giants is because they are looking for a way to grow their gigantic companies and so they will forgo relatively small markets even if they are promising. I would not bet on your startup to beat Amazon in making budget tablets, or Apple in making premium ones, but if you can identify a niche with a customer that needs to be served you can outcompete major companies because they won't be willing to focus on that niche.<p>For example, you can't make a better budget or premium tablet, but maybe you make a tablet that floats to serve fishermen. It's a hit, so you work on connecting it to their fish finders, now you're building custom sonar sensors because your brand has a reputation and you want to add features to the tablet. Before you know it, you have a self-driving boat, and you're entering the shipping market automating the work formerly done by seamen. With a big presence in shipping you use your connections in China to start up your own retail website, and now you can compete with Amazon directly because you can arrange cheaper shipping of goods from China to US marketplaces.<p>I also do think there is some validity to the article's point that you'll be competing against the C team. I'd add on to it that as a startup you'll be more agile. If you're competing against a tech giant they'll be held up by a lot of bureaucracy that won't afflict you. You can match their dev team for competence, move faster, and compete in spaces where they won't want to follow. That's how you won against big companies, not because they are magically limited to paying attention to three areas.
