The worst start -up I ever joined (and this is saying something!) had this problem that this article really describes well, of focusing on downside problems while in the upside phase. It looked like the founder insisting on literally 100% unit test coverage (the code would set a constant to 5 and the tests asserted the constant was set to 5), even while the product had literally no users (in fact the growing code base had never been run outside of test).

The founder was ex-Google so this also tracks with the article.
