Honestly reads more like a "Handbook for the CEO of a startup that had hit its planned growth targets and now needs to stabilise", the suggestion about 3 types of CTOs and implying therefore that you effectively need 3 CTO-level managers to cover different requirements( Architecture, hiring, etc) is something that you only see at that stage. I was willing to give it a go and read through everything, but mentioning "Agile", with capital "A" as a development methodology finally convinced me that the author has no significant real-world experience in building technical startups. Hard pass.
