Ask HN: Startup CTO required reading?

Hello HN,

Next week I join a (venture-backed) startup as CTO after spending the last 5 years as a one-man dev shop (I have experience prior to that of managing large teams of developers)

Now that I have secured this new position back in management I am suffering from a touch of impostor syndrome - could the HN community help me out by pointing me at resources that I should read up on, to have the most up to date background on startup CTO level tech management?
