Not specific to just tech teams, but I loved The Outsiders: Eight Unconventional CEOs and Their Radically Rational Blueprint for Success by William Thorndike. So many great notes about leadership and successfully running a business in general.

There's an excellent book (you're probably aware of) called The Outsiders. It compares the results of operations focused CEO's like Welch to capital allocators like Buffett, Singleton, and Malone. The thesis is that overtime, the good cap allocators just blow everyone else out of the water.

“An outstanding book about CEOs who excelled at capital allocation.” — Warren Buffett
