Zero to One: Notes on Startups, or How to Build the Future

Thiel's argument is simple and polarising: genuinely new companies create monopolies by doing something no one else is doing, and "competition" in the conventional sense is a sign that everyone is copying each other. The book compresses a Stanford course into short, aphoristic chapters; Thiel's style is contrarian in a calculated way and some of the positions have aged better than others. For product direction the most portable idea is the distinction between horizontal progress (copying what works) and vertical progress (doing something genuinely new), and the argument that most corporate innovation spends its energy on the former while claiming the latter. Read critically; worth reading.
