It covers the soft skills necessary to execute on a high-functioning team, as well as coding skills necessary to ship well-designed features. I can’t recommend it strongly enough.'Adam RackisSoftware Engineer & Author'Congrats on PMF. Now don’t blow it. Swizec is a grizzled veteran of the surreal PMF terrain where opportunity and danger lurk. He’s created the field guide that shows you how to keep your head, keep your customers, and turn traction into lasting strength.'Kyle MathewsFounder of Gatsby and ElectricSQL'The year is 2025, and somehow Swizec Teller wrote a tech book without a single YAML deployment snippet or AI hype cycle diagram. Instead, Scaling Fast brings us something far more valuable: a practical, honest, and often funny guide to what actually makes fast-growing software companies succeed - people, teams, and a bit of architectural sanity.'Bas SteinsEngineering Leader
