What do you do when the approach that helped you break out becomes the reason your team breaks down? Early startups describe themselves like defiant, disruptive Punk Rock bands. Mature tech companies talk about coordination and precision like they’re building a Symphony orchestra. Startups in between usually sound like they’re having an identity crisis: Metrics are up, but morale is down. Hiring accelerates, but the team feels slower. There’s finally funding for big bets, but decisions feel safe. Your best people burn out while new hires struggle to fit in. Hypergrowth is exciting, until it’s exhausting. This happens because startups don’t (and shouldn’t) go directly from their Punk Rock stage to operating like a Symphony. Growing startups need a middle stage that’s more like Jazz: There’s still room to improvise, but the team has to stay in rhythm. Each stage requires different people, processes, and priorities. Applying Symphony solutions to Punk Rock problems is a recipe for disaster. Teams must learn to embrace their current stage while preparing for what’s next. Startup Stages offers a relatable framework and practical guidance for navigating these transitions. You’ll learn how to hire the right people at the right time, add process without slowing progress, and maintain your spark of innovation without burning down the house. Drawing from nearly two decades inside hypergrowth startups like Jawbone, Dropbox, Zoox, and Zipline, author Donovan Bass shows you don't have to choose between moving fast and building something that lasts. Whether you’re scaling up or feeling stuck, this book will help you reach your next stage.
