One of the greatest challenges for startup teams is scaling because usually there's not a blueprint to follow, people are learning their function as they go, and everyone is wearing multiple hats. There can be lots of trial and error, lots of missteps, and lots of valuable time and money squandered as companies scale. Matt Blumberg and his team understand the scaling challenges—they've been there, and it took them nearly 20 years to scale and achieve a successful exit.  Along the way they learned what worked and what didn’t work, and they share their lessons learned in Startup CXO. Unlike other business books, Startup CXO is designed to help each functional leader understand how their function scales, what to anticipate as they scale, and what things to avoid. Beyond providing function-specific advice, tools, and tactics, Startup CXO is a resource for each team member to learn about the other functions, understand other functional challenges, and get greater clarity on how to collaborate effectively with the other functional leads. CEOs, Board members, and investors have a book they can consult to pinpoint areas of weakness and learn how to turn those into strengths. Startup CXO has in-depth chapters covering the nine most common functions in startups: finance, people, marketing, sales, customers, business development, product, operations, and privacy. Each functional section has a "CEO to CEO Advice" summary from Blumberg on what great looks like for that CXO, signs your CXO isn't scaling, and how to engage with your CXO. Startup CXO also has a section on the future of executive work, fractional and interim roles. Written by leading practitioners in the newly emergent fractional executive world, each function is covered with useful tips on how to be a successful fractional executive as well as what to look for and how to manage fractional executives. Startup CXO is an amazing resource for CEOs but also for functional leaders and professionals at any stage of their career."—Scott Dorsey, Managing Partner, High Alpha
