A new approach to collaboration, productivity, and growth from Sid Sijbrandij, the cofounder and executive chair of GitLab.

If you want to go fast, go alone. But if you want to go far, go together.

This familiar saying has inspired leaders for years. But what if it’s wrong? What if achieving extraordinary results didn’t mean choosing between speed and teamwork?

In Extreme Collaboration, entrepreneur and thought leader Sid Sijbrandij shares the secret to quickly and efficiently achieving impactful outcomes: an open mindset. Drawing from his extensive experience building companies, Sijbrandij reveals how the same principles that drive open-source projects—collaboration, iteration, intentional transparency, efficiency, and a focus on results—can be applied to any organization or initiative. These same tactics have built GitLab into one of the world’s largest all-remote companies, started new ventures, scaled nonprofits, and have even shaped his own personal cancer treatments.

Through actionable strategies and compelling stories, leaders at all levels will learn how to build upon the best ideas, refine them with agility, and foster a culture of openness and trust. Challenging the belief that leaders must prioritize either synergy or speed, Extreme Collaboration empowers you to unleash the potential of your team and organization to achieve more than you thought possible.

Whether you’re a leader at a startup, nonprofit, or global corporation, Extreme Collaboration is the ultimate guide to driving bold results faster—together.
