The world’s fastest-growing B2B companies are borrowing and adapting pages from the BC2 growth playbook and using new technologies and tools to build powerful engines of sustainable breakout growth. This drove Sean Ellis' & Ethan Garr's interest in studying some of the fastest-growing B2B companies on the planet. If they could better understand how and why proven B2C growth approaches were driving breakout growth, where companies were struggling and succeeding in implementing these ideas, and understand what was proving challenging for these entities, they felt like they could help others on the cusp and in the midst of breakout growth to reach their full potential. These studies each started with growth leader interviews on The Breakout Growth Podcast. From conversations with CEOs, heads of growth, marketing and product leads, and others they learned how a broad range of highly successful B2B companies are building the teams, processes, and mindsets to build and sustain rapid growth.
