Lean Out examines why attempts to close the gender gap have fallen short and argues that rewiring the business world’s idea of a “successful leader” will unlock real diversity and healthier workplaces for everyone. Part manifesto, part practical guide, this book by Marissa Orr—a veteran of Facebook and Google—speaks to professionals, managers, and women navigating the modern corporate landscape. With a candid, witty, and evidence-based tone, Lean Out invites readers who want meaningful change without sacrificing well-being.

Structured as a series of accessible arguments and revealing personal stories, Lean Out blends research, firsthand experience from Orr’s fifteen years in tech, and concrete takeaways. She shows how current diversity trainings can miss the mark and how defining success on your own terms can empower women and men to perform at their best. The book is engaging, often humorous, and practical, offering a pathway for individuals to reclaim well-being while encouraging companies to rethink leadership norms. Readers will discover key concepts about leadership paradigms, workplace culture, and strategies to foster inclusion that benefits all employees.
