Burn Rate by Andy Dunn, published in 2022, is a memoir about building a startup while living with bipolar disorder. Dunn co-founded Bonobos, the online menswear brand, in 2007 and led it until Walmart bought the company in 2017. In this book he tells the story behind that success: years of hiding his diagnosis, a dangerous manic episode and the slow road to treatment and recovery.
What is Burn Rate about?
The book follows two tracks at once. One is the business story: a business school student who wants to sell better-fitting trousers online, a co-founder with the product idea, early fundraising, rapid growth, expansion into physical stores and the sale. The other is the story of Dunn’s mind. He describes periods of soaring energy and grand plans, followed by deep lows, and how both shaped his decisions as a CEO.
Dunn writes openly about the stigma that kept him silent. He feared that investors, staff and partners would lose faith if they knew. That silence kept him away from consistent treatment until a severe manic episode forced the issue. The book describes the crisis, the help that followed from family and doctors, and what it took to rebuild his life and career.
What sets the book apart from most founder memoirs is its focus. The business lessons are present, yet the main subject is the hidden toll that startup culture takes on mental health. Dunn uses his own case to argue that founders should talk about these conditions openly, and that the startup world should stop treating extreme intensity as a virtue.
What are the main lessons for founders?
- Know your own warning signs. Sleepless nights, racing plans and sudden crashes can feel like founder energy. Learn your patterns and share them with someone you trust.
- Get treatment before a crisis. Dunn’s story shows the cost of delay. Regular care from a professional protects your health and your company.
- Tell your co-founder. A co-founder who knows your situation can step in during a hard period instead of being caught off guard.
- Build a support system outside work. Family, friends and peers outside the company give perspective that investors and staff cannot.
- Lead by being open. When a founder talks honestly about mental health, employees feel safer asking for help themselves.
Who should read Burn Rate?
Founders and early employees who feel the pressure of startup life on their mental health, and anyone living with a mood disorder who works in a high-stakes job. Investors and board members also gain a lot, since the book shows how founder health affects a company. It helps at every stage, from pre-launch to exit.
Readers looking for tactical advice on building a consumer brand will find only part of what they want. The business details serve the personal story, not the other way round.
How do you put Burn Rate to work this week?

Where does Burn Rate fall short?
Dunn writes from a position of privilege: elite business schools, strong networks and enough money to get good care. Founders without those resources will face harder obstacles than the book describes. The story is specific to bipolar disorder and offers less for people dealing with anxiety, burnout or depression alone. The business sections are thin for readers who want to learn how Bonobos grew.
