Brass Check is a marketing and PR agency founded in 2014 by 📝Ryan Holiday, specializing in book launches, longform-content campaigns, and reputation work for authors, executives, and creator brands.
The agency emerged from Holiday's own background as marketing director at American Apparel and his subsequent track record as the bestselling author of Trust Me, I'm Lying, The Obstacle Is the Way, Ego Is the Enemy, and the Stillness Is the Key trilogy. Brass Check's roster has historically included authors such as Tim Ferriss, Tony Robbins, Robert Greene, and James Altucher, alongside individual founders and venture-backed companies looking for narrative work that sits between traditional book marketing and modern content distribution. The firm operates from Holiday's Bastrop, Texas base and tends to take on a small, hand-picked roster rather than a large agency book of business.
