The $100M Push, Broad Book Press, March 2026
Marni Seneker wasn’t just the book coach for Lead Like The Boss. She was something much more important: a true believer. From the first moment of working with her, she believed in me and believed in the project—and it showed. She helped me make the book a reality and helped at every turn. As a certain singer-songwriter would say, she believes in The Promised Land. And I believe in her.

Marni’s proactive approach, attention to detail, and genuine interest in my work made her feedback incredibly relevant and valuable. She’s an exceptional brainstorming partner, and I feel very fortunate to have collaborated with her during this pivotal stage in my author journey.”​

Marni provided perspective, confidence, and clarity during our co-authoring process. She helped us get clearer and more concrete, she saved us time in certain places, and she helped us get to a stronger product.

Extraordinary Learning For All, Jossey-Bass, November 2024
[Marni was] the most professional, together, organized, and deeply competent of everyone we interviewed. I wanted someone who was going to be clear, tough, and honest and she was that. Having her as a trustworthy, efficacious, no-nonsense collaborator and member of the team was the most valuable factor. The way that she leaned in felt incredibly team-centered and deepend trust.

Extraordinary Learning For All, Jossey-Bass, November 2024
Without [Marni's] support, her encouragement, her motivation, and, more importantly, her sincere caring and her deep probing into what I was trying to say, it would have never been. Marni has become, not surprisingly, a dear friend–I cannot thank her enough.​

Crafting the Sale, Girl Friday Books, September 2023
Marni helped me decipher my core themes and understand how to build from one point to the next. When my writing got particularly opaque, she talked me through the material with her characteristic wisdom, deep philosophical insight, and effective questions. She offered pragmatic writing tools and guidance, as well as a strong intuitive sense of what was most important about my work. She is an alchemist who helped transform my hot mess of jumbled ideas into a lucid text.

Breathe Deep, Adams Media (an imprint of Simon & Schuster), 2023
Marni exceeded my expectations. She has an intuitive sense of how a nonfiction book should be organized, and she helped me stay on track with the largest writing project I've ever undertaken."​

Kelley Holland
You Are Worthy, She Writes Press, September 2022
Marni is a master at helping to architect a story. When I brought her my original manuscript, Marni gave me two things. First, she provided me with honest feedback that I needed to hear. Second, she helped me step back and walk through the arc of the story that I wanted to communicate authentically. Marni struck this incredible balance of not only being a coach, but also one who was willing to roll up her sleeves to offer suggestions and clear, actionable edits. If you want someone who will help take your ideas and translate them into a book that engage readers, Marni is your go to person!​

Marni was able to give constructive and actionable feedback from both a big picture and detailed perspective. Her insights helped me reshape and refine the manuscript for publication.​

Colin Bryar
Working Backwards, St. Martin's Press, February 2021
Marni’s keen insights and direction on the structure and content of the chapters she reviewed for The Grit Factor was incredibly helpful! She understood how to guide me, in my own voice, to weave the powerful anecdotes of female leaders into a unified story of grit.​
