What if the biggest thing slowing your team down isn't a lack of talent, but a culture where no one feels safe enough to tell you the truth?

Most leaders learn to project certainty, control, and composure at all costs. But that emotional armor comes at a hidden price: silence, filtered information, and teams that quietly protect themselves instead of solving problems. In Leadership by Design, former COO and consultant Brennan Renvik shows that the strongest leaders aren't the ones who never show uncertainty—they're the ones who build enough trust that others can speak openly.

Grounded in research from Google's Project Aristotle, Amy Edmondson, Brené Brown, and behavioral science, this book reframes leadership as a daily engineering task. Through real case studies—from Satya Nadella and Alan Mulally to Jacinda Ardern—Renvik reveals how courage under pressure creates the psychological safety that lets teams become honest, resilient, and self-sustaining.



Inside, you'll discover:



- Why armored leadership quietly erodes trust and how to drop it without losing authority

- How to name emotions before they run the room and turn tension into honest conversation

- A practical method for having the difficult conversations you'd rather avoid—the "rumble"

- How to deliver feedback that lands without wounding and build trust as a daily practice

- Ways to work with failure instead of hiding it, so problems surface early

- A 30-day field guide to turn these ideas into repeatable leadership habits

Stop managing around your team's silence—and start building one that runs itself.



Brennan Renvik is an American consultant and former operations executive specializing in operational efficiency, leadership, and the personal productivity of technology-company leaders. He earned an engineering degree from a leading American university and an MBA from one of the top U.S. business schools. Over twelve years in the SaaS and fintech industries, he rose from head of operations to COO, leading one B2B SaaS company from $7M to $90M in ARR and an exit to a strategic acquirer, and later serving as COO of a fintech unicorn with a team of fifteen hundred people across ten time zones. That experience became the source of his "Single Action Method," the principle that every project, meeting, or decision must end with a single next step, a specific owner, and a specific date. Today he runs his own consulting practice for the CEOs and COOs of scale-up companies, leads closed cohort programs for operations directors, and coaches senior executives on leadership and personal effectiveness. In his books, he explores operational discipline in the era of distributed work, leadership as a daily engineering task, and the personal productivity of the leader.
