The C-suite is the engine room of organizational success, yet most leaders struggle to build one that truly performs. It's not just about hiring talented individuals—you need the right mix of complementary skills, aligned vision, and chemistry that transforms organizations. 

In this episode of Leadership Lounge, we talk to two of our trusted advisors—Danny Ryan and Andres Gil-Casares—who share their perspectives on: 

• The biggest mistakes CEOs make when building executive teams and how to avoid them 
• Why cultural fit and behavioral alignment matter as much as technical excellence 
• How to build C-suites that can drive transformation and adapt to future challenges 
• Why leaders who admit mistakes and foster open dialogue create higher-performing teams 

"You need to find people that are interested in learning things instead of just knowing things. This means having people on your teams who are interested in asking questions, getting out of the comfort zone, and thinking outside the box."

Four things you'll learn from this episode 

1. Avoid the echo chamber—hiring executives who think like you can create dangerous groupthink; prioritize diversity of thought over comfort and familiarity. 
2. Balance technical excellence with cultural fit—the most damaging hires have strong credentials but undermine company values, causing talented people to leave. 
3. Create psychological safety for fast learning—C-suites that can admit mistakes, test quickly, and iterate outperform those focused on appearing perfect. 
4. Address performance issues quickly and compassionately—the top regret amongst new CEOs is not moving fast enough on making changes to their top team.
