What this episode covers
Gillian Muessig has spent 26 years watching founders and leaders navigate pressure across 50 countries. As Managing Director of Mastersfund™, she has sat across the table from CEOs at their highest and lowest points, studying what calm authority actually looks like in high stakes decision making. But this episode is not only about what she has observed. It is about what she lived. When her husband died, Gillian kept showing up, kept leading, and had no idea she was being carried. Her business partner, Anne Kennedy, quietly took over seven-eighths of the load without ever naming what she was doing. Claire and Gillian unpack what that kind of co-regulation looks like through the lens of neuroscience leadership, why stress resilience separates the leaders who survive their hardest year from the ones who do not, why founder mental health deserves the same rigor as any other business metric, and why the ability to step back and see the whole chessboard is a trainable capacity for senior leader development, not a personality trait.
