The Chat - AI, Fear, and the 40% Rule: What Great Leaders Do Differently

“Helping people operate 10% better is one of the highest ROI things a company can do – and most ignore it.”

 – Bill Lennan

In this episode of The Chat, host Terry Wilson sits down with Bill Lennan, founder of 40% Better, to unpack how great leaders unlock extraordinary team performance. Bill shares the real story behind his “40% Rule” – the system he used to turn the worst-performing software team into the best in just six months. His message is clear: the biggest untapped ROI in any business isn’t in tech or tools – it’s in people.

From building psychological safety that sparks innovation to creating backchannel alignment between product, sales, and marketing, Bill reveals how smart leaders drive measurable results – 4X pipeline growth, faster delivery, and more loyal teams. He also takes on the hype around AI, explaining why human connection and trust still outperform any algorithm.

If you lead teams, run sales, or manage marketing in a high-pressure B2B environment, this episode will change how you think about performance, culture, and growth.

🎧 Listen now to learn why being 40% better beats trying to be perfect.
