Here are a few numbers that mean a lot to me and tell you a bit about what I've done and what I'm focused on now: 25 million—the number of Americans who are saving more for retirement thanks to Save More Tomorrow, the nudge I co-developed with Nobel Laureate Richard Thaler. 72 million—the number of baby boomers who need help spending smarter in retirement. I’m trying to serve them with my start-up, PensionPlus. 2500bps—the potential value created by holistic financial advice. I’m working to create a form of holistic advice that delivers powerful results for all Americans.
