  • 343: Connection First, Culture Follows with Dr. Iain Smith
    May 7 2026

    What happens when workplace culture stops being a program and starts becoming a pattern of connection? Nikki sits down with Dr. Iain Smith, Head of Behavioral Science at Sunny, to unpack why connection is not just a nice-to-have at work, but the foundation for meaningful, sustainable performance.

    Together, they explore why culture is better understood through behavior, rhythms, and relationships than through buzzwords alone. Dr. Smith shares fresh insights on digital overload, team vibrancy, Gen Z loneliness at work, and why leaders need to stop relying on more tools and start designing better ways for people to connect, contribute, and thrive.

    From rituals and team energy to the realities of hybrid work, this conversation is a powerful reminder that when connection comes first, culture follows. If you care about people-first leadership and building workplaces that actually work for humans, this one will stay with you.
