Description

Jeff Byers is the co-founder and CEO of Momentous, a high-performance wellness company delivering science-backed products used by elite athletes, military operators, and high-performers worldwide. A former NFL player and two-time USC football captain, Jeff brings both personal and professional insight to optimizing performance and building values-driven companies.

What you’ll learn:

  • Why Jeff says effort and attitude are the only things you can control—and how they ground him in tough moments
  • The cultural clash behind merging two wellness companies
  • How “speed over consensus” became a core value at Momentous
  • Why returning to in-person work cost talent but aligned culture
  • How EOS helped reset their operating rhythm
  • Building high-integrity partnerships with leaders like Huberman and Starrett
  • Lessons from Pete Carroll on consistency and energy
  • Why growth-stage CEOs must “reset the scoreboard” and stay curious

Takeaways:

  • Control what you can: Effort and attitude define how you show up
  • Merge carefully: “Equals” often clash without clear direction
  • Culture lives in person: Jeff prioritized cohesion over convenience
  • Decide fast on people: Delays around misfits create drag
  • Earn trust: Authenticity attracted elite advisors
  • Balance roles: EOS clarified vision vs. execution
  • You define you: Not your title—your choices
