    Founder and CEO of Auriga Space, Winnie Lai, joins me to talk about their electromagnetic launch infrastructure and the path she sees for Auriga across space and defense markets.

  • T+334: SpaceX the Outlier, and Organization Leadership (with Matt Gjertsen)
    2026/06/09

    I often talk about SpaceX being an extreme outlier in the industry and how many organizations have tried to replicate their approach, but very few (if any) have been successful. Matt Gjertsen of Built joins me to share a take on what exactly it is internally that drives their results, how to apply it in other organizations, and to share some perspective on his time at SpaceX leading Training and Development, and from elsewhere in the industry.
