    T+334: SpaceX the Outlier, and Organization Leadership (with Matt Gjertsen)

    06/09/2026 | 43 mins.
    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.

    This episode of Main Engine Cut Off is brought to you by 32 executive producers—Steve, Ryan, Matt from Built, Russell, Joel, David, Kris, Joakim, Fred, Pat, Matt, Theo and Violet, Natasha Tsakos, Donald, Warren, Miles O’Brien, Will and Lars from Agile, Frank, Jan, Tim Dodd (the Everyday Astronaut!), Josh from Impulse, Stealth Julian, Lee, Joonas, The Astrogators at SEE, and four anonymous—and hundreds of supporters.
