How do leaders stay focused during the hardest phase of scaling?

The Valley of Death, Part II: Surviving the Middle

In this episode of VHTB, hosts Brian Mejeur of AdAstra Talent Advisors, Matt Gjertsen of Better Every Day Studios, and Justus Kilian of Space Capital continue their deep-dive series on one of the hardest stretches in the life of a space startup. the middle of the Valley of Death.

After the early wins and momentum of scaling up, this phase tests a company’s culture, leadership, and clarity of mission. The team explores how founders can maintain alignment, make difficult organizational decisions, and protect morale while navigating financial constraints and operational complexity.

From lessons on leadership cadence and communication velocity to real-world examples like True Anomaly and Ursa Major, this conversation sheds light on how experienced founders survive the mid-valley turbulence, and how a clear mission and disciplined decision-making can determine whether you climb out or stall midway.
