Can you be fully committed to a startup on a 9-to-5 schedule?

For years, startup culture has pushed the idea that if you're not working around the clock, you're not really committed. But is that actually true?

Can you be fully committed to a startup while still making time for your family? Where's the line between being mission-driven and burning people out? And how should founders think about commitment as their companies grow?

In this episode of VHTB, Matt Gjertsen is joined by Justus Kilian of Space Capital and Brian Mejeur of AdAstra Talent Advisors to unpack why commitment isn't as binary as people often make it out to be. We explore what founders should expect from themselves versus their teams, why trust and autonomy matter more than hours in the office, and how great leaders create clarity around expectations instead of relying on optics.

From the intensity of the earliest startup days to building organizations that can support different life stages, we discuss what sustainable, high-performing cultures actually look like, why clearly defining roles matters, and how leaders can create environments where ambitious work and life outside the office don't have to be at odds.

Episode Takeaways

  • Commitment exists on a spectrum, not as an all-or-nothing mindset.
  • High-performing teams are built around trust, autonomy, and outcomes rather than time spent in the office.
  • Founders and employees have different incentives, and healthy cultures acknowledge those differences.
  • Early-stage startups may require intense commitment, but mature organizations should evolve beyond that model.
  • Leaders shape culture by modeling the behaviors they want their teams to feel comfortable embracing.
  • Clearly defining roles helps employees understand expectations without relying on unspoken assumptions.
  • Companies that support different life stages are better positioned to attract and retain great talent.
  • Management responsibilities should be intentional, not simply added on top of individual contributor work.
  • Proactive communication prevents many of the commitment issues managers often attribute to motivation.
  • Sustainable hard tech companies are built by creating environments where ambitious work and personal life can coexist.
