How do founders create productive conflict on their teams?

What happens when your team stops telling you what you need to hear?

Building a hard tech company takes conviction, but that same conviction can make it difficult for founders to hear opposing perspectives. When people hesitate to challenge decisions, important problems go unaddressed, and leaders risk losing access to the information they need most.

In this episode of VHTB, Justus Kilian of Space Capital, Brian Mejeur of AdAstra, and Matt Gjertsen of BUILT discuss how to create a culture where disagreement is productive, feedback is welcomed, and teams feel comfortable challenging ideas without making conflict personal.

We talk about why truth-seeking matters in leadership, how communication styles can unintentionally discourage people from speaking up, and why both founders and executive teams share responsibility for healthy disagreement. We also cover practical ways to build this skill, from understanding how colleagues prefer to communicate to using pre-mortems that help teams confront difficult questions before problems escalate.

Because productive conflict isn't about winning arguments. It's about creating an environment where different perspectives help everyone make better decisions.

Key Takeaways

  • Conviction shouldn't come at the expense of truth. Founders need people who can challenge assumptions and bring difficult information forward, even when it contradicts their thinking.
  • Productive conflict is a shared responsibility. Leaders need to consider how their communication affects others, while executive teams must also be willing to push back.
  • Curiosity makes disagreement more useful. Truth isn't always obvious, and approaching different perspectives with curiosity can uncover information that might otherwise be missed.
  • Hierarchy changes how teams disagree. As organizations grow, leaders need clearer ways to raise concerns, escalate issues, and challenge decisions without creating unnecessary friction.
  • Conflict is a skill that can be practiced. Low-stakes disagreements and pre-mortem exercises help teams become more comfortable giving and receiving difficult feedback.
  • Disagreement can reveal blind spots. Instead of treating conflict as a threat, teams can view it as an opportunity to identify problems and improve decisions.

How does your team handle disagreement? Are people comfortable challenging decisions and bringing difficult feedback forward?
