The thesis: every early-stage startup needs one person who is both responsible for the outcome and has the right to make the final call. Not consensus. Not a vote.
The group decision argument sounds reasonable — more knowledge, more guardrails. But under real pressure, self-interest dominates. And when nobody owns the outcome, nobody cleans up the mess. After my last startup wound down I spent over a year returning $1M to stakeholders as a volunteer. Everyone else had moved on. That's what ownership actually looks like.
I think of it as a trust test. One person has to be willing to hold full liability. The other has to trust that person's judgment and integrity enough to give them the final call. Not all co-founder relationships can do that — and the ones that can't eventually blow up.
Curious if others have seen this play out differently, especially in cases where consensus-based structures actually worked long-term.
