My co-founder and I have been building our company together for several years. Not long ago, I learned that one of our investors had started to worry about our co-founder relationship. The reason was a group chat in which the two of us had gone quiet.

The worry was understandable, but it was wrong. We had not stopped talking. The conversations that matter had moved to two places nobody else could see: a weekly meeting and a weekly lunch.

Where Our Informal Time Used to Come From

For a long time, most of our informal conversations happened when we travelled. On the way to a conference and at dinner in the evening, there was time to think out loud about things that were not urgent yet.

In the office, that time hardly existed. Each of us runs a different part of the company, and our days fill up with the topics of our own teams. In weeks without a trip, the informal part of our partnership simply did not happen.

None of this was a decision. Those conversations were a by-product of travelling together, and a by-product can disappear without anyone noticing. Looking back, we had left something important to the travel calendar.

One Meeting for Decisions, One Lunch for Ideas

So we gave both parts a fixed place. First came a weekly meeting, just the two of us. During the week, we collect topics in a shared list, and in the meeting we work through them: what needs a decision, who owns what, and where we see things differently. As with our quarterly team ratings, the list matters less than the conversation it forces.

Later, we added a weekly lunch away from the office, without an agenda. That is where half-finished ideas come up, along with observations that are not ready for a decision. Longer-term questions, like the endgame I wrote about in A Revenue Plan Is Not a Strategy, need this kind of unhurried time more than a slot in a meeting.

In effect, we took the time that conferences used to give us and put it into our week, and it has helped us a great deal. Research suggests why. A meta-analysis by de Wit, Greer and Jehn found that friction between people consistently hurts teams. Disagreement about the work does not, and it is more useful in leadership teams and when it stays separate from personal friction.

The meeting gives disagreement a place. The lunch makes it less likely to become personal. In his Y Combinator talk “How to Work Together”, Kevin Hale describes small frustrations as emotional debt that is best paid down early, before it grows. A lunch without an agenda is a good place to do that.

None of this is new advice. First Round recommends weekly co-founder 1:1s and informal time outside work about once a quarter. Jason Lemkin has described one lunch each week with his co-founder, with no agenda. For us, the informal part needed the same weekly rhythm as the formal one.

How Often Does a Co-Founder Relationship End?

Nobody counts arguments, but departures are counted. Carta’s data on venture-backed US startups with two founders shows that roughly one in four lose a founder within four years. Not every departure is the result of a conflict, but it is the most visible way a co-founder relationship can end.

Investors know these numbers, so they watch for early signs. Seen against this, our investor’s worry was reasonable. What went wrong was the signal: the one channel visible from the outside had gone quiet at exactly the time when we no longer needed it to stay aligned.

Show the Rhythm, Not the Activity

My practical takeaway is not to post more in group chats. Activity in a channel says little about whether two founders agree. A busy chat can hide a conflict as easily as a quiet one can hide a good working relationship.

What an investor can actually use is the rhythm: how often the founders sit down together, what they decide there and how they deal with disagreement. That fits into one sentence of an investor update, and it says more than any amount of chat activity.

The same is true inside the company. When alignment moves from a chat to a lunch table, the team sees less of it too. Hale suggests a decision log that records the options, who decided, when and why. Our shared list is a first step in that direction, and it is easier to show than a lunch.

I am still not sure how much of this an investor needs to see. But I would rather tell our investors how we work together than let a group chat tell them for us.

The channel outsiders can see is rarely the place where co-founders actually agree.
