This is only "Funny" in the sense that it's "funny" that a high-performing startup can run the entire thing on a single huge Postgres instance and that mysteriously stops working after you hit a certain level of scale. Relationship count scales quadratically as you scale headcount. A single poor relationship can sour an entire team or worse. When your team is 5 people, it's trivial for e.g. the CEO to have the state of all relationships in the company in his head. As a company grows larger it gets harder. Once you surpass Dunbar's number it's virtually impossible. The function of 1:1s is to scale this.
