Hook

You’re scaling, you’re hiring, and you’re pivoting. Every founder knows the "co-founder drift" dilemma: You and your partner are holding the same knife, making a high-stakes decision for the company, but your underlying motivations are fundamentally misaligned. You’re building for a sustainable, "legitimate" product exit, while they are quietly building for a personal vanity metric, a specific investor’s ego, or a side-hustle pivot that doesn’t serve the cap table.

The Talmud in Chullin 40 presents a visceral image: "If there were two people grasping a knife together and slaughtering an animal, one slaughtering for the sake of one of all those [idolatrous/illegitimate] things and one slaughtering for the sake of a legitimate matter, their slaughter is not valid."
