Founders live in the friction between what is "legally" separate and what is "operationally" connected. You are constantly building systems—teams, product modules, or legal entities—that are distinct on a cap table but inseparable in execution. The dilemma is this: when a crisis or a contamination hits one part of your business, where does the "impurity" stop? Does your core product hold the weight of its peripheral features, or do they break off, leaving your core exposed?

In Chullin 128, the Talmud grapples with the concept of a "handle" (yad). If a partially severed limb remains attached to an animal, is it "part of the body" or a distinct entity? The rabbis argue over whether the "small" piece pulls the "large" one along with it. As a founder, you face this every time a sub-department fails. If your "handle"—your secondary service or experimental feature—is touched by a market failure or a reputational "impurity," does it drag the entire company into the mud? Or, conversely, does your core business protect the peripherals? Rabbi Meir argues that if the two are connected by function, they are one and the same. In business, you cannot claim your core is clean while your "handle" is toxic. If the handle fails, the body is compromised.
