Mishnah Oholot 1:1 · Startup voice, On-ramp

Every founder lives in the shadow of "contagion." You know the feeling: one bad hire, one toxic product manager, or one compromised decision doesn't just stay isolated. It ripples. You see it in your burn rate, your engineering velocity, and your culture. You worry that a single "dead" idea—a legacy feature that should have been sunsetted or a strategic pivot that failed—is currently leaching value out of your healthy teams.

In Mishnah Oholot 1:1, we are presented with a technical, almost clinical taxonomy of how defilement (tumah) travels from a source through people and vessels. It is a world of cascading effects. The Mishnah asks: "What is the case of two? A person who touches a corpse is defiled... and a person who touches him is defiled." It tracks the degrees of separation, quantifying how far the negative impact reaches.
