Hook

You’re staring at a product defect. A customer finds a "needle in the haystack"—a subtle, latent issue in your code or hardware that wasn’t there when it shipped, but surfaced later. The customer wants a refund, citing "latent defect." Your engineers argue it couldn't have happened on their watch. Your legal counsel says, "Show me the proof it happened before delivery."

It’s the classic founder’s dilemma: Where does the burden of evidence lie when the timeline of a failure is opaque? You want to be a Mensch, but you’re running a business, not a charity. If you accept every claim of a "pre-existing condition," you bleed margin. If you reject them all, you destroy your reputation and lose the trust that fuels your LTV.
