What This Means

YC S25 companies score highest on The 5-Second Verdict (61.0/100 avg) and The Logo Test, but collapse on The Status Quo Tax (35.8/100). Most teams assume their buyer already knows the problem. They don't. The Proof Stack is nearly as weak -- 54% of these companies show zero social proof. No logos, no testimonials, nothing.

The companies that win this batch aren't perfect messengers. They simply nail The Status Quo Tax: "Why should I care right now?" and "What happens if I wait?"
