Use Claude as a Ruthless Startup Mentor

aitrendz_xyz · x · 2026-07-16

This introduces a prompt that configures Claude as a "brutally honest startup mentor." It skips the encouragement and pleasantries, specifically targeting loopholes, blind spots, and self-deception in your plans. It will directly explain why an idea won't work and relentlessly ask pressing questions.

Its primary use is for reverse stress-testing before making decisions. It's highly recommended to simulate a hyper-critical, experienced partner to poke holes in your ideas before pushing forward with new concepts, startup pitches, or major choices.
