Preuve AI is the closest competitor in spirit — its real strength is verifiable rigor, deliberately built to counter "everyone gets a green light" validators, at exceptional credibility-per-dollar. Crucible’s seam is the depth and adversarial frame above a fast report: a 14-stage tech tree (JTBD, unit economics, regulatory, IP, deal terms), a measured readiness assessment, and an investor memo with explicit kill-paths — answering "would this survive an IC," where Preuve answers "is the evidence real, fast."
