The Hidden Cost

Single-perspective AI inherits a single perspective’s blind spots.

Even sophisticated professionals can’t detect flaws they aren’t shown. When a single AI delivers a conclusion, you inherit its training data bias, its failure modes, and its tendency to express confidence in places it shouldn’t.

Your reputation depends on analysis that survived rigorous challenge — not analysis that just sounded convincing.

Why Multi-Model Matters

Competing intelligences. Competing conclusions. One defensible record.

In M&A, investment committee prep, and litigation strategy, the answer that wins is the one that survived pushback. Delibera runs the pushback internally — before the associate, the MD, the IC partner, or opposing counsel has a chance.

Three independent models. Three analytical mandates. Mandatory dissent. A synthesis that earns the conclusion instead of defaulting to it.

Benchmark Deep Dive

Tested against frontier models. The data.

Phare Hallucination Benchmark (n=350 subset of 791 adversarial misinformation samples) and proprietary adversarial suite (1,141+ total samples) across frontier models. Delibera is the only system tested that expresses uncertainty — 26% of challenging cases.

What the numbers mean for your next deal

A 41% reduction in hallucination rate isn’t abstract. At typical EBITDA multiples of 4–8x, catching a single $50,000 quality-of-earnings error that would otherwise propagate through the valuation saves $200,000–$400,000 in deal mispricing. For a mid-market PE firm doing 5–10 deals annually, the ROI case for Delibera is one caught error.

Case Law · What Happens Without This

A full ledger of documented AI-hallucination sanctions.

Every one of these started the same way: a professional trusted a single-model AI output without independent verification. The pattern is consistent — and it’s accelerating.
