Verdict
Cross-model verification, with receipts
Clients never receive one model's opinion.
Cross-model verification, with receipts, applied where a wrong output is expensive.

I'm Nadav Spiegel. Verdict is my AI verification practice: AI implementation for high-risk environments, and enterprise verification of AI outputs at volume.
AI implementation for high-risk environments
You receive a deployment a risk function can sign: what the system may do alone, what is checked before it acts, what stays human, all in writing. I design the controls, run them in with your team, and stay until they hold. For the quarter where the pilot already works, the mandate says ship it, and every sign-off meeting ends in another meeting.his section

Enterprise verification at volume
You receive receipts, per output: the answer that survived, a confidence score, and a disagreement map. I verify AI outputs in bulk before they reach decisions, so people act on what was checked, not on what was fluent. For the moment someone asks who checked this, and the honest answer is a sampling rate.

Governed memory for your AI stack
Every assistant your organization runs is quietly accumulating memory — and almost nobody governs what gets in. Memory poisoning is now ranked the #1 threat to agentic AI systems: one planted "fact" and every downstream decision inherits it. Retrieval is not the hard problem. Custody is. Verdict Memory is a custody system for machine memory — one isolated instance per organization, run like a court, not a cache.

1 · Attributed writes — every memory carries the exact assistant, credential, and session that wrote it. Server-stamped, never self-declared.
2 · Quarantine by default — an untrusted writer's memories are held invisible to every other assistant until someone with authority rules on them.

3 · Adjudication with reasons — one designated judge per instance accepts, rejects, or salvages, and the reason is recorded. Capability is not authority.
4 · Supersede, never overwrite — when facts change, the old fact stays linked to what replaced it and why. Your audit trail reads like a ledger, because it is one.

Every mutation is logged and session-attributed — the kind of activity record your compliance and security teams are already being asked to produce for AI systems. One instance per client. No shared tables. No silent overwrites. And your assistants connect in minutes with a URL, not an integration project.

If you need AI adoption to look safe rather than be safe, I am the wrong call.
The Method
The headline is the method, and it applies to me too: nothing I hand a client rests on one model's opinion. Every claim is challenged by a rival frontier model in an adversarial debate: models from Anthropic and OpenAI on opposite sides, with a judge weighing the exchange. What survives ships with its confidence score and its disagreement map. What does not survive is said out loud.

The same discipline extends to memory: in Verdict-governed deployments, Verdict acts as the adjudicator of record for what enters long-term memory — capability is not authority.

This is not a deck. The method runs in public; test it on your own hard questions.
If your AI outputs feed decisions that are expensive to get wrong, tell me what they feed and what a wrong one costs. You'll get a reply from the person who does the work.
