What we build

AI agents are making decisions and executing actions autonomously — trading, writing to memory, handing off to other agents, advising on compliance. The question is no longer whether agents can act, but whether their actions are defensible.

ThoughtProof provides verification at three levels of the agent stack:

Reasoning Verification (RV)

api.thoughtproof.ai

Adversarial multi-model verification. Independent models evaluate a claim, a dedicated red-team critic challenges the verdicts, and a synthesizer produces the final decision. For settlement conditions and high-stakes gating.

Plan-Level Verification (PLV)

verify.thoughtproof.ai

Enterprise cascade verification. Checks agent output against a plan or evidence source. Cost-efficient cascade with optional EAS on-chain attestation. For compliance, audit trails, and enterprise pilots.

Sentinel

sentinel.thoughtproof.ai

Lightweight pre-execution checkpoint. Verifies agent reasoning before irreversible actions. Four verification modes, sub-second latency, lowest cost per call. For high-frequency agentic loops.

Standards and ecosystem

We believe verification infrastructure should be interoperable. ThoughtProof participates in and builds on open standards:
