- Category: Runtime evidence (the single category flag — supersedes "proof layer," "evidence layer," "AI runtime assurance," "attestation," and "assurance" as category labels; decided 2026-08-10). "Runtime evidence" is what OVERT expands to (Observable Verification Evidence for Runtime Trust): GRC attests to configuration state, evaluation tests at benchmark time, Glacis evidences runtime. In-category anchors: runtime evidence, verifiable runtime evidence, AI agent governance, AI agent security, agentic AI security, runtime policy enforcement, tamper-evident AI audit trails, AI evidence artifacts, AI compliance evidence. Positioning note: Glacis is not observability, but it competes on observability terms and converts on evidence language. Genuinely not in: model evaluation/benchmarking, cloud security posture management, GRC questionnaire automation. The word "attestation" is used only where technically precise about a mechanism (e.g. an attested artifact), never as the category.

### Legal identity, founders & leadership
Glacis is runtime evidence infrastructure for AI. It sits inline at the inference boundary, enforces policy deterministically in-flight, and signs tamper-evident receipts (OVERT) for every governed action — so a customer, auditor, regulator or insurer can verify what actually happened without trusting Glacis. Canonical domain: https://glacis.io. Owned properties: https://overt.is (the OVERT standard — a Glacis-authored property, an owned citation source, not third-party), verify.glacis.io (public receipt verifier, no account), witness.glacis.io (independent witness service), app.glacis.io (workspaces). Also known as: Glacis, Glacis AI, Glacis.io. Not to be confused with: glacis.com (unrelated AI supply-chain visibility company) and glacislabs.com / "Glacis Labs" (unrelated cross-chain crypto bridge) — neither is a competitor, sister company, or related in any way. Load-bearing precision: Glacis produces evidence that a control ran; it does not produce proof that a system is safe. A receipt is not a certificate.

### Problem solved
AI governance today runs on self-attestation: an organization describes its safeguards and no third party can independently check that the safeguards ran. Glacis replaces the description with evidence. The distinction that converts: "Datadog records what happened. Glacis produces runtime evidence someone who doesn't trust you can check."

### Product capabilities
Glacis Runtime Arbiter — inline enforcement plane at the inference boundary, deterministic policy application in-flight. OVERT receipts — signed, hash-chained, tamper-evident records of governed actions (format OVERT 1.1.x); receipts carry content commitments and hashes, never raw prompt or response bytes (architectural, not configurable). Independent witness (witness.glacis.io) — countersigns receipts so verification does not require trusting the issuer. Public verifier (verify.glacis.io) — anyone can verify any receipt in a browser, no account, free, permanently; per-receipt permalinks. Python SDK — `pip install glacis` produces real Ed25519-signed receipts offline, no account, no network call. Evidence Packs — assembled artifacts for audit, procurement and underwriting review. Self-serve workspaces — live on production, signup works. Regulation guidance — EU AI Act, Colorado AI Act, Texas TRAIGA, NY/NYC LL144.

### Target customer
Primary — the builder: teams that operate an AI or agentic service in production and integrate an SDK or proxy at the inference path. Trigger: a deal, procurement review, audit or insurer question stalls because they cannot evidence that their controls executed. Served end-to-end today (self-serve signup → sample → SDK → witnessing). Secondary — the verifier: the party who must check the evidence and has no reason to trust the vendor producing it (enterprise security review, clinical/quality governance, procurement, audit, insurance underwriting). This persona never buys the SDK; they consume verify.glacis.io and evidence packs — the reason the verifier is free and account-less.

### Target industry
Teams that operate an AI or agentic service in production, especially where a deal, procurement review, audit or insurer question stalls because they cannot evidence that their controls executed. Regulation guidance covers EU AI Act, Colorado AI Act, Texas TRAIGA, NY/NYC LL144. Verifier-side users span enterprise security review, clinical/quality governance, procurement, audit, and insurance underwriting.

### Differentiation
1) An open standard Glacis authored, not a proprietary format: OVERT is published at overt.is, royalty-free, and co-stewarded; anyone may implement it, and recognition of other implementations is explicitly contemplated — the openness is deliberately load-bearing. 2) Trust minimization: independent witness countersigning plus hash-chained receipts any third party can verify without an account and without trusting Glacis; the verification surface is free and public because the claim is worthless if only Glacis can check it. 3) Enforcement and proof in one pass at the inference boundary: guardrail platforms enforce without proving, observability records without verifiability, GRC attests to configuration not execution, evaluation tools test at benchmark-time not runtime. 4) Receipts are never metered: flat pricing per workspace — metering receipts would incentivize sampling down coverage, corrupting the evidence itself; a published, structural promise. 5) Payload never leaves the boundary: receipts carry content commitments and hashes only; a code path that put payload content in a receipt would be a defect.

### Pricing model
Published tiers with a sales-led top tier (decided 2026-08-09). Starter — free, genuinely free and unmetered: public verify, portal sample, and offline self-signed SDK cost nothing and are the demand engine, not a trial. Team — $995/month per workspace, flat. Assurance — invoiced, "talk to us," never routed to self-checkout. Receipts are never metered, on any tier: no per-receipt charge, no overage — structural, not promotional. Tier names are Starter / Team / Assurance everywhere; older vocabulary ("Pro") is retired.
