Enterprise

Three plans,
chosen by need.

Each plan configured to your requirements via Discovery.

Public · Civic services

Lemma Civic

For organizations serving citizens

Best for For municipalities, utilities, and B2B2G operators that need verifiable attribute checks for citizen-facing services.
  • Civic-eligibility checks that confirm the fact without revealing the data (zero-knowledge proof)
  • Multi-site tiering — scales with the number of operating sites
  • Tamper-evident provenance records for audit and public accountability
  • Standard schema library for civic infrastructure
Tier 1 1–3 sites
Tier 2 4–10 sites
Tier 3 11+ custom

Positioned for small municipalities. Annual contract, configured per site count, verification volume, and custom schema registration via Discovery. As sites or volume grow, it moves up a tier. Option Packs not applicable.

  • SLA-backed uptime · on-premises deployment option
  • Tiering by facility count and integration scope

Option Packs

Choose by the goal —
three extensions.

Goal-driven extensions. Available from Tier 2 on Critical or Compliance.

Pack A

Incident Response

From incident,
to recovery and proof.

An operational pack for root-cause analysis, recovery, and regulatory reporting from a tamper-evident provenance trail at incident time. Slots into the CISO / internal-audit response process.

Available on Critical Tier 2+
Entry PoC-A / PoC-B
Pack B

Regulatory

Compliance,
recorded as a proof trail.

Supports conformity to EU AI Act, the Active Cyber Defense Act, and domestic critical-infrastructure rules on both the technical and documentation sides — including NCO-format submissions and conformity evidence.

Available on Critical T3 / Compliance T2+
Scope NCO format · EU AI Act
Pack C

Agent Governance

AI agents,
ready for enterprise governance.

An operational pack for organizations where AI agents handle delegation and automated transactions. With Trust402, an independent verification layer for agent authority slots into enterprise governance — for expense approval, procurement, and customer-facing automation.

Available on Compliance T2+ / Trust402 integration
Entry PoC-C

Scope: Option Packs add on from Tier 2 on Critical or Compliance. Civic is out of scope (public-utility pricing preserved); Tier 1 is out of scope on every plan (lightweight tier). Pack combinations get designed against business requirements in the Discovery session.

FAQ

Pricing —
common questions.

Why are prices not published?

Enterprise pricing depends on tier, site count, SLA requirements, and ZK circuit complexity. Numbers without context mislead, so we price against your actual use case.

Which plan fits my organization?

Citizen-facing services and utilities → Civic. AI embedded in operational systems with business-continuity demands → Critical. Attribute verification, audit trails, regulated workflows → Compliance. Building on x402 / MCP → Trust402. We map you to the right plan during Discovery.

How is pricing set?

Enterprise plans are annual contracts: monthly base + verification volume + optional custom-schema registration, plus Option Packs when relevant. Discovery returns a Tier + Pack proposal from Lemma.

How do Option Packs get selected?

Option Packs aren't sold standalone — they gate to Critical / Compliance Tier 2 and above. Discovery intakes the business requirement; Lemma proposes a Tier + Pack configuration. Civic and Tier 1 on every plan are out of scope.

Is there a free trial?

Trust402 includes the Explorer tier for sandbox evaluation. Enterprise evaluation runs via a scoped PoC.

When does Trust402 launch?

Detailed pricing publishes with the x402 integration demo. Join the waitlist to hear first.

Can we start at a lower tier and upgrade?

Yes. Every enterprise tier is designed to move up as the deployment grows.
