Product Tracks

Two product tracks, one trust core

The randomness service is the first commercial product. AI evidence is the second growth track built on the same proof primitives.

Randomness Verification

Verifiable randomness and operational evidence for game probability items, draws, and API-based random workflows.

  • CSPRNG-based randomness API
  • Per-call usage metering
  • receipt_id and evidence export
  • AWS Marketplace and enterprise rollout path

AI Evidence Infrastructure

A product track for capturing AI requests, model calls, tool executions, responses, approvals, overrides, and external actions as audit-ready evidence packets.

  • AI workflow event ingestion
  • Tamper-evident evidence packets
  • Independent verifier and audit bundle
  • Both SaaS and procurement/package delivery

Trust Stack

Verification technology that travels across products

The core asset is not a single screen. It is an evidence format and verifier that external auditors can inspect independently.

Receipt / Proof

Bind API calls, output hashes, usage, and timestamps into one evidence unit.

Hash Chain

Preserve ordering and make after-the-fact mutation visible.

Verifier

Enable exported evidence to be checked without blindly trusting the service database.

Audit Export

Produce evidence bundles customers, auditors, and procurement reviewers can inspect.

Enterprise / Procurement

SaaS and packaged delivery on the same core

Rantropy is being shaped for both fast SaaS adoption and packaged deployments for public-sector and regulated customers. The schema and verifier stay shared while deployment and operating documents adapt to the customer environment.

  • Support for public sector, finance, healthcare, manufacturing, and critical infrastructure customers
  • Deployment paths for customer AWS accounts, private cloud, and on-prem environments
  • Offline or semi-offline verifier for closed networks and data residency constraints
  • Installation, operations, security, and audit export documentation
