ZenTreasury is the financial contract accounting subledger for lease and treasury, built for the Office of the CFO. Your ERP posts the entry. It doesn't know the contract behind it. ZenTreasury does. Add a lease once and get the full schedule: right of use asset, liability, and period by period amortization generated automatically. Index-linked remeasurement is handled automatically. Every modification recalculates the schedule and keeps the per-field audit trail intact. On the treasury side, manage FX positions, loans, guarantees, and group wide cash flow forecasting in the same platform, multi entity and multi currency by design. One product, accounting included, priced to the scope you run. Every customer gets a dedicated, isolated database. Lease calculations are independently reviewed by an international audit firm. Connect your own AI, Claude, ChatGPT, or any MCP client, directly to your contract data.

Okyline is an Executable Data Design (EDD) platform for declarative data validation contracts and measurable operational data quality. Instead of maintaining disconnected specifications, validators, tests, and quality dashboards, Okyline uses a single executable contract as the operational source of truth for validation and flow quality monitoring. The same readable contract drives multi-format validation, deterministic execution, quality measurement, data quality gate, and historical quality analytics across APIs, events, files, LLM structured outputs, and enterprise data flows. Community Edition provides the open specification, a free Java validation runtime, a public Claude AI assistant for contract generation, and a free online studio for executable JSON validation contracts and JSON Schema transpilation. Enterprise Edition supports direct validation of JSONL, XML, CSV, FIXED, and EDI flows, data quality gate, and operational quality dashboards, all without databases
