Mast Origin
The control plane above your core, servicing, decisioning and bureau systems.
Mast Origin is a headless, API-first origination platform that orchestrates the full application-to-completion workflow. It sits above the specialist systems you already run, so policy, journeys, and AI agents live in Mast while execution stays in your core, servicing, and decisioning stack.
What it does.
Composable journey engine
Model applications, checks, documents, and decisions as reusable blocks. Reuse the same journey across broker, direct, branch, and API partners.
Policy-as-code
Version-controlled rules with diff, review, and rollback. Champion and challenger on live traffic before you promote a change.
Deep integrations
Connect to core banking, servicing, decisioning, bureaus, CRM, valuations, and data providers through a clean, event-driven interface.
Agent-ready surface
MCP-native, with policy guardrails and full audit trails so AI agents can operate on Mast without becoming a compliance risk.
Unified audit trail
Every input, rule, override, and agent action captured against the case. Reproducible for internal review and regulators.
Self-service configuration
Product, ops, and policy teams can change rules and criteria without an engineering release. Journeys and forms stay under engineering control so quality and compliance are protected.
