Platform / Architecture

How Mast fits into your stack.

Mast is a headless, API-first origination platform. Channels, origination, parties, and analytics are all part of Mast. The decisioning and data services it orchestrates sit alongside it, and core banking and servicing systems sit below as systems of record. You keep your specialist systems; Mast gives you the control plane on top.

Three ways to deploy

Sit next to, replace, or hybrid.

Sit next to

Keep your core, servicing and bureau providers. Mast replaces the origination layer only. Fastest route to a modern application-to-completion journey.

Replace

Retire the legacy origination platform end to end. Mast becomes the single system of engagement across brokers, customers and underwriters.

Hybrid

Run Mast for new lines like Later Life Lending or Specialist, while your legacy platform runs the back book. Migrate journeys one at a time.

Where Mast sits

The origination layer, above the systems of record.

Mast owns the channels that feed cases in, the origination engine that processes them, the parties and users that touch a case, and the analytics and warehouse layer that makes it auditable. The decisioning and data services it orchestrates sit alongside it, and core banking and servicing systems sit below as systems of record. Everything outside the Mast-owned layers stays yours.

Orchestration

No fixed sequence. One audit trail.

Mast does not impose a linear pipeline. You decide which capabilities run, when they run, and how often, per journey, product, or channel. Steps can run in parallel, repeat, loop back, or be skipped entirely, and everything Mast touches lands in the same audit trail.

Intake, any channel

Broker portal, customer portal, intermediary API, or your own UI on the Headless SDK.

Data and checks, on demand

Identity, credit, affordability, and property data called at whatever point your policy needs them, and re-called when the case changes.

Policy and product evaluation

Policy Engine and Product Engine can run continuously as the case evolves, not once at a gate.

Case Copilot

Summaries, exception flags, and drafted notes available at any stage, not just before underwriting.

Human judgement, where you want it

Automate, review, or refer by product, channel, or risk band, and move that line whenever you choose.

Downstream events

Booked loans, decisions, and documents pushed to core, servicing, and your warehouse as events, in your order.

Principles

Built for the next decade of lending.

Headless and API-first

Every capability is exposed as an API. Drive Mast from your own broker portal, customer app or internal tools using the Headless SDK.

Agent-ready case surfaces

Mast exposes case surfaces and policy APIs that agents can read and act on inside your rules, with full audit.

Policy as code

Your lending policy is a golden source in Mast. No more Excel and Word documents drifting apart from what production actually does.

Composable connectors

Swap bureaus, valuers, identity providers per journey. No lock-in, no rip and replace.

Secure by default

ISO 27001, Cyber Essentials Plus, IP whitelisting, and granular role-based access. SSO on the roadmap.

Deploy where you need to

Cloud native. Dedicated tenancy and regional deployment available for banks with sovereignty requirements.
