Jaust Unveils Automated Underwriting Platform For Jumbo Mortgages

JAUST, an automated underwriting system (AUS) built specifically for jumbo mortgage originations, has launched with a cloud-native platform that aims to help lenders cut underwriting costs and accelerate decision times, the company announced Tuesday.

The platform is designed for portfolio lenders and mortgage banks that manage dozens of jumbo investors and complex overlays.

“The mortgage industry has been stuck with legacy systems and manual workarounds for too long,” Michael Hurley, JAUST’s founder and product owner, said in a statement. “JAUST was built from the ground up to eliminate bottlenecks and bring intelligent automation to segments of lending that have been left behind.”

At its core, JAUST is a cloud-based underwriting engine that classifies and extracts data from more than 50 document types. It applies a lender’s full credit, eligibility and documentation guidelines in real time, according to the company. The system returns structured, auditable recommendations that are designed to reduce human error and improve pull-through rates.

JAUST is aimed at lenders that either hold jumbo loans in portfolio or sell them into multiple private-label and investor execution options. For these institutions, aligning loan decisions with fast-changing guidelines and documenting them for audits and due diligence are core operational and risk management challenges.

The platform is built as a modular system that can be deployed individually or as a fully integrated stack.

JAUST Core is the platform’s automated underwriting system. It uses data extraction, rules-based evaluation and real-time decisioning to generate underwriting recommendations.

Program Advisor functions as a program and pricing engine. It scans hundreds of investor guidelines to identify potential eligibility and execution options.

Credit Advisor is a credit decisioning tool that applies configurable credit guidelines to tri-merge credit reports and returns automated determinations to accept, review or escalate a file.

Lastly, Shield is an internal rules module that manages more than 1,000 guideline parameters across lender and investor overlays, allowing centralized policy management.

JAUST is delivered as a software-as-a-service (SaaS) platform built on Microsoft Azure. JAUST said the system supports anonymized processing and audit logging. It can connect to existing loan origination systems but does not require LOS integration to begin using the tool.

The company said most lenders can implement JAUST and go live in a matter of weeks, positioning the tool as a near-term option for originators looking to rationalize jumbo underwriting resources ahead of the next rate or credit cycle shift.

“We’re here to bring intelligence and speed to underwriting — not by replacing the underwriter, but by augmenting what they do best with tools that are smarter, faster, and built for scale,” Hurley said.
