THE OPERATION BEHIND THE INTERFACE
A loan application has to become something the lending team can act on: a connected deal, a complete set of documents, recorded authorization, and a signed application.
The work brings borrower intake, internal operations, and Vaster’s existing systems into a shared workflow. The details matter at every boundary—what gets updated, who can see sensitive information, where a document belongs, and which actions need a person’s approval.
01 / CONNECTED RECORDS
Turn borrower information into the records, relationships, and documents that Vaster’s team uses to move a loan forward.
Submission creates or updates HubSpot contacts and deals, connects applicants, guarantors, co-guarantors, and brokers, and creates a listing for each subject property. Encompass imports bring existing loan information into the application, with missing fields surfaced for completion.
An update preserves an existing deal’s pipeline, stage, and close date. The application adds information without overwriting the lending team’s decisions.
02 / IDENTITY & CONSENT
Give staff a controlled way to use identity information, with evidence of the authorization behind it.
Dedicated SSN handling uses encrypted storage and masked values. Revealing an SSN requires credit authorization and a stated reason; the access result is recorded, and the displayed value hides again after 30 seconds.
Credit authorization creates a companion PDF with the disclosure version, acceptance time, and context. Staff can also record phone authorization through a dedicated workflow.
03 / SIGNATURES & DOCUMENTS
Connect signature collection to the application and the working CRM deal.
Box Sign receives a generated application with signature fields and invites applicants in parallel. Reminders and staff controls support follow-up, resending, and cancellation. When signing is complete, the system retrieves and stores the signed PDF, then attaches it to the linked HubSpot deal.
Existing signature requests can be reused, and completed callbacks are recognized so repeated deliveries can be skipped. The signed document has a defined destination.
04 / OSCAR + MCP
Oscar brings application tools into Slack, where Vaster’s operations team can find, review, and prepare a loan file in conversation.
Find applications by address, deal name, owner, status, or recency. Retrieve a staff review link or an existing application PDF.
Inspect a draft and check it against the application’s validation rules. Bring missing or inconsistent information back to the team.
Update a draft, attach an original Slack document to the right applicant, or generate a missing PDF—with approval for changes.

MCP also gives supported assistants a way to draft, validate, and attach documents to the same application. Work can continue in the browser for borrower review and signing.
Access is restricted to authorized operations staff. Changes and document attachments require approval. Borrower consent and lending decisions remain with people.
THE BORROWER EXPERIENCE
A guided application keeps the loan details, people, properties, and documents connected while the borrower works.
