Sei

Sei runs UMOS (Unified Mortgage Orchestration System), a platform of AI agents covering mortgage origination and servicing workflows. Agents handle borrower conversations, document intake, income calculation, condition clearing, TRID timing, pre-close QC, call monitoring, loan boarding, escrow, collections, loss mitigation and claims. Agents work against a version-controlled rulebook of agency guidelines, investor overlays and internal SOPs, and write results back into the lender's existing LOS.

UMOS is organized into sixteen desks: eight for origination (Loan Officer Assistant, POS, Document Concierge, Income Desk, Conditions Manager, TRID & Cure Management, Pre-Close QC Agent, Compliance Agent) and eight for servicing (Loan Boarding, Escrow Manager, Collections, Default Management, Loss Mitigation, Claims Analyst, Payoffs Manager, Compliance Manager). Core capabilities include document intelligence, voice agents for compliant borrower calls, and call monitoring with scorecards. The platform integrates with LOS systems such as ICE Encompass, Calyx and MeridianLink, and connects to CRM and telephony stacks including Salesforce, Genesys, RingCentral and Twilio. Agents hold goals over long horizons, re-plan as files change, and escalate to human review below a configurable confidence floor, with an evidence trail logging every decision.

Sei is built for mortgage lenders and servicers. Deployment is handled by Sei's team with onboarding, policy ingestion and integration setup, including custom integrations. The pages do not specify pricing structure or plan tiers.
