The short version
Saris and Sei both use agentic AI to automate document-heavy lending work: intake, extraction, validation, and system updates with full audit trails. Saris focuses on the back office for banks and credit unions, delivered through a native desktop app with a human-in-the-loop model.
Sei shares that document-and-workflow core and adds the borrower-facing layer plus full mortgage manufacturing. The same managed platform runs speed-to-lead and servicing voice, calculates rep-and-warrant-eligible income, underwrites with cited conditions, automates the Closing Disclosure, and clears post-close QC. For bank and credit-union clients, Sei also offers fincrime alert reviews where they’re relevant.
WHAT SARIS DOES
Saris builds agentic AI that automates back-office lending and operations workflows — document intake, data extraction and validation, compliance checks, and system updates — for banks and credit unions.

Where Sei is different
Voice across the whole lifecycle
Speed-to-lead and 24/7 inbound sales agents, loan-officer appointment booking, and FDCPA-compliant servicing and collections — borrower conversations from first contact through payoff, on one platform.
Rep-and-warrant-eligible income
Income is calculated across W-2, self-employed (Schedule C, K-1, S-corp, 1099), rental, and retirement income, with Fannie Mae Income Calculator integration — so eligible calculations earn representation-and-warranty relief and lower repurchase risk.
Fully managed, end to end
Sei builds, deploys, and runs the agents and workflows for you — from the first sales call through underwriting, closing, and post-close QC. You get outcomes, not a toolkit to configure, typically live in weeks.
