The short version
Gateless and Sei both automate the document-heavy core of mortgage underwriting: extracting data, calculating income, and clearing conditions against agency guidelines. If your goal is to clear underwriting conditions directly inside Encompass, Byte, or Empower, Gateless is a focused, well-integrated tool.
Sei runs more of the manufacturing line. Income is calculated for representation-and-warranty relief through Fannie Mae’s Income Calculator, conditions clear against the Fannie, Freddie, and FHA handbooks plus your overlays with source-document citations, and the same managed platform handles pre-underwriting, Closing Disclosure automation, pre-close and post-close QC, and borrower-facing voice.
WHAT GATELESS DOES
Gateless is a mortgage underwriting automation tool — its Smart Underwrite product extracts document data, calculates income, and auto-clears data-integrity checks and conditions inside the lender’s LOS.

Where Sei is different
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.
Cited, guideline-validated underwriting
Conditions clear against the Fannie Mae Selling Guide, Freddie Mac, and FHA Handbook 4000.1 plus your investor overlays — each item confidence-scored and cited to the source document, so reviewers handle only true exceptions.
Closing and QC built in
Closing Disclosure automation with TRID timing and fee-tolerance checks, plus pre-close and post-close QC with agency- and investor-ready audit trails — the same platform that originated and underwrote the loan.
Where Gateless fits
- Native integrations into Encompass, Byte and Empower for in-LOS condition clearing
- Strong automation of data-integrity checks on conforming and FHA files
- Document data extraction and automated income calculation built into the underwriting step
When Sei is the better fit
- You want income calculated for rep-and-warrant relief via Fannie’s Income Calculator
- You need cited condition clearing plus Closing Disclosure automation and post-close QC
- You want one managed platform from sales voice through servicing, not a single workflow
