Sei AI vs Tidalwave: The Borrower POS and the Managed Loan Behind It

AI at the front door, and AI running the loan

AI is reshaping mortgage from the borrower's first interaction through funding. Tidalwave and Sei AI focus on different parts of that journey, and both are strong — which is exactly why they can complement each other.

Tidalwave's SOLO is a borrower-facing, agentic point-of-sale experience. Sei AI is a fully managed platform that runs the lender's side of the operation — from sales voice to post-close QC — and integrates with the POS you already use. Here's the product comparison, in mortgage terms.

What Tidalwave brings

Tidalwave's SOLO is an agentic-AI mortgage point-of-sale experience focused on the borrower:

• A conversational application assistant that guides borrowers through applying
• Multilingual support that broadens accessibility
• Real-time verification of income, employment, and assets at application
• Document assistance that checks borrower uploads as they go
• Integrations with agency tools and data providers

For lenders that want a fast, modern, borrower-facing application experience, Tidalwave offers a polished point-of-sale product.

What Sei AI brings — the lender's side, managed end to end

Sei automates the work that turns an application into a funded, salable loan:

Sales voice that feeds the pipeline

• Speed-to-lead outbound, 24/7 inbound, mortgage-specific qualification, and loan-officer appointment booking directly into LO calendars.

Loan manufacturing

• Income calculation across W-2, self-employed (Schedule C, K-1, S-corp, 1099), rental, and retirement income, with Fannie Mae Income Calculator integration for representation-and-warranty relief.
• Underwriting against the Fannie Mae Selling Guide, Freddie Mac, and FHA 4000.1 plus overlays, with confidence-scored, source-cited condition clearing.
• Closing Disclosure automation with TRID timing and fee-tolerance checks.
• Pre-close and post-close QC with agency- and investor-ready audit trails.

Servicing and QA

• FDCPA-compliant servicing voice and 100% QA of LO and servicing calls against TILA, RESPA, TRID, UDAAP, and Fair Housing.

The bigger picture: complementary, with Sei running operations

A great application experience still has to be underwritten, closed, QC'd, and serviced. Sei integrates with your POS and LOS and manages everything from the sales call to post-close QC — so the borrower-facing front door and the operational back end both get AI.

How to think about the choice

• If your priority is a borrower-facing application and point-of-sale experience, Tidalwave is a strong, modern choice.
• If you want to manage the lender's operation — sales voice, underwriting with rep-and-warrant-eligible income, closing, QC, and servicing — on one platform, Sei AI is purpose-built for it, and integrates with the POS you already run.

Why mortgage lenders choose Sei AI

Sei runs the operation behind the application: rep-and-warrant-eligible income, cited condition clearing, Closing Disclosure automation, post-close QC, and borrower voice — all managed, all tuned to mortgage, live in weeks, SOC 2 Type II and PCI DSS Level 1 certified, and never training on your data.
