Comparison · Voice Agents
Genesys is the enterprise contact-center platform you build and configure on. Sei is a fully managed mortgage platform that runs on top of Genesys — borrower voice plus underwriting, closing, and QC.
The short version
Genesys and Sei are more complementary than competitive. Genesys is the contact-center infrastructure — omnichannel routing, IVR, workforce engagement, and AI copilots — deployed across enterprises in every industry. Sei integrates with Genesys rather than replacing it.
Genesys gives you the telephony layer and the tools to build on it. Sei delivers a fully managed mortgage operation on top of it: speed-to-lead and inbound sales agents, loan-officer appointment booking, FDCPA servicing, and 100% call QA against TILA/RESPA/TRID. It also manufactures the loan, with income calculation carrying Fannie Income Calculator rep-and-warrant relief, cited underwriting, Closing Disclosure automation and post-close QC.
The frame
Most of the vendors on this page automate one step. The question that decides the buy is what happens when that step is done: a tool hands its output back to a queue, and someone has to pick it up. A desk holds the goal until it is reached, and tells you where it stopped.
Extraction, or an application form, or a review pass. It runs when someone runs it, and hands the result to the next queue.
It holds a goal across weeks, wakes when the loan moves, re-plans when the file changes, and escalates by name when it is below its confidence floor.
So there is a reconciliation step, and a version of the file only one vendor can see.
A condition created by underwriting is visible to the document desk in the same instant, because there is only one of it.
Eight vendors, eight handoffs, and the cycle time lives in the gaps between them.
Lead call to clear-to-close, boarding to payoff, against one version-controlled rulebook.

“Not published” means exactly that: we could not find it stated publicly. It is not a claim that the capability or certification is absent.

What those rows mean
Sei builds, deploys and runs the agents and workflows for you — from the first sales call through underwriting, closing and post-close QC. Managed means Sei runs the system, not that a services team works your files behind it. Every decision is machine-made, confidence-scored and cited, and the automation rate is a number you can hold Sei to.
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.
Conditions clear against the Fannie Mae Selling Guide, Freddie Mac and FHA Handbook 4000.1, plus your investor overlays. Each item is confidence-scored and cited to the source document, so reviewers handle only true exceptions.
The case for Sei
No — Sei integrates with Genesys. You keep your contact-center platform and add Sei’s mortgage-specific voice agents, call QA, and loan manufacturing (underwriting, income, closing, QC) on top.
Genesys’ AI is general-purpose and configured by you. Sei’s agents and QA come pre-trained on FDCPA, TCPA, TILA, RESPA, TRID, UDAAP and Fair Housing, and tuned to mortgage workflows. You get a compliant, managed outcome — typically live in weeks — without building it yourself.
Income calculation with Fannie Income Calculator rep-and-warrant relief, cited underwriting against agency guidelines and overlays, Closing Disclosure automation, and pre/post-close QC.
Yes. Sei is SOC 2 Type II and PCI DSS Level 1 certified, runs in private VPCs with per-customer sandboxing, and never trains on your data.
Gateless automates underwriting condition clearing inside your LOS. Sei runs the file end to end — pre-underwriting through post-close QC — fed by borrower-facing voice agents.
