SimpleNexusvs Callvu

SimpleNexus is now nCino Mortgage, a mobile-first mortgage point of sale with borrower and loan officer apps, document validation and automated disclosures, synced to a loan origination system such as Encompass. Callvu is the Completion and Compliance Layer behind it: it runs conditions, outside-party documents, approvals and servicing requests end to end to the loan system and the core, deterministically, with compliance enforced at every step. The point of sale captures the borrower; Callvu completes everything that follows.

The fair version

What SimpleNexus is built for.Sourced from their own pages.

nCino agreed to acquire SimpleNexus in 2021 ^[2] and rebranded it as part of nCino in 2023 ^[1]; it is sold today as nCino Mortgage. In the US it is a mobile-first point of sale with a borrower app, pre-qualification, a Spanish-language application and mobile eSign, plus loan officer tools and partner visibility ^[3]. Document AI validates uploads and extracts data into the loan system, and closing documents are checked for compliance ^[3]. In 2026 nCino added a loan officer productivity suite with automated disclosures and pre-approval ^[6], a Mortgage MCP that lets lenders connect their own AI agents within existing permissions, with every action logged ^[5], and third-party origination support ^[4]. Loan officers send document requests to borrowers ^[8], and the application syncs two ways with Encompass ^[7].

When to choose which

Two different jobs.Pick the one you need.

When to choose SimpleNexus

Choose nCino Mortgage when the priority is a mobile borrower application experience and loan officer engagement at the point of sale ^[3], with document validation and automated disclosures ^[6], synced to your loan origination system ^[7].

When to choose Callvu

Choose Callvu when the work after the application is where time goes: conditions from title, appraisers, employers and other outside parties, approvals, servicing requests and the write back. Callvu orchestrates that work, routes it by work type, skill and due date, applies rules and policies and manages every decision, with five moves: it prefills from the loan system and the core, classifies each request the moment it lands, chases and verifies documents from borrowers and outside parties on a clock, routes approvals to the Decision Desk, and writes the result back by API.

Guardrails are not runtime enforcement. nCino Mortgage's AI validates documents ^[3] and sends disclosures ^[6], and lenders' own agents can update borrower records, trigger verifications, run automated underwriting and draft disclosures within their permissions, with every action logged ^[5]. Guardrails limit and record what an AI does while it does the work. Even with guardrails, an AI that runs a step can write wrong data to the system of record, take a path that is not in the workflow, or act compliantly most of the time rather than every time. Callvu does not let AI run the process. A deterministic orchestrator executes every step of a defined workflow and enforces every control before the step runs; AI only starts a process or evaluates it. Every run is recorded in a Decision Trace and an Audit Trace.

Side by side

The verifiable facts.Nothing else.

Every cell about SimpleNexus is sourced from its own public pages. Runtime enforcement and the handoff lead the table because they are where the two differ most.

Capability		SimpleNexus
Primary role	Completion and Compliance Layer between every front door and the system of record	Mortgage point of sale (borrower and loan officer apps), now part of nCino ^[3]
Runtime compliance enforcement	Yes. A deterministic orchestrator runs every step; AI never runs the process. Every regulation and company policy is enforced on every step while the work runs, whether a person or an AI started it; a step that fails a control does not run. A Decision Trace and an Audit Trace for every run	Partial. Closing documents are validated for compliance and Document AI flags exceptions for human review; AI agents act within user permissions, with every action logged and human confirmation available for higher-impact actions. Not documented: a policy layer that enforces every regulation and company policy on every step after the application, with a step that fails a control stopped before it runs ^[3]
Front-to-back-office handoff	Yes, end to end: prefill from the loan system and the core, classify the work, chase and verify documents from borrowers and outside parties on a clock, route decisions to the Decision Desk and write back by API	Loan officers send document tasks to borrowers; the application syncs two ways with Encompass ^[8]
AI guardrails vs deterministic execution	Deterministic execution, not guardrails: AI never runs the process. A deterministic orchestrator executes every step and enforces every control before it runs, so nothing unchecked reaches the system of record and no step outside the workflow can happen	Mortgage MCP lets lenders' agents act within existing permissions, with every action logged and configurable human approval for higher-impact actions ^[5]
Loan origination system	Integrates with Encompass, MeridianLink, nCino and other lending systems, and with the core	Syncs to an external LOS such as Encompass ^[7]
Servicing	Runs servicing requests end to end and writes back to the servicing system and the core	No servicing capability documented ^[3]

Using both together

Keep what works.Add the layer that finishes it.

nCino Mortgage stays the borrower and loan officer experience. Callvu runs the governed process after the application, conditions, outside-party documents, approvals and servicing requests, and writes back to the loan origination system and the core by API, with every step enforced and recorded.

FAQ

The questions buyers ask.Answered plainly.

Does SimpleNexus (nCino Mortgage) enforce compliance at runtime?

Partly. nCino Mortgage validates closing documents for compliance, sends standard disclosures automatically and limits AI agents to the user's permissions with every action logged and configurable human approval for higher-impact actions. Those are checks inside the point of sale and guardrails on AI. It does not document a policy layer that enforces every regulation and company policy on every step of the process after the application. Callvu does, and AI never runs the process: a deterministic orchestrator does.

Is SimpleNexus still a product?

SimpleNexus was acquired by nCino and rebranded in 2023; it is sold today as nCino Mortgage. In the US it is a point of sale that syncs to a loan origination system such as Encompass.

What do lenders still need after a mortgage point of sale?

The point of sale captures the application. Conditions from outside parties, approvals, disclosures follow-up, servicing requests and the write back to the loan system and the core still need to run end to end. Callvu runs that work with documents chased on a clock, decisions in the Decision Desk and every step enforced.

Can Callvu work with nCino Mortgage?

Yes. Callvu integrates with nCino and with the loan origination system behind it. The point of sale stays the borrower experience; Callvu runs the governed process after the application.

How fast can Callvu go live?

Callvu designs, implements and maintains the process for you, included in the license. A proof of value on one of your own processes comes first: 4 to 10 weeks, with two gates, completion and compliance.
