Build it yourselfvs Callvu
An internal build gives you full control, and with AI coding tools a working demo can appear quickly. But a regulated process in production needs much more than a demo: enforcement of every regulation on every step, updates every time a rule changes, integrations to the core and outside parties, and evidence of why each step was allowed, kept for examiners. Callvu delivers that as a product, built and maintained for you, live in a few weeks.

The fair version
What an internal build is built for.Sourced from their own pages.
An internal build automates a regulated process with your own team. Your engineers, increasingly with AI coding tools, build the intake screens, the workflow, the integrations to the core and other systems, the compliance checks and the logging for each process, and then maintain all of it as regulations, systems and policies change. General-purpose workflow and rules engines can shorten parts of the build, but the regulations, integrations and evidence trail for each process are still yours to write and keep current. It gives full control and fits processes that are unique to your institution.
When to choose which
Two different jobs.Pick the one you need.
When to choose an internal build
Choose an internal build when the process is unique to your institution, low in compliance risk and volume, and unlikely to change, and when you have engineering capacity to build it, integrate it and maintain it, including an evidence trail, for years. It also fits experiments and internal tools where no regulator will ask how a step was allowed.
When to choose Callvu
A demo is not production. The demo shows a form and a flow. Production needs every regulation and company policy enforced on every step, updated whenever a rule changes; integrations to the core, the loan system, policy admin or billing and to outside parties; documents chased and verified on a clock; human decisions recorded; and evidence of why each step was allowed, kept and ready for an examiner. An internal build must build and own each of these for every process.
Callvu delivers them as a product. It runs the whole process with five moves: it prefills from what the core already knows, classifies each request with work type, skill, effort and due date the moment it lands, chases and verifies documents from customers and outside parties on a clock, routes decisions to the Decision Desk, and writes the result back by API. A deterministic orchestrator runs every step, so AI never runs the process; Callvu Studio comes with most regulations already loaded as policies, and every run produces a Decision Trace and an Audit Trace, immutable and pushed in real time to your GRC and BI tools.
Choose Callvu, too, when time and ownership cost matter. Callvu's license includes white-glove design, implementation, maintenance and optimization for as long as it runs, with no engineering backlog to manage, and Callvu goes live in a few weeks: PSEG Long Island went live in 4 weeks, and Phoenix Insurance integrated all core systems in 4 weeks.
Side by side
The verifiable facts.Nothing else.
Every cell about Internal build is sourced from its own public pages. Runtime enforcement and the handoff lead the table because they are where the two differ most.
| Capability |  | Internal build |
|---|---|---|
| Primary role | Completion and Compliance Layer between every front door and the system of record | Custom software your team builds and owns for each process |
| 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; most regulations come already loaded as policies | Hand-coded per process; every regulation and company policy written and re-written by your engineers as it changes |
| Front-to-back-office handoff | Yes, end to end: prefill from the core, classify the work, chase and verify documents, route decisions to the Decision Desk and write back to the system of record | Prefill, classification, document chase, decisions and write back each built and maintained as custom code |
| Evidence for examiners | An immutable Decision Trace and Audit Trace for every run, pushed in real time to your GRC and BI tools | Application logs, unless you also build a separate evidence system |
| AI agents | Any AI agent, yours or Callvu's, can start a governed process; six evaluator agents assess every action and a deterministic orchestrator decides whether it runs | You design the controls for any AI you connect to your systems of record |
| Integrations | By API and webhooks, on top of existing systems: cores such as Fiserv, FIS, Jack Henry and Corelation, nCino and MeridianLink, insurance cores, EHRs, telco BSS, CRMs and contact center platforms such as NICE CXone and Genesys; more added per customer | Each integration built and maintained by your team |
| Deployment and maintenance | White-glove design, implementation, maintenance and optimization included in the license, for as long as it runs; live in a few weeks | Your engineering team for the life of the process |
