The journey in four steps

01

Connect

The platform plugs into your rails, accounts and cards. No multi-year project.

02

Contract

A digital file for your business clients: onboarding, contract and KYC in a single flow.

03

Understand

Scoring based on your portfolio's real operations, not on self-reported data.

04

Launch

Financial products on top of B2B flows, with your brand and your pricing.

In weeks, not years

The platform adapts to the rails your bank already has

Doesn't replace the core

The platform connects; the core stays where it is.

No migration required

Accounts and cards remain the bank's.

No vendor changes

Works alongside the vendors the bank already has.

API on existing rails

An orchestration layer, not a replacement.
DESIGN PRINCIPLE

Neutral
by architecture.

That neutrality isn't a sales promise: it's the very architecture of the solution.

“Speed without infrastructure risk.

Every integration into the core banking system means a committee, a pentest and a deployment window. Callao Empresas stays out of it: it runs on the layer the bank already exposes.

It isn't a technical limitation. It's why the project goes live in weeks.”
