Before the first call
What makes Banking hard

The problems we design around.

01

Legacy cores

Modern apps still have to talk to decades-old core banking systems.

02

Onboarding drop-off

Every extra screen in account opening costs customers.

03

Security without friction

Strong authentication that customers do not hate.

Why Mariox for Banking

Built for how Banking actually works.

01

Domain first

We map banking workflows, users and regulations before design starts, so the product fits how the business already runs.

02

Compliance in the architecture

Requirements such as PCI DSS and ISO 27001 are built into data models, access and audit logs from the first sprint.

03

Senior engineers only

The people who scope your banking product are the people who build it. No juniors behind an account manager.

04

Built for peak load

Load testing, caching and monitoring are planned for the moments banking traffic spikes, not after launch.

05

You own everything

Code, cloud accounts and documentation sit in your name from the first commit.

Cloud

Secure, auto-scaling infrastructure on AWS, Azure or Google Cloud, with data kept in the region you need.

03

Data & analytics

Pipelines and dashboards that turn banking operations data into decisions leadership trusts.

04

Automation

Manual handoffs, approvals and data entry replaced by workflows that log every step.

05

IoT & devices

Sensors, scanners and devices connected to your systems where physical operations matter.

06

Blockchain

How a Banking project runs.

011–2 weeks

Discover

Workflows, users and banking requirements mapped with your team.

021 week

Scope

Architecture, compliance needs and a fixed estimate you can plan around.

03Sprints

Build

Two-week sprints with a working demo at the end of every one.

04Ongoing

Launch & run

Release, monitoring and a team that stays for what comes next.

Ways to work

Three ways to start.

Most clients begin with discovery, then keep the same people on as a dedicated team.

012–4 weeks

Product discovery

Map what to build, the risks and a fixed estimate before committing to the full build.

02Fixed scope

Build & launch

Two-week sprints with a demo every time, through release and handover.

03Monthly

Dedicated team

A senior squad that works only on your banking product, scaling up or down by the month.

Banking, answered.

It depends on scope. Most first releases fall between $25k and $150k. After a short discovery we give a fixed estimate, so the number holds.
