About Us

Built by people who have been there.

We knew there had to be a better way.
So we built it.

Realta started on your side of the screen.

Our team brings deep expertise in fraud prevention, AML, payments, product development, engineering, and machine learning. 

Because we have done the work ourselves.

We have spent hundreds of hours onboarding merchants. Investigating suspicious activity. Juggling too many tabs and systems that did not talk to one another.

So we know exactly what happens when data, teams, and decisions are disconnected—and what’s possible when they work together.

Why we chose the name Realta.

The name Realta comes from the Irish word for "star." 

It is also our purpose: to bring clarity to an industry filled with complexity, where risk teams work with disconnected systems, incomplete information, and black-box logic.

In our logo, the star becomes a portcullis, a symbol of security and control.

Together, they capture what we offer: greater visibility, hardened security, and better decisions.

Built in Ireland. Designed for a global risk landscape.

Ireland has become one of the world’s leading financial technology hubs, bringing together expertise in payments, financial crime, software engineering, and data science.

While our main office is in Ireland, our team, experience, and perspective are global. We work across markets and regulatory environments to help organizations address increasingly complex risk challenges.

Deep expertise. Multiple disciplines. Proven results.

Our global team brings deep experience in risk, fraud, payments, engineering, product development, machine learning, and the U.S. intelligence community.

Together, we bring more than 80 years of experience in machine learning, 200+ years in fintech, and 260+ years in product development and delivery.

We also bring results.

A few examples of what we delivered before we came together to build Realta:

Alerted financial institutions to millions of stolen payment cards

Helped fast-track legitimate approvals while cutting chargebacks and generating millions in additional revenue

Dramatically reduced false-positive AML alerts

Built data pipelines that saved teams hundreds of working hours each year

We bring everything we have learned solving complex risk problems to Realta—and to your team.

A few other results we delivered along the way:

Found 30 million stolen payment cards, before they were used for fraud.

+

We created (and patented) technology that uses deep neural networks to uncover compromised cards on the Dark Web and alert financial institutions before the fraud could even begin.

Approved more legitimate transactions while cutting chargebacks by 82%.

+

We built machine-learning models and real-time scoring that dropped chargebacks by 82% and transaction declines by more than 50%, helping one enterprise client generate $136 million in additional revenue.

Cut false-positive AML alerts by 40%.

+

We engineered a high-speed AML system that completes complex screens in under 50 milliseconds and delivers 40% fewer false positives.

But wait, there’s more!

+

We have also created dashboards that bring fragmented data into a single investigative view, built data pipelines that save hundreds of working hours, and even helped law enforcement trace financial footprints to bring multiple missing children home safely.
