Financial services

Machine learning that catches what rules miss

We build fraud, credit, and document systems for banks, insurers, lenders, and exchanges, trained on your data and run in your environment.

Capabilities

What we build

01

Fraud and AML detection

Models that catch fraud, money laundering, and suspicious transactions that rules miss, and keeps catching them as behaviour changes.

Proof
OVEX, 98% of fraud caught, with 99% fewer false alarms.
02

Credit and risk

Scoring and approval models built on transaction and credit bureau data, with the explanations your credit committee and regulator need.

Proof
For Shoprite's micro-lending business, about 20% saved on credit bureau costs by declining unlikely applications before the bureau call.
03

Document and knowledge systems

Extraction from statements, claims, and financial reports into a checked data layer that records the source of each fact, so answers can be traced and audited.

04

Agentic workflows with people in the loop

Agents that prepare the work (a case file, a reconciliation, a draft report) and hand the decision to a person, with language-model usage and its cost visible and capped.

05

Sovereign and small-model AI

Fine-tuned small models that match large general-purpose models on your specific task, running on your own infrastructure, with your data kept in South Africa.

06

AI strategy

Senior practitioners who help your leadership choose use cases, set realistic cost and accuracy targets, and build the internal capability to run them.

Why financial institutions choose us

Built for regulated environments

Explainable by design

Each score comes with the reasons behind it. Where a decision must follow fixed, auditable rules, we derive those rules from the model.

Your data stays yours

Systems run in your cloud or on your hardware. You own the code, the models, and the documentation. You pay no per-seat or per-query licence fees.

People stay in control

Investigators, analysts, and credit officers decide; the system ranks cases, explains its scores, and drafts case files and reports for them to check.

Local and senior

We are a South African team in your time zone, led by people who have built production machine learning since 2014.

The cost of AI

AI that costs less to run as it is used more

Renting a general chat model looks cheap at the start and grows more expensive with every question your staff ask. We engineer the data the model reads, pick the most efficient and effective model for the accuracy target, and put it on infrastructure you control, so the cost per answer falls as use grows.

OVEXCase study

Sequence learning for fraud detection on a crypto exchange

OVEX's rules caught three quarters of fraud and raised alarms that were mostly false. We replaced them with models that read the order and timing of each account's activity.

We trained two models on OVEX's history, one on how fraudsters behave and one on how honest customers behave, and the system flags an account when it looks more like the first. Now in production, the system includes a dashboard that shows investigators when an account's behaviour changed.

Engagement

How an engagement starts

01 · Four to eight weeks, fixed fee

Readiness assessment

We review your data and goal and deliver a readiness report, a workshop with your team, and a delivery plan.

02 · Fixed scope or monthly fee

Build and validate

We build a working model and measure it against your own KPIs. You then decide whether to go on.

03 · Renewable retainer

Production and improvement

We deploy, integrate, and keep the models current, and train your team to run them.
