Meet Vyndarix
Fraud and financial-crime defence in one engine
Most institutions run fraud and AML on separate tools that never share what they know. We built Vyndarix so every team works from the same understanding of each customer.
Behavioural profiling
Builds a picture of each customer, device and account, then flags activity that breaks the pattern, including patterns nobody has seen before.
Behavioural intelligenceInline decisions
Approve, hold or block inside the payment flow itself, so prevention happens before funds leave the account.
Payment fraud detectionNetwork analysis
Connects accounts, devices and payees to surface coordinated rings and the mule accounts that feed them.
Fraud ring detectionCasework and reporting
Alerts land in prioritised queues, and suspicious-activity reports are drafted from evidence already gathered.
AML complianceScam interception
Spots the signs of social engineering, like a new payee under pressure, and warns the customer before they send.
Scam detectionFraud and AML together
Fraud and financial-crime teams share one view of risk instead of reconciling two systems.
FrAML convergenceExplainable by design
A person can always check the machine’s work
When Vyndarix holds a payment, the analyst sees what triggered it: an unfamiliar payee, a link to known mule accounts, a device doing something unusual. Nothing is a black box, which matters when a regulator asks why.
How decisions are auditedOur approach
What four years of building taught us
Rule-based systems only catch what someone has already seen. These are the ideas we keep returning to as we build something that doesn’t have that limit.
- 01
Normal is personal
A £5,000 transfer is routine for one customer and alarming for another. One threshold for everybody guarantees both missed fraud and angry good customers.
- 02
Decide inside the payment
A check that runs after money has moved is a report, not prevention. We engineer to a latency budget measured in milliseconds.
- 03
Every score must explain itself
Analysts need to know what to look at, and regulators need to know why. A number without reasons is hard to act on and harder to defend.
- 04
Rules still have a job
Policy limits and regulatory controls belong in rules. Spotting a fraud pattern that appeared last Tuesday does not.

About StreamFlux
An engineering company first
StreamFlux began as a research effort more than four years ago, around one question: how quickly can you make a decision about live financial data that people can trust?
The answer became Vyndarix. In 2025 we incorporated Stream Flux Ltd in London to bring it to market, and we still design, build and operate every part of it ourselves.
