THE GAP

The gap is already in your production.
It is simply hard to see.

Testing checks what can happen before production. Monitoring and observability read the health your systems report.

Both are essential. Neither can confirm the one thing that matters most: that a real customer completed the journey.

FROM THE CUSTOMER’S SIDE

But did the payment arrive?

Beneficiary outcome unconfirmed

System response ≠ customer completion

We call it the
Production Reality Gap.

That is the view we add: your customer’s actual experience, in live production. Closing this gap is the whole of what we do.

REAL, NOT SYNTHETIC

Other approaches approximate the customer.
We become one.

Scripted checks tell you whether the system responds as expected. We confirm whether the customer’s journey actually completes.

Real funded accounts. Real balances. Real authentication. In live production.

WHAT OUR CLIENTS SAY

HEARD IN THE CONTROL ROOMS WE SERVE

WTSS is playing an integral role in how Citi safeguards its clients when releasing new products and features. It’s not just internal testing — leveraging WTSS we can validate releases through the client lens, so they experience nothing short of excellence from day one.

ONE METHOD, TWO CHALLENGES

One method.
Two challenges it solves.

Find the one that is louder for you. We bring the same customer perspective to the day something changes and every day it runs.

A / BEFORE YOUR CUSTOMERS ARRIVE

Verify the change,
before your customers do.

For payment product, QA and platform leaders.

You are launching a product, migrating a platform or shipping a release. QA and UAT verify everything possible before go-live. We add the final step: the real customer journey in live production.

A clear go or no-go. Defects found before a customer finds them.

LaunchGuard + ChangeChecker

Citibank verifies new products, migrations and customer-facing changes with us before they scale.

B / WHILE YOUR SERVICE RUNS

The one signal your
observability is missing.

For observability, engineering and resilience leaders.

Every dashboard can be green while a customer cannot complete a payment. We run the critical journeys continuously, 24/7, and feed the customer’s actual perspective into your observability.

Where the journey broke, with timestamped logs, video and screenshots.

Our data runs live in a large European bank’s control room, supporting customer-journey control and faster detection.

Alongside your teams. Alongside your stack. The customer-side proof neither can produce on its own.

THE SAME METHOD, FURTHER

The same method, across almost anything a customer depends on.

The two doors are the common shapes. The method reaches further: payments and cards, onboarding and authentication, cross-border and FX, file transfers, a new payment-rail endpoint, feedback on developer documentation, merchant and customer in a single flow. One question every time: does the real thing work, in production, for the party who depends on it.

WHY YOU CANNOT SIMPLY BUILD THIS

Talent is not the hard part.
The infrastructure is.

The largest banks have the engineering talent to attempt this. What takes years to build is everything around it: the funded accounts, authentication robots and discipline to operate safely in live production.

Proprietary authentication

Human-to-machine and machine-to-machine robots, acting in real customer roles at scale.

Black-box by design

We observe what the customer experiences, with no internal knowledge of your systems.
