5 products live in production
Fortilis, GDK-CRM, FTC, GDK Nexus, and Tavira are live, accept paying customers, and run on dedicated infrastructure. The product roster is documented and inspectable.
Customer stories worth telling, only when they're true.
We publish customer references with verifiable attribution and concrete outcomes. When a customer prefers privacy, we honor that. When we do not have a verifiable metric, we do not invent one. This page grows when our customers say it can.
The longest-running case study is GDK Digital itself
Every product in our portfolio is used inside GDK Digital. The CRM tracks our pipeline. The credential manager protects our team's secrets. The team-communications tool runs our internal projects. The Nexus QR layer powers our event capture. When you ask "does this work?" the most honest answer is "we run our business on it."
Customer stories
We publish customer stories with verified attribution. Stories appear here as customers approve them.
Why this section is short by design
Many SaaS sites publish unattributed quotes, unverified metrics, and customer logos they have not earned permission to display. We choose not to. If you are evaluating a GDK Digital product and want a real reference conversation, contact us and we will introduce you to a customer in your industry where we have permission to do so.

How a reference conversation works
- You ask. Use the contact form and tell us which product you are evaluating and what your situation looks like.
- We match. We find a customer in your space (or as close as we have) where the use case overlaps and where we have permission to make an introduction.
- The introduction is double opt-in. The customer agrees in advance. You get a real conversation, not a sales pitch.
- If we cannot match you, we say so. We won't pretend we have a reference we do not have.
Frequently asked questions
Why aren't there more named customer logos on this page?
We only publish customer names, logos, and quotes when the customer has granted explicit written permission. Some customers prefer to stay off public reference pages, and we respect that. We would rather show fewer names you can trust than a wall of unverifiable logos.
Are the metrics on this page real?
Every quantitative claim on this page comes from a specific customer engagement we can attribute. If we did not have a verifiable source, we did not publish a number.
How does GDK Digital handle a customer reference request?
If you are evaluating one of our products and want to talk to an existing customer, reach out through the contact form. We will introduce you to a customer in your industry where we have permission to do so.
Can my company be featured here?
Yes. If you are an active GDK Digital customer and want to share what you have built, email info@gdkdigital.com. We will write the case study with you (not at you) and you will approve every word before it ships.
Does GDK Digital use its own products?
Yes. We operate the CRM we sell, the credential manager we sell, and the team-communications tool we sell. Our own internal use is documented on the About page and serves as the longest-running case study for each product.
