CRM & lifecycle architecture
Plan what a customer hears from you from first contact to win-back, then build it so each stage hands off cleanly to the next.

Systems you can run.
Automation you can explain.
Most customer journeys break in the handoffs between marketing, data, and CRM. We untangle the architecture, build the journeys, and eliminate the messy manual work—then make sure your team can run them without us.
Two veteran operators with over 30 years leading channels in-house and consulting for complex, regulated brands. From HIPAA compliance in healthcare to high-volume enterprise retail: no junior account managers, no endless retainer traps—just systems built to last.

The CEO’s Right Hand
Connected systems. Capable teams.
Make the operation easier to see, run, and improve.
Four kinds of work. Most projects start with one and end up touching the others.
Data governance & privacy
Set rules your team can follow for whose record it is, what they agreed to, and who may see it. We have worked under HIPAA and GDPR.
Integration & operations
Get your platforms passing the right data to each other, and fix the manual steps where work gets stuck between teams.
Agentic workflow enablement
Put AI agents to work where they help: on defined tasks, with checks on what they produce, a person reviewing what matters, and training for your team.
Why HKZ Digital?
Build useful capability, not permanent dependency.
The aim of every project is that you need us less at the end of it.
We design systems, not campaigns
A campaign ends. We build the parts that keep running after it: the data, the journeys and the rules they follow.
Trust is designed in
Privacy, consent and the regulations that apply to you are requirements from the first day, not a review at the end.
CRM is the foundation
A CRM should tell you what to do next, not only hold records. We get scattered customer data into one place your team trusts.
Clarity over cleverness
Plain messages, automation you can explain, and results you can measure.
Small team. Deep experience.
Like another member of your team.
HKZ Digital is two people, Hollie and Kai Zeyher. Between us we have over 30 years leading CRM, email, SMS, and digital platforms—directing enterprise channels in-house at Academy Sports + Outdoors, Hertz, onPeak (GES), Coding Dojo, and Chico’s FAS, alongside consulting for regulated healthcare and global enterprises.
We have built these systems, and we have been the ones answerable for what they send every day. Kai leads your Upwork engagement directly, with any additional team involvement agreed as part of the scope. There is no account team in between.
When we finish, your team should know what was built, why it works, how to check it, and where to take it next.
