From HKZ Digital Corporate
Customer relationships need more than another campaign.
CRM foundations
Get scattered customer data into one governed place your team can trust and use.
Operational enablement
Connect the systems, fix the work around them, and leave your team with the training and documentation to keep going.
A small team with deep experience
Over 30 years across both sides of customer engagement.
HKZ Digital is two people, Hollie and Kai Zeyher. Between us we have over 30 years in CRM, email, SMS and digital platforms: as consultants, as the people doing the implementation, and running these channels in-house.
Before founding HKZ Digital, we directed lifecycle and retention programs from the inside at major national brands—including Hertz, Academy Sports + Outdoors, and Chico’s FAS. We understand both sides: designing and implementing the systems, and being accountable for the customer experiences they power every day.

Complex systems should feel human on the other side.
We do not only advise teams on complexity. We build inside it.
We build Divergent Echoes with AI agents, so we meet the hard parts ourselves: keeping an agent on track over months, splitting work into pieces it can finish, checking what it produces, and handing work between people and agents.
Our clients get what we learn there. Each project should also leave your team more capable, with clearer systems, documentation people will use, and training that stays with them.
Beyond the prompt
We learned agentic workflows on our own product, not on your customer data.
Kai has spent more than 500 hours building Divergent Echoes with AI agents. The surprise was that the building got fast and the deciding did not.
We wrote down what that looked like: three drafts of one enemy, the notes that hold the project together, what it cost, and what it changed about our client work.
