"I see the CX gaps a business misses — and I show where the money is hiding inside them."
dthink is Ilya Chadin's bureau.
I work on the floor personally — mapping the customer journey, talking to teams, and checking what actually changes after we leave.
Common gaps
This is what we most often find in stores and in data. Sound familiar?
Clients don't come back — or come back too slowly
In many retail and HoReCa projects up to 80% of clients never return.
Clienteling →20% of clients drive most of your revenue — but you work with them like everyone else
Most businesses have no retention or development program for key clients: no tracking, no segmentation, no deliberate return path.
Clienteling →Research and reviews turn into documents, not actions
NPS gets calculated, reports get sent — and nothing changes on the shop floor.
CX Design →Automation serves the process, not the client or the employee
AI and CRM speed up operations but don't strengthen trust.

Clienteling — a culture of client relationships
One product, three ways in. We move conversion, basket size and repeat purchases.
Diagnostic & strategy
Two sessions and the analysis in between
- –we go into your numbers: revenue, conversion, churn, the cost of a lost client
- –we build the analysis and walk you through it at the second session
- –you leave with a 90-day plan your team can run itself
We start with a short conversation: what the task is and whether we fit. It costs nothing and it is not the analysis itself.
Implementation
Project or ongoing support
- –we go into the field: shifts, chats, the shop floor
- –we rebuild scenarios, roles and metrics together with your managers
- –we stay until the team holds the rhythm without us
A different level of responsibility: we answer for metrics moving, not for a plan being written.
Clienteling course
Two learning tracks
- –two tracks: for the owner and for the retail director
- –we work on your data, not on cases from books
- –you leave with roles, scenarios and KPIs for your team
For teams that want to build the system themselves.
When you already know the task
Rebuild the customer journey, bring in AI, or work through a problem with your team — you can start with the specific job right away.

Telegram: short field notes from live projects and reactions to the industry. Blog: long-form pieces on service, clienteling, and AI — no fluff.

Deep dives & playbooks
Long-form pieces on how we look at CX, clienteling, and AI — and what we actually do inside projects.
Two quick checks — pick where to start
A view of your service from the outside: where clients don't come back, where the team works by hand, where CRM doesn't help, and where a system is already in place.
Money is leaking — every day, in every shift.
Clients don't come back, repeat sales don't happen, NPS gets counted and nothing changes on the floor. We show you where your leaks are — and what to do about them in the next 90 days.
