01 — At a glance

The story in one line

Staycity's guest messaging stopped being a queue to answer and became work that gets done.

Staycity Group operates aparthotels across Europe under the Staycity and Wilde brands. Guests reach out constantly — before booking, before arrival, mid-stay — across WhatsApp, website chat, email and OTA inboxes, in more than a dozen languages and from over ninety countries. D3x sits inside that flow and does the work: not a chatbot that answers, but an orchestration layer that resolves requests and executes them in Staycity's operational systems.

01B — The company · Two brands, one ambition

Europe's fastest-growing aparthotel group — scaling fast, staying lean.

Founded in Dublin in 2004, Staycity Group operates two complementary brands serving business and leisure guests staying a night, a week or a year.

+20 by 2030

Twenty new locations by 2030 — the fastest-growing aparthotel chain in the EU.

An aggressive European pipeline. The question every scaling operator faces: how do you serve more guests, in more places, without ballooning cost?

The operating principle

Grow the estate. Hold the headcount.

Staycity is scaling toward 20 additional properties while keeping its Dublin HQ team flat — no new central hires to absorb the growth. That only works if each new property arrives with capacity built in. D3x is that mechanism: as the estate grows, guest conversations are absorbed by the same AI layer rather than by new coordinators, agents or night staff. The 55% autonomy rate is the unit economics of expansion.

02 — The challenge · Before D3x

A single guest inbox, pulling in every direction at once.

Extended-stay guests behave differently from hotel guests. They ask more, over longer windows, and expect a fast, human-quality answer at any hour. For Staycity, that demand landed simultaneously across WhatsApp, website chat, email and OTA inboxes — each a separate tool, each a separate queue.

The hard part was never writing a reply. It was that a real answer often required doing something: raising a housekeeping task, logging a maintenance fault, checking a booking, correcting an invoice. A conventional chatbot could acknowledge the request. It couldn't complete it — so the work still fell to on-property teams, at all hours, in every language a guest happened to write in.

Chatbots answer. D3x resolves.

Staycity didn't need faster acknowledgements. It needed guest requests turned into completed work — inside the systems the property teams already run on.

  • Fragmented channels

    Four inboxes, no single view of the guest.

  • Round-the-clock demand

    A third of website conversations arrived outside staffed hours.

  • Multilingual load

    Guests writing in 14 languages from 91 countries.

  • Answers that needed action

    Replies alone left the operational work undone.

03 — The solution · D3x in the loop

One layer over every channel — that closes the loop, not just the message.

D3x unifies Staycity's guest channels behind a single AI layer, then wires that layer directly into the tools property teams use to get work done. A request doesn't stop at a reply — it becomes a task, a ticket, or a resolved answer, automatically.

  1. 01

    Unify the channels

    WhatsApp, website chat, email and OTA inboxes converge into one AI-orchestrated flow, with full guest context carried across all of them.

  2. 02

    Resolve the request

    The AI understands intent in the guest's own language and answers end-to-end — or drafts for a human when judgement is needed.

  3. 03

    Execute the work

    Where action is required, D3x creates the task directly in Optii or Snapfix — housekeeping, maintenance, ops — no re-keying.

A request that used to sit in an inbox now arrives as a task the team can action — in the system they already work in.

Connected systems

Optii

Guest requests become live housekeeping & service tasks across 29 connected properties.

Snapfix

Maintenance issues raised straight into the property's fault-tracking workflow. Newly connected at Tivoli and Liverpool Waterfront this month, with a clean rollout.

04 — The impact · Autonomy & scale

The AI majority: 55% of conversations, start to finish, without a human.

More than half of all guest conversations in June were resolved entirely by AI — a five-point rise month-on-month. Across every message sent to guests, AI wrote the clear majority.

Properties wired into operational tooling resolve autonomously 10 points more often (56% vs 46%) — evidence that D3x's advantage compounds the deeper it's integrated.

30% of web chats came in after hours.

682 website conversations arrived outside staffed hours — and were answered anyway. Coverage doesn't clock off.

04 — The impact · Work done & satisfaction

Conversations became completed work — at satisfaction guests actually rate highly.

The point of resolving isn't a tidy transcript — it's operational work getting done. In June, D3x turned guest requests into 5,356 tasks inside Staycity's operational systems, while guests rated the AI's replies almost as highly as human replies.

05 — What's next · The roadmap

From answering guests to reaching them — and picking up the phone.

June's results are a baseline, not a ceiling. Two moves are already underway that take D3x from responding across every channel to proactively engaging guests and covering the last unautomated channel — voice.

NowReactive → proactive

WhatsApp outbound messaging

Moving from reactive to proactive. D3x will initiate WhatsApp conversations — pre-arrival prompts, in-stay check-ins, upsell and service moments — turning the group's most-used channel into a two-way relationship rather than a support inbox. Intent captured earlier, before a guest even has to ask.

Target Aug 2026Full-channel coverage

Phone AI — live across every location

Voice is the one channel still tying up on-property staff. By August 2026, AI phone handling rolls out across all Staycity and Wilde locations — resolving calls end-to-end in the guest's language, around the clock, folded into the same layer that already runs chat, WhatsApp, email and OTA.

Every channel. Every guest. One layer that resolves. Chat, WhatsApp, email, OTA — and soon voice, inbound and outbound. As Staycity opens 20 more properties by 2030, D3x scales the guest experience alongside it, without scaling the cost of delivering it.

The takeaway · Resolves, not routes

The measure isn't messages sent. It's work that gets done.

In one month, across 40 European properties, D3x resolved the majority of Staycity's guest conversations end-to-end, executed over five thousand operational tasks, and earned guest satisfaction on par with the human team — in 14 languages, around the clock. That's the difference between a chatbot that answers and an orchestration layer that resolves.
