For cruise lines

Every guest is having a different day.

Yet most onboard offers still reach every guest the same way: one message, one send time, one screen for all. So the right offer rarely meets the right guest at the right time.

The problem

Same ship. Same morning. Three very different guests.

Look at any morning on board through your guests’ eyes. Each of them wants something different from the day. All of them get the same message.

One message for everyone is not personal. For most guests, it is noise.

And noise has a cost that never shows up in a campaign report.

What it costs you

Noise costs more than attention.

Onboard is where a voyage earns a large part of its revenue. Every message that misses makes the next one easier to ignore.

01

Guests tune out.

The more everyone receives, the less anyone reads. The offer that would have fit is lost among the ones that never could.

02

Capacity sails empty.

A spa slot at 10:30, a table at 19:30, a seat on tomorrow’s excursion. Once the moment has passed, that revenue does not come back.

03

Nobody knows why it worked.

When a guest does say yes, no system can tell you why. So the next sailing starts guessing all over again.

The best service never hands you a brochure.

It reads the moment, suggests one thing, and steps back.

A better kind of service

Think of the best concierge you have ever met.

They notice how you are, remember what you like, and suggest one thing at the right moment. Then they step back.

Thousands of cabins.

Thousands of different days.

Let’s follow one.

One sea day, on board

Her day, the way it should feel.

The same guest from Cabin 7115. This time one line appears when something fits, and nothing appears when it does not.

A calm spa treatment room with folded towels and a wide window over a glittering sea

A bad night. A sea day. One quiet suggestion.

She did not sleep well. The morning is open, and the spa has a place at 10:30. One line appears on the screen she already uses. No list. No campaign.

Good morning. A quiet start to your sea day? Your place in the spa is free at 10:30.

Nothing fit, so nothing was sent.

Four and a half hours of sea day, and her screen stays quiet. No happy hour, no flash sale. Relevance comes before volume.

Fully booked is not the end of the afternoon.

Her usual treatment is full today. Instead of a dead end, one alternative that suits how she feels right now, at a time that is actually free.

Your usual massage is fully booked today. Two quiet loungers in the thermal suite are free at 16:30.

An evening worth remembering.

It is the last evening at sea and nothing is booked yet. Two seats at the chef’s table are still free. One invitation, early enough to say yes.

Two seats at the chef’s table are free tonight at 19:30, your last evening at sea. Shall we hold them for you?

What changes

One right moment pays off three times.

The same decision improves the guest’s day, makes service easier for your teams, and earns more from the capacity you already have.

For your guests

Fewer messages, better moments. A cruise that feels as if it was planned around them.

For your onboard teams

Know what to offer, to whom and why, with the reasoning attached. No dashboard to read mid-service.

For your revenue

Capacity you already have, filled by guests who want it. Every booking tied back to the recommendation that earned it.

Meet AIfred, the majordomo on board.

AIfred brings together who a guest is, how they are right now and what is actually available on board. It picks one recommendation, places it on a screen the guest already uses, and keeps the reasons with it.

01

Understands the moment

Booking, history and preferences, plus how the guest is right now: sleep, recovery, presence in the cabin.

02

Decides on one offer

One recommendation, not a list to sift. The right channel, timed to the moment. And nothing at all when nothing fits.

03

Proves what it earned

Every booking tied back to the call that earned it, so the value of a sailing is measured, not estimated.

Pilot approach

Prove it on one sailing.

One voyage, one metric agreed before anything ships, and a review built on attributed revenue. Then you decide.

    Scope

    Pick one sailing and the moments that matter. We agree on the metric before anything ships.

  2. 02

    Connect

    Read-only access to your booking and onboard systems. Pilots can start with guests’ compatible wearables, so no cabin hardware is needed on day one.

  3. 03

    Run

    Recommendations reach guests and onboard teams for one voyage. Every call carries its trail from day one.

  4. 04

    Review

    We sit down with attributed revenue, not a demo. You decide whether to expand to the fleet.
