Majordomo system for cruise lines

See the decision behind every recommendation.

sealevel.suite turns onboard moments into attributed revenue, and shows you exactly why each call was made. Built for the people who run the ship, not the dashboard.

How it works

Three onboard moments, one closed loop.

AIfred reads the moment, makes the call, and proves the result. The same engine runs across the whole voyage.

It sees what your systems miss.

Reads context and guest signals your existing systems cannot see, from booking and history to where each guest is in the voyage right now.

Booking, history, and stated preferences, unified
Live onboard context, not yesterday’s report

Meet sealevel.AIfred

The onboard majordomo at the centre of the sealevel.suite (s³). AIfred senses each guest through Sense, runs onboard on Mate, and works one loop: read the guest, make the call, turn it into onboard revenue.

senses sealevel.Sense

The sensing layer. Reads the cabin and the guest in real time, the signals a booking system never sees.

decides sealevel.AIfred

The majordomo brain. Anticipates what each guest needs, makes the timed call to the floor, and ties every action back to onboard revenue.

runs onboard sealevel.Mate

The edge unit. Runs AIfred in the cabin, installs in minutes, and keeps the data on the ship.

Built in Kiel.

Trust and control

Built to pass a procurement review.

Data stays at sea level

Guest data is processed within your environment and your data-residency rules. We hold nothing we do not need.

Your data, with help to read it

Through the pilot you keep full access to the data you need, and we sit with your team to turn it into clear insight and reporting.

Auditable by design

Each recommendation keeps its token and trail, so any call can be reconstructed and defended later.

Pilot approach

We would rather show you than tell you.

Every relationship starts with a pilot on one sailing, so you can see what AIfred actually does with your guests and your revenue before you commit anything.

01

Scope

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

02

Connect

The suite reads your booking and onboard systems in a read-only pilot. No rip and replace.

03

Run

Recommendations reach the floor for one voyage. Every call carries its trail from day one.

04

Review

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

Team

Two founders, in Kiel.

sealevel is Lasse and Julian. Lasse invented the technology and leads the product; Julian runs the business and finance.
