FLOWSTAY FOR CRUISE LINES

Runs on the ship. Not on the cloud.

Voice agents that run on the ship, so they don't strain your satellite link, or your guests'.

From the team that's installed shipboard servers on some of the world's largest cruise ships.

TWO PHASES · ONE ROADMAP

Pre-cruise today. Onboard next.

Cruise procurement cycles are long. Here's exactly what you can buy now, and what's coming, so your team can plan the full deployment, not guess at it.

LIVE NOW · PILOT-READY

PHASE 1

The pre-cruise booking line.

A shoreside reservations agent that answers your central booking number. New cabin bookings, modifications, cancellations, pre-cruise upsells. No ship install, no satellite touch. Runs entirely in our cloud, forwarded from your existing PBX. 30-day free pilot. Live in two weeks.

Cabin booking & modification
Pre-cruise dining, spa, shore-excursion upsell
Loyalty-tier recognition & preference recall
Group & charter inquiries

IN BUILD · FLEET ROLLOUT

PHASE 2

The onboard agent.

The same agent, running on a redundant server pair in your ship's equipment room. Calls land on the ship and never leave. Sub-300ms voice loop, indifferent to the satellite link. Survives outages. Eliminates satellite cost on every guest call.

On-prem inference, voice loop closes on the ship
Guest-facing concierge across cabin phone, app, kiosk
Data sovereignty: nothing leaves the ship without sign-off
Fleet rollout pattern: pilot ship → class rollout → fleet

WHY FIRST-GEN VOICE AGENTS CAN'T SAIL

They live in the cloud. The ship doesn't.

Vapi. Retell. Bland. ElevenLabs Conversational. Every one of them assumes a fat, always-on internet pipe sitting between the caller and a US datacenter. On a cruise ship that pipe is satellite, it's shared with thousands of guests, and it's the most contested resource on board. Putting voice agents on top of it isn't an architecture choice. It's a tax.

Every call eats your satellite link.

Cloud voice agents push every word, every model token, every tool call out over your satellite connection. The same pipe your guests are streaming on, the same pipe your POS, PMS, and bridge systems share. FlowStay's inference runs onboard, so the call never leaves the ship.

Latency stacks when the call routes to land.

Satellite round-trips add 500-800ms before the model even starts thinking. Layer a cloud LLM on top and the guest hears dead air every turn. FlowStay's voice loop closes on the ship, sub-300ms end to end, indifferent to the link.

When the link drops, the call dies.

Satellite outages aren't rare, they're scheduled. Weather. Beam handoffs. Capacity caps. A cloud-hosted voice agent dies with the link. FlowStay keeps taking calls through outages, because the brain, the catalog, and the booking state all live onboard.

HOW IT'S WIRED

The voice loop closes on the ship.

The brain, the catalog, the booking state, the voice models, all of it runs in a redundant server pair in your ship's equipment room. Calls land on the ship and never leave. The satellite link only carries the things that can wait: nightly catalog deltas and audit logs back to shore.

WHO BUILT IT

We've put servers on cruise ships before.

Before FlowStay, our team designed, built, and installed on-prem compute on some of the world's largest cruise ships. Racks shipped, networked, commissioned, and kept running at sea. Not a slide. Hardware bolted into a server room above the engine deck.

On-prem voice for a cruise line isn't a research project for us. It's the same playbook, with newer hardware and a smarter brain on top of it.

WHAT THAT LOOKS LIKE ON BOARD

An agent that lives on the ship, and acts like it.

When the brain runs onboard, the call gets shorter, smarter, and never depends on the link. Guest memory is already there. Catalog is already there. Booking state is already there. The agent picks up the phone the way a senior reservations specialist would on their tenth year, with everything they need already in front of them.

Guest memory loads on pickup.

Past sailings, cabin preferences, dining tier, beverage package, loyalty status, shore-excursion history. FlowStay pulls the full guest profile before "hello" and keeps it warm for the entire call, no re-asking, no re-routing.

Voice and visuals, coordinated.

Deck plans, cabin photos, excursion previews, dining menus, beverage tiers, sent to the guest's phone in real time as the agent speaks. The call does what voice alone can't: let the guest see what they're choosing.

Fleet-scale catalog, no collapse.

Multiple ships. Twenty cabin categories per ship. Hundreds of excursions per itinerary. Dynamic dining, beverage, spa, and Wi-Fi inventory. FlowStay holds the whole catalog in working context and reasons across it without losing thread, even at minute forty.

AGENTIC COMMERCE · ONBOARD

Agentic booking,
even at sea.

When the protocol calls, the brain answers locally. Spark and ChatGPT can plan an entire sailing from shore, FlowStay responds with live cabins, dining, excursions, and spa, and the agent on the ship handles the conversion the same way it would for a guest calling the bridge phone in cabin 7042. No satellite link required to think.

SHORESIDE AGENTS

Spark, ChatGPT, Gemini reach your line directly through UCP and MCP. Your brand is the destination, not a row on an OTA.

SHIPSIDE BRAIN

Same agent runtime on the ship handles in-cabin requests offline. Protocol intent in, full sailing booked out.

THE PHONE

The phone call
that talks AND shows.

A guest asks about the balcony stateroom. It appears on their screen, rendered, as the agent describes it. The deck plan. The specialty restaurant. The shore excursion they'll book for Tortola. Each on cue, no app, no download. Visual pitches close at 2–3× voice alone.

THE WEBSITE

Your cruise-line website
just found its voice.

Your website becomes part of the call. The guest asks about cabin categories, dining, shore excursions, beverage packages, the spa. Each renders on screen as the agent speaks, choreographed to what they're hearing. Closer to a private at-sea preview than a webpage. Direct booking just got compelling.

CINEMA FOR THE CALL

When the sailing deserves
the big screen.

Some sailings sell on a phone screen. A seven-night Caribbean cabin, a transatlantic suite, an Alaska family booking, do not. We turn the family TV into a private screening room. The agent narrates. The ship reveals itself at theater scale: drone reveals of the lido deck, the suite category in 4K, the shore excursion in Tortola, all choreographed to her voice.

Call 05:00

Cart $0

01 The cast happens mid-call. A simple "Shall I send this to your TV?" and the property fills the living room. No app, no link, no setup. Works on whatever they're already watching.

02 Cinematic, not a slideshow. 4K imagery, drone reveals, ambient audio tuned to the property. The TV becomes a theater. The booking call becomes an event.

03 Synced to the voice. The agent says "private hot tub." The TV cuts to that exact frame. Every word, the screen answers.

THE TEAM · LIVE

The whole ship, on one phone line.

Nine specialists, one shared memory. Cabins. Dining. Shore. Beverage. Spa. Photo. Wi-Fi. Transfers. Loyalty. When you're the easiest call to make, you're the only call they make. Onboard spend stays onboard.
