The technology behind
unreasonable hospitality.

Four proprietary systems, purpose-built for one job: capturing the revenue your hotel is leaving on the table. Not assembled from off-the-shelf APIs. Every layer built in-house.

FlowPilot

Live Re-Steering · Real-time Sales Intelligence

The best closer in hospitality.

Our AI agent gets sharper the longer the calls go, not the other way around.

Most voice agents start strong and fall apart after five or ten minutes. The reason is simple: one agent is trying to do everything at once, hold the conversation, remember the details, follow the rules, look up the room, take the payment. By minute eight, something gives.

A real close takes a small village. So FlowPilot isn't one agent. It's eight, each with a single job: one holds the conversation, one keeps the memory, one watches the goal, one minds the guardrails, one paints the guest's phone or laptop, and so on. Each one stays fresh because each one only has to be good at one thing.

01 Never forgets a detail. One agent listens and remembers, so the rest don't have to. Names, dates, the spa they mentioned in passing, all still there at minute fifty.
02 One voice. A whole team. While the main agent talks, the others listen to the call and step in the moment intervention is needed. The guest hears one calm voice. Behind it, a team works to close the booking.
03 Show, don't just tell. As FlowPilot speaks, the guest's phone or laptop lights up with the room, the price, the upgrade. Voice persuades. Pictures close.

FlowConnect

Protocol Adapter · Where guest AI agents meet your property

Where FlowStay sits in the agentic commerce stack.

Guest agents on top. Your property on the bottom. Four protocol layers connect them. Every request flows down. Memory flows back up so the next agent call already knows the guest.

FlowStay sits between the agent layer Google ships and the property layer your operators run. OTAs were the last middleware. Protocols are the next. We make sure your hotel speaks them, in voice, in visuals, in memory that lasts a decade.

FlowVue

Visual AI Sync

Show, don't tell. While they're still on the phone.

No one else in hotel AI ships this.

Booking phone calls convert at an average of 50%. Hotel websites visits convert at an average of 2.2%. The difference is the conversation.

Each channel has half the answer. The phone has an expert on the line, flexible enough to handle anything thrown at it. The website has visuals, so the guest can see what they're buying. FlowVue gives each one the other half. The phone call gets visuals. The website gets a voice. The close happens with both.

01 Phone or laptop. Either way. No app, no link, no friction. The visual experience adapts to whatever device the guest happens to be on.
02 Upsells the eye can't ignore. While the agent describes the standard room, the suite quietly fades in beside it. The guest sees the upgrade before they have to consider it. ADR lift, without the hard sell.
03 Speaks every language. Shows every guest. The voice switches languages mid-call. The screen follows. A guest in Tokyo sees prices in yen; a guest in Paris sees them in euros. Localized end to end, no translator needed.

FlowCast

Cinema for High-Intent Stays

When the booking deserves
the big screen.

Some stays sell on a phone screen. A ski week, a suite, a once-a-year escape, do not. FlowCast turns the family TV into a private screening room. The agent narrates. The property reveals itself at theater scale, with cinematic transitions and ambient audio choreographed to her voice. The first audio-visual experience travel has ever earned.

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.

FlowSense

Guest Signal Extraction

The hotel that knows what you want before you ask.

We built FlowSense to restore something hotels lost when they got big: the memory of a great hotelier, scaled to every guest.

Boutique hotels used to know every guest by name. Then chains scaled and the memory died. The next call started from zero, the arrival was generic, the warmth was gone.

FlowSense restores it. It listens to every call, extracts what actually matters, and hands the property a memory that lets the team meet every guest like they've known them for years.

01 Remembered guests spend more. Cross-sell stops being a script and becomes a conversation. The agent knows when to bring the better suite, the right table, the spa morning. Revenue lifts because the offer fits the guest.
02 Surprise turns into loyalty. The booking call ends with the agent knowing it's their anniversary, the kids are vegetarian, and they mentioned a sore knee. By arrival, housekeeping has the heating pad on the bed, the kitchen has the menu marked, and a card from the GM is on the desk. Effortless on your side. Magic on theirs.
03 The work of a great hotelier, scaled. A boutique manager knew every guest by name. FlowSense gives that memory to your whole team. Every agent, every shift, every property, same depth of recognition. No handoff loses context.

The Stack

Under the Hood

The brain is ours. The plumbing is best-in-class.

Most hotel AI is a wrapper around an LLM.

We built the parts nobody sells. A proprietary agent harness. A custom realtime voice pipeline, our own, end to end, from the moment audio leaves the guest's phone to the moment our reply leaves the speaker. A long-term memory system. A prompt architecture spanning eight specialized agents. A supervisor that keeps every call alive when something downstream fails.

The supervisor runs on the BEAM, the runtime behind Erlang and Elixir. BEAM was invented for telephone exchanges, then hardened inside payment systems. We use it for what it was always meant to do: never drop the call.

Speech, synthesis, frontier models, edge infra, we buy from the best in the world and keep every piece swappable. The realtime voice transport itself is ours, because nobody else's was tuned for a thirty-minute hospitality call. Our edge is the brain on top and the pipeline underneath.

Built by us The proprietary brain.
  • Realtime voice pipeline Our own transport, turn-taking, barge-in, and call telemetry. Tuned for thirty-minute hospitality calls, not two-minute support tickets.
  • Agent harness Our own runtime around the model. Tool-calling, guardrails, recovery, telemetry.
  • Memory system Long-term guest memory across calls, channels, and years. Powers FlowSense.
  • Prompt architecture Eight specialized agents, each with its own role, voice, and escalation path.
  • Supervisor (actor model) Elixir/BEAM. One isolated process per call. A failure in one never touches another.
Bought from the best Swappable plumbing.
  • Cartesia, Deepgram Voice synthesis and speech-to-text. Multilingual, sub-300ms.
  • Grok, Gemma Frontier reasoning and fast multilingual response. Routed per task, not per vendor.
  • Fly.io Global edge deployment. Calls land near the guest, not near our office.
