TECH
The Technology

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.

FlowVue

Visual AI Sync

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

Phone calls convert at 50%. Hotel websites convert at 2.2%. The difference is the conversation. FlowVue bridges both: while your guest is on the phone, their screen comes alive with photos, rates, and availability. Voice and visuals, synchronized in real time.

  • Guest's phone shows rooms and photos the moment they're mentioned
  • Works simultaneously with the voice call. No app, no link, no friction.
  • Web and mobile: the visual experience adapts to the guest's device
  • Hotel staff sees a live replay of exactly what the guest saw
  • No competitor in hotel AI does phone-to-visual simultaneous sync

FlowPilot

Real-Time Sales Intelligence

Live intelligence that steers
every call to a close.

FlowPilot watches every conversation in real time. The moment a call drifts, a price objection surfaces, or the guest hesitates, FlowPilot fires a targeted tactic, invisibly, mid-sentence.

  • Monitors every call millisecond-by-millisecond for drift signals
  • Fires proven tactics: Scarcity, Mirroring, Accusation Audit, Social Proof
  • Supervisor Whisper: inject context silently. Guest never hears it.
  • Recovery rate tracked per tactic, per agent, per property
  • Text channels: FlowPilot reviews drafts before they send

FlowSense

Guest Signal Extraction

The hotel that knows
what you want before you ask.

Every word a guest speaks is a signal. FlowSense reads between the lines of every call, extracting occasion, emotional state, and budget sensitivity, then acts on those signals before the guest ever checks in.

  • Signal extraction on every call: occasion, emotion, planning style, food preference, budget sensitivity
  • Anticipation engine fires actions: pre-arrival texts, staff prep notes, mid-stay nudges, extension offers
  • Cohort intelligence: as guest volume grows, FlowSense learns what works for guests like yours
  • Network effect: insights from every property benefit every other property
  • Auto-fire above 0.85 confidence. Staff review below that threshold.

FlowDojo

Adversarial Testing Platform

2,500 adversarial scenarios.
Before your first real guest.

Most hotel AI is tested by the team that built it. FlowDojo is an adversarial testing platform that runs thousands of simulated phone calls against your deployment, scoring every interaction against the Forbes Five-Star Service rubric. It finds the gaps humans miss.

  • Ralph Loop: automated gap detection across knowledge, tone, upsell timing, recovery, and policy adherence
  • 2,500+ scenario library covering edge cases, multi-language callers, difficult guests, and complex multi-booking requests
  • Forbes Five-Star rubric scoring: every call rated on the same standard the industry's best hotels are measured by
  • Continuous regression: every deployment update triggers a fresh test sweep automatically
  • Gap reports surface the specific training data or policy updates needed to close each weakness

The Stack

Under the Hood

Purpose-built,
not patched together.

No existing managed voice platform gave us the control we needed to build FlowVue, FlowPilot, FlowSense, and FlowDojo. So we built our own pipeline from the transport layer up. Elixir on the BEAM virtual machine. The same runtime that powers WhatsApp and Discord.

  • Millions of lightweight processes, each managing one conversation, each isolated, each fault-tolerant
  • LiveKit for real-time WebRTC transport. Deepgram, Cartesia, and OpenAI composed into our own voice pipeline
  • Every layer replaceable. No vendor lock-in on any single component
  • Global edge deployment via Fly.io. Sub-300ms latency worldwide
