The Challenge

Every enquiry needs the same information, gathered by hand

Before a human can respond meaningfully to a travel enquiry, someone has to extract budget, traveler count, dates and preferences from a free-form message or call - then reply in a tone that matches the brand, whichever person on the team picks it up. None of that scales with enquiry volume, and none of it is captured anywhere structured.

Every enquiry manually triaged before anyone knows if it's worth a human's time

Tone and voice depend on whoever happens to answer

Text and voice enquiries handled through completely different, ad-hoc processes

No structured record of what a lead actually needs until a human writes it down

Our Solution

A multi-agent chat that gathers, scores and hands off - in the brand's voice

We designed a chat system built from purpose-scoped agents rather than one general-purpose bot: a conversational agent that guides the enquiry, an assessment agent that scores and qualifies it against configurable thresholds, and a set of concierge agents that handle the surrounding workflow once a lead is qualified.

Guided assessment, not a form

The conversation itself gathers budget, dates, travelers and preferences, tracking what's still missing turn by turn.

Streamed text and voice

Replies stream token-by-token for a natural feel; voice messages are transcribed and answered in the same flow.

Brand-matched tone by retrieval, not fine-tuning

The agent's voice is anchored by retrieving real past replies that match the situation, curated by the team rather than baked into a model.

Qualification before hand-off

Configurable lead-score and budget thresholds decide which conversations reach a human, and when.

What changed

How enquiry handling changed

Enquiry handling moved from manual, person-dependent triage to a structured, brand-consistent chat that does the qualifying work before a human is needed.

Enquiry channel

Before

Manual email and WhatsApp threads

After

Guided AI chat, text and voice

One conversational surface instead of two disconnected, manual ones.

Tone of voice

Before

Depends on whoever replies

After

Retrieved from curated past correspondence

Consistent brand voice without training a model on it.

Lead qualification

Before

Every enquiry triaged by hand

After

Automatic scoring against configurable thresholds

Humans see qualified leads, not raw inboxes.

Enquiry data

Before

Buried in free-form messages

After

Captured as a structured assessment as the conversation happens

Nothing needs re-typing once a human takes over.

The Outcome

From manual triage to a qualified hand-off in one conversation

The chat system is live and handling enquiries end to end, from first message to qualified hand-off. Client-specific volumes are confidential; figures below are ranges validated against the pre-launch benchmark.
