Why Threll

  • Resolves it in the call

    The most common enquiries are finished in the conversation, with no queue.

  • Answers straight away

    The threll picks up on the first attempt, however many people call at once.

  • 24/7 availability

    Never closed, never sick. Always available.

  • The same quality every time

    The same tone and the same routine at 3am as at 10am.

How it works

An AI receptionist that knows your customer

The threll receives the call, looks up the customer in real time, understands what they need — and handles the case. Everything from answering questions to performing tasks in your business systems. And when a human is needed, the threll ensures a seamless transfer with full context.

  • Step 1

    Identification

    When the customer calls, we immediately look up the number against CRM or caller ID services to know who we are speaking with — and what we have talked about before.

  • Step 2

    Intent understanding

    The threll listens, understands, and classifies the customer’s needs in real time. No menus, no "press 1 for...".

  • Step 3

    Triage

    Based on intent and context, the call is handled correctly — either to automatic resolution, lookup in business systems, or the right person.

  • Step 4

    Action

    The threll answers questions from knowledge bases, performs tasks in third-party systems, books appointments, updates cases — all in real time.

  • Step 5

    Escalation (when needed)

    When the case requires a human, the call is transferred seamlessly with full context — so the customer never has to repeat themselves.
