Voice agents thatfinish the job

Book a demo Read the docs

Tyrrex agents answer the call, understand what's actually being asked, and act on it in your systems — refunding the order, moving the appointment, updating the record. Not a phone tree with better diction.

AvaTier-1 support, 24/7

Picks up on the first ring, pulls the live order record, and resolves the request without a queue or a transfer.

One platform

Built once, watched constantly

The same system that lets you ship an agent in an afternoon is the one that tells you, honestly, how it is performing at three in the morning.

Describe the job in plain language

No flowchart, no intent tree. Write what the agent is responsible for, connect the tools it may call, and publish. Changes go live without a redeploy.

Capabilities

Everything a call actually needs

A voice that sounds right is the easy half. The rest is knowing your business, reaching your systems, and behaving when the conversation goes sideways.

Answers grounded in what you actually published

Point it at your help centre, policy docs, or a database view. Tyrrex re-indexes on change and cites the source behind every answer, so a wrong reply is traceable instead of mysterious.

Every answer returns the passage it came from.

Real phone numbers

Bring your own SIP trunk or buy a number in 38 countries. Warm transfer, hold, and DTMF all behave the way callers expect.

Guardrails you configure

Topic limits, refusal behaviour, and PII redaction before anything reaches storage or logs.

Tools that run, not tools that pretend

Give the agent typed functions against your own API. It calls them mid-sentence and keeps talking while the request is in flight.

Handoff that carries context

When a person takes over, they get the transcript, the intent, and what was already tried — not a cold line.

32 languages

Detected from the first utterance, switched mid-call if the caller does.

Interruptible by design

Barge-in stops the agent mid-word, the way a person stops when you talk over them.

Scored, not just stored

Every call is transcribed and graded against your own rubric, so quality is a number you can watch move.

It plugs into the stack you already argue about

Native connectors for the systems most calls end up touching, plus a typed HTTP tool for everything else. No middleware tier to maintain.

Trust

Safety that shows up in the defaults

A voice on a phone line carries obligations a chat widget does not. The conservative choice is the one that ships turned on.

Read the trust centre

The caller always knows

Agents disclose that they are automated on connection, in the caller's language, and hand to a person the moment one is asked for. Disclosure is not a setting you can quietly switch off.

Your data stays where you put it

Choose the region audio and transcripts live in. Nothing trains a shared model, retention is yours to set, and deletion actually deletes rather than tombstoning a row.

Redacted before it lands

Card numbers, health details, and identifiers are stripped in the pipeline — before storage, before logs, and before anything reaches an analytics tool.

Everything we shipped

Put it on a real line and listen

We will stand up an agent on your own docs and a test number, usually inside a week. If it does not hold up on your calls, you will know quickly and cheaply.
