Our Story

Tunk started inside the speech-to-text industry, where accurate transcription stayed locked behind enterprise pricing and English-first models. We built our own engine to change that — and it grew into a platform that talks back.

01
Speech-to-text roots
We built our own engine to make accurate transcription affordable and multilingual — for every team, not just enterprises.
02
Going real-time
Streaming speech-to-text brought that accuracy to live conversations: captions, agent assist, and voice interfaces.
03Today
Voice AI agents
The same engine now powers AI agents that hold full business conversations — answering, understanding, and resolving calls on their own.

What We Build

One voice stack — from live speech to full conversations.

How We Work

The principles behind everything we ship.

Human at the core

AI that serves people — transparent, fair, and accountable. Every product we ship keeps a human in the loop.

Always learning

Our models improve every day. So do we. Standing still isn't an option in voice AI — and we wouldn't want it to be.

Built for everyone

50+ languages, every accent. Voice AI shouldn't have a default user — and ours doesn't.

Ship the future

We build for where voice is going, not where it's been — one bold idea, one fearless step at a time.

Sustainable ambition

Big goals, no burnout. We design a culture where well-being and ambition coexist — the journey matters as much as the destination.
