Company
SyntoryLabs is a small team in Langenzenn, near Nuremberg. We build AI voice agents that answer the phone for businesses in German and English, and we stay with every agent after it goes live.
Why we exist
A patient wants to move an appointment. A guest asks about a table for tonight. A driver needs a tow after an accident. These calls come in while your team is with a customer, on the other line or already at home.
Voice AI can now hold a natural conversation, in German as well as in English. What most businesses lack is the time to turn that into an agent that knows their services, follows their rules and hands over cleanly when a person is needed.
That is our work. We build the agent around your calls, test it against the situations your team handles every day, and keep improving it once it is live.
How we work with you
There is no platform to learn and no ticket queue. You talk to us directly, from the first call to every change after launch.
We start with your calls
Before we write a single instruction, we look at how your calls really go: who rings, what they want and what has to happen afterwards.
German is not a translation
Every agent speaks German and English from the start. We write and test both languages instead of translating one from the other.
Honest about being an AI
When a caller asks, our agents say clearly that they are an AI assistant. They never pretend to be a person.
A person is always one step away
When a call needs a human, the agent hands it over or arranges a callback, and the notes are already written.
How we work
Five steps, at your pace. We start small, on your real calls, and you approve the agent’s briefing before it takes a single one.
How the pilot works in detailFirst call
We go through the calls you get: which kinds, what callers ask and what should happen next. No preparation needed.
You getA clear list of calls to hand off
Briefing and rules
We write the agent’s briefing from your information and agree handover rules and note fields with you. You approve all of it.
You getA briefing you have approved
Test calls
Your team calls the agent and tries to trip it up. We adjust the briefing until the answers are right.
You getAn agent your team has put to the test
Pilot
The agent takes real calls of the kinds you choose, for example only after hours. We review the results with you and fix what needs fixing.
You getReal calls answered, notes in your inbox
Live, and kept current
You widen the forwarding when you are ready. When your hours, prices or rules change, we update the briefing.

The team
A small team means the people you meet in the first call are the people who build your agent.
