VOICE · TRADES

The phone,
handled. On site.

Lina answers on your number, books into your real calendar and flags anything urgent straight to you. Built in Germany, hosted in Germany. This page is where you hear her do it.

The uncomfortable math

Every missed call has a price. Here it is.

The front desk that never misses a call starts by counting the calls you are already missing.

Your quiet quarterly bill
Missed calls per quarter60
Avg. value per job× €450
Loss per quarter€27,000
Loss per year€108,000
2-person operation, conservative. €450 is a small job, many run well above that.

of calls come in while you're on a ladder, under a sink, in the noise. Exactly when you cannot get to the phone.

30 sec

is how long a caller waits before hanging up and dialing the next number in the list. The job is gone before the second ring.

On the line

Answers like a dispatcher, not like a bot.

Jobsite, van, roof, basement. Lina picks up on your number in about a second, checks the live calendar, holds the slot and writes the job back. No callback loop, no voicemail, no announcement menu.

She is not a recording playing four canned sentences. She understands what the caller needs and answers in real time, differently on every call. She states that she is an AI assistant at the start, then she does the work.

What she handles. What she never touches.

A voice agent is only as trustworthy as its limits. Lina's are explicit, and they are enforced in code, not in a prompt.

She handles
Every call, around the clock, answered in about a second
Books, moves and cancels jobs in your live calendar
Opening hours, callout fees and service area, straight from your knowledge base
Callback requests and job details, taken down structured, not scribbled on a pad
Written confirmations, plus a searchable transcript of every call
She never does
Guess. Below 0.75 confidence she stops and hands off to your team
Invent prices or availability. If she does not know, she says so
Quote a job she cannot see. No estimates without your sign-off
Share one caller's details with another
Sit on a genuine emergency. Gas leak, burst pipe, no power, and it is flagged for an immediate callback to you, not buried in a queue
Hear it

Do not take our word for it. Press play.

A real clip of Lina's greeting, in German, because that is who she is built for.

01
Greeting and bookingGerman demo call

A caller needs a job booked. Lina greets, finds a free slot and confirms it into the calendar.

Safeguards

She knows where her job ends.

No quotes she is not briefed for. No promises on parts or timing she cannot see. The costly receptionist is the one that guesses, so Lina is built not to.

And everything is on the record. Every call ends as a timestamped transcript with a confidence score on every turn, so you can see exactly what was said and why she handed off.

She names herself.Every call opens with Lina identifying as the business's AI assistant, as Art. 50 EU AI Act requires.
She measures her own certainty.Every turn carries a confidence score. Below 0.75 she stops and hands off instead of guessing.
Warm transfer to your team.The moment a request leaves her scope, a human takes the call. Nobody argues with a bot.
Genuinely urgent jobs skip the queue.Gas leak, burst pipe, no power, and it is flagged straight to your on-call number for an immediate callback. No detour.

Your data

Self-hosted. In Germany.

Lina runs on our own servers, not on a rented US platform. Caller data does not leave the country, is never used for training and is retained under GDPR rules you control.

Hetzner Falkenstein

Hosted on our own hardware in a German data centre.

Signed AVV, Art. 28 GDPR

Part of the contract, ready for your data protection officer.

Registered with the BNetzA

Compliant with German telecoms registration rules.

No US routing

Caller data never crosses the border to a US platform.

No training on caller data

Nothing a caller says is ever used to train a model.

Art. 50 EU AI Act disclosure

Lina names herself as an AI on every single call.

The data processing agreement is part of the contract, ready for your data protection officer on day one. You keep your own API keys, we never see your data.

Common questions. Real answers.

Q01Who trains Lina on our business?

We do, in seven business days. You send your website, price list and the questions your callers actually ask. We build the knowledge base, test against your real scenarios, go live.

Q02How does GDPR work with caller data?

Hosting is exclusively in Germany, at Hetzner Falkenstein. The data processing agreement (AVV, Art. 28 GDPR) is part of the contract. You keep your own API keys, we never see your data, and nothing is ever used for training.

Q03What happens with a genuinely urgent job on the line?

Lina stops the normal flow and flags it for an immediate callback by the rules you define: your on-call number, a shared mobile, whatever fits how your business runs. She never quotes or dispatches a job herself, she just makes sure it reaches you fast.

Q04Which software can be connected?

Google Calendar and Outlook connect natively, plus anything that offers a calendar export or an API. If your job or order-management software is not listed, ask. We build the integration.

Q05Do callers hear that they are talking to an AI?

Yes, always. Lina identifies as an AI assistant at the start of every call, as Art. 50 EU AI Act requires. Callers take it well, because the alternative is that nobody picks up.

Q06What if she cannot answer a question?

She hands off to a human. Every turn carries a confidence score, and below 0.75 she stops and escalates instead of guessing. Every handoff is documented in the call log with the reason.

Q07What if it does not work for us?

Two guarantees. Live in seven business days from the signed brief, or the setup is free. And if Lina answers fewer than 85% of your after-hours calls in the first 60 days and we cannot fix it within 30 days, you get the setup and every monthly fee back.
