The phone rang. Nobody picked up. The customer called the next firm.
Threll answers in Norwegian around the clock – when your hands are full at 11.30, and when nobody is in the office at 21.40. It judges urgency, takes down the details and alerts whoever is on call. You set it up yourself in the console in an afternoon – with help from us if you want it.

The call you don't know you lost
Most firms in this trade know how many jobs they won. Almost none know how many enquiries never became a conversation. The call that came in while your hands were full – in the middle of the day or late in the evening – exists in no system. It exists only with the customer, who called the next firm on the list and got an answer there.
Voicemail takes it
Few leave a message when it's urgent. Most call the next number on the list.
The on-call phone takes everything
The same person is woken for a burst pipe and a price question alike. The rotation wears down, and response gets worse over time.
The answering service takes a message
You pay per call for a summary. The customer still doesn't know whether anyone is coming.
None of the three answers the question the customer is actually asking: is anyone coming?
Run the numbers with your own figures
Three numbers is all it takes. How many calls go unanswered in a month – whether you're mid-job, mid-treatment or mid-driving-lesson, or it's evening and weekend – how many of them would have become a job, and what an average job is worth.
288,000 kr a year – straight into your competitor's pocket
You're losing roughly 24,000 kr a month across 4 jobs. Threll costs 699 kr a month – the subscription pays for itself the second the agent saves the year's very first patient, pupil or job.
We don't know your numbers. You probably don't either – and that is the whole point. The trial week gives you the actual count, whether or not you choose us afterwards.
Live in one afternoon
Five steps you do yourself in the console. You keep your number, your operator and your setup, and need no integration. If you get stuck, we help for free.
Full control of every call
Every call with summary, outcome and recording. You run it all yourself – see what your threll said, and close the gaps as you read.
What the agent actually does
Answers in real Norwegian – and 70 more languages
Natural Norwegian speech that handles dialect and interruptions. If the customer speaks English, Polish or Lithuanian, the agent switches mid-call – and back again.
Books in the calendar
Non-urgent jobs go straight into the calendar, with an SMS confirmation to the customer.
Wanted to move the site visit from Friday. Rebooked to Tuesday 14:00. Asked for the same plumber.
Transcript, summary and sentiment
The whole call in writing, a five-line summary, and a signal on whether the customer was frustrated.
Judges urgency by your rules
You define what counts as urgent. A water leak wakes the on-call engineer. A price enquiry does not.
Calls out as well
Confirmations, follow-ups on quotes and reminders about booked site visits. Same platform, same voice.
Takes down what you need to roll out
Name, phone, address, what happened, how long it has been going on, who has a key. Fixed fields, the same every time.
Transfers or notifies
A transfer to the on-call engineer when it's urgent, an SMS and email summary when it isn't.
Handles several at once
In a storm, a downpour or a cold snap everyone calls at once. The agent takes them in parallel, with no queue.
Payment and authentication with Vipps
The agent sends a Vipps request during the call – to confirm who the customer is, or to take the call-out fee before anyone rolls out.
This is how it sounds – midday and late evening
Two real calls from a standard setup. Hear them – or read them, if you're in the car with someone else.
Frisk Fysioterapi, you're speaking with an AI assistant. How can I help?
Hi, I've got lower back pain and I'm wondering whether you have anything free this week.
We'll sort that out. Have you been to us before, or is this your first time?
First time.
Then I'll set aside a double slot for a first assessment. Thursday at 13, or Friday at 9?
Thursday suits best.
Thursday at 13 with Marit. Can I use the number you're calling from for the SMS confirmation?
Yes, that's fine.
That's booked. You'll get a confirmation now and a reminder the day before. Do come ten minutes early so you have time for the form.

Built for the firms that lose money on an unanswered call
Plumbing and HVACThe water damage grows by the hour. Whoever answers first gets the job.
ElectricianPower cuts and overheating don't wait until Monday.
LocksmithA locked-out customer calls once, not twice.
GlazierA window smashed in a break-in happens at night, never in office hours.
Roofing and water damageIn a downpour, twenty customers call in ten minutes.
Drains and jettingA blocked main is an emergency for an entire building.
Pest controlThe customer is panicking and calls down the list until someone answers.
Veterinary and dental on-callWhoever answers first gets the patient. Triage is half the job.
Caretaking and property managementLift breakdowns and leaks in the building come outside working hours.
Physiotherapy and clinicsThe therapist has their hands on a patient. The phone rings anyway.
Driving schoolsThe instructor is in the car with a pupil. The next pupil is calling now.
Garages and tyresUnder a raised car you hear nothing. Tyre season rings all day long.
The alternatives, honestly laid out
| Option | Customer gets an answer | Urgency judged | On-call is shielded | You see statistics | Cost |
|---|---|---|---|---|---|
| Nothing / voicemail | No | No | Yes | No | 0 kr, but an invisible loss |
| On-call phone on rotation | Yes | Yes | No | No | On-call pay + burnout |
| Human answering service | Partly – they take a message | Rarely | Yes | Limited | Paid per call |
| Permanent receptionist | Yes, in office hours | Yes | Yes | No | Far beyond the volume you need |
| Threll | Yes, around the clock | Yes, by your rules | Yes | Yes, every call | Fixed monthly price |
We don't take over the on-call rota. We make sure it is only woken when it's worth it.

Self-serve setup
Create an account, configure the agent and set up forwarding yourself – in an afternoon. If you need help along the way, it costs nothing.
Create accountDo compare
A human answering service typically charges 25–50 NOK per answered call. A lost customer costs you the whole sale.
Run the numbersWhat your customer hears, and what you need to be able to answer
Five questions you will get – from a customer, a board chair or a procurement officer. The answers are the same on every plan.
The agent says it is an AI assistant
It happens in the first sentence. It is a requirement under the EU AI Act – and it is also what makes customers accept it.
Norwegian and European data storage
Call data is processed within the EEA. A data processing agreement is standard, not an add-on.
Telephony on Telenor SIP infrastructure
The same network as the rest of Norwegian business telephony. No detour across the public internet.
You own the data
Export or delete whenever you want. You set the retention period yourself.
On-prem and sovereign hosting exist
For those who must have it. Most firms in this segment don't need it – tell us if you do.
Yes, and they're told straight away – the agent says so itself in the first sentence. Our experience is that people accept it when they actually get help. The alternative they're comparing it with isn't a human; it's voicemail.
You set the rules for what happens in case of doubt. The default is that uncertain cases are treated as urgent and transferred to the on-call engineer. The whole call is transcribed in the dashboard, so you see exactly what was said.
No. Threll is wired in as forwarding on no answer, busy or outside opening hours. You keep your number, your operator and your setup. If you have Mobilt Bedriftsnett or Telia Bedriftsnett, this is a menu option in your admin panel.
You do it yourself: the forwarding takes ten minutes, and writing what the agent should ask about and what counts as urgent typically takes half an hour in the console. If you'd like one of us on a screen share, it costs nothing.
Yes. Norwegian, Swedish and Danish are specially trained, and the agent handles 70 more languages – it switches mid-call if the caller does.
You keep it. Threll becomes the first line: it catches everything, and only passes on what genuinely needs a call-out.
Turn the forwarding off. No lock-in, no notice period on the trial.
Nothing. You create the account yourself, run one week on your own number and have your own numbers afterwards.
