Five hundred in the sample. Fieldwork stopped at forty, because nobody had time to call the rest.
Threll calls your sample in Norwegian and asks the questions in the same order every time. Respondents can also call in themselves when it suits them. The answers arrive structured and comparable, with the whole call transcribed. You set it up yourself in the console in an afternoon – with help from us if you want it.

The fieldwork that never finished
A sample of five hundred is not five hundred answers. It's five hundred calls that have to be made in the evening, by someone who asks the questions identically every time. That's why telephone surveys cost what they cost – and why most of them end up as a web form instead.
The web form reaches the willing
The people who answer online are the people who most want to answer. That isn't the same thing as your sample.
Interviewers ask differently
Ten temps on an evening shift place tone and probing questions a little differently. The difference ends up in the numbers, not in the methodology note.
The agency charges per interview
The price per completed interview decides how large the sample gets. Which means the budget decides how certain the numbers are.
None of the three answers what you actually need to know: what do the ones we never reached think?
Run the numbers with your own figures
It takes just three numbers. How many interviews you want in a month, what share of them you can't field yourself, and what a completed interview costs at an agency.
You're paying roughly 157,500 kr a month for 350 interviews. Threll Start costs 699 kr.
We don't know your numbers. But sample size is almost always set by the field budget rather than by the method – and that's the whole point. The test week gives you the price of your own fieldwork, whether or not you pick us afterwards.
Live in a single afternoon
Five steps you do yourself in the console. The agent calls out from the list and takes calls in on your number – you choose whether to use both directions or just one. 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
Interviews in real Norwegian – and 70 more languages
Natural Norwegian speech that handles dialect and interruptions. If the respondent speaks English, Polish or Lithuanian, the agent switches mid-call – and the answer lands in the same dataset.
Arranges the interview for when it suits
If now is a bad moment, the agent agrees a time and calls back then. The respondent isn't interviewed in the middle of dinner, and you don't lose the answer.
Switched supplier over price, not quality. Named two competitors unprompted. Would still recommend.
Transcript, summary and sentiment
The whole interview verbatim, a five-line summary, and a signal on how engaged the respondent was. Open answers can be read, not just counted.
Screens against the quota
You define the criteria. If the respondent falls outside the quota, the interview ends politely after the screening questions – without using up your time or theirs.
Calls the whole sample, not a convenience sample
Five hundred or five thousand in the sample costs the same in time: none. The agent works through the list in the evening and retries by your rules.
Captures the answers structured
Closed questions, one-to-five scales, and open answers verbatim. Fixed fields in the same order every time – ready for export, not for tidying up.
Transfers or notifies
If the respondent wants to speak to a person, the agent transfers within opening hours. Otherwise the project lead gets a summary by SMS and email.
Interviews many at once
The whole sample can be called in one evening window. The agent takes them in parallel, so the field period is measured in days rather than weeks.
Incentive paid out with Vipps
The agent sends the incentive by Vipps right after the interview – the respondent has the money before hanging up. No gift-card codes by email three weeks later.
This is how an interview sounds on a Thursday evening
A real call from a standard setup. Listen to it – or read it, if you're in the car with someone else.
Hello, this is an AI assistant calling on behalf of Nordisk Analyse. We're running a survey about electricity suppliers, and it takes about six minutes. Is now a good time?
Yes, that's fine as long as it doesn't take any longer than that.
Thank you. First: have you switched electricity supplier in the last twelve months?
Yes, in February I think it was.
And what was the main reason you switched?
It was the price, really. I got an offer that was quite a bit cheaper, and that was that.
On a scale of one to five, how satisfied are you with the new supplier?
Four. They're fine, but the app is slow.
Noted: four, and that the app is slow. That leaves us three questions.
Need help getting started?
Book a meeting with us and we will help you get going.

Built for the teams that let the budget decide the sample
Research agenciesField cost has been setting your sample size. Now it doesn't.
Membership organisationsA member survey that only lives online only reaches the board.
Local and central governmentResident surveys should represent everyone, not just the digital.
E-commerce and retailWhy they didn't come back isn't recorded in the basket.
Banking and insuranceCustomer surveys in a regulated sector need auditable answers.
Property and lettingsResident surveys rarely reach the people who actually complain.
Health and social carePatient experience is told better out loud than in a form.
Politics and public opinionA poll is worthless if it only reached the people with time to spare.
Brand and productConcept testing needs follow-up questions, not tick boxes.

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 in the first sentence – the agent says so before it says what the survey is about. For an interview that's also a methodological advantage: everyone gets exactly the same wording.
The questions are asked word for word identically to everyone, in the same order, with no interviewer effect. The whole interview is transcribed, so you can audit any call afterwards – which you rarely can with a hired evening team.
A survey is not marketing, so opt-outs from cold calling don't apply. You still need a lawful basis for processing the personal data, and the agent ends the call politely the moment a respondent declines. If the survey also sells something, it is marketing, and then the ordinary rules apply.
Yes. You write the screening questions and the criteria yourself. If a respondent falls outside the quota the interview ends after screening, and the agent carries on down the list until the quota is full.
Answers are stored structured per question and can be exported, with the open answers verbatim alongside the codes. You skip the transcription round between field and analysis.
The agent thanks them and ends the call. The number is marked as a refusal and never dialled again, no matter how many attempts you configured.
No. Outbound calls are placed from your own number, and if you want to take calls in as well, a number is forwarded to it. You keep your number, your operator and your setup.
You do it yourself: uploading the sample takes ten minutes, and entering the questionnaire typically takes half an hour in the console. If you'd like one of us on a screen share, it costs nothing.
Nothing. You create the account yourself, run a week of fieldwork on your own sample, and have your own figures afterwards.
