Quality data that you can trust

Our approach to sampling gives you the reliable answers you need, from the people you need to speak to.

“I’ve seen a really good consistency in the results which tells me that the sample is of a high quality — it’s got that integrity within the data.”

Grant Warnock, Head of Business Intelligence at Nutmeg

We call it a mixed-methodology approach

Every survey is answered by multiple high quality sample sources. 
This means you get: 

data quality

Quality data, with three layers of checks 

Attest has three layers of quality control built into our mixed-methodology approach – both human and machine-learning-led – for consistently trustworthy data.

diverse audience

Access to the consumers that matter to you

Access to 110 million people in 49 countries means you can reach the niches you need within our diverse audience. Layer demographic targeting and qualifying questions on top. 

broader demographic

Results delivered at the speed you need

Multiple sample sources jump straight into filling your survey, so results come in 3x faster than using a single panel.

Machine learning

No nonsense answers

We have an entire data science team tasked with making the most of your responses. Every survey goes through three layers of quality checks.

A fine-tuned mix of automatic, machine-learning-led algorithms that understand respondent behaviour, and a final human intervention to make sure everything looks right. Responses that don’t pass our checks are automatically removed and replaced, so you only see the best quality data in your results.

Three types of controls

Our quality controls fall into three categories

3 layers of checks

Impossible checks

Background data and/or answers that cannot be real or valid, including impossible demographic combinations and speeding.


Improbable checks

Combinations of background data and/or answers which lead us to reasonably mistrust the responses enough to remove them, including overclaiming behaviours and non-answer thresholds.

Faster than average

Behavioural checks

Continuous monitoring of all answers provided, including the automatic removal of gibberish and irrelevant open text answers.

100s of providers worldwide

Our surveys are sent to 100s of sample providers around the world, and in order to deliver the best possible quality data for our clients we put all of them through a quarterly quality measurement program. Any provider found to miss our agreed quality levels is removed from the provider pool until they have addressed the concerns highlighted.

Demographic filters
Multiple panel sources

Don’t waste any more time

Insights delivered at speed are crucial for spotting trends in real-time, reacting quickly and staying relevant in the market. With our mixed-methodology approach, surveys fill 3x faster than using a single panel, meaning the average Attest survey takes less than 2 days to fill. 

The proof

We put our in-house team of data scientists onto the task of answering our customers’ key questions and compiling the results in one place.
