Company Description

Formerly European National Panels, in  2025 rebranded to National Sample as we are expanding from Europe to Asian market starting with Thailand. The company was established in 2012 through the merger of the online panels of 3 leading market research agencies in the Czech Republic and Slovakia: Nielsen Admosphere, NMS Market Research, and STEM/MARK. Currently we are serving the Czech Republic, Slovakia, Poland, Hungary, Bulgaria, Romania, Ukraine and Thailand. All panels are proprietary, we use own in-house developed sw. We have no bots, no click farms, each panelist has one unique phone number, email, and bank account. All panelists undergo mandatory email and phone verification (SMS) and optional AI facial verification with the use of Real eyes sw to check for gender and age (around 75% of new panelist comply with this requirement). Today, our panels have about 200,000 panelists answering around 3 million questionnaires annually. Discard rate is extremely low (3-5%), response rate extremely high (35-60%) depending on the country. We know a lot about our panelists as we have over 2000 individual data points on each panelist.

1. We put our panellists first

Respondents are treated fairly; every survey participant is rewarded, including quota-fulls and

screen-outs, as long as they pass quality control. Money withdrawal limits are reasonable (approximately € 8 minimum). Panel members can also choose a prize from our gift catalogue or donate to selected charities. Support is always provided by a local team in the local language, with a response time of less than 24 hours. We don't use chatbots; instead, our experienced staff handles each request individually. In addition to rewards for research participation, we engage panellists through contests, newsletters, and social media communication.

2. Unique way of recruitment and verification

You won’t fifind robots or duplicate respondents in our data. In addition to using digital fifingerprints and monitoring device usage, GPS location, we verify the identity of each new panellist by phone via SMS. Those who fail the verification process are not allowed to participate in surveys. Respondents also undergo AI verification of gender and age using a camera. Panel members are recruited through a diverse range of online and offline channels, with approximately 30% of recruitment to date conducted offline. We place special emphasis on reaching groups that are traditionally harder to find online, ensuring the best possible representation of the sample within the market.

3. Transparency and quality bring trust

Panel management and data protection are fully compliant with GDPR, ESOMAR, and SIMAR

(Czech association of Market Research Agencies) standards and guidelines. In 2024, we embraced

responsibility and are fully committed to upholding the so-called Quality Pledge. Panellists are limited to completing a maximum of 3 surveys per week and 45 per year, although the average participation is only 15 completed surveys annually. To ensure high-quality responses, we use a trust score system to monitor participant behaviour (e.g., speeding, straight-lining, etc.). Repeat offenders are permanently removed from the panel. Additionally, we do not use survey routing or river sampling, ensuring the integrity and reliability of our data.

4. Profiling

More than 270 questions and 2,000 individual data points are available for the preliminary targeting of suitable research participants.

5. Technology

All web and mobile panel management software is developed in-house. We utilize our proprietary project management tools, robust incentive management system, and efficient support- ticketing platform. National Sample securely stores all its data within the EU.
