Uses device fingerprinting to verify identity, while flagging inconsistent environments, spoofing attempts, and duplicate patterns.
Quality is the foundation to everything we deliver
Since 2019, PureScore™ has set the industry standard for respondent-level quality scoring. Powered by PureIntelligence™, its AI models analyze billions of data points per hour across behavioral, device, human, and location signals to identify and address fraud throughout the research lifecycle.
We’ve built a multi-source Marketplace designed to reduce sampling bias and support representative data at scale. The result is faster fielding, cleaner insights, and greater confidence in the data behind every decision.

PureScore™ learns and adapts as fraud tactics evolve
OUR AI ADVANTAGE
Respondent-level AI scoring that protects every data point
PureScore™ analyzes billions of data points hourly across behavioral, device, human, and location signals. Low PureScores™ never reach your survey – only verified participants get through.
PureScore™ is powered by PureIntelligence™, a modular system of AI driven checks spanning behavioral, device, human, and location intelligence. These interconnected modules work together to detect risk from multiple angles and create a dynamic view of respondent authenticity.
As fraud evolves, our systems continuously adapt. PureScore™ operates in real time, scoring respondents as they move through the survey experience and blocking risk before it impacts data quality.

Protect your data with PureScore™ 5.0
Evolved through five versions, PureScore™ 5.0 identifies when respondents deploy AI agents to complete surveys, flagging disruptions instantly through continuity tracking.
Fifth Generation Defense
An added layer of in-survey AI detection
As an extension of PureScore™, version 5.0 offers mid-survey monitoring to detect AI-assisted behavior. This additional quality layer gives teams the flexibility to strengthen data protection during the survey experience.
INTEGRATED INTELLIGENCE
A multi-layer system that protects every survey
Marketplace Governance
PureSpectrum operates a multi-sourced marketplace designed to promote quality, diversity, and representation across respondents. Every supplier must meet strict platform standards before entering the ecosystem, including transparency, fraud prevention controls, and consistent respondent performance.
By sourcing respondents across a broad network of partners and continuously monitoring supplier activity, we create a balanced respondent pool that strengthens data reliability and supports the PureScore™ quality framework.
Pre-Survey Screening
Before a respondent ever reaches a live survey, PureScore™ evaluates multiple credibility signals, including device data, location patterns, and behavioral indicators, to assess respondent quality. Participants who receive a low PureScore™ are blocked from entering the platform entirely.
During the prescreener stage, respondents may encounter a dynamic data quality battery that intelligently determines when additional validation is needed within a session. This system is triggered based on respondent behavior and includes three distinct question types designed to assess consistency, intent, and authenticity. Within the open ended component, PureText™ analyzes responses in real time to detect AI generated language, suspicious phrasing, or inconsistencies, ensuring only credible respondents move forward into the survey experience.
In-Survey Monitoring
As respondents progress through a survey, PureScore™ can be extended into the survey experience to evaluate engagement signals, response behavior, and activity patterns in real time. When enabled, this behavioral monitoring identifies inattentive, automated, or suspicious behavior as it happens, helping detect emerging quality risks while the survey is in field.
At the same time, PureText™ can analyze open ended responses for authenticity, relevance, and consistency, adding another layer of protection to help maintain reliable and high quality respondent input.
Post-Survey Review
After survey completion, you receive data you can trust. Quality controls and respondent level scoring have been applied throughout the survey lifecycle to support reliable insights and consistent data integrity across studies.
PureScore™ continues to improve over time by learning from respondent behavior, strengthening its ability to identify and prevent low quality participation in future research.
Additional options such as data cleaning and PureText™ are available for teams that want deeper review.
Quality Expert Support
In many cases, clients never encounter data quality issues due to proactive, embedded safeguards. When potential risks or unusual response patterns do arise, they are escalated for deeper investigation by PureSpectrum’s data quality team.
Led by senior data science leadership with decades of experience in AI, analytics, and machine learning, this team brings deep expertise in behavioral analysis and fraud detection. They review flagged behaviors, response patterns, and supplier activity to take action quickly, removing respondents, blocking traffic sources, or applying safeguards to protect the integrity of the respondent ecosystem.
Why multi-sourcing protects your data
PureSpectrum has 290+ vetted sources spanning 125+ countries. The result: reduced bias, lower operational risk, and reliable delivery to global audiences.
Reduced Bias
Multi-source sampling blends respondents from diverse recruitment channels. This natural variation decreases bias and improves representativeness, producing samples that more closely reflect your target population across behaviors, demographics, and geographies.
Lower Operational Risk
Multi source distribution lowers operational risk by balancing delivery, quality, and feasibility across sources, ensuring studies remain stable even as conditions shift.
Reliable Delivery
With coverage in 125+ countries and access to both consumer and B2B audiences, multisourcing ensures consistent, reliable delivery across markets without compromising quality or speed.
