Synthetic Users

JENTIS Synthetic Users is an AI-driven martech solution designed for marketing professionals seeking to activate every website visitor, even those who opt out of tracking. By replacing missing user data with synthetic users generated from the highest-quality first-party signals, JENTIS transforms data blind spots into a real competitive edge and measurable business impact.

This technology uses your actual first-party data to create anonymous, privacy-safe synthetic users, enabling you to activate all your website users across every ad platform. This improves campaign efficiency and can increase your ROAS by up to 25%.

In this article, we explain how JENTIS Synthetic Users work, why it is unique in the market, and how it can help you make better data-driven decisions to boost your marketing results.

The data challenge for marketing strategies

Marketing today faces a critical challenge: shrinking data availability. Ad blockers, browser privacy features, and increasingly strict regulations mean marketers often only have access to a fraction of their website user data. In some regions, consent rates have dropped below 50%, leading to as little as 30% of reliable data for campaign optimization.

This loss of data visibility creates uncertainty in tracking customer journeys and impairs the ability to make informed marketing decisions.

More importantly, it directly affects the algorithms powering your ad platforms. These algorithms rely heavily on accurate, comprehensive conversion data to optimize bidding, targeting, and budget allocation. With incomplete or missing user data, the algorithms receive limited signals, reducing their effectiveness and resulting in higher costs, lower conversion rates, and ultimately, diminished campaign performance.

How can marketers sustain growth and maximize ROI when the customer journey is obscured and ad tools struggle with incomplete data?

How JENTIS solves this problem

JENTIS Server-Side Tracking replaces third-party cookies with first-party cookies, bypassing common tracking blockers and adblockers. Essential Mode enables compliant data capture from non-consenting users for analytics.

Now, JENTIS Synthetic Users take this further by compliantly bridging data gaps with AI-generated synthetic data. This technology lets you share unique, privacy-safe identifiers — like GCLID and FBCLID — in ad platforms without exposing individual users’ personal information.

What are Synthetic Users?

Developed in collaboration with top data protection lawyers, mathematicians, and global measurement experts, Synthetic Users use your real first-party data to train AI models that identify user segments with similar behavioral patterns.

When users deny consent, the AI assigns them to these segments and models their behavior based on consenting users' data, generating synthetic users that act as proxies for the missing data.

Click IDs from each segment are pooled anonymously. Upon conversion, a random ID from the segment is selected and sent to the advertising tool — ensuring privacy compliance without sacrificing data richness.

Why choose Synthetic Users?

  • No Black Boxes, Only Real Data: Unlike extrapolations or modeled guesses, Synthetic Users are generated from your actual first-party data and fully integrated into your ad stack.

  • Boost Campaign Performance: By activating previously invisible users, you can increase your campaign ROAS by up to 25%, lower your cost-per-conversion, and improve conversion rates.

  • Expand Audience Reach: Access previously unreachable audience segments to improve targeting and bidding.

  • Privacy First: The solution is GDPR-compliant, does not rely on third-party cookies, and avoids dark patterns.

  • Seamless Integration: Works with all major marketing platforms like Google Ads, Meta, TikTok, and more, without extra server maintenance or high costs.
