Infillion, the agent-native media execution platform, has announced a strategic partnership with Yobi, the behavioural AI company.

The collaboration combines Infillion’s composable advertising infrastructure with Yobi’s advanced machine learning capabilities to deliver walled garden-level campaign performance on the open web-effectively bringing Google Performance Max-style optimisation to independent advertisers and agencies.

The partnership addresses a critical industry challenge: AI models are only as effective as their underlying data, yet accessing differentiated consumer signals at scale has never been more difficult. 

Through this collaboration, Infillion clients will gain access to Yobi’s privacy-first optimisation services, including advanced audience targeting, bid optimisation, and identity resolution capabilities supported by a large consented consumer dataset.

“This partnership is fundamentally about levelling the playing field-bringing the performance capabilities of walled gardens to the open web,” said Rob Emrich, Founder and Executive Chair at Infillion.

“Yobi’s privacy-preserving approach to behavioural data solves the signal scarcity problem that has plagued the industry since third-party cookie deprecation, while our composable platform ensures these AI capabilities can be deployed with speed and precision.”

Democratising AI/ML Through Privacy-First Innovation

Yobi, which has compiled a large consented consumer database in the US, democratises behavioural intelligence to drive enterprise growth and advance the study of human decision-making. 

Its differentiated approach creates privacy-preserving representations of behaviour from predictive signals, unlocking the same customer preference insights that big technology companies enjoy while making AI/ML capabilities accessible for enterprises of all sizes.

For advertisers and media buyers, this translates into sharper audience targeting, faster optimisation, and stronger ROAS, without relying on cookies or walled-garden data. 

As a steward for behavioural datasets from multiple industries, Yobi uses machine learning technologies to build tools that allow clients to understand current and prospective customer behaviour without handling sensitive, identifiable information.

“As AI transforms advertising, the winners will be the companies that can channel customer data into real performance at scale – without the privacy risks or being beholden to the biggest tech platforms,” said Max Snow, CEO and Co-Founder of Yobi. 

“With Infillion, we’re bringing our behavioural AI directly into media buying and optimisation workflows, helping traders identify higher-intent audiences, adapt faster to live signals, and drive stronger campaign outcomes, using trusted privacy-first signals built for today’s addressability landscape.” 

“Infillion’s open platform makes it possible to activate these models across channels, proving that open ecosystems deliver better performance than closed systems.”

Breaking the Walled Garden Monopoly on AI Performance

With Yobi’s AI embedded in Infillion’s platform, advertisers can use advanced machine-learning models to inform audience targeting and real-time optimisation inside their current media workflows, rather than handing those decisions off to closed, black-box systems. 

The partnership directly addresses advertisers’ frustration with limiting AI optimisation choices like Google’s Performance Max with its lack of transparency and control.

Infillion’s new offering with Yobi allows for Audience Insight Ownership, including segment-level performance across all campaigns, bid-level visibility, budget control & reporting, forecasting based on actual delivery data, and measurement independence.

Key Partnership Benefits:

• Walled Garden Performance, Open Web Control: AI-driven optimisation comparable to Google Performance Max, with full transparency and interoperability.

• Accelerated AI Performance: Yobi’s predictive models, data, and real-time signals dynamically adapt to shifting consumer intent, automatically optimising targeting and bidding to accelerate performance.
• Privacy-Preserving Enrichment: Built on compliance, first-party signals that minimise enterprise risk while maximising performance.
• Operational Efficiency: A unified behavioural training set for enterprise AI reduces data fragmentation and vendor sprawl, accelerating model deployment and activation.
• Enterprise-Grade Scale: Integrated behavioural signals give advertisers unmatched visibility into customers and their intent, as well as what’s actually driving ad performance, at scale.

The partnership becomes effective immediately, with Yobi services being integrated across Infillion’s managed service and self-service campaign offerings throughout 2026. 

Through this collaboration, Yobi will serve as Infillion’s audience and modelling partner, with its behavioural AI as the primary optimisation solution across supported campaigns and its services available to clients across both of Infillion’s business units.
