MarTech Podcast™: Mozilla’s Privacy-Friendly Ad Targeting
Release Date: July 7, 2025
Host: Benjamin Shapiro
Guest: Graham Mudd, SVP of Product at Anonym (acquired by Mozilla)
Introduction
In the July 7, 2025 episode of the MarTech Podcast™, host Benjamin Shapiro engages in an insightful conversation with Graham Mudd, the Senior Vice President of Product at Anonym, a privacy-centric advertising company recently acquired by Mozilla. The episode delves into the evolving landscape of digital advertising, emphasizing the critical balance between effective ad targeting and consumer privacy.
The Challenge of Modern Ad Targeting
Benjamin Shapiro opens the discussion by highlighting pressing statistics from Deloitte's 2024 Connected Consumer Survey:
- 85% of US consumers have taken steps to protect their online privacy.
- 75% feel powerless in safeguarding their personal data.
- 25% believe that both companies and hackers can access their data regardless of their actions.
These figures underscore the growing consumer apprehension towards data privacy and the consequent challenges marketers face as traditional cookie-based tracking becomes obsolete.

"These are not random numbers. These are your customers."

Privacy-Preserving Targeting: A Coexistence Paradigm
Graham Mudd posits that effective ad targeting can indeed coexist with consumer privacy. He emphasizes the importance of leveraging first-party data, which refers to the data collected directly from consumers through interactions such as purchases or sign-ups. By utilizing advanced, privacy-safe machine learning techniques, marketers can identify "lookalike" audiences that mirror their existing customer base without sharing actual customer data with ad platforms.
Key Points:
- First-Party Data Utilization: Focus on data collected directly from customer interactions.
- Privacy-Safe Machine Learning: Employ algorithms that process data within secure environments, ensuring data privacy.
- Lookalike Modeling: Identify and target audiences similar to existing customers without direct data sharing.
Quote:
"We can use it in a way that doesn't require you to share those customers' data with any of the ad platforms you want to work with."
— Graham Mudd [02:31]
Consumer-Friendly Privacy Explained
Shapiro seeks to simplify the concept by comparing traditional tracking to dating dynamics, underscoring the shift from invasive tracking to respectful, privacy-conscious targeting.
Analogy:
Consumers are akin to individuals who, after an initial positive interaction (a "first date"), prefer not to be relentlessly pursued but are open to being introduced to similar, like-minded individuals.
Quote:
"Consumers are basically saying, thanks for the drinks but I don't want a second date."
— Benjamin Shapiro [05:32]
Comparative Analysis: Anonym vs. Google’s Privacy Sandbox
The conversation transitions to how Anonym’s solution stands apart from Google's Privacy Sandbox:
- Privacy Sandbox: Primarily browser-based (focused on Chrome), relying on on-device computations and lacking cross-device capabilities.
- Anonym’s Approach: Utilizes marketers' own first-party data, operating in a platform-agnostic manner without depending on browser data, thus offering broader applicability across devices.
Key Differentiators:
- Data Source: First-party data vs. browser-collected data.
- Device Compatibility: Platform-agnostic vs. limited to browser environments.
- Data Handling: Confidential computing environments ensuring no direct data sharing.
Quote:
"Ours is kind of platform agnostic. It doesn't really matter where the data was collected by the retailer, as long as they have it, we can use it."
— Graham Mudd [08:45]
Effectiveness of Privacy-Preserving Targeting
Addressing skeptics, Mudd presents evidence supporting the efficacy of Anonym’s methodology:
- Performance Metric: Approximately 30% increase in the efficiency of identifying converters compared to traditional broad targeting, especially in niche markets where precise targeting is crucial.
- Use Case Sensitivity: While broad products (e.g., laundry detergent) may not see significant gains, specialized offerings benefit substantially from privacy-centric targeting.
Quote:
"On average, what that's boiled down to is roughly a 30% increase in the efficiency of finding converters using our method relative to sort of a baseline."
— Graham Mudd [10:10]
Advanced Measurement Techniques
The discussion delves into Anonym’s dual measurement methodologies:
-
Attribution Modeling:
- Purpose: Determine if an ad led to a conversion based on predefined business rules (e.g., last touch within seven days).
- Use Case: Tactical adjustments during campaigns, such as optimizing creative content or targeting strategies.
-
Incrementality Testing:
- Purpose: Assess the genuine impact of ad campaigns by comparing conversion rates between test and control groups.
- Use Case: Strategic decisions on budget allocation and platform effectiveness.
Quote:
"Attribution is often the tactical evaluation, because you need that real-time signal to tweak the knobs during the campaign."
— Graham Mudd [17:50]
Navigating the Regulatory Landscape
Mudd provides a forward-looking perspective on privacy regulations:
- Groundwave Regulation: A multitude of state-level privacy laws in the US, with 19 states already having comprehensive legislation, expected to rise to 25-30 in the near future.
- GDPR Evolution: In Europe, ongoing discussions aim to update GDPR and the E Privacy Directive to accommodate modern privacy-enhancing technologies.
- Regulatory Impact: Regulatory fragmentation necessitates adaptive, privacy-preserving marketing solutions that can comply across various jurisdictions without exhaustive manual adjustments.
Quote:
"Your focus should be real good marketing in the form of great creative, great products, all the fundamentals and building relationships and gathering first-party data."
— Graham Mudd [21:26]
Recommendations for Marketers
Mudd advises marketers to proactively adopt privacy-preserving technologies to future-proof their advertising strategies. Key recommendations include:
- Embrace First-Party Data: Prioritize data directly obtained from customer interactions.
- Leverage Expert Technologies: Utilize specialized privacy technologies to handle data securely and compliantly.
- Focus on Core Marketing Fundamentals: Invest in creative content, product quality, and customer relationships rather than solely on tracking and data acquisition.
Conclusion
The episode culminates with Graham Mudd emphasizing the inevitability of increased privacy regulations and the necessity for marketers to adapt by integrating privacy-friendly technologies. By doing so, businesses can maintain effective ad targeting while respecting and protecting consumer privacy, thereby fostering trust and achieving sustainable growth.
Final Quote:
"Let the privacy folks out there that really understand how to deploy tech to protect that data and those users, let them be the experts in that."
