Adtech Firm Cites 5.6x Lift on Safari and Firefox
Performance adtech firm Symitri reports a 5.6x conversion lift for campaigns running on Safari and Firefox browsers, which have deprecated third-party cookies. The results for wellness brand TRUBAR were attributed to the firm's AI-driven audience intelligence and premium supply paths, suggesting that privacy-centric optimization can yield results in signal-constrained environments.
- Safari began blocking third-party cookies by default with the introduction of Intelligent Tracking Prevention (ITP) in 2017. Firefox followed suit in 2019 with its Enhanced Tracking Protection (ETP) feature. Google started disabling third-party cookies for 1% of Chrome users in early 2024, with a full phase-out delayed. - "Signal loss" describes the degradation of user data available for ad targeting and measurement due to factors like cookie deprecation and privacy regulations. This loss of data presents significant challenges for personalization, retargeting, and attribution in programmatic advertising. - Symitri, the adtech firm mentioned, operates a real-time data clean room, allowing advertisers and publishers to match first-party audiences securely. The company raised a $5 million Series A round in May 2024 and also acquired TRUSTX, a marketplace for programmatic inventory. - Wellness brand TRUBAR, founded by Erica Groussman, scaled to over $50 million in sales with minimal traditional advertising before being acquired by Simply Better Brands Corp. in 2021. The company's growth strategy has focused on creative branding, direct-to-consumer sales, and securing distribution in nearly 20,000 retail stores, including major retailers like Costco and Walmart. - Google's Privacy Sandbox initiative aims to create web standards that allow for targeted advertising without relying on third-party cookies. Key technologies include the Topics API for interest-based advertising and the Attribution Reporting API for conversion measurement, which were made generally available in September 2023. - Key themes from London Tech Week 2024 included the business impact of AI, the potential of quantum computing, and the importance of diversity and inclusion in the tech industry. London has attracted over 1,700 tech foreign direct investment projects in the last decade, more than any other city. - The 2025 Formula 1 driver market has seen significant moves, with Lewis Hamilton's switch to Ferrari being the most notable. Carlos Sainz remains a key figure with potential moves to either Williams or Sauber/Audi, which will trigger further changes across the grid.
