PP&A designed an interview guide in eight sections: the interviewee's role in data integration for advertising, integration processes and the balance of real-time and batch processing, privacy and security measures for unconsented and sensitive data, advertising performance and return on investment under privacy constraints, clean rooms and advanced use cases, vendor and ecosystem perspectives, and the outlook for the next few years.

Between March and May 2025 the team led in-depth interviews with four insiders from leading CDP, CRM, product analytics and cloud vendors: a former head of product engineering, a principal digital strategist, a former customer-onboarding manager and a former director of technical support engineering, based in the United States and Ireland. PP&A synthesized the conversations into a report organized around seven themes: regulatory mandates, compliant data acquisition, the data security foundation, architecting for privacy, balancing effectiveness with privacy, governance, and market evolution, each pairing observations with implications for platform vendors.

The client received a report on how privacy rules shape advertising data, seen from inside the vendors that build and support CDP, CRM, analytics and cloud platforms. It covered how regulation changes consent capture, deletion and retention, and how platforms protect sensitive and unconsented data. It showed where privacy controls are hardest to build into existing technology stacks and how advertisers keep campaigns effective under privacy constraints. It also described the governance practices organizations rely on and how the vendor landscape and privacy-enhancing collaboration models are likely to evolve. The broad message was that governance matters as much as technology.

Each theme paired observations with implications for platform vendors. Together they gave the client an insider view of vendor practice as input to its own advertising and data-platform strategy.
