Mark Ritson on Using Synthetic Data for Marketing Strategy
In this article, marketing expert Mark Ritson explains how synthetic data, generated by AI, can transform marketing planning. Using a practical example of a hypothetical marketing plan for Tabasco in Canada, he walks through six steps: market research, segmentation, targeting, positioning, setting commercial objectives, and building the marketing mix. Ritson highlights that synthetic data can simulate thousands of consumers at a fraction of the cost of traditional research—about $10,000 compared to over $2 million. He emphasizes that while synthetic data is not a substitute for real consumer data, it can help marketers understand markets, identify target audiences, and develop strategies more efficiently. Ritson is an investor in Evidenza, the company behind the planning platform '10 Slides', which he describes as a major advance in brand management. However, he also cautions that marketers should validate synthetic findings with real data.
The article highlights the growing use of synthetic data in marketing strategy, which could disrupt traditional market research and planning. It is relevant to marketers and martech vendors, but it is not a breaking news event; it's an educational piece from a well-known industry figure.

Synthetic Data's Role in Customer Research
The article explains how synthetic data — AI-generated, statistically representative datasets — can accelerate and broaden customer research by simulating audience responses, enabling synthetic focus groups, virtual personas, and digital twins. It argues synthetic data is most useful where real data is scarce or expensive to collect, and recommends starting with focused pilots tied to manageable decisions (for example, message testing or early product concept validation). The piece warns synthetic outputs reflect the quality and biases of their inputs and should inform but not replace real-world validation or human judgment. Governance, transparency about source data and model assumptions, vendor evaluation, and validation steps against observed behavior are presented as prerequisites for trust and long-term adoption. Over time, organizations that treat synthetic data as a disciplined capability can speed experimentation and make real customer input more targeted and valuable.
Synthetic Research: Promise With a Catch
This MarTech analysis examines the rapid rise of synthetic research—using generative models and synthetic personas to produce market and product insights—and the tradeoffs between speed/cost and scientific rigor. The synthetic data market is projected to grow dramatically, and many insight leaders plan to adopt synthetic approaches for scale and niche sampling. But off-the-shelf LLMs (e.g., ChatGPT, Claude, Gemini) can introduce bias, homogeneity and overly positive responses (the “Pollyanna Principle”), producing outputs that are difficult to validate. The article highlights techniques to improve reliability: fine-tuning models on proprietary survey data, applying a train-synthetic, test-real (TSTR) validation approach, and enforcing governance, transparency and persona provenance checklists. Case studies and experiments (including Stanford/Google DeepMind results and a Dollar Shave Club example) show promise when synthetic methods are benchmarked and verified against real-world data.
Agencies Adopt Synthetic Audiences for Media Planning
The Media Buying Briefing reports that synthetic audience adoption is accelerating among agencies and clients. Goodway Group has partnered with data company Arima to incorporate insights from synthetic consumer populations into media planning processes, allowing incrementality tests in simulated environments before real-world activations. Other firms including Vurvey Labs, Limitless Labs, WPP, Dentsu, and Code & Theory are also using synthetic data for market research, creative development, and media buying. The article cites examples such as Magnum, Vans, Kenvue, and Sacheu using synthetic personas. Experts caution that synthetic insights should supplement, not replace, human judgment. WARC data highlights growth in social ad spend, and the briefing notes new launches like Brandtech Data and acquisitions by SAMY and MSQ.
