Episode Overview

Fairgen founder Samuel Cohen on synthetic data, digital twins and how AI is making market research more accessible to more organisations.

Episode Highlights

  • A taxonomy of synthetic data. Samuel maps the space across two axes: methodology (directional to foundational) and stakes (low to high), showing why different approaches suit different research contexts.
  • Why “boosting” has become standard. Fairgen’s augmentation technology is now used by brands including T-Mobile and L’Oréal to dramatically expand the number of segments they can reliably report on, with three years of rigorous statistical validation behind it.
  • The problem with fully synthetic panels. Samuel explains why prompting LLMs to simulate survey respondents produces poor results: large language models are “averaging machines” that flatten individual variance and produce near-identical responses.
  • How Fairgen builds category-level digital twins. Each twin is anchored to a real person and enriched with category-specific survey data, clickstream, transactional and live news data, refreshed quarterly to maintain accuracy.
  • The democratisation of research. AI-powered tools (including digital twins and AI-moderated qualitative research) have the potential to make insights accessible to startups, SMBs and underserved markets that have historically been priced out.
  • Founder lessons. Samuel shares two core pieces of advice: challenge every assumption, and invest consistently in building relationships and networks.
