Episode Overview

Lewis Reeves, founder and CEO of Walr, on building a data infrastructure platform that powers market research agencies at scale.

Episode Highlights

  • Agentic workflows in practice: Walr has built over one hundred AI agents; one example is a two-agent, one-human pipeline for survey programming where one agent builds the survey, a second verifies it, and a human reviews only the flagged exceptions. Project volumes managed per person have roughly doubled in six months.
  • Democratising AI beyond engineering: Over half of Walr’s 100+ internal agents were built by operations staff, not the product or engineering team: a sign that AI tooling has moved well beyond technical teams.
  • Synthetic data and digital twins: Lewis shares a measured view on synthetic audiences. Walr is running internal trials, but sees customer demand as still cautious, particularly where validation cycles are long, such as political polling.
  • Data quality reframed: Rather than treating data quality as a single issue, Lewis argues for breaking it into distinct categories (survey design, respondent experience, fraud, and inattention) each requiring different solutions.
  • Lessons from scaling: Lewis reflects on the challenges of rapid growth, the importance of following your instincts on change, maintaining close attention to cash flow, and the irony of a market research business that had to learn to listen more carefully to its own customers.
