Walr Tech Stack

Human-in-the-loop research operations platform for market researchers

Market Research London, England 51–200 employees Founded 2020 Privately Held

Walr automates the operational backbone of market research—survey design, sampling, fieldwork, data validation—using Python, SPSS, and React. The company is hiring aggressively across data and engineering (7 roles in 30 days, mostly senior), signaling platform expansion rather than services scaling. Pain points around gross margins, cash collection, and weekend project complexity suggest Walr is transitioning from pure-services toward a software-driven unit-economics model.
