On-demand research participant recruiting platform across 150 countries
Respondent operates a participant-recruiting platform with 4M+ verified profiles spanning consumer, B2B, and health segments across 150 countries. The tech stack—TypeScript, Node.js, React, MongoDB, AWS—reflects a straightforward web-first platform, but the active project list signals a strategic pivot: production-grade ML pipelines, novel engagement models, and conversational AI sit alongside enterprise sales infrastructure (ABM, RevOps funnel work, complex deal closing). The hiring mix—engineering-heavy with emerging data and sales roles—mirrors this dual focus on platform scaling and enterprise motion, though recent hiring velocity has slowed.
