What Respondi does
Respondi is a market research services and technology company headquartered in London, UK, founded in 2005 with a current headcount of 51-100 employees. The firm operates within a broader pan-European research group (associated with the Bilendi group, listed on Euronext Paris under ticker ALBLD) and provides research institutes and advertising agencies with access to consumer panels across 44 countries. Otto Hellwig is identified as Founder, CEO, and Corporate Integration Director.
The company's core asset is a tailor-made proprietary technology platform designed to deliver daily access to qualified audiences for market research purposes. Around this platform, Respondi offers a layered product set: the base Bilendi Platform for panel access and data collection; Bilendi Discuss for qualitative community engagement (referenced through a Stabilo consumer-goods case study); Niche Sampling and Niche Country services for targeted audience and country-specific research; an AI-augmented offering; and Qual Deep-dive qualitative research. Services span from simple sample-only delivery to full-service market research, including advertising effectiveness measurement.
Respondi operates through direct sales to enterprise research buyers rather than disclosed self-serve channels. The firm maintains wholly-owned regional subsidiaries across at least 13 European markets plus a US entity, supporting local project management and panelist recruitment. Pricing is not publicly disclosed and no revenue figures are available in the source material; the explicit language on the US-facing website emphasizes 'sample only' through 'full service' as the service continuum, with customer logos (e.g., Stabilo) limited in number within the supplied data.
