SampleChain was founded in 2018 and is based in New Orleans.

The company’s tools and services are used to prevent sample fraud and duplication, exclude ‘professional respondents’, analyse open-ended responses for negative attributes and prevent bad actors from joining a panel.

Vignesh Krishnan, founder and chief executive, Research Defender, said: “Through a deliberative process we determined that our previous name was not representative of the various ways we help our clients. Going forward we have a clear message as to the costs associated with sample fraud and poorly engaged respondents.”
