A Little About Our History

BDI Research was founded by Rosa Dalet in 1992 and, rapidly became a trusted choice for data collection and research services in Spain. In 2002, building on its success, BDI opened its first focus group facility in Barcelona followed by Madrid, in 2005. In 2006, Schlesinger Group chose BDI to support their client research needs in Spain and a long-standing and trusted partnership was formed.

In 2017, BDI Research officially joined the Schlesinger Group. Under Rosa’s continued direction, and through its client-centric approach, BDI Research continues to deliver outstanding solutions for its clients in Spain and worldwide.

The acquisition by the Schlesinger family has allowed for extremely effective and positive merge of dynamic and talented international teams. We have already learned a great deal from each other. Our clients now benefit from the collaboration, resources, population access, partnerships and early adoption of innovative technologies that come with being part of Schlesinger Group.
