What our clients say
"It is difficult when you have to test regionally around the globe when you are based in another country (being in the U.S.), needing to rely on vendors to move forward with your testing plan. We had issues with our initial recruiter for testing participants in Sao Paulo so for our next phase, we chose Mercedes Sanchez as our vendor to recruit our specified participants along with securing a testing lab. Mercedes and her team went above and beyond on every level and they were always available to provide us with the utmost service in communication, process, and delivery. We typically recruit 30% more to make up for no-shows or any technical difficulties but we were able to get our study completed on schedule without having to make up any invalid sessions because of their due diligence. I recommend any and all usability services provided by Mercedes Sanchez and I look forward to working with them in the future."
Linda van Nifterik, User Experience Designer, Idea Integration
"Mercedes Sanchez carried out user testing in Brazil for a comparative
study on touchscreen mobile phone interfaces. From start to finish,
the whole team was a pleasure to work with. The user sessions were
conducted in a professional manner and the reporting was very
insightful, with clear, actionable findings and recommendations.
Mercedes expert knowledge, both of the Brazilian market and as a
usability practitioner, is invaluable. We look forward to the next
project."
Gemma Boguslawski, User Experience Consultant, Serco Usability Services

“Mercedes Sanchez conducted a User Experience-Test in Brazil for our consultancy. This project was carried out to the highest standard. Her reliable and accurate way of work made her an excellent partner with outstanding analytic and writing skills. Her deep knowledge of the Brazilian culture was very helpful for us and we would appreciate to be working with her again.”
Claudia Rummel, Senior Consultant User Experience, SirValUse Consulting GmbH
"We are very satisfied with the professional dedication and technical expertise shown by Mercedes and her team. The services provided to us during a mobile phone usability project have been of very high quality. During the course of project, as critical issues have arisen, the team has consistently responded quickly and effectively to keep schedules on track. This has been a very successful and productive working relationship."
