Mardien helped us plan and strategize our operation. As a start-up we need to re-organise often. She is very easy to communicate with, understands what the business is about and pulled up her sleeves after our first meeting. I will definitely hire her for consultancy in the future.

Mardien is a smart and driven person who likes to work at the cutting edge. She also likes to make sure that new products and ideas hit the market, and are therefore shipped! She also has a fun personality so working with her is always a pleasure.

Mardien is highly professional, taking both a creative and detailed approach to product strategy initiatives. She excels at capturing business requirements, interviewing users on their needs and pain points, and reviewing the market landscape and then applying that understanding to product strategy. Mardien is someone you want on your team.

For the last three years, I've worked with Mardien. Initially, we collaborated on the MRS mobile optimization research project. Since May this year, Mardien has been a valuable contributor to the MRS Global Data Quality program, particularly in identifying internal solutions for data quality and integrity issues. Mardien's deep expertise and dedication in both data and digital domains, her leadership, and willingness to go the extra mile have been truly impressive throughout our collaboration.

For 2.5 years, I partnered with Mardien and her team at Toluna. Together, we improved the data-loading experience for mutual Fortune 500 customers. I was highly impressed with Mardien's communication and organizational skills throughout planning, building, and testing. She used customer feedback to make ongoing improvements, enriching the end-user experience. Our shared customers still benefit from the integration and data to this day. Mardien's strong product mindset made working with her a pleasure, and I look forward to future collaborations."
