Confidence and a can-do attitude

We are closely networked international natives who feel comfortable with pace and love to think. We have been in the business long enough to know where we can push boundaries, and we are curious enough to strive for that very goal.

Experience, time, and depth
The story of I+E Research GmbH begins in 1994. Barbara Götz founded a fieldwork agency in Berlin Kreuzberg which she led for the following five years, managing to garner a formidable reputation in the market after a short start-up phase.

The success of the first fieldwork agency and growing expertise led to the establishment of a new studio in the West of Berlin, close to Kurfürstendamm and the legendary Bahnhof Zoo, in 1999. Barbara Götz and Interview and Exploration Julia Otte GmbH merged to form I+E Interview and Exploration Berlin GmbH.

The popular studio in the historic Bikini building, boasting a view of the Berlin Zoo as well as the Kaiser Wilhelm Memorial Church, became the fieldwork agency’s home for eight years. 2006 saw the opening of Berlin’s new Central Station, initiating a period of urban restructuring and the development of a new city centre. Thanks to its successful business, the company was able to relocate to Potsdamer Platz in 2007. Here, in the city’s historical centre and the place where the Wall formed a harsh dividing line between East and West, our current state-of-the-art 650-sqm studio has been located ever since – right in the middle of Berlin’s revived, architecturally diverse, and ever-changing heart.        

In late 2010, the company was renamed I+E Research GmbH. Currently, we coordinate some 500 nationwide qualitative market research projects per year, with a focus on healthcare, trend research, and B2B/B2C.

In 2017, we set up shop in Düsseldorf, a vital location within Germany’s largest metropolitan area. Originally a part of the successful core business of Interview and Exploration Julia Otte GmbH, I+E Studio Düsseldorf offers the same range of services available in Berlin as well as the right mix of long-standing experience and modern quality management.    

While we enjoy great stories about the past, an exciting future is much more important to us.

Even behind the scenes a strong gang.

Barbara Götz


Shortly after graduating with a degree in business management in the early 1990s, Barbara Götz moved to Berlin, where she set up her first company in the area of market and social research in Kreuzberg. In 1999, she founded I+E Interview and Exploration Berlin GmbH – today’s I+E Research GmbH. Two decades later, she is still known for her energy and wealth of ideas: Privately an ambitious equestrian with a significant green thumb (that garden!), Barbara is also a true expert on the best retreats and destinations for an extensive outing in Berlin and its surroundings. With her Bavarian esprit and an excellent network within the industry, she constantly challenges herself with projects that others would gladly shy away from. It would be her pleasure to draft you a proposal.

Marco Perschon

Recruitment & Trend Research, Consumer Goods

Following his stays abroad in Chicago and Shanghai, the desire for a second university degree led Marco, a trained journalist, to Berlin – this time to become a sound engineer. Since 2011, he pours his passion and night-time hours into his work as label manager, record producer, and DJ for a Deep House & Techno label in Berlin. Marco spends his daytime with I+E Research and manages recruitment for trend research and consumer goods studies. Driven by his never-ending curiosity and keen eye for creative people, he manages to nail down even extremely hard-to-find urban target groups and easily inspires them to participate in our research. The little spare time Marco has, he spends studying and practicing multiple Yoga techniques like Hatha, Bikram, Yin, Vinyasa, and Ashtanga. In fact, it is safe to say that Marco has transcended the necessity of sleep or rest and, thus, has reached a state of yogic equilibrium.

Franz Einerhand

Technical Supervisor & Service Manager

Franz Einerhand has been responsible for all things technical at I+E Research since 2000. He will gladly answer all of your questions regarding your day at our studio, the catering, or any queries you might have as to the technical setup. Clients and employees alike appreciate his helpfulness, his jovial nature, and the exquisite cakes he regularly transports from his Spandau kitchen to Potsdamer Platz on one of his scooters.

Silke Voigtmann

Project Management & Recruitment

For a quarter of a century, Silke Voigtmann has worked in qualitative market research – a fact that should have earned her a waxwork effigy at Madame Tussauds. During this time, Silke has mastered a variety of positions and projects, thus bringing an experiential as well as professional expertise to the table that is simply priceless. Born and raised in the arguably picturesque small town of Radebeul, West Berlin kept calling – a call that Silke happily accepted and that secured her a front row seat for the German reunification / fall of the Berlin Wall only two years later. Her profound relationship with market research, which already started during her communication studies, was only put on hold for a three-year adventure as an accompanying crew member of Cirque du Soleil. Now that Silke is back, we will give our best to make her stay for good!

Andreas Hüffer

Senior Moderator

Andreas Hüffer has been an integral part of the I+E Research team since the 1990s. After graduating with a degree in linguistics and communication science, he completed further training in psychotherapy and Balint group moderation at a university hospital for forensic psychiatry. Almost 20 years later, there is hardly a medical indication he has not worked with. From widespread afflictions to rare diseases, he will not only moderate your interviews, but is able to reveal hidden insights based on his vast experience from the hundreds of studies he has conducted. A passionate moderator, Andreas Hüffer loves people and exchange. Feel free to see for yourself and strike up a conversation about basketball or the history of archery. Our service team will go ahead and chill a beer for you in anticipation.

Michael Feser

Head of I+E Studio Düsseldorf

Michael Feser is a trained copywriter and has been working in market research since 1998. Having 15 years of experience as head of studio and a serene Rhinelandian mindset, Michael will be happy to answer all your questions and provide advice on the equipment, technology, and catering available at I+E Studio Düsseldorf. When he isn’t working to ensure seamless studio services together with his team, he pursues his passion for cooking – with a lot of ambition! To Michael, complex research designs requiring tailor-made spatial and technological arrangements are nothing to be afraid of: No matter how good or bad the weather is, he rides his bike to work every day.

Pony Schwedler

Project Management & Moderator

A self-proclaimed language aficionada, Pony joined our team as a project manager and moderator alike. She completed her BA in socio-linguistics as well as her MA in social and cultural anthropology at Freie Universität Berlin. Both degrees have prepared her well to work with a diversity of customers and professionals. Her previous engagement in an interdisciplinary research project at Freie Universität and Charité from 2015 to 2017 has sensitized Pony toward the medical research context. Her more recent experiences with our clients and respondents, ultimately, have sparked and continuously strengthened Pony’s passion for qualitative market research. After work and together with her cat, Pony stretches away any worries in her Yin yoga practice. And, quite frankly, who wouldn’t like to replace ‘downward facing dog’ with ‘downward facing kitty’ …?
