WHAT IS RESEARCH FOR US?
Research largely means going out into the real world and spending lots of time with people to gain full understanding of their priorities, motives, emotions and values .
Because understanding people in-depth leads to consumer-informed insights.
Consumer-informed insight leads to products, services, experiences and solutions that have true meaning and answer true needs.
Thus we promise that our clients are able to create relevant businesses, build valuable customer relationships and ultimately develop new experience strategies for the future.

"We should not pretend to understand the world only by the intellect; we apprehend it just as much by feeling. Therefore, the judgment of the intellect is, at best, only the half of truth, and must, if it be honest, also come to an understanding of its inadequacy" Carl Gustav Jung

OUR STORY
"Ideas are not just counters used by the calculating mind; they are also golden vessels full of living feeling."
Carl Gustav Jung
We drove our inspiration from the mythological god of emotions: Sentinus. Sentinus in mythology is the god who awakens and watches over the senses of the newly born.
As psychologists, we know that emotions are at the core of the human experience. Our driving passion in founding Sentinus is to understand Turkish consumers as real “human beings” with their emotions and thoughts.
More than 20 years, we've been personally working closely with brands in order to create solid insights and strategies that will help them transform the way they do business. We've been eager to learn, open to new ideas and adaptable to the fast-changing and increasingly complex business environment.
From our inception in 2019, we as Sentinus are ready to tackle any challenge and help you develop strategies for not only sustaining success, but thriving in the future.

FACILITY
Our field services enable us to respond quickly and flexibly to any research requirement.
In line with our clients' needs, we have the capacity to provide studios across Turkey; easily accessible from major airports and interstates, conveniently located near an abundance of restaurants, accommodations and shopping.
I’ve worked with Mahan, Yesim and Songül for over 10 yrs and they are our go-to research partners in Turkey because of their excellence in project delivery across all aspects. Sentinus is a dream team because they combine highly skilled moderation with accurate recruitment and strong project co-ordination. They are always infecting us with their cultural knowledge which helps us get closer to Turkish people and understand their wider influences. It’s rare to find a passionate company who go beyond expectations and truly value partnership. They make us feel at home and their collaboration means we get to deeper consumer truths and enjoy the journey along the way!

I have worked closely with Mahan, Yeşim and Songül on a number of fast-paced and multi-stage international projects and their excellence in project delivery is unmatched, and as a result they have become our go-to partner for projects in the Turkish market.
Mahan is an expertly skilled moderator who is genuinely a joy to watch - as a researcher it can be nerve-wracking to hand over the reins to someone else, but I have complete confidence in Mahan; she approaches each project with passion and excitement, and is able to get to the heart of the Turkish consumer’s needs. The cultural knowledge and strategic recommendations she’s provided us with have been invaluable to the success of our projects and delivering actionable insights to our clients.
