my story
ABOUT ME
I am Mete Berk Çetiner.
​
As an entrepreneur, coach, psychologist, content creator, and HR expert, my passion is lifelong learning and development.
I graduated with dual degrees in Business and Psychology from Koç University on a full scholarship, marking a pivotal moment in my life.
​
I have worked in a leading HR consultancy firm and the HR department of Koç Holding, a Fortune 500 company. These roles have significantly enhanced my expertise in the corporate world.
I specialize in designing adult training and development programs, excelling in assessment, analysis, and action plan creation. Enhancing employee experience in corporate settings is both my passion and area of expertise.
​
Additionally, I hold international coaching accreditations from ICF and EMCC, and I actively engage in coaching and consulting.
​
I introduce myself to my clients as a mentor.
​
I believe that being healthy, happy, and successful requires looking at the whole picture, not just the parts.
​
When working with my clients, I address every aspect of their lives:
​
-
From their psychological health to their professional goals,
-
From their physical health to their personal well-being and family life,
-
My approach elevates their quality of life across all areas.
​
Here are the services I offer:
​
-
Holistic Personal Coaching: I support my clients in achieving their career, personal development, and lifestyle goals.
​
-
Psychological Counseling: I provide professional psychological counseling services tailored to the emotional and mental needs of my clients.
​
-
Career and Business Consulting: I mentor my clients in career planning, professional development, and leadership skills to help them succeed in the business world.
​
-
Physical Health and Beauty Consulting: I offer comprehensive support including nutrition and personal training programs to meet my clients' physical health and beauty needs.
​
This holistic approach supports balanced and healthy development in all areas, offering truly effective transformation and progress.
Additionally, I create various tools and products to help individuals discover and develop themselves on their personal growth journeys. Among these, the OST Mobile App is the most significant and impactful product.
​
Why I Do What I Do
​
2022 was a challenging year for me; it was both my darkest and brightest year.
​
I experienced burnout and felt lost in my career. I was unsatisfied with my work performance and emotional state.
​
However, this period also marked a turning point.
​
I immersed myself in therapy, coaching, personality tests, philosophy, and science.
​
I sought to understand myself, used scientific and tested methods, and gradually gained clarity. It felt like rediscovering myself.
​
I realized that my true motivation is helping people improve their lives, especially in finding clarity and purpose.
​
That's why I started providing coaching and psychological counseling.
​
I also wanted to extend the impact I created individually to a wider audience. I wanted to share the tools I used during my rediscovery process with others. Some of these resources were expensive and difficult to access.
​
Therefore, I decided to establish OST - One Simple Test and created the most comprehensive personal awareness mobile application for free.
​
OST emerged as a culmination of my expertise, experiences, and discoveries. I see OST not just as a business but as a significant venture that allows me to contribute to society and individuals.
​
The OST Vision
​
OST is more than just a mobile app; it is the name of a movement aimed at personal transformation. It's a calling for me.
​
My goal is to provide in-depth personality analyses and personal development tools for free so that they are accessible to everyone.
​
I meticulously crafted each test, drawing inspiration from the best assessment tools worldwide. Using artificial intelligence, I ensured that each test offers both depth and accuracy, based on the research combined with my expertise and experience.
​
My Purpose, Your Journey
​
OST is a tangible expression of my vision and passion;
​
-
it includes over 35 personality tests,
-
detailed analyses,
-
and more than 750 AI-generated art pieces—I now consider myself an artist too—and
-
the in-depth blog articles I write for the newsletter.
​
OST is a community that encourages you to explore, celebrate, and grow.
