The people behind FitLab
FitLab was born from a very real problem — the coach wanted to spend more time with the people he worked with, rather than on schedules, payments and administrative tasks. His trainee saw how technology could help, and together they decided to create the solution they were missing.

Co-founder, coach and driving force
Kostadin Germanov
I have been involved in sport throughout my conscious life. Until the age of 19, I competed in football. When my competitive career ended, I wanted to stay in sport — but on the other side, as a coach. I graduated from the National Sports Academy “Vasil Levski” in several fields — with a bachelor's degree in Pedagogy and a master's degree in Sport, Fitness and Health. I am currently completing a master's degree in Sports Psychology. I have been coaching for nearly 15 years. I have worked and continue to work with professional athletes and young people from different sports disciplines. One of my favourite parts of the job is the opportunity to work with ordinary working people to improve their health.
Over the years, I have gained experience with people of different ages, levels of physical preparation and goals. I do not believe there is one universal approach that works equally well for everyone. Each person has their own history, abilities, daily life and challenges, and these need to be taken into account when designing their training process.
I believe a coach’s role is not limited to demonstrating exercises and monitoring how they are performed. A coach should be able to listen, motivate and help a person build habits they can maintain over the long term. That is why I continue to develop my knowledge in the field of sports psychology.
The greatest satisfaction comes when a person begins to feel real change — not only in their appearance or sporting results, but also in how they feel in everyday life. More energy, greater self-confidence and the belief that they can achieve their goals. That is the main reason why, after so many years, I continue coaching with enthusiasm and genuine interest.

Co-founder, technology
Bozhidar Kafelov
By profession I am a doctor of dental medicine, but over the past three years I have become increasingly involved in developing specialised software. My interest in technology and the possibilities of artificial intelligence has helped me turn concrete ideas into real, working solutions.
The idea for FitLab came about quite naturally. I train with Kostadin Germanov and I see first-hand how much time and attention organising the training process takes outside the gym itself — booking sessions, communicating with trainees and tracking payments.
This inspired me to create an application that makes life easier both for Kostadin as a coach and for the people who train with him. With the help of AI and modern technologies I built a working solution that lets trainees easily book and manage their sessions and make their payments, without the coach having to spend time on administrative tasks.
For me, FitLab is an example of how technology can solve very real, everyday problems. The goal of the application is to free up more time for what matters most — the coach focusing on people and their development, and trainees enjoying an easier, more convenient and organised experience.
