London-based entrepreneur Dmytro Makarov built his marketing powerhouse on a philosophy he calls GMG: Grind. Mastery. Growth. What started as freelance projects has grown into an international agency with more than 100 employees, serving clients such as BMW, Intel, Durex, Domino’s, Nivea, Hugo and the Ukrainian large brand Kyivstar.
Makarov credits his success to a combination of disciplined mindset and biohacking practices. He says the GMG concept frames not just his business, but his personal development as well.
“Grind stands for constant work on yourself, your skills, your business. From first freelance projects to running an agency, every step came from persistence,” he explains the first G in GMG. As Makarov explains further, mastery means developing expertise in marketing, analytics and management, while growth reflects not only financial gain but also personal and team development. This philosophy, he says, helped him navigate the competitive worlds of digital strategy, influencer marketing and performance media.
Biohacking Beyond Business
Dmytro Makarov is also a strong believer in biohacking, a practice more often associated with athletes than entrepreneurs. He applies it to maintain high performance in business, blending structure with adaptability.
He explains that the most effective worker, whether in sports or business, is not a “robot with a regimen,” but someone with “a smart balance between workload, recovery and personal needs.”
Biohacking, in Makarov’s view, is not about extreme discipline or strict systems. Instead, he sees it as a framework for creating routines that support focus and flexibility. His own approach includes morning and evening rituals without gadgets, a whole-food diet with minimal sugar, and regular exercise to manage stress.
“In the end, biohacking is not about controlling every second. It is about an internal ecosystem with room for rest and flexibility, but also internal discipline that keeps you focused,” the entrepreneur explains.
Tools, Supplements and Data
Experimentation has always been central to Dmytro Makarov’s approach. From his early days as an independent consultant to leading an international agency, he has tested tools and practices on himself before bringing them into his professional or personal life.
He has tried intermittent fasting and supplements but cautions against relying on quick fixes. “Any supplement is just a tool, not a replacement for sleep, nutrition, recovery and balanced workload,” Makarov notes.
Technology also supports his methods. He uses wearable devices like Whoop to track heart rate variability, sleep and stress. These data points, he says, allow him to manage workload and prevent burnout. “The device adapts its recommendations to you; it is not just stats but a personal algorithm,” he explains.
Persistence and Adaptability
The journey of Dmytro Makarov underscores how persistence, skill development and adaptability can transform self-taught expertise into a global business. His GMG philosophy is more than a catchphrase, it is the foundation of his leadership style.
For the entrepreneur, the combination of mindset and biohacking is not just about staying sharp, but about building a sustainable future. By blending discipline with flexibility, he demonstrates how entrepreneurs can grow without sacrificing health along the way.
