Sergei Polonskii is one of the most recognized real estate developers in Europe. His career has been defined by large-scale architectural ventures, international projects, and a consistent willingness to pursue ideas that others considered premature. His reputation was built on bold execution and an ability to see potential where others saw risk.

His involvement with Mycomysticism grew from a personal alignment with the organization’s mission. For Sergei, the transition from building physical structures to supporting spaces designed for inner transformation was not a departure from his career. It was an extension of it.

As a member of the Advisory Board, he advises on temple development and global expansion strategy. He is a key partner in one of the organization’s most significant upcoming projects: the construction of a sacred temple in Mexico. His role in this initiative is hands-on, combining his development expertise with a genuine commitment to creating spaces where ceremonial work can take place with the dignity and permanence it deserves.

Sergei brings to the team what he has always brought to his projects: scale of thinking, energy, and the conviction that what you build should outlast the builder.
