Michalakis founded Inter-M Traders as a Private Equity Investment Fund (Family Office) and funded numerous oil exploration projects in the United States of America, Gulf of Mexico, Europe, Middle East, and Africa. Aside from Michalakis capital raising and investment delivery undertakings, the projects required the creation of complex financial structures involving other hedge funds and banks located in the United States of America, Europe, Asia, and Middle East.

Michalakis also held the title of Chairman at the China International Investors Association (CIIA).

Michalakis over the years invested in start-up companies and innovative technologies. This became possible by various holding company structures, with experienced operators seeking to partner with the Company for traditional buyouts, recapitalizations, growth and acquisition capital financing. To date, Michalakis has completed over 200 acquisitions and investments.

One of Michalakis core business ventures has been in the development of crude oil and refinery equipment. He started work in this sector during the early 1990s in the Mediterranean and the Black Sea regions. The business and technological advancements that Michalakis helped develop during this time, have now spread across the globe.
