Get to know us
Our story began around 2003 in Hungary, where we were involved in the operation of several local municipal newspapers. In addition, we participated in numerous graphic design and content creation projects. A significant turning point for our company occurred in 2007 in Canada, when we started working in an international environment. Since then, we have been managing international projects with openness and experience. Discover our company’s history, key milestones, and achievements!
Hungary, Budapest
2003 - 2006
In the beginning
Initially, our company participated in projects related to press products, media content, event organization and education. We quickly developed, and within a few years, our monthly publications reached a readership of 150,000.
Canada, Toronto
2006-2012
In the world of creativity
We participated in numerous graphic design, web development, and photography projects. During these years, responding to our clients’ needs, creativity and solutions tailored to unique requirements became part of our daily routine.
South Korea, Seoul
2012 - 2017
A bridge between cultures
We supported Western businesses in entering the Korean market. Our projects included graphic design, web development, event planning, and education. We are particularly proud that in 2013, we were ranked among the top ten foreign startups with our local tourism decentralization project, called Indeed Korea.
Ireland, Dublin
2017 - 2019
In a multinational environment
Our company, with international experience, began its operations in one of Europe’s busiest cities, Dublin. Here, we worked for multinational companies such as Kodak, Deliveroo, UberEats, etc. This creative work in a corporate environment provided us with experiences that greatly contributed to the success of our later projects.
Hungary
2019 - present
Managing large investments, managing large projects
The reason for our return to Hungary was to seize untapped business opportunities. It was clear to us that we could manage the projects of South Korean investors coming to the country efficiently and without cultural barriers. In recent years, we have worked with almost all the major global Korean companies arriving here, including Samsung SDI, SK ON, LG, and Hanwha.
