About Us

373 is the country code of Moldova, the birthplace of founders Iulia & Stas. It’s beautiful, yet the poorest country in Eastern Europe, and even one of the poorest countries in the world.

Growing up full of ambitions, in 2011 Iulia and Stas received a chance to immigrate to the United States - the symbol of freedom and opportunity. Since the very first day, the US felt like home and felt like the place where Iulia and Stas can live up to their full potential. 

Years of hard work, ups and downs, new beginnings, and failures only kept making the goal to achieve something great even stronger.
