WHAT DOES OTAKOYI MEAN?

[o t a k ó j i :] You might be thinking, “Is it Japanese?” — but think again! OTAKOYI is actually a vibrant Ukrainian word used to express surprise and excitement.

In Ukrainian, it’s written as ОТАКОЇ. What makes it truly special is the letter Ї — a unique character in the Ukrainian alphabet. Today, this letter has become a powerful symbol of Ukrainian identity and freedom, often seen in graffiti, fashion, and art as a bold statement of independence.

THREE DIVISIONS. ONE SUCCESS STORY.

The OTAKOYI ecosystem is a synergy of three specialized branches united by one mission: empower businesses through technology, creativity, and intelligence.

OTAKOYI SOCIAL IMPACT

image
“St. Nicholas Won’t Forget You” by the Maltese Aid Service

Each year, OTAKOYI employees participate in a charity initiative for St. Nicholas Day, choosing letters from children in need — now often from displaced families or those in frontline areas. Together, we work to fulfill these children's wish lists by purchasing warm clothes, books, school supplies, toys, and, at times, making their unique dreams come true.

OTAKOYI Shelter

At the onset of the full-scale invasion, part of our office was converted into a temporary shelter for volunteers, displaced families, and employees from eastern regions cities. We set up sleeping areas, showers, and provided essential supplies. Over time, our open space evolved into a full-fledged humanitarian hub in partnership with the 4Ukraine foundation.

image

Charity Week

Throughout the years of the full-scale war, we’ve organized fundraising and volunteer events to support Ukraine’s defenders. These efforts included charity auctions, a drone assembly workshop with HERO7 LAB, first aid training sessions, creative masterclasses, and crafting camouflage nets with the "Porokhova Vezha" community. The funds raised were donated to organizations like Help a Hero or used to support our mobilized team members serving in the Armed Forces.

OTAKOYI Tree

As part of a charitable project by the Lviv City Council, we donated funds and earned the honor of planting a personalized tree in the heart of the city — a small but meaningful symbol of rooting for the future.
