Let's Talk

Who we are

The rest of our story

Udonis was founded in 2015 with a simple mission - effectively advertising businesses online. Hundreds of thousands of marketing dollars went into generating revenue for traditional businesses before we decided on a niche in 2018. That niche was the booming mobile game market.

Since then, we have been acquiring users for some of the biggest mobile gaming companies in the industry, as well as for hundreds of minor studios. We are most proud of those that went from small to multi-million businesses with the help of our marketing, such as Tastypill or Playsome.

Mobile marketing has changed a lot since the booming of 2018, but Udonis has been successfully adapting, embracing new technologies, creating solutions, and staying at the forefront of mobile game user acquisition.

In addition to our core service as a mobile game marketing agency, Udonis also owns Meusis - a company that still does what we started out with in 2015 - marketing traditional business online.

What we do

Performance guided by data

We provide game makers with field-tested mobile game marketing services for profitable user acquisition at scale. This includes creatives, media buying, analytics, and ongoing optimization aimed at achieving your goals.

Since 2018, Udonis managed more than $500,000,000 in media spend and creative budgets to acquire users for mobile gaming companies, from studios owned by Activision Blizzard and Take-Two Interactive to indies such as Voodoo, Tastypill, and many others.
