At Cosmose AI, we build smart, innovative tech that’s reshaping digital marketing and content distribution. Since launching in 2014, we’ve gone from transforming offline shopping to powering personalized content experiences through AI. Founded by Miron Mironiuk, our journey started with one bold idea—and it’s grown into a feature that caters to people with what they care about most, right from their lock screens.
Our technology and vision have earned Cosmose AI a valuation of over USD 500 million and the trust of iconic brands like L'Oréal, Estée Lauder, LVMH, and Cartier. With users across five continents, we’ve proven that cutting-edge engineering, strong partnerships, and bold innovation drive real global impact.
At Cosmose AI, our teams are building the future of content mobile experiences—starting with KaiKai Lock Screen, our flagship product delivering personalized content to users around the world.
Our people are the core of our success. Their talent has helped us become the most valuable private startup in the EU and a leading Google publishing partner in CEE. This success extends to our strong Asian presence, recently recognized by IAB Hong Kong for the ‘Best Use of Mobile Online Campaign’, reinforcing our growth as we scale globally with award-winning innovation.
Whether your expertise lies in technical, creative, or commercial fields, Cosmose offers the space to grow, the freedom to innovate, and the opportunity to make a real impact.
We’re building something big—and we’re just getting started.
If you’re excited about shaping the future of AI-powered mobile content, we’d love to meet you.
