About Xyo

We’ve gathered the planet’s top mobile talent together to re-imagine the future of app discovery

We built our first prototype in December 2010. Then we built more (and more). In the end it took us until 2012 to start releasing the type of technologies that make a difference. And that was just the beginning.

We (you, us: humanity) are now in the middle of a large shift towards mobile computing. Mobile apps, not browsers, are the proxy through which we now connect to the mobile internet.

Human publishers try to categorize their apps, but fail to do it accurately. So it makes sense to move towards digital stores that are automatically curated by computer algorithms.

While the traditional Internet focuses on users’ active search queries, the mobile internet doesn’t. On the mobile internet much of your content will be delivered to you without any explicit input in the form of a query. The mobile internet will "know" your interests and predict when it should show you certain kinds of information and content.

After 6 years at various mobile companies (Sponsorpay, DailymeTV, Social Games Observer), Regina knows this: mobile marketing is not a mini version of online marketing, but something completely different. It needs to be based on data, and requires an analytical approach, but it also needs to understand the mobile development process and build messages that consider not only the mobile consumer but the developer too.

With this in mind she roamed the tech scenes of Berlin and Sillicon Valley, talking both to mobile consumers and mobile app publishers, trying to link the right mobile products to the right consumers. With her passion for the topic, Regina also contributes to the mobile community with analyses on the subjects of ASO (App Search Optimization), mobile marketing, and mobile games.


Marcin learned mobile the hard way - building mobile chipsets at the Warsaw University of Technology. His rough ride continued when he joined world's largest mobile content producer, Jamba/Jamster, and was charged with managing insanely complex mobile products. Back then, in the time of J2ME and Symbian, when developers cursed the world for Code Warrior SDK, and CEOs wanted to compete with iPod with music streaming Symbian apps, Marcin was in the middle of it all, trying to keep things somewhat coordinated.

He has stayed in mobile since: managing product development at various startups setting their feet on mobile ground for the first time, and, as Operations Manager at Nokia, coordinated product development for Outdoor R&D and helped integrating it with almost all the other Nokia services.

We're blessed to have Marcin at Xyo now, because there is no more experienced, methodical, and multi-layered product manager on Earth. He sleeps with books about Kanban, Scrum and ITIL under the pillow. His neck hurts. Yet still, with foresight and a hands-on approach, he organizes our days (and nights). Sometimes it feels like he coordinates the whole mobile world...


Obsessed with great ideas and their execution, mobile technology and our ever-changing digital behavior, Elin, a native of Sweden, built her first mobile app in Seoul, Korea, to try to do something different from the start. Since then, everything she's built or designed for mobiles has been different. The app camp she set up for kids to teach them to make their own apps was different. Different also was her Eyeem design that TechCrunch was raving about and which won at The Europas design awards. And the lectures she held at Beckmans School of Design and Bergh's School of Communication were all different.

At Xyo, Elin is heading design, and our users say that Xyo... looks different. As a merciless usability hacker, capable of disrupting screens of all resolutions and sizes and taming colors into breathtaking rainbows of UX, she's taken us aback with every new version of Xyo. First we're floored, then we simply follow (and sometimes to Elin's different parties. So we learned to be different. And we learned also that resistance is futile.

Dominic's life changed in early 2012 when he was gifted his first iPhone. Entranced by its sensitive screen and the magical buttons he could touch on it, he was often to be seen, head bowed, face lit by the glow, alone in a corner, talking to the machine, thus, talking to himself.

A chance encounter with the game Wingsuit Stickman introduced Dominic to the thrilling world of 'the stick people', a people he soon realized live in the phones, and who live lives similar to ours, only thinner and more exhilarating, more violent. Dominic knew instantly that here was a new species ripe for studying. Without delay, he began an intensive diet and training regime designed to shrink his body and organs quickly and without damage, and at the end of Spring 2013 he achieved his 'stick weight' and climbed into his phone.

Once there, after killing some fools, he immersed himself in the local culture and set about realizing some of the dreams that had eluded him in his life outside the phone. Now, Dominic is World Stick Tennis Champion, and a multiple Grand Slam winner, with most of his successes arriving on the sweet green grass of Wimbledon. His trophy cabinet is full, and growing. Inside his phone, he strokes their shiny surfaces with his stick hands, and feels his little stick heart all warm in his little stick chest, like a stick.


Sebastian is still deciding if he's a mobile engineer, a mobile marketer, or a scientist. After 10 years software programming he studied International Marketing – to learn how our soft brains tick. He found them ticking well, but felt a hard part was missing. So he decided to teach, and stayed on at the university to lecture on cross-media marketing and bridge the famous CMO-CTO gap.

Meanwhile he's been building the Mobile Future, and developing mobile strategies and app marketing campaigns for several companies. He successfully brings old brands to the mobile market (Omikron, Vichy, Wallendorf, EDF), and builds mobile presences for online gurus (Fact Finder, 1&1, xpicio). Of course he continues to develop his own mobile apps, just to test what works, you know... (Lohn, HabitSeed)

At Xyo, Sebastian does everything he's always been doing, all at the same time, by carefully designing our user acquisition strategy, measuring, coding, and running around between the devs and the marketing team.

Born in Szczecin (Poland), Ania decided to visit Berlin after finishing high-school, and never left. She specializes in speaking strange languages, and has a degree in Serbian and Croatian Linguistics and Culture. After working for many years as a project manager in the cultural sector (scoping out and organizing international cultural projects for young artists) Ania decided to change sectors and started working for Xyo as the first employee after the founders.

At Xyo she does everything possible; taking care of administration, communication processes, events, bookkeeping, HR and much more. She is Chief Happiness Officer (responsible for the day-to-day cheerfulness of the office) and has so much energy that she donates her leftovers to an ‘energy bank’ for less fortunate people to use. Often seen carrying a camera and leaping suddenly towards objects to photograph them.


Lukasz is a no-nonsense, detail-obsessed software engineer, educated at the Polish-Japanese Institute of Information Technology in Game Programming and System Programming/Robotics. At Xyo, he is The Zookeeper, keeping the animals and architecture fed, cleaned, and under control; giving our business a technological vision.

Whenever he’s not draining the hippo pool, he likes to get away from the smell of straw and other things by going to the theatre; both as a performer and a member of the audience. He speaks Japanese, knows of Kabuki and Okonomiyaki, and likes to 写真を撮る (take photographs), also in Japanese.


Digital designer; curious and passionate about learning and trying new things. She likes to focus on the concept of a project, as she truly believes that design must work, not only be appealing. She owes this "forma mentis" to her studies at the School of Design at Politecnico di Milano, where she learned how to thoroughly and semiotics-wise prove every choice she makes during the design process.

Sara’s constantly inspired by the little details that pass by unnoticed most of the time, especially concerning typography. And her interest in sharing these details with others is the idea behind her project Typefindings.com, a daily typography inspiration resource. She finds inspiration in mistakes, and it's her belief that they help deliver more accurate design products; and uses them as an independent design language, through her experiments with glitches, programming and photo manipulation.

An excellent frontend developer with a passion and eye for details, Łukasz has recently been spending most of his time mining for Javascript. When he’s not chipping away at script in tunnels underground, he loves learning languages, playing around with Photoshop, and battling donuts. Besides this, he has the soul of an artist, and can often be found drumming on things and playing guitar. Will sing on your face if you come within 10 meters of his face.


Mr. Kent is our newest asset at the Warsaw Technology Office. Despite only being hatched a few days ago, his mastery of web development and exceptional (.)net skills have made him a crucial asset to our Eastern Team, and none of them would be able to do anything anything that they do if it weren’t for him. With his forest of eyes and nimble hands he is a natural, supple multi-tasker. He is untiring, never takes a toilet break, and his watchful, hairy presence spurs the whole team on to ever greater efforts.

Mr. Kent has an excellent sense of humour, and many a stressful day has been lightened considerably by watching some poor fool struggling in one of the ‘joke webs’ this lovable colleague likes to spin in inappropriate places.
