Oğuz Yılmaz - YilmazHummel


My journey on YouTube started 14 years ago. Y-Titty was the most successful German-language YouTube channel with over 1 billion views, a music album in the charts, concerts and an ECHO. In 2015, I moved behind the camera and firmly settled into my new position as a digital expert with the founding of my own social media and influencer marketing agency. Since mid-2017, I have been working as the manager of Mirella and can offer my help to more artists:inside with YilmazHummel . I take photographs, live vegan and live in Cologne.

Felix Hummel - YilmazHummel


With YilmazHummel I position myself on the side of the artists:inside. In 2012 I produced the German YouTube Original Channel "Onkel Bernis Welt" and in 2013 I started my own YouTube channel "CopyCatChannel". 3 years later, I founded the influencer marketing agency BuzzBird, which is now one of the most successful influencer marketing agencies in Germany. Today, social media and especially YouTube is still my great passion. It is important to me to represent the same values both privately and professionally. I am an incorrigible optimist, vegan as possible and live with my two cats in Berlin.

After more than 3 years of influencer marketing on the brand and agency side, I would like to use my know-how at YilmazHummel and translate it into artist management. Social media is not only enormously important in a marketing context, but is also a great passion for me personally. In addition, there is the aspect of individual support for artists as well as the focus on sustainability and socially relevant topics. I can combine my personal idealism with this very well. I eat a vegan diet - whenever possible - am lovingly cheeky and a wholehearted do-gooder and live in Berlin.



Isabel Glavasevic - YilmazHummel


I have been working in marketing for almost 10 years and have since become acquainted with different perspectives of communication work. In 2015, I came into contact with social media for the first time professionally while working in a PR agency. Since then, I have remained true to the industry & have helped shape influencer:inside marketing in agencies, at a food group & a cosmetics manufacturer. I would now like to bring my expertise & knowledge to YilmazHummel . I am happy to be able to talk about topics that I am also passionate about in my private life. In my work, it is important for me to help shape the industry in a sustainable and strategic way. As an interior lover, I like to redesign my home. At the weekend, I love to discover the latest vegetarian and vegan food spots in my adopted city of Frankfurt.

Sjard Geiersbach - YilmazHummel


Because of my name I am often asked if I am Scandinavian, but I come from a small village near Kassel, where my great-grandparents already owned a few hectares of land and I even went to school with a tractor. So you could call me a true outdoorsman. A sustainable lifestyle has therefore been important to me since my childhood. After a year of voluntary work, I studied economics and languages at the University of Giessen and in Coimbra, Portugal. After working in large food and beverage companies for many years, I now work in accounting at YilmazHummel . I live in Berlin-Kreuzberg. I live in Berlin-Kreuzberg without dogs and cats but with a boyfriend with behavioural problems. In my free time, I like to make music or programme.

Freerk Sitter - YilmazHummel


I come from theater, art and radio, but mostly by bike from Berlin Moabit. For more than ten years now, I have been producing podcasts and telling stories in text and sound for NGOs, politics and cultural institutions. What fascinates me about podcasts is the special closeness and intimacy that emerges between the lines of a conversation. Creating the pauses, the gaps and the digressions that language thrives on are the greatest feat for me. And what words cannot express, the body must dance. Berlin is the ideal place for that, but even though the name comes from the North Sea, my heart is at home in the Lower Rhine.


You can't write Yilmaz without Hummel.


Our aim is not to influence, but to convey content.

We believe that focusing solely on marketing is not sustainable. Promoting good content and helping our creators get their message out into the world is our goal.

We call on companies to be more honest and sustainable.

In order to drive sustainable change, it is not enough to shift the responsibility onto the consumer. We reserve the right to refuse cooperation to companies that cannot demonstrate a sustainability strategy.

Making money is necessary, but getting rich is never our goal.

It is legitimate and important to earn money with your own work. However, we believe that maximizing one's own wealth should never be the goal, neither our own nor that of the creators we work with.

Underpromise, Overdeliver.

It would certainly be possible to acquire the creators with the widest reach if we promised them the moon, but that is not our philosophy. We are honest and stick to the realistic facts.

Racism has no place in our society.

And while we're at it: we're also against all forms of violence, discrimination and hate speech.

We want to be role models.

We believe thatcreators have the power to make the world a better place. That's why we stand up for our values boldly, decisively and loudly.

We live New Work.

Just because it was once said that the working week should have 5 days does not mean that this is a good thing. We are a modern and flexible employer and want to offer our employees a working environment in which they can develop and make all their energy and creativity available to our artists. That is why we have officially introduced the 4-day working week since 01.01.2022.

We believe in the Creator Economy.

Creators are more than influencer marketing. They have long since grown into producers and media entrepreneurs. We welcome and support this development. We believe in the long-term success of the industry and see ourselves and our artists as part of it.

We work for artists, not for brands.

We are a management and thus service provider for our artists. We work for their careers. We do not advise agencies and we do not advise brands. We like to work with partners, but not for them. This is the only way we can guarantee that all our decisions and actions serve the interests of our artists.

Not for sale and independent.

YilmazHummel belongs to Oğuz Yılmaz and Felix Hummel and this will not change. In our founding contract, we have stipulated that no investors or other companies are involved in our management. This way we can always guarantee that all decisions are made for the benefit of our artists.

YilmazHummel has the following focus goals of the UN 2030 Agenda


You can write to us at any time without obligation, no matter what the topic. Here you will find some of the questions and problems that artists often have to deal with:

'Everyone asks where I see myself in 10 years, but where do I actually see myself in a year?'

'How do I best position myself?'

'I just don't have time for anything'.

'I am dissatisfied with my management and need help'.

'I don't dare turn down inquiries'.

'I would like to do more good, but I don't know how.'
