Our values

Go the extra mile

We believe in doing our job as best we can and going beyond our and others’ expectations. We didn’t get here by being average and we cannot maintain a leading position without striving to be the best. Whether fostering better communication in your team, spending extra time to get an additional metric for a customer report, or helping a client debug an issue unrelated to our products, we go beyond the call of duty.

Go the extra mile
Try, (Fail), Learn, Improve

Try, (Fail), Learn, Improve

Failure is a key to our success. When we started, we knew nothing about P2P, video delivery, or CDNs. In less than two years, we have become renowned experts in the industry with the best technology on the market. We have made many mistakes in the process but have taken the risk to put ourselves out there, learn from each misstep and come out stronger each time.

Embrace feedback

Open feedback is a key to learning and improving oneself, one’s team, our product, and the company as a whole. Feedback can be one-on-one, in a group retrospective, between a lead and a team member, or even between teams. No one should consider themselves above feedback - managers and executives included - as everyone can bring new and valuable perspective. Feedback should be given and received honestly without fear, ego or personal offense. It is an opportunity for us to grow.

Open communication is fundamental to effective feedback. It is each of our responsibility to encourage information sharing within the company, and to create an environment of respect and understanding so that everyone feels comfortable talking about any subject.

Embrace feedback
Alone you go faster; together we go further!

Alone you go faster; together we go further!

You may be the smartest, most talented, or most experienced person in the room, but you will never go as far as a team working together. Our greatest successes are achieved through teamwork, and everyone has something to bring to the table. We work every day to nurture the potential of each team member and constantly improve the way we work together.

We all have common goals, so let’s work together to achieve them!


You can achieve great things and still have fun. Before starting Streamroot, the founders were friends in college and have tried to promote an atmosphere and ways of working together as more than just colleagues. The best teams are those with great chemistry, and that’s why we do organize a lot of team building activities. The team also enjoys gathering spontaneously for after works, sports sessions, movie nights, festivals.

We also try to bring a little of our dynamism and laid-back atmosphere to a pretty serious industry. We’re simple, honest and respectful to our customers, partners and competitors - and are the first to invite everyone for a beer at the end of the day!



Diversity is a well-known principle, but as part of an international team inside an international company, it has a special meaning to us. Diversity is about inclusion – welcoming different opinions, diverse backgrounds and points of view. It is also about embracing new ideas and creating a culture that fosters innovation by valuing those differences. Our customers are from all over the world, and having diverse representation in our team helps us serve them better.
