TubeScience has appointed Emil Bielski as General Manager, International, marking its entry into the UK and European markets.
Based in London, Bielski will report to Co-Founder and President Philip Buerger as the US social and performance creative studio expands across Europe, the Middle East and Africa.
His appointment brings a former agency chief into a business that works across more than USD $2.6 billion in annual ad spend on social channels. TubeScience has spent more than a decade working with eCommerce brands and developed a model in which it is paid on outcomes rather than retainers.
Before joining TubeScience, Bielski was Chief Executive Officer of Spark Foundry. Earlier, he led Croud, where the agency won accounts including Compare the Market and opened offices across the Middle East.
TubeScience focuses on large-scale creative testing and production for digital advertising across platforms including Meta, YouTube, TikTok and connected TV. It has also built a library of 1.5 million advertisements, which it uses as a dataset to assess how social and video advertising influences consumer purchasing.
The company operates a 100,000-square-foot studio in Los Angeles, bringing together in-house teams and staff from the film and television industry. That setup supports the production and testing of large volumes of platform-specific creative work.
European push
The move comes as advertising and media groups face growing pressure from brands to demonstrate clearer returns on social video spending. It also reflects continued interest in creative testing models that link production more closely to measurable sales outcomes.
Founded by Moshe Moschbacher and Philip Buerger, TubeScience works with brands in sectors including health, fintech and consumer services. Its client roster has included Unilever, hims & hers, Uber, Il Makiage and Capital One.
Bielski said the company sees an opening in the market as brands reassess agency relationships and demand stronger performance from video and social campaigns.
"We are in the era where brands have to diversify or decline, but they are being let down by the current agency eco-system. TubeScience's outcomes-based model ensures effectiveness is hardcoded. Delivering 1.5 million diverse ads that have driven the growth of the biggest eCommerce brands in the world," said Emil Bielski, General Manager, International, TubeScience.
"I can't wait to bring this unparalleled expertise to the UK market and help brands transform their approach to video and social performance creative," Bielski said.
Buerger said the appointment is central to the company's international plans.
"We are really excited to have someone of Emil's profile and experience onboard. His leadership is critical as we bring the unique TubeScience model to a global audience and continue to scale our international footprint," said Philip Buerger, Co-Founder and President, TubeScience.
"His background sits squarely at the intersection of performance media and agency leadership, making him a natural fit to introduce TubeScience's model to European markets," he said.
