Creamsource, renowned for its Vortex series of cinematic lighting, is laying the groundwork for its next phase of growth with the addition of Markus Zeiler as Group Managing Director. He joins at a pivotal moment, as the company expands into new markets, deepens its R&D efforts, and develops the next generation of tools shaped by the needs of filmmakers, partners, and production teams.

Since 2005, Creamsource has been guided by its founders, Tama Berkeljon and Sasha Marks, whose hands-on engineering, product philosophy, and deep curiosity continue to define the company’s DNA. Their long-term vision centers on innovation, new product lines, and responding to what the community is asking for. With Markus stepping into operational leadership, Tama and Sasha gain more dedicated space to stay immersed in the pipeline of new technologies and tools. His role stretches across everything required to bring a product from development into the world, giving the founders the freedom to stay focused on future innovation.

Markus’ experience spans LED development and lighting leadership at ARRI, as well as business growth and expansion at MBS Europe. He has overseen product and operations teams, led major global initiatives, and helped drive the worldwide adoption of LED lighting in film and television. His combination of operational discipline, technical fluency, and industry insight strengthens the foundation around Creamsource’s growing roadmap, enabling the company to scale with intention while staying grounded in the craft.

“We’re thrilled to have Markus join the CreamTeam,” said Tama Berkeljon, CEO of Creamsource. “We’re fully aligned on where the company needs to go and how best to support our customers in a changing market. His depth of knowledge and experience strengthens the whole organization and allows me to focus even more on the vision and R&D work that shapes our future.”

“I’m very excited to welcome Markus to the team,” added Sasha Marks, Creamsource CTO. “He brings a tremendous amount of industry and leadership experience, and with him in the hot seat, I’ll be able to dive even further into R&D and new product innovation alongside Tama. After more than twenty successful years, I’m looking forward to this next stage of Creamsource’s evolution.”

“After knowing Tama and Sasha for more than a decade, it’s a great opportunity to finally work together on the same team,” said Markus Zeiler, Group Managing Director. “Creamsource has a strong brand, great products, and an outstanding team spirit. I’m excited to help support their vision and to help shape what comes next.”
