What Zealot UK does
Zealot is a privately held audiovisual advertising agency that creates trailers, TV spots, digital campaigns, and design assets for film and TV productions. Its integrated service offering spans trailer production, finishing services (audio mixing, conform, colour grading, supervision, and asset distribution across theatrical, broadcast, internet, radio, and out-of-home formats), digital and social campaigns, key art, print materials, and title sequences — supported by a ZUK GFX sub-brand for design and motion-graphics work. The firm is headquartered in London with additional offices in New York and Los Angeles, and it operates separate UK and US legal entities (Zealot UK and Zealot Inc.).
The company's client base is anchored by major entertainment buyers including Netflix (UK and Germany), Disney+, Warner Bros. Discovery, Paramount+, and Lionsgate, alongside a broader roster of independent production companies, distributors, and branded-content clients such as Fremantle, Kudos, Picturehouse, Curzon, Well Go USA, Black Bear Pictures, Red Bull Studios, and Embankment Films. Work is acquired through direct enterprise relationships and industry reputation rather than via product-led or self-serve channels.
Zealot earns revenue through project-based professional services fees for trailer, finishing, and campaign deliverables, with quote-based pricing that is not publicly disclosed. The firm has no disclosed funding rounds, no public listing, and no parent company; ownership commentary suggests a founder-operated, independent structure. Industry recognition includes the GEMA Award for Agency of the Year (2026) and Golden Trailers nominations, supporting its positioning as a specialist mid-sized player in the entertainment-advertising value chain.
