KASTNER LONDON LIMITED

What KASTNER LONDON LIMITED does

Kastner London Limited is an independent, London-based creative advertising agency founded in 2001, operating as part of a wider international Kastner network of 8 offices across Europe and the United States with stated reach into 108 markets. The firm serves brand builders and marketing leaders primarily in the UK Food & Beverage vertical, with a 36+ year continuous agency-of-record relationship with Red Bull as its signature anchor client and additional engagements including Blood Monkey (spirits) and Brixton Motorcycles.

The agency's core product is the registered Pola*riser® methodology — a brand-strategy framework operationalised through the Pola*riser® Workshop (a paid strategic engagement), the Pola*riser® Index (an annual GWI-partnered research study covering 2,000 UK consumers and 100 F&B brands), and the Pola*riser® Principles (a published strategic framework), plus the more recent Bitesize Breakdown checklist. Full-service delivery spans branding (strategy, positioning, identity, design, packaging) and advertising (campaigns, digital, social, film, photography, illustration, motion graphics). No AI/ML, API, or software-product components are disclosed; the technology layer is methodology and research-based rather than code-based.

Kastner London generates revenue through project-based professional services fees for creative and brand-strategy work; pricing is not publicly disclosed and is handled through direct, consultative outreach to senior team members. Go-to-market combines direct enterprise sales targeting F&B CMOs with thought-leadership demand generation via the annual Pola*riser® Report, blog content, and Eventbrite-promoted webinar/panel events, supported by LinkedIn and Instagram organic presence. The firm is independently owned with no disclosed external investment, parent company, or institutional backers.
