Harbour Collective

What Harbour Collective does

Harbour Collective Ltd is a UK-based private holding company that owns and operates a network of twelve independent specialist marketing agencies under a shared-ownership model. The company was founded around two original agencies — Curious, a London-based creative services business, and Flourish, a Bristol-based specialist CRM agency — and has since expanded to twelve member agencies covering creative production, CRM, media planning and buying, brand strategy, sales activation, consumer PR, B2B marketing, customer data transformation, publisher content, digital experiences, and performance marketing. All shareholders are active in the business, which the company states preserves decision-making speed and individual agency management autonomy while enabling collective coordination.

The collective collectively employs 530+ specialists and serves enterprise clients across a diverse set of industries, with named clients including BT, John Lewis, Google Fitbit, Costa, Heineken, The Gym Group, Match, Bestinvest, and Soldo. Services span data and insight, media, content creation, engagement, experience, and production, marketed to enterprise marketing buyers seeking the scale of a group combined with the specialism of independent agencies. The go-to-market is sales-led and direct, with each member agency maintaining its own brand and client relationships while the holding coordinates cross-agency engagement.

The business model is professional services with quote-based, project-specific pricing on undisclosed terms; no revenue, pricing tiers, or recurring retainer structure are publicly disclosed. The company has stated an intention to acquire additional agencies in four target service areas — Customer Acquisition & Optimisation, Social & PR, Content, and Customer Experience — to round out the integrated marketing stack. There is no disclosed proprietary technology platform, AI capability, or external institutional funding.
