Yes, we ranked ourselves first on this list of London influencer marketing agencies. Here’s the evidence: 300% sales uplift and 7 consecutive sell-outs for Rimmel London‘s Wonder’Ink campaign, driven by 30 creators who generated 18M+ impressions across TikTok, Instagram, and YouTube. That kind of performance doesn’t happen by accident.

Our approach to influencer marketing starts with understanding that influence flows through native content, not polished advertisements. When Your Parking Space needed to drive app downloads, we delivered 36K+ installs and a 57% revenue surge by matching creators to audiences based on behavioral data, not follower counts. The result was 19M+ impressions and 210K+ clicks from creators who understood the product’s value proposition.

Our co-founder Inigo Rivero helped build TikTok’s European operations before launching House of Marketers, which means we’ve been inside the platform’s evolution from the beginning. That institutional knowledge translates into campaigns like Tim Hortons‘ coffee culture push across Canada, where 31 creators delivered 807K views and 5.17% TikTok engagement rates. HoM operate as a global team of 75 specialists across Europe, North America, Asia, Africa, South America, and the Middle East, giving brands authentic local insight at international scale.

8.9x ROAS and $395K in added monthly revenue is what Selfie Leslie achieved through strategic influencer partnerships, and it highlights how precision targeting outperforms broad reach campaigns.

Premium brands like Adidas, MAC Cosmetics, Maybelline, and L’Oreal rely on Komodo’s end-to-end campaign management, from initial influencer discovery and vetting through to content creation and performance reporting. The agency consistently exceeds engagement benchmarks by combining data-driven insights with creative strategy across TikTok, Instagram, and other social platforms.

150+ creators across London and New York is the team size that lets Coolr operate as cultural architects rather than traditional agency executives, and it shows in campaigns that become genuine cultural moments. Their approach treats creators as storytellers embedded at the heart of social strategy, not media placements you buy and forget.

As an official TikTok Marketing Partner, Coolr brings deep platform expertise to creator partnerships that feel native rather than forced. Their standout Tango collaboration with TikTok grime icon Millie B created the ‘Tango Blast’ rap, a co-created cultural moment that sold out the limited-edition product nationwide and became Tango’s top-performing TikTok launch.
