What does an influencer marketing agency actually do?

An influencer marketing agency builds, runs and measures creator-led campaigns end-to-end: strategy and brief, creator selection and negotiation, content production and approvals, paid amplification of the best-performing organic posts, and reporting against commercial KPIs. At OOB, we treat creators as part of the creative team, not a media line item — they sit on briefs alongside our strategists and editors.

How do you choose the right creators for a brand?

We start from the brief, not from a media kit. Audience-authenticity scoring, brand-fit psychographics, commercial performance history (CPMs and ROAS from past partnerships), platform specificity (someone who is great on TikTok is often weak on YouTube) and content quality. We don't chase follower counts — a 30k creator who shifts product beats a 1m creator who doesn't.

How much does influencer marketing cost?

Creator fees scale wildly: micro-influencers (10-100k followers) £500-3,000 per post; mid-tier (100k-500k) £3,000-15,000; macro (500k-1m) £15,000-50,000; celebrity-tier creators are bespoke. OOB's management fee is typically £5-15k per campaign depending on creator count and content volume. We're transparent about what's a creator fee vs an agency fee — no hidden mark-ups on talent.

Whitelisting, paid amplification, branded content ads — what do you handle?

All of it. We negotiate creator content rights upfront so the best-performing organic post can be amplified with paid spend through the creator's account (whitelisting / Spark Ads on TikTok, partnership ads on Meta). Branded content tag setup, FTC/ASA compliance disclosure, and the paid media buying itself — handled by the same team that picked the creator.

Can you run campaigns globally or are you UK-only?

Global. We have shipped creator campaigns in 14 countries this year alone — UK, US, France, Germany, Spain, MENA region, APAC. We operate in-house in London, with vetted creator-vetting partners in the major creator markets. Multi-market rollouts are coordinated by one OOB lead so the brief stays consistent.

How do you measure influencer ROI?

Every campaign gets a commercial KPI before kick-off: CAC, ROAS on amplified spend, qualified pipeline (B2B), branded search lift, organic lift on owned channels. We measure incremental lift wherever possible — comparing matched markets or matched audiences with and without creator exposure. Creator content that gets paid amplification is reported on platform-level ROAS exactly like any other paid social asset.

How long does an influencer campaign take to launch?

Strategy and shortlisting: 2-3 weeks from brief. Creator outreach and negotiation: 2-4 weeks. Content production: 2-6 weeks depending on creator count and complexity. So expect 6-12 weeks from brief to first content live. Always-on creator programs (rolling cohorts) compress this once the partnerships are in place.

What size brands do you work with?

Founder-led startups raising Series A through to FTSE 250 brands. We've shipped creator campaigns for ARTAH (wellness), Indomie UK (food), Knickerbox (fashion), Sonos (consumer tech) and dozens more. We don't pre-package fixed creator bundles — every campaign is scoped on the brief.

How is OOB different from other influencer marketing agencies?

Three things. (1) Our creators sit on the creative team — they brief in alongside strategists and editors instead of getting a deck dropped on them. (2) We have an in-house creator network (the OOB Creator Collective) of vetted creators we work with repeatedly, not a database we paste-and-match from. (3) We measure incrementality, not just GRPs — and if the campaign isn't shifting product, we'll tell you before you ask.
