Prefer to run campaigns in-house? Compare influencer marketing platforms →
Shortlist agencies that have case studies in your industry and on the networks your customers use, ask who owns creator relationships and content rights, and compare how each one reports results (sales, reach, or content produced).
An agency runs campaigns for you, from creator sourcing to reporting, and suits brands without an in-house team. A platform is software your own team uses to find creators and manage campaigns, usually at a lower monthly cost.
