Best influencer marketing agencies in Spain 2026

Because Spanish agencies more often publish a legal notice with an address, which is what the directory requires to mark a head office, and that is why 35 profiles have a declared base in Spain. That reflects what each website declares, and not market size or agency quality.

4 of the 35 agencies based in Spain name at least one Latin American country among their markets, and they also appear on that country's page in the "Operating in" block. The rest do not declare it on their website, which does not mean they do not do it.

Only the generic address the agency publishes on its website (hello@, info@, contacto@) is used, never named individuals, and in the email we say who is responsible, where the address came from, what it is used for and how to opt out. Opting out of contact is applied within 48 hours and recorded so the agency is not written to again. The profile, built from public data on the agency's own website, stays listed unless the agency also asks for removal.

An agency provides influencer marketing services to brands. A software is a SaaS tool with no agency service, and a platform is a creator marketplace. They go in separate blocks, "Software and platforms", because they are not hired the same way or compared on the same fields; an agency that also has its own software is listed as an agency.

The directory does not know: it publishes the figure as the agency writes it on its website, and almost none clarifies taxes, scope or usage rights. That is why the footnote of every table says the minimum is not a quote and that those points are confirmed with each agency.
