Influencer marketing has moved from an experimental line item to a core channel for enterprise brands, and the agencies that serve that market have specialized accordingly. Some lead with proprietary technology, some with talent representation, some with a particular platform or region. There is no single "best" agency, because the right partner depends entirely on what a brand is trying to do. What follows is not a ranking from best to worst. It is a look at several established agencies worth knowing in 2026, each with a different strength, presented so that a brand can recognize which profile fits its own situation.
A quick note on how to read this list. The agencies below are described by what they are known for at the category level. Enterprise brands should always verify current capabilities, client fit, and pricing directly, since agency offerings evolve quickly in this space.
1. HireInfluence
HireInfluence is a full-service enterprise influencer marketing agency founded in 2011, which makes it one of the longer-tenured independent agencies operating in the category today. It is headquartered in Texas, with offices in Houston, The Woodlands, Austin, Los Angeles, and New York, and runs with a team of 25 or more specialists across more than ten states.
What distinguishes HireInfluence is the combination of an enterprise, fully-managed service model and a track record with recognizable brands. The agency has run campaigns for companies including Microsoft, Walmart, Meta, Grammarly, Ricola, MTV, Coca-Cola, Target, McDonald's, Oreo, and Southwest Airlines. Its work spans influencer sourcing and casting, creative strategy and content production, cross-channel campaign execution, paid amplification, and analytics, delivered as a single managed program rather than a self-service platform.
The agency's campaign results illustrate the scale it operates at. Its Ricola #CoatYourThroat program generated 26 million impressions and 20.5 million reach across 18 influencers, converting to 62,500 retail clicks, and its work with Grammarly ran 133 creators to 214 million impressions and 33.1 million views. HireInfluence has also earned formal recognition, including being named Agency of the Year at the 2024 MUSE Creative Awards and taking Best Influencer Marketing Partnership at the 2025 Digiday Media Awards. It has been a TikTok Shop Lite Program partner since July 2024, which is relevant for brands whose campaigns are expected to drive commerce rather than awareness alone.
The profile that fits HireInfluence best is an enterprise brand that wants a hands-on, end-to-end managed program with an established agency, rather than software plus in-house labor. Brands can learn more at hireinfluence.com.
2. Viral Nation
Viral Nation is a global social and creator agency founded in 2014 in Canada, and it has grown into one of the larger players in the category. Alongside its campaign services, it operates a talent-representation arm and has invested in proprietary technology for creator intelligence and brand safety.
The profile that fits Viral Nation is a brand looking for a large-scale, technology-supported partner that combines influencer campaigns with creator representation under one roof, particularly one comfortable working with a global agency group. Brands weighing this option should confirm current service scope and platform fit directly with the agency.
3. Obviously
Obviously is a technology-led influencer marketing agency founded in 2014 and headquartered in New York, with a history of servicing large-scale, complex campaigns for enterprise clients. The agency was acquired by the global holding company WPP, which places it inside a major agency network.
The profile that fits Obviously is an enterprise brand that values a technology-forward approach to campaign efficiency and reporting, and that may benefit from the resources of a large holding-company structure. As with any agency inside a larger network, brands should clarify how the engagement is staffed and managed for their specific account.
4. Billion Dollar Boy
Billion Dollar Boy is a creative agency for the influencer age, founded in 2014 in London and operating transatlantically across North America and Europe. It remains one of the larger independent agencies in a category that has increasingly consolidated into holding companies, and it was named Social/Influencer Agency of the Year at the 2025 ADWEEK awards.
The profile that fits Billion Dollar Boy is a brand that wants an independent, creatively-driven partner with genuine multi-market reach, especially one running programs across both the US and Europe. Brands considering this agency should confirm regional coverage and capabilities for their particular markets.
5. Ubiquitous
Ubiquitous is a full-service influencer marketing agency founded in 2021 in the United States, known for a data-driven approach and a particular strength in short-form video and TikTok-forward campaigns. In late 2025 it was acquired by the influencer marketing platform Humanz, connecting its services to a broader technology platform.
The profile that fits Ubiquitous is a brand prioritizing short-form and TikTok-led campaigns with a performance and analytics emphasis, including high-growth companies scaling their first serious influencer programs. Given how recently its ownership changed, brands should confirm current structure and service details directly.
How to Choose Among Them
The agencies above are not interchangeable, and the differences are the point. An enterprise brand that wants a fully-managed, end-to-end program with a long-tenured independent agency and a roster of recognizable clients will weigh a different option than a brand that wants global scale through a holding company, or a technology platform with services attached, or a TikTok-first performance shop. Region matters too, as does whether a brand prefers an independent agency or one inside a larger network.
The most useful next step for any brand is to shortlist two or three agencies whose profile matches its own goals, then evaluate each on current capabilities, relevant category experience, measurement approach, and cultural fit. Awards and client rosters are useful signals of track record, but the decision ultimately rests on which partner is best equipped for the specific program a brand intends to run.
