Top 11 Influencer Marketing Agencies

Ogilvy is a New York network agency founded in 1948 and part of WPP, with offices in most markets an advertiser can buy in.

What it sells is the idea, and the network to put that idea into every market on the same day. The awards record and the client list reach across every category, so the senior people on a brief have usually run a campaign at that size before. This is the shape of partner for a launch where the idea carries the risk and the budget is large enough to make the idea happen.

Ogilvy publishes 77 cases, and 20 of them carry a figure. Dove's #TurnYourBack reports 54m video views, 567K+ engagements and 174 pieces of press coverage. CeraVe's Super Bowl work reports a 25% sales increase and 32B earned impressions. Vaseline Originals reports a 466% launch sales uplift and two sold-out drops.

Best for brand-platform work that has to run in every market at once.

Edelman is a New York communications firm founded in 1952, and earned media is what it sells.

A creator programme here sits inside a wider communications engagement, with strategy, press and social planned together, so what a brand buys is a whole campaign rather than a booked roster. The unit is earned attention, counted the way a communications firm counts it: coverage, impressions, sentiment and stated intent. Brief it that way and the shape fits.

The published figures follow that unit. ASICS Eternal Run reports 1.7B earned reach and 81% purchase intent. Dove's Code my Crown reports 1.8B impressions and a 32% brand loyalty increase. Heineken's The Social Swap reports 122K engagements against 226M paid social impressions, and it separates the two. Go MonGolia is the outlier that names money: $1.2B in tourism revenue and 650K tourists.

Best for a campaign that has to earn press coverage, not just views.

Dentsu Creative is the creative arm of the dentsu network, launched in 2022 and run out of London.

Media, data and creative sit under one roof, so a creator programme is planned next to the rest of the buy rather than bolted onto it. The work also runs wider than creator marketing: loyalty programmes, pharma targeting, retail media and brand films sit next to the social campaigns, which is why the cases read as campaigns with a media plan behind them.

It publishes 30 cases and every one of them reports a result, which is rarer on this page than it sounds. Nutter Butter reports 3.3B earned impressions and 1.1M new followers off a run of deliberately strange TikToks. Crayola's Campaign For Creativity reports 4.1M TikTok impressions and $186K in earned media value. Foot Locker's The Hunt for Court People reports 169M impressions and a product that sold out in under two hours. Intel's Project Athena reports 370M impressions, and it says plainly that they are paid media.

Best for a brief that needs paid, owned and creator activity moving together.

YKONE is a Paris agency founded in 2008, working almost entirely in luxury, beauty and destination marketing.

Nearly everything it publishes is aspirational category work reported on reach, impressions and earned media value, which is the currency its clients buy in. Large creator rosters post across Instagram, TikTok and YouTube in the same moment, and the same houses buy always-on social management alongside the campaign bursts. The client list is the point: BOSS, Balenciaga, Guerlain, Piaget, Swarovski, Puma, MINI and several tourism boards.

It publishes 54 cases, 52 of them with numbers. BOSS's 2025 activations report 62.6M reach and 115.6M impressions. Experience Abu Dhabi's Formula One work reports 88M reach and 625M impressions. A handful go further and publish a return: MINI at 7.7x, MSC Cruises at 6.1x ROAS, reMarkable at 5.5x and Swarovski at 3.7x ROAS.

Best for a brand whose objective is to be seen as desirable by a whole country at once.

Billion Dollar Boy is a creator agency founded in 2014, working from London and New York, mostly in beauty, drinks, fashion and retail.

The lane is clear and the agency stays in it, running at speed and at volume with the delivery table printed under each case. Ray-Ban Stories publishes both sides of the reach question, 29M potential reach and 1.8M impressions delivered, under the same heading. A brand in one of those categories is briefing a team that has already shipped the same shape of campaign.

It publishes 37 cases and every one of them carries a figure. Zalando, Garnier, Heineken, PepsiCo, Primark, Loewe and L'Oréal Paris are all on the record. Lipton Ice Tea's Pass the Sunshine reports a 15% sales increase against 40M impressions and a £1.93 CPM. Walkers reports an 11.2% ad recall lift and 125M impressions. Vichy reports a 99% sell-out on Mineral 89.

Best for beauty, drinks and fashion campaigns that need scale fast.

Open Influence is a Los Angeles agency founded in 2013, deepest in automotive, entertainment and travel.

Its reporting habit is unusual and useful. A client agrees the target up front and gets the delivery measured against it in the same document afterwards, so you see the size of the beat rather than only the size of the number, and each campaign stays readable against the last.

It publishes 26 cases, 25 of them carrying figures. The Disney Pixar Lightyear campaign reports impressions at 709% of goal and engagement rate at 149% of goal. Visit Philadelphia reports 627% of its impressions goal and 440% of engagements. Mercedes-Benz reports reel view rate at 132% of benchmark and 95.4% positive comment sentiment. Subaru, adidas Originals, Uber and Moderna all appear with view and engagement totals attached.

Best for a brand that wants the plan and the delivery side by side.

Buttermilk is a London agency founded in 2016, working in beauty, fashion and wellness.

Every case comes back as the KPI and the delivery against it, which is how a brand running creator activity month after month keeps each campaign readable against the last. The team is small enough that the people who pitch a programme are the people who run it.

It publishes 13 cases, all with figures, and the client list is the reason it is here: Prada Beauty, Armani Beauty, Estée Lauder, Marc Jacobs, Mugler, Nike, Gap and Elizabeth Arden. Prada Beauty's US launch reports views at 684% over KPI, engagement at 141% over, and a number one Sephora ranking in two categories. Mugler reports views 262% over KPI. Gap reports 6% year-on-year sales growth and a 198% rise in brand mentions. Nike's Chase the High reports 13M impressions, 7.5% engagement and a 450% spike in product search.

Best for beauty and fashion brands running creator programmes at volume.

We Are Social is a global social agency founded in 2008 and run out of London, with offices across Europe, the Americas and Asia.

The work is genuinely inventive: hashtag mechanics, in-game formats, stunts built for a platform rather than adapted to one. That is what a launch which has to be talked about is buying, and the mechanics behind the biggest numbers here were designed for the feed they ran in.

#PlayWithPringles reports 4.7B views and 2M videos created. adidas's Super Bowl piece reports 97M Instagram views. Pepsi's Champions League opening ceremony reports 250M video views. Barilla's The Rooftop Match reports 3.6B reach across 240 outlets. Brand measures show up where the client tracked them: Lavazza reports a 4.1% purchase intent increase and McCain a 9% purchase rise among younger buyers.

Best for a campaign that has to be talked about, in one market or across the offices it runs worldwide.

Socially Powerful is a London agency founded in 2017, built around short-form video, with teams sitting in the markets being sold into rather than servicing them from London.

The reporting includes clicks, which is rarer here than it should be, and short-form video is the unit throughout. A TikTok-first brief that has to work across several countries is run from inside each one.

It publishes 16 cases, all with figures, most of them TikTok, and the client list runs from Ulta Beauty and L'Oréal to Lenovo Legion, PUBG Mobile and TikTok itself. The Gym Group campaign reports 15M views and 1M clicks. Xiaomi reports 20M views and 250K clicks. PUBG's anniversary reports 12M reach and 120K+ clicks. The Body Shop's Middle East work reports 17M reach, 30M impressions and a 15% uplift in sales.

Best for TikTok-first campaigns in beauty, gaming and consumer technology.

Viral Nation is a Toronto agency founded in 2014 that grew out of gaming and creator management.

It sells creator campaigns, social commerce and its own measurement products under one contract, which is why the cases are unusually specific about what happened rather than stopping at views. Gaming, esports and creator commerce is the centre of it.

It publishes nine cases. The e.l.f. Cosmetics campaign, where a creator ran the company for a day, reports 18.9M views in 24 hours, $857K in earned media value, 50K units sold in ten hours and the number one TikTok Shop ranking in the US. The Call of Duty League work reports 96M impressions and subscriber growth of 32% year on year. ViewSonic reports 10.1M impressions, 76K clicks and a 2.5% click-through rate.

Best for gaming, esports and creator-commerce brands buying campaign and commerce from one partner.
