Best Sports and Fitness Influencer Marketing Agencies in 2026 (19 Compared)

A sports influencer agency pairs brands with athletes and sports creators for sponsored content, and a fitness influencer agency does the same with trainers, gym creators and runners. This guide compares 19 of them, 11 on the sports side and 8 on the fitness side, using what each says on its own website, read on 5 November 2026.

Three findings shape it. Most agencies that top these lists show no sports or fitness work on their own sites. Almost none publishes how it handles athlete image rights or supplement claims. And only OpenSponsorship and Twirl publish a price. Every result an agency quotes is its own claim, and none were audited.

Sports and Fitness Influencer Agencies at a Glance (Quick Comparison)

Nineteen sports and fitness influencer agencies compared on focus, evidence, published fee and rights or claims terms (own sites, read 5 November 2026)

Two agencies publish a fee, and none publishes terms for athlete image rights, league conflicts or supplement claims. The table says not stated where a site shows none.

How We Ranked These Sports and Fitness Influencer Agencies

We read each agency’s own site for a sports, athlete or fitness page, named client work, published fees and any statement on rights or claims. Within each group, agencies with the most checkable evidence come first, and talent-side and local firms come after, because their clients are athletes rather than brands.

We left out Viral Nation, whose site has no sports or fitness page, Ubiquitous for sports, Socially Powerful for sports because its one sports case ran through meme pages with no athletes, The Influencer Marketing Factory, whose site could not be read, and Hypefactory, which names no sports client. Many ranked lists on these topics are written by agencies that put themselves first, so use ours to build a shortlist.

11 Best Sports Influencer Marketing Agencies and Athlete Platforms in 2026

1. OpenSponsorship: Best for a Published Price and a Large Athlete Network

OpenSponsorship describes a done-for-you sports influencer service covering matching, outreach, contracts and reporting. It names Travis Kelce, Trae Young, Jon Jones and Kyle Walker as examples of its network and claims 25,000+ athletes, creators and teams across 150+ sports. It is the only sports option here that publishes fees: Full-Service at $2,000 a month and Elite at $5,000 a month, with athlete fees on top. It says its team negotiates with athletes and agents but states nothing on usage rights, disclosure or league conflicts. Its comparison with traditional agencies has no data behind it.

2. Opendorse: Best Platform for College Athlete NIL Deals

Opendorse, based in Lincoln, Nebraska and launched in 2012, is an NIL marketplace and technology platform, not an agency. Brands can use it self-serve or managed, and it claims 200,000+ athletes, most of them in college, and 1,000+ brands. It says its tools include compliance and rights management but publishes no terms and no fees. Its newest post when we read it was dated 29 October 2026.

3. NeoReach: Best for Large Budgets and Sports Betting Brands

NeoReach has a dedicated sports page offering full-service campaigns, athlete partnerships and sportsbook and fantasy acquisition, with cases for DraftKings, FanDuel and FIFA. Its sports work is dominated by betting, which carries gambling-compliance limits, and it states a $100,000 minimum engagement while its pricing page also says full-service campaigns start from $25,000. Its FIFA case describes both a 2022 World Cup and a Club World Cup, so read it carefully. It says nothing on NIL or athlete image rights.

4. Disrupt Marketing: Best for UK Sports Bodies

Disrupt Marketing, at 77 Hatton Garden in London, has a sports influencer marketing sector page covering creator and athlete partnerships, live sport and in-person activations. Its sports clients include the FA, England Rugby and the ECB, with a claimed 2M+ impressions on the ECB Women’s T20 World Cup campaign. It names no athletes, most of its case studies are non-sport and its posts carry no dates.

5. Distinction Agency: Best for a Small Athlete and Creator Roster

Distinction lists athlete and influencer marketing, brand partnerships, experiential and PR, and shows 17 talent including nine athletes. It mentions whitelisting under talent representation and published a piece on NIL in October. It names no client case studies, no fees and no rights process.

6. Extreme International: Best for Action and Adventure Sports

Extreme International runs creator campaigns, athlete management and live activations for action sports, adventure, outdoor and motorsport brands, with a roster page of 17 athletes. Its case studies are mostly from 2016 to 2019 and several URLs do not match their titles. It says usage requirements are agreed in the plan but gives no detail.

7. Athelo Group: Best for CrossFit, Strength and Mid-Tier Athlete Ambassadors

Athelo Group is a talent agency that spans sports and fitness. It manages athletes and sports influencers, with separate roster pages and named talent such as Dani Speegle and Conor Daly, and a dedicated page for elite CrossFit, functional fitness, strength and bodybuilding athletes. It names three partnership models, Elevated Partnership, Recruitment Model and Content x Distribution, and lists brand partners including Dymatize, NOW Foods, BUILT Bar and Liquid I.V. It publishes no fees, rights terms or campaign metrics, many of its 26 listed case studies are 2021 uploads and only titles and images were readable. It works on the athlete side, so it is closer to a talent agency than a brand-side agency.

8. Octagon: Best for Global Brands Buying Talent and Rights

Octagon has a large sports practice with talent pages by sport, a claimed 900+ talent and 1,000+ staff, and work for brands such as BMW, M&S and Mastercard, including an M&S campaign at the 2026 British Grand Prix. It is a representation and rights agency rather than an influencer platform, creator-led activation is not described, NIL appears as a single word and no pricing is published.

9. THE·TEAM: Best for Elite Athletes and Big Events

THE·TEAM (the.team) lists sports talent by sport, including football from NIL to the NFL, an IP licensing division and a Rexona x FIFA World Cup 2026 case study with 1,000+ creators. Its pages do not state a rebrand from Wasserman, which we inferred from redirects, and the similarly named the-team.com is an unrelated parked domain. No pricing or rights policy is published.

10. Slice Sports Management: Best for College and High School NIL

Slice manages NIL marketing deals and personal branding for high school and college athletes, and says legal, financial and tax work is handled in-house. It is run from New York and works on the athlete side, not for brands. Its homepage claims 1,000+ deals while its about page says 350+, it contains placeholder text and it does not describe NIL compliance, so treat the claims with care.

11. Athletes Endorse: Best for Local Businesses and College Athletes

Athletes Endorse, a one-person firm focused on Southern California, matches local businesses with local college athletes and says it gets each athlete’s university approval and does not sign anyone until you approve the budget and athlete. It publishes no fees and no case studies with numbers, so it fits a small local campaign, not a national one.

8 Best Fitness Influencer Agencies for Gyms, Apps and Supplement Brands

Here the question is less who the creator is and more what the creator says. Check each agency’s claims process before its roster. Athelo Group, above, also covers CrossFit and strength athletes.

1. BibRave: Best for Running, Endurance and Race Marketing

BibRave grew out of an online runner community in late 2013 and now markets fitness and outdoor brands through influencer programs, ambassador programs and race marketing built on micro-influencers. It names New Balance, Strava, Nuun, Brooks Running, NOBULL, Garmin and Zwift among 13 clients, which is the most fitness-specific roster in this guide, and its race influencer network asks for 1,000+ followers. It publishes no fees, no case study figures and no claims or disclosure language, and its focus is runners and endurance rather than strength or supplement work.

2. The PHA Group: Best for UK Fitness PR and Influencers Together

The PHA Group is a PR-led agency with offices in London, Manchester, Leeds, New York and Boston, and a fitness sector page with a long client list including Therabody, TRX, Echelon Fitness, Spartan Race, Huel and PureGym. Influencer work runs from matchmaking to tracking across nano to celebrity tiers, gifted and paid, with reporting by link and code. It says HUUB quintupled a crowdfund target and that TRX became a TikTok community built from scratch. It names no influencer fees or claims process, and the influencer case studies it lists, such as Cano Water and Cuisinart, are not fitness brands.

3. The Influence Agency: Best for Vitamin and Supplement Brands

The Influence Agency, a Toronto full-service agency founded in 2017 with 69 in-house specialists, has a sector page for supplement brands, group fitness studios and mindfulness brands, and clients including Jamieson Vitamins, Youtheory and Iovate. Its Youtheory Canada launch used 30+ creators and 207 pieces of content and reports 136M+ impressions and 27.9M Canadians reached, which are impressions, not sales. Influencer work is one service among SEO, web and paid, fees are quote only, no claims process is stated and one case study link points nowhere.

4. House of Marketers: Best for Fitness Apps and Subscriptions

House of Marketers, in London, treats fitness as an app and subscription practice: creator ad assets and paid social aimed at sign-ups, with the sign-up event agreed before launch and paying subscribers reported first. Its Daily Burn case claims 30M+ impressions, 300K+ clicks and 7,500+ paying subscribers, published 19 April 2024 and updated 6 March 2026. The cost per acquisition field on that page is an empty placeholder, it has only two fitness-adjacent cases and it states no fees or claims process.

5. inBeat: Best for Supplement Briefs With Legal Review

inBeat has no fitness page, but it publishes the most detailed review process in this guide. Its legal team has the final say, posts are checked against FTC guidance, creator credentials are verified and disclosure sits inside the video. A supplement post dated 7 October 2026 describes counsel-signed approved and banned language, a two-person review of scripts and final cuts and payment tied to passing review. Fitness appears as a creator type and a logo list, its one nutrition case, Soylent, is undated and fees are not published.

6. Ubiquitous: Best for Supplement Creator Campaigns

Ubiquitous (ubiquitousinfluence.com) has no fitness vertical, but it has dated supplement and health cases with numbers: Bloom Nutrition in February 2023, Hers in June 2022 and BlueChew in August 2024, where 14 creators and 20 videos in a 30-day $75K test delivered 10.42M views before a three-month renewal. The BlueChew case also explains restricted words and structure-function statements that had to be avoided, with two videos taken down and one restored. It publishes no fees, no fitness-brand case and no review process of its own, and its headline view counts do not always match the body text.

7. Socially Powerful: Best for a Large Gym Brand Campaign

Socially Powerful, with offices in London, New York, Dubai and Beijing, has a fitness industry page and one named fitness case, a TikTok campaign for The Gym Group in the UK that seeded 500+ nano creators plus a TikTok TopView ad. The results section says 15M views, 1M clicks and 500K engagements, while the strategy section says over 59M views, so we quote the first. It publishes no fees, the case is undated and it says it serves supplement companies without showing a supplement case.

8. Twirl: Best for Fitness UGC With Published Prices

Twirl, in London, is a UGC production service and creator network rather than an influencer program agency, and the only fitness option here with a full price list: pay as you go from GBP 240 per video with a four-video minimum, managed campaigns from GBP 1,920 and monthly plans from GBP 400 plus video costs. It says credits never expire, includes two revision rounds and grants an unlimited paid and organic usage licence with no duration or territory stated. It names no gym or supplement case, its creator network claim ranges from 4,000 to 8,000+ across pages and its credit-pack calculator is inconsistent, so we do not quote credit-pack prices.

Fitness Instagram Agencies and Fitness TikTok Agencies: What to Ask For

Fitness brands often search by platform. On the pages we read, TikTok evidence is stronger: Socially Powerful’s Gym Group campaign and PHA Group’s TRX community are both TikTok-led, and Ubiquitous shows how TikTok wording rules shaped its supplement work. None of the eight showed an Instagram-specific fitness case with results, so ask for one, with the period and the baseline. For platform specialists, see our guides to TikTok influencer marketing agencies and YouTube influencer marketing agencies.

Fitness Influencer Agencies in the UK

UK-based options in this guide are The PHA Group (London, Manchester and Leeds), House of Marketers and Twirl in London, Disrupt Marketing for sports bodies, and Socially Powerful, which has a London office. For UK campaigns, follow the ASA’s labelling guidance and the CAP rules on food supplements and weight control described below.

Ainfluencer: Our Own Option, Not Ranked

Ainfluencer is our own product, so we do not rank it. It pairs a marketplace of 5M+ Instagram, TikTok and YouTube creators with a fully managed service: AI matching, deals and approvals in the platform and payouts held in escrow until content ships. Its creators include athletes, trainers and fitness creators across tiers. For a wider comparison, see our guide to the best influencer marketing agencies.

Sports and Fitness Influencer Marketing by Platform: Instagram, TikTok, YouTube and Twitch

Where sports and fitness creator content tends to work (our view, not platform data)

Athlete Influencer Marketplace vs Sports Influencer Agency

Platform or agency for athlete influencer marketing

Creator-Led Sports Activations vs Traditional Sponsorships

Two ways to put a brand into sport

Many brands use both. If your budget is small, creator-led work is the place to start, and our guide to micro influencer marketing agencies covers the smaller creators who do most of it.

Fitness UGC Ads and Ambassador Programs

Best Platform to Find Fitness Creators for UGC Ads

UGC for ads means paying creators for videos you run as your own ads. It needs usage rights, a clear brief and a way to test hooks. Twirl is the only agency here that publishes a per-video price. Ask any other agency or platform for the rate, the usage period, the number of revisions and who owns the raw files.

How to Run a Fitness Ambassador Program

An ambassador program gives a group of trainers, athletes or regular gym-goers a discount code, product and a brief, for a long-term relationship rather than a single post. It works best with smaller creators who train in front of their audiences, and the 1,000-follower entry bar BibRave sets for its race network is a useful reference point.

Athlete Image Rights, NIL and Disclosure: What Brands Must Clear

Image Rights and Usage Terms

An athlete’s name, image and likeness can be controlled by the athlete, an agent, a team, a league or a school, depending on the athlete and the deal. None of the agencies above publishes its approach. Put the answers in the contract: where you may reuse the content, for how long, in which media, whether you may run it as paid ads, and whether the athlete may work with competing brands. This is our advice, not a legal rule, so ask a lawyer for deals of any size.

College Athletes and NIL

The College Sports Commission’s NIL page says NCAA Division I athletes must report third-party NIL deals worth $600 or more in aggregate through its NIL Go portal within five business days, and that deals are reviewed for valid business purpose and a reasonable range of compensation. The duty to report falls on the athlete, and a deal that is not cleared can cost the athlete eligibility. As a brand, build the deal so the athlete can report it, and expect delays.

Disclosure for Paid Athlete and Fitness Posts

The FTC’s Endorsement Guides questions and answers say a material connection such as payment or free product should be disclosed clearly, usually near the start of the post and inside the video, and that vague terms such as gifted are often not enough. It also says advertisers and their agencies carry responsibility for their endorsers, so you need a program that tells creators what to say, checks posts and acts on problems. Pre-approving paid posts is the FTC’s suggestion.

In the UK, the ASA’s influencer guide, dated 23 October 2026, says any payment or incentive triggers disclosure, including free products, and that the influencer, the brand and any agents share responsibility for the label. It recommends labels such as #Ad at the very start of the content, advises against vague ones such as gifted or collab, and says disclosure should continue for 12 months after the relationship ends.

Team, League and Sponsor Conflicts

Athletes sit inside team, league or school sponsor deals, and some rules apply only during major events such as the Olympic Games. Check exclusivity and category conflicts in writing before you pitch, and ask the agency who clears them. No agency in this guide publishes how it handles this.

Supplement and Health-Claim Rules for Fitness Influencer Campaigns

Health and Supplement Claims in the US

The FTC’s Health Products Compliance Guidance covers supplements, foods and health devices, and says advertising includes social media and influencer marketing. Health benefit claims need competent and reliable scientific evidence before the ad runs, testimonials are not a substitute for science, and weight-loss claims need human trial evidence that measures weight change. It also says endorsers and intermediaries can be liable, so a brand cannot hand the risk to a creator or an agency. For brands in the pharmaceutical or medical categories, see our guide to healthcare influencer marketing agencies.

Weight Loss, Before-and-After Photos and Body Image

In the UK, CAP advice says a food or supplement that causes weight loss makes a health claim, so only claims authorised on the GB Nutrition and Health Claims Register are allowed, and claims about a rate or amount of weight loss are not permitted for foods or supplements. CAP treats before-and-after photos like testimonials, needing signed, dated proof and no implied rate or amount of loss. Put these limits in every creator brief. This is not legal advice, so ask a lawyer before a supplement campaign.

How Much Does a Sports or Fitness Influencer Marketing Agency Cost?

Athlete Fees, Agency Fees, Rights and Usage

• Athlete or creator fee. Negotiated per deal, and by far the largest line for well-known athletes.
• Agency fee. A retainer, a share of spend or a fee on payouts. OpenSponsorship publishes $2,000 and $5,000 a month, and Twirl publishes UGC from GBP 240 a video.
• Paid media. Always paid to the platform on top of any agency fee.
• Usage rights and exclusivity. Wider reuse and category exclusivity raise the price.
• Product and travel. Gifting, shipping and event costs are often not in the quote.

How sports and fitness influencer agencies usually charge

How to Find a Sports Marketing Agency That Fits Your Budget

Start from what you can spend on athletes, then work backwards. A small budget fits a marketplace or a micro and nano creator program, and a large one fits a full-service agency with a minimum, such as NeoReach’s $100,000. Ask for a written quote that separates the three money lines above, and read our guide to influencer marketing agency pricing for how agency fees are built.

What a Sports or Fitness Influencer Campaign Looks Like in the First 90 Days

Month One: Brief, Claims and Shortlist

Agree the goal, the budget and the sports or training calendar. Write the approved claims and the no-go list, then shortlist creators and check conflicts and image rights before any pitch.

Month Two: Content and Activation

Run the first content and any activation or ambassador codes, with approvals, disclosure and claims checked on every paid post.

Month Three: Read Results and Renew

Compare each creator’s sales and engagement, keep the ones that worked and re-brief. Sports seasons and fitness peaks such as January move fast, so plan renewals around them.

How to Measure Athlete and Fitness Influencer Marketing: 4 Numbers to Track

• Tracked sales per creator. Codes and links, with discounts netted out.
• Engagement against the creator’s own size band. Not against a global average.
• Audience fit. Whether the followers are in the markets and age groups you sell to.
• Cost per result. Fee plus product plus media divided by sales or sign-ups.

Turning Tournament and Fan Engagement Into Sales

Big events bring attention, but attention is not sales. Give each athlete a code or link, post before and after the event as well as during it, and ask the agency to show a case where a fan action, such as a code use or a sign-up, was counted.

When Should You Hire a Sports or Fitness Influencer Marketing Agency?

Hire one when you want several creators at once, deals need negotiation and clearances, or you lack the time to manage approvals. Try a marketplace or an in-house test with two or three creators first if your budget is small. If you would rather pay for sales than for posts, see our guide to sports affiliate marketing agencies.

In-House vs Marketplace vs Influencer Agency

Three routes to sports and fitness influencer marketing

Endurance and Niche Sports Brand Partnerships

For running, cycling, triathlon and other endurance sports, the audience is smaller and more loyal, and micro creators and ambassadors often outperform big names. BibRave is built for this.

How to Choose the Right Sports or Fitness Influencer Marketing Agency

• Real evidence in your category. A sports or fitness page and named work, not one line in a service list.
• A rights and claims process. Ask who clears image rights and league conflicts, and who checks supplement and health claims.
• Creator access. Which athletes or creators it can actually reach, and whether through agents.
• Reporting that counts sales. Not only reach and likes.
• Clear fees. Creator, agency and media lines separated in writing.

Red Flags When Hiring a Sports or Fitness Influencer Agency

• A list of famous athletes or fitness names with no evidence it has worked with them.
• Reach figures with no definition of what they count.
• No answer on image rights, usage terms, disclosure or supplement claims.
• Before-and-after results promised or shown without proof.
• A guaranteed sales or engagement result.
• Case studies from years ago, or from other categories, shown as proof.

Questions to Ask Before You Sign

• Who owns and clears the creator’s image and content rights, and for how long can I reuse it?
• How do you check team, league and school sponsor conflicts, and college athletes’ NIL reporting?
• Who approves claims in each post, and what is your process for supplements?
• Who checks that each paid post is disclosed correctly, and for how long?
• Can I see a case with a fan action or a sale counted, such as a code use or a sign-up?
