Love seeing athletes and brands team up? Let’s dive into some sports influencer marketing examples that show how fitness, performance, and personality come together to fire on social media.

Gymshark influencer marketing case study

Talk about the Whitney Simmons and Gymshark influencer marketing campaign case study? Gymshark is that go-to fitness brand for both pro athletes and sports amateurs. It’s famous for clever designs, top-notch performance gear, and influencer-driven hype that keeps it at the top of the fitness game.

Audience

It attracts fitness-loving women and men who treat the gym like therapy. They’re into self-improvement, body positivity, and looking good while hitting that last rep. The same audience follows Whitney Simmons, a mega fitness influencer. Her feed? Workouts, meal tips, and little life moments.

And the way she delivers it? Totally effortless. It’s like she’s chatting with you over coffee while you’re both planning to hit the gym. That balance of inspiration and authenticity is what makes people stick around. Whitney’s followers trust her because she’s real − she talks about the highs, the lows, and everything in between.

Collab format

Instead of just slapping her face on a campaign, Gymshark made Whitney part of the creation process. She wasn’t just promoting − she was designing. Together, they dropped the Adapt Collection, a dreamy lineup of sports bras and leggings in four colors (pink, black, blue, and brown). Whitney shared behind-the-scenes content, workouts in the gear, and personal stories tied to confidence and strength.

Curious how B2B brands are winning with influencers? Let’s check out some B2B campaigns that prove it’s not just consumer brands that can make big waves online.

Kittle & Nickie Saunders

Talk about one of the best B2B influencer marketing case studies. Kittl is a design tool − or as they like to say, a playground for creatives, designers, and art directors. Whether you’re putting together a mockup, a poster, or a book cover, Kittl makes it super easy to create whatever visual you need.

Audience

Enter Nickie Saunders, a content branding expert, marketer, and creator with nearly 200K followers on Instagram. Her audience? Creators who are hungry for tools, tips, and tricks to level up their content, especially around graphic design and editing. Basically, the exact crowd Kittl wants to reach.

Collab format

They went B2B influencer marketing style: one killer IG Reel. Nickie introduced Kittl as a Canva alternative, broke down its features, and demoed the tool in action, including a fun effect where letters of different colors merged into one word. 

To top it off, she told followers to drop a “design” in the comments for exclusive free access − but only if they followed her first. Smart funnel move.

  • 163 comments

  • Boosted brand recognition for Kittl as a Canva contender

Interactive and fast demo of the tool showcasing its main features, rather than simply talking about them.

Plus, the interactive call-to-action made people engage and convert..

Active Campaign & Joanna Young

ActiveCampaign, a platform that helps small and mid-size businesses automate their marketing processes.

That’s why they teamed up with Joanna Yung, a micro-influencer on TikTok. Her content? She shares how to decode AI, MarTech, and marketing solutions. Her followers are marketers and business owners looking for tools that actually make their lives easier. 

Perfect overlap with ActiveCampaign.

Collab format

This authentic B2B influencer marketing case study is a classic example of a sponsored video review. Joanna walked through ActiveCampaign, showing off the dashboard, highlighting features, and demonstrating how marketers can actually use it in real life. 

The campaign’s main theme? Promoting work-life balance while getting things done − totally aligned with her audience.

  • 90% of the comments section is the tool link requests. 

Why did it work

Then her insights on how to make this life even easier with the tool automation features and AI. 

And the best part is how in detail she presented the tool’s value. 

Notion & Mylene Mae

  • 489K+ views

  • 33.2K likes

  • 220+ comments

  • Tons of her audience got inspired to finally set up their own Notion system, making this a standout example of Instagram influencer marketing.

Why did it work

The product is shown naturally, as part of her everyday life, not a classic demo. Plus, the influencer genuinely shows she’s been using this tool for a while, not just for the collab launch. So it comes across as a kind of insider tip that her followers can use to live just as interesting and productive a life.

And the best part? She wraps it up with a question about her audience’s own plans, not a pushy ‘buy this.’ That’s what we call next-level native advertising!

Now, it’s time for games 👇

Gaming influencer marketing examples

If you’re in the gaming industry, you’re in the right place. Below are some awesome influencer marketing tactics: their hooks, collab formats, and results.

Roblox & @Echogaming

Roblox is basically a massive virtual playground where creativity runs wild. It’s an online platform where users can create, share, and play games made by other players using Roblox Studio.

Their audience? Primarily kids and teens aged 9–16. However, lately, it’s also pulling in older players, developers, and casual gamers who love building and exploring new worlds.

And that’s why they chose for this collab @EchoGaming − a YouTuber known for reviewing PC and mobile games with a delivery that’s catchy, descriptive, and super engaging. His followers? Just the right mix of gamers who can’t wait to discover new games and get fully into the gameplay.

Collab format

They teamed up for a sponsored YouTube video where @EchoGaming talked about why now’s the perfect time to play Roblox. He showed off key gameplay moments, shared his favorite parts, and kept it all fun and authentic. 

Bonus: he dropped a QR code in the video and a link in the caption, making it super easy to jump in and play.

Results: 5.5K+ views

Why did it work

Yeah, this Reel clearly looks like an ad and the creator even called it out in the video description. But what worked perfectly is that he’s actually playing the game and inviting others to join him. 

Teens in the gaming audience really value the chance to hang out with an influencer they admire, even if it’s just virtually. Later, they’ll be telling everyone in their chats, ‘I played Roblox with @EchoGaming!’

The key insight? If you’re promoting a game with an influencer, make sure they actually play it.

Cube Chaos & @Timetogrind

Cube House is a fast-paced puzzle and building game where players construct and manage cube-shaped structures. The game challenges players’ spatial reasoning and problem-solving skills. 

How? Gamers stack, rotate, and fit cubes in increasingly complex levels. 

Their audience?

Puzzle lovers, strategy gamers, and casual players. The game fits for all ages as it features colorful graphics, intuitive controls, and rewarding progression. Besides, multiplayer modes and community challenges further engage players who enjoy competing or collaborating online.

For this video gaming influencer marketing campaign they invited @timetogrind − a micro gaming YouTube creator with 36K+ subscribers. His content? A mix of different indie and mainstream games, plus weekend livestreams. 

His delivery? Catchy, funny, and sometimes delightfully weird − a tone that resonates with a tight-knit, loyal gaming audience who value honest takes and humor.

Collab format

It was a sponsored YouTube video where he played Cube Chaos for 1.5 hours, diving into the tutorial, features, and rules while reacting naturally in his signature style.

Results

The video racked up 5K views with strong engagement and retention (28 comments) − impressive numbers for such a niche, long-lasting game.

Why did it work

A smart use of micro-influencer marketing. While playing, he reacts emotionally to different parts of the game, showing genuine excitement for the product — which naturally drives interest in buying the game. Classic tactic, but not every streamer can pull it off so authentically. 

Also, @timetrogrind delivered full immersion into the Cube House experience − from explaining the rules to showing tutorials on how to play.

Micro-creators like him are niche and approachable, which drives trust, retention, and conversions.

Now that we’ve explored sports, B2B, and gaming case studies on influencer marketing, let’s shift gears to Instagram👇

Why did it work 

Authenticity met aesthetics. The video felt more like a genuine couple moment than an ad, which made the outfit and the brand feel relatable. 

Campbell’s approach didn’t interrupt the flow of the content. Instead of a hard sell, the promo code was woven into moments that felt organic, like showing a product in use or having the characters casually mention it. This way, viewers received the offer as part of the story rather than an intrusive advertisement. 

By aligning the promo code with the emotional narrative and lifestyle context, Campbell turned casual viewers into shoppers, proving that an authentic connection can drive real engagement in fashion marketing.

FAQs

What’s the biggest takeaway from these influencer marketing case studies?

That authenticity wins every time. The campaigns that crushed it weren’t the flashiest − they were the ones where the creator genuinely loved the product. People can feel real connection.

How did small brands compete with big ones?

They leaned into niche. Instead of chasing mega influencers, they found micro-creators who already had their dream customers’ trust. Fewer followers, deeper impact.

Any major flops worth learning from?

Oh, totally. One brand picked a huge influencer who didn’t fit their vibe at all. Engagement tanked. Moral of the story? Alignment over audience size, always.

What made the best campaigns stand out?

Storytelling. The influencers didn’t just “post”−they shared experiences. Real moments, not salesy scripts. That emotional hook is what makes people hit “buy.”

So, what should we steal, I mean, learn from these brands?

Play the long game. Build relationships with creators, not one-off deals. When the partnership feels natural, the audience feels it too. That’s where the magic happens.
