Top 10 Full-Service Influencer Marketing Agencies in 2025 (Empowering Micro‑Influencers & E-Commerce Brands)

Micro-influencers and user-generated content are reshaping how brands connect with consumers. In 2025, influencer marketing is no longer an experiment but an essential strategy, projected to reach a global market size of over $32.5 billion. Brands are shifting from one-off celebrity endorsements to long-term partnerships with everyday content creators, leveraging micro‑influencers for their high engagement and authenticity. Even Amazon sellers and e-commerce startups are embracing micro-influencer campaigns to diversify beyond the Amazon platform and build direct customer engagement via social media. Choosing a full-service influencer marketing agency can help these brands manage complex campaigns across channels, from creative strategy to analytics, under one roof.

Top 10 Full-Service Influencer Marketing Agencies for 2025

1. Stack Influence

When it comes to micro-influencer campaigns for Amazon sellers and emerging brands, Stack Influence leads the pack. This full-service micro-influencer agency specializes in working with small e-commerce businesses that don’t want to rely solely on Amazon. Stack Influence’s model is to seed free products to a large community of everyday creators in exchange for authentic sponsored posts on social media. In fact, the agency has access to a network of over 10 million micro-influencers (each with 800–20,000 followers), enabling campaigns where a single brand might collaborate with hundreds of niche creators at once. This massive scale of grassroots advocacy generates a flood of user-generated content (product reviews, unboxings, lifestyle photos) and genuine buzz that helps drive sales and brand awareness outside of Amazon’s ecosystem. Stack Influence handles everything from influencer outreach and vetting to campaign logistics and performance tracking, making it a turnkey solution for brands looking to boost online visibility. By focusing on micro-influencers – who often have higher engagement rates and more trust with their followers than big celebrities – Stack Influence helps e-commerce brands convert social media engagement into measurable growth. (Notably, the agency’s co-founder has stated their campaigns achieve high engagement at lower cost, since micro-creators typically charge only a free product or modest fee for their posts.) For startups and Amazon retailers aiming to build a social presence and accumulate lots of UGC quickly, Stack Influence offers an ideal full-service approach.

2. Viral Nation

Viral Nation is a powerhouse in the influencer marketing world, known for being a truly full-service influencer marketing agency with global reach. They have worked with some of the world’s biggest brands – from Disney and Coca-Cola to Uber and Walmart – and have activated over 100,000 creators across campaigns. Viral Nation handles everything in-house: they function both as an influencer marketing agency and as a talent agency, meaning they not only plan and execute brand campaigns but also represent top influencers and creators (securing endorsements and managing their social presence). This dual capacity gives Viral Nation an edge in matching brands with the perfect influencers while ensuring campaigns align with current social media trends and platform algorithms. As a full-service partner, Viral Nation develops strategy, finds and vets influencers, manages creative content production, runs paid amplification, and delivers detailed analytics. For example, they craft campaigns aimed at very specific goals – whether it’s a burst of brand awareness for a product launch or sustained engagement for an ongoing series. Viral Nation prides itself on integrating influencer initiatives with other marketing efforts to “cut through the noise” – they weave influencer content into broader digital campaigns to maximize impact. The agency even built its own technology (like the Viral Nation CreatorOS platform) to track social attribution and ROI from influencer collaborations in real time. With operations in over 30 countries and content delivered in 15+ languages, Viral Nation is equipped to scale campaigns internationally. They also emphasize brand safety and have AI tools (e.g. Viral Nation Secure™) to analyze creators’ content for any risks, ensuring endorsements are on-brand and compliant. In short, Viral Nation offers enterprise brands a one-stop, data-driven solution for influencer marketing – from big-picture strategy down to execution and performance optimization – truly embodying “full-service” in this space.

3. Whalar

Whalar has made a name for itself as a creator-first full-service agency that helps transform brands into cultural phenomena. Whalar positions itself as an independent “creator and social” agency built to turn brands into “cultural drivers” through influencer-led strategies. In practice, Whalar provides end-to-end influencer campaign services: they handle strategy and creative concept development, cast and manage creators, produce high-quality content, and amplify it via paid social ads – all while keeping a laser focus on measurable outcomes like brand lift and sales. Whalar’s approach is highly data-driven and tech-enabled. They developed an internal platform called Foam that pulls real-time metrics from Instagram, TikTok, YouTube, and more to help shortlist the perfect creators for each campaign based on audience data and performance stats. Their process often follows a Build → Activate → Measure → Scale framework: first, they do deep research (sometimes convening creator focus groups) to shape the campaign brief; next, they set platform-specific creative guidelines (e.g. the right hooks for TikTok, or storytelling angles for Instagram); then, they execute the campaign end-to-end, handling creator contracts, content approvals, and even in-person production through their “creator campuses” (studios where creators and brand teams can collaborate in real time). Finally, Whalar doubles down on amplification and measurement – they treat influencer content as ads in their own right, running paid media behind top-performing creator posts to boost reach and lower CPA compared to traditional ads. They even commission independent studies (e.g. with Nielsen) to validate the ROI of their influencer campaigns, which have shown impressive returns (e.g. 2.41× ROI in some cases). With this blend of creative talent and analytical rigor, Whalar’s campaigns don’t just generate buzz – they deliver consistent, full-funnel results. Brands working with Whalar can expect a premium, hands-on partnership that unlocks the full creative power of social content creators while still hitting key performance metrics

With a focus on transparency and optimization, Obviously continuously monitors performance metrics and can tweak campaigns in real-time.

5. The Influencer Marketing Factory

The Influencer Marketing Factory (IM Factory) is a global full-service agency that has carved out a niche in engaging Gen Z and Millennial audiences. Co-founded by Alessandro Bogliari in 2018, this agency focuses on the platforms where young consumers spend their time – notably TikTok, Instagram, and YouTube – and has helped clients like Sony Music, Google, Dunkin’ and more boost brand awareness and sales through influencer campaignscouncils.forbes.com. What sets IM Factory apart is its trend-driven strategy: they pride themselves on spotting rising social trends (TikTok challenges, viral memes, emerging YouTube formats) before they hit the mainstream, and then crafting campaigns that allow influencers to ride those trends in an authentic way. In other words, they understand internet culture and help brands become part of it. For example, in one campaign mentioned, their team turned a Kohler faucet promotion into a creative storytelling challenge during Milan Design Week – encouraging lifestyle influencers to integrate the product into engaging content (like morning routine vlogs and baking videos) rather than overt ads, resulting in over 1.5 million views. The Influencer Marketing Factory provides end-to-end service: starting with audience research and psychographic mapping to ensure they understand what motivates the target demographic. They ideate campaign concepts, hand-pick influencers, manage all outreach and negotiations, and supervise content creation to make sure it aligns with the brand yet feels native to the platform. They also set granular performance benchmarks (views, engagements, click-throughs) and measure against them throughout the campaign. Thanks to this hands-on approach, IM Factory’s campaigns tend to achieve both cultural resonance and marketing results. If a brand wants to tap into youth culture on social media – say, launching a challenge on TikTok or working with up-and-coming creators on Instagram – The Influencer Marketing Factory has the expertise to design a campaign that “speaks TikTok” and still meets business objectives. They truly bridge the gap between viral content and brand strategy in a full-service package.

6. The Shelf

Their sweet spot is at the intersection of cultural relevance and measurable performance – meaning they create influencer content that is trendy and engaging, yet always tied to driving real outcomes like sales or sign-ups. The Shelf has developed a proprietary analytics platform centered on an “Interest Graph” model. Instead of just matching brands with influencers based on surface-level demographics or follower counts, The Shelf digs deeper into why an influencer’s audience engages. Their system analyzes content themes, audience behaviors, and conversations to find creators whose followings have genuine affinity for the brand’s niche. This results in highly authentic partnerships – tapping into tight-knit communities where the impact is strong. With a data-first approach, The Shelf turns what can be complex multi-platform campaigns into ROI-driven programs. They manage campaigns from creative conception through execution and post-campaign analysis, often utilizing their Optimization Flywheel process to iteratively improve results. They’re also known for blending bold creative storytelling with rigorous data science, proving that influencer marketing can be both emotionally resonant and operationally precise at the same time. For example, The Shelf often incorporates whitelisting and paid amplification of influencer content (with precise targeting) as part of their campaigns, ensuring that great influencer posts get in front of even more of the right people. One case study saw The Shelf recruit dozens of beauty micro-influencers to create tutorial-style content for a cosmetics brand, then turning those Instagram and TikTok posts into paid ads that drove direct e-commerce sales. This full-funnel approach – from creative content to conversion – makes The Shelf a valuable full-service partner, especially for mid-market brands and D2C companies that need their influencer campaigns to directly boost revenue. In summary, The Shelf marries creativity with accountability, using data insights at every step to make sure influencer collaborations actually deliver results.
