Best 7 YouTube & TikTok Ad Agencies in 2026 

YouTube and TikTok are two of the biggest channels for paid video right now, but they reward very different kinds of creatives. A YouTube pre-roll ad has six seconds to earn attention before the skip button appears. A TikTok ad needs to feel native to the feed or it gets scrolled past instantly. The formats, pacing, hooks, and even the way people hold their phones are different.

That's why most brands work with agencies that specialize in one or both platforms rather than trying to figure it all out in-house. The right agency already knows what's working, has the production setup to move fast, and can test creative at the pace these platforms demand.

This guide covers 7 agencies that handle YouTube and TikTok advertising, what each one focuses on, how they price, and which types of brands they're best suited for.

1. Linx Digital

Linx Digital is a performance advertising agency that built its reputation almost entirely on YouTube ads. Founded in 2016 and headquartered in the U.S., the agency started as a YouTube-first media buying shop and has since expanded into Meta and TikTok. 

Their core approach combines data-driven media buying with a proprietary scripting process they use to develop ad creative that converts. They have managed campaigns for clients across e-commerce, SaaS, info products, coaching, and high-ticket services. 

Beyond media buying, their team handles ad creative scripting, audience targeting, campaign structure, remarketing sequences, and performance reporting. They also run a YouTube ads community, with a 3,000+ member Facebook group. 

Key details: 

• Best suited for brands that rely heavily on YouTube for customer acquisition, especially in direct response, info products, and high-ticket e-commerce.

• Pricing is not publicly listed. They offer a free strategy call to assess fit.

• They also offer a training program for in-house media buyers, which can be useful if you want to eventually bring YouTube buying in-house.

2. Disruptive Advertising

Disruptive Advertising is a full-funnel performance marketing agency founded in 2012 and based in Lindon, Utah. With over 130 employees and more than $1 billion in managed ad spend, this is one of the larger independent agencies on this list. 

They work across Google, Meta, TikTok, YouTube, LinkedIn, and other paid platforms, and they position themselves as a partner that goes beyond media buying into full strategy, creative, conversion rate optimization, email marketing, and lifecycle strategy. 

Disruptive has earned over 1,000 positive client reviews and multiple Inc. 5000 appearances. 

They offer a 90-day performance guarantee for qualifying brands, do not require long-term contracts, and are known for turning down clients they do not believe they can help. They also provide free marketing audits as a starting point.

Key details: 

• Broad platform coverage across Google, YouTube, Meta, TikTok, and LinkedIn. Not a single-platform specialist, so expect generalist strength rather than deep YouTube or TikTok expertise.

• Best for mid-market to enterprise brands that want a full-funnel approach across multiple platforms with a single agency partner.

• Minimum project size starts around $5,000. Monthly retainers typically range from $2,500 to $100,000+ depending on ad spend and services.

• Their no long-term contract policy and 90-day performance guarantee lower the risk of trying them out.

3. MuteSix

MuteSix is a performance marketing agency founded in 2014 in Los Angeles. The agency carved out its niche as one of the leading DTC-focused shops, particularly strong on Facebook and Instagram before expanding into YouTube, TikTok, Snapchat, and programmatic. 

Dentsu acquired MuteSix in 2019, and the agency now operates as part of the Dentsu network while maintaining its own brand and team. They manage upwards of $500 million in annual ad spend. A big differentiator is their in-house creative studio, which produces platform-specific video content at scale covering:

• Paid social and search advertising

• TikTok Shop management

• Email and SMS marketing 

• Influencer partnerships 

• Advanced measurement and attribution 

They have worked with brands like Adidas, Petco, Ring, Theragun, MeUndies, and the NHL.

Key details: 

• Strong across Meta, TikTok, Google/YouTube, Snapchat, and programmatic. Also runs TikTok Shop campaigns, which is a plus if you are exploring social commerce.

• Best for DTC and e-commerce brands looking for a full-service performance partner with in-house creative production capabilities.

• Monthly retainers typically start at $25,000. Enterprise clients may invest $150,000+ per month for comprehensive services.

• Being part of the Dentsu network gives them enterprise-level resources, but the premium pricing reflects that. This is not a fit for early-stage brands with limited budgets.

4. The Social Shepherd

The Social Shepherd is a social-first agency headquartered in Bath and London (UK), with a growing U.S. presence. They describe themselves as sitting at the intersection of creative and performance, with a team of 70+ specialists covering organic social, paid social, creative content, influencer marketing, UGC sourcing, TikTok Shop services, and international growth support. 

The agency won Best Large Social Media Agency at the UK Social Media Awards three years running (2023, 2024, 2025). They hold Meta, Google Premier Partner, TikTok, and Pinterest partner status, giving them access to platform betas and early features. Their client roster includes brands like Uniqlo, easyJet Holidays, Premier Inn, and Passenger Clothing.

Key details: 

• Paid social strength spans Meta, TikTok, Pinterest, and Snapchat, with paid search via Google and Microsoft. Particularly strong on organic social and social-native content creation.

• Best for e-commerce and consumer brands, especially UK-based or internationally expanding brands. A strong fit if you want TikTok growth combined with organic social management.

• Pricing is not publicly listed. They offer consultations to scope projects.

• Their direct platform partner status means early access to new ad formats and features, which can give your campaigns a testing advantage on TikTok and YouTube Shorts.

5. Viral Nation

Viral Nation is a global social-first marketing and talent agency founded in 2014 by Joe Gagliese and Mat Micheli. Headquartered in Toronto, Canada, with operations across the U.S. and globally, the agency started as one of the first dedicated influencer talent agencies.

 Today, it has grown into a full-service operation that combines influencer marketing, paid media amplification, content production, community management, experiential activations, and ambassador/affiliate program management. They work with brands like e.l.f. Cosmetics, Audible, A24, Microsoft, Uber, and Walmart. 

Viral Nation also develops its own technology, including CreatorOS (their creator intelligence platform) and Viral Nation Secure (an AI-powered brand safety tool that screens influencer content for risks). The agency claims access to over 18,000 vetted creators and operates campaigns in 30+ countries.

Key details: 

• YouTube and TikTok are primarily accessed through influencer-led campaigns rather than traditional media buying. Also active on Instagram, Snapchat, and Twitch.

• Best for enterprise brands that want influencer marketing at scale with built-in brand safety, especially for global campaigns across multiple markets and languages.

• Campaign minimums reportedly start around $50,000. Pricing is custom-quoted based on scope.

• If your YouTube and TikTok strategy leans heavily on creator partnerships rather than direct response ads, Viral Nation is one of the few agencies built specifically for that at scale.

6. inBeat

inBeat is a performance creative agency based in Montreal, Canada, with operations serving North American clients. They position themselves as a creator-led growth agency, meaning their campaigns start with UGC and micro-influencer content and build outward into paid media across Meta, TikTok, Snapchat, and Google Ads. 

They work across verticals including CPG, e-commerce, mobile apps, DTC, health, and technology. Notable clients include New Balance, Disney, Bumble, NielsenIQ, and Hopper. 

What makes inBeat distinctive is their focus on micro-influencers and creator-driven content rather than celebrity or macro-influencer partnerships. They maintain a proprietary influencer database, handle TikTok Shop setup and management, and offer a suite of free marketing tools including engagement calculators and ad mockup generators.

Key details: 

• TikTok and Instagram are their primary channels. YouTube is not a core focus, so this is mainly a fit if your video ad strategy is TikTok-first.

• Best for brands that want high volumes of authentic, creator-made content for paid social. Particularly suited to CPG, DTC, and mobile app companies.

• Minimum project size starts at $50,000. Average hourly rate ranges from $150 to $199.

• Their micro-influencer model works well for brands that need a constant stream of fresh UGC-style ad creative for testing on TikTok and Meta.
