12 Best Performance Marketing and Growth Agencies in 2026

The best performance marketing partners in 2026 fall into two camps: AI creative intelligence platforms like Segwise that power in-house growth teams with cross-network creative analytics and generation, and full-service agencies like Udonis, AppAgent, and Tinuiti that handle media buying, ASO, and creative production end-to-end.

Hiring a performance marketing agency used to be a question of media buying chops. In 2026 it is mostly a question of creative output and creative intelligence. Most ad networks now optimize themselves once you feed them enough variants, so the agencies that actually move ROAS are the ones that ship more good creatives, faster, with a clear read on what is working and what is fatiguing.

This guide covers 12 performance marketing agencies that consistently deliver across paid social, search, ASO, and creative production for mobile games, mobile apps, DTC, and B2B SaaS. We list services, notable clients, and where each one fits, then close with a decision framework so you can pick the right one for your stage and category.

Key Takeaways

• The 2026 performance marketing agency market splits cleanly by buyer type. Mobile gaming and apps go to specialists like Udonis, AppAgent, and Growthcurve, while DTC and B2B go to full-funnel players like Tinuiti, Power Digital, MuteSix, and Directive.

• Creative production volume is now the single biggest differentiator. Agencies without an in-house creative studio struggle to compete on iteration speed, which is where most ROAS improvement comes from in 2026.

• Most agencies will not publish pricing. Expect monthly retainers in the $5K to $15K range for boutique shops and $25K to $100K+ for enterprise full-funnel agencies, plus media spend.

• Brands building lean in-house performance teams pair them with AI creative intelligence platforms like Segwise to get the same creative analytics and generation layer the top agencies run on.

• The right partner depends on category fit, creative bandwidth, and reporting depth, not headcount. Always run a short paid pilot before signing a 12-month contract.

What "performance marketing agency" actually means in 2026

A performance marketing agency is one that is paid to drive measurable acquisition outcomes (ROAS, CPA, installs, leads, revenue) rather than upper-funnel brand metrics. The category covers paid social, paid search, ASO and app stores, programmatic, affiliate, creative production for ads, conversion rate optimization, and attribution.

It does not cover pure brand agencies, PR shops, or design studios that ship assets without owning a media spend goal. It also does not cover SEO-only agencies, although most performance shops now bundle some content and SEO work to support paid efforts.

What changed in 2026: the line between "media buying agency" and "creative agency" has mostly collapsed. Modern algorithms reward variant volume, so the agencies that win are the ones with creative studios attached. This is why several of the agencies on this list now sell creative production as a primary service.

The 12 Best Performance Marketing Agencies in 2026

1. Udonis: Best for mobile game user acquisition at scale

Udonis is an independent mobile-first performance marketing agency that has been running paid UA for mobile games since 2018. They have spent more than $500M on user acquisition for game studios and acquired north of 300M users for clients like SYBO, King, Voodoo, Tastypill, and Playsome. If your business is a mobile game and the goal is profitable installs, this is one of the few agencies built specifically for that job-to-be-done.

The service mix is paid social UA across Meta, TikTok, AppLovin, Unity Ads, Mintegral, and Google App Campaigns, plus an in-house creative production team for video ads, playables, and statics. They also build custom marketing dashboards for clients that want a single view of network and MMP data.

Main services: Paid social UA, media buying across mobile networks, creative production (video, playables, statics), marketing dashboards, mobile game and app marketing strategy.

Notable clients: SYBO, King, Voodoo, Tastypill, Playsome.

When you should hire them. You run a mobile game with at least $50K/month in UA spend, your team is small, and you want a partner that can run campaigns across at least 5 mobile networks while shipping new creatives weekly. Studios in soft launch or geo-expansion phases tend to get the most out of them.

Limitations. Heavy focus on mobile games means they are not the right fit for DTC ecommerce, SaaS, or B2B. Smaller indie studios under $20K/month spend may find the engagement model too senior for their stage.

Pricing: Custom retainer plus media. Not publicly listed.

2. AppAgent: Best for mobile app and game growth with strong creative production

AppAgent is a Prague-based mobile growth agency that blends performance marketing with high-volume creative production for both mobile games and apps. Founded in 2016, the team has worked with Babbel, Asana Rebel, Supercell, Wargaming, Goodgame Studios, Metacore, Wooga, InnoGames, and Scopely. They have been named App Marketing Agency of the Year at the App Growth Awards more than once and have a strong reputation in the European mobile ecosystem.

What sets them apart is the breadth of creative work alongside UA. The creative program covers ideation, production, localization, and testing across 2D, 3D, UGC, and live-action video plus icons, screenshots, feature art, and social assets. They also run their proprietary GamePlan diagnostic for studios in active growth phases who want strategy, UA, ASO, and creative under one roof.

Main services: User acquisition, ASO, ad monetization, data and analytics setup (including SKAN schema), creative production (video ads, playables, store creatives, UGC), GamePlan growth diagnostic.

Notable clients: Supercell, Babbel, Asana Rebel, Wargaming, Goodgame Studios, Metacore, Wooga, Huawei, InnoGames, Scopely.

When you should hire them. You run a mobile app or game in active growth phase, you want a "out-of-house" team that can own UA, ASO, and creative without you stitching together three vendors, and your roadmap includes geo expansion or a new big launch. Studios scaling past their first $1M in monthly spend tend to fit best.

Limitations. Focus is mobile (apps and games), so DTC and B2B brands should look elsewhere. Engagement size and onboarding depth means they are not built for very early-stage indies.

Pricing: Custom retainer plus creative production fees, scoped per engagement. Not publicly listed.

3. Tinuiti: Best for enterprise full-funnel media management

Tinuiti is the largest independent full-funnel performance marketing agency in the U.S., with more than $4 billion in digital media under management and 1,200+ employees. In 2026 they brought their largest-ever client cohort to the Super Bowl, including e.l.f. Beauty, eos, Instacart, and Liquid I.V., and extended several of those programs into the Winter Olympics. They also recently launched AdCopy AI, an internal Gemini-based engine that has driven a 15%+ performance lift for early adopters on Search.

Service depth is the main reason mid-market and enterprise brands hire Tinuiti. They cover paid search and shopping, paid social, Amazon and retail media, SEO, influencer, email and SMS, and connected TV under one roof, plus their proprietary measurement layer Bliss Point. For brands running campaigns across more than five channels, this avoids the data fragmentation that comes with stitching together specialist shops.

Main services: Paid search and shopping, paid social, Amazon and retail media, SEO, influencer, email and SMS, CTV and audio, analytics and media mix modeling.

Notable clients: Etsy, Nestlé, Tommy Bahama, e.l.f. Beauty, eos, Instacart, Liquid I.V.

When you should hire them. You spend $1M+ a month on paid media across at least four channels, you need an integrated measurement story, and you want a single agency that can sit at the table for big tentpole moments like the Super Bowl. Mid-market DTC, retail, and CPG brands fit best.

Limitations. Pricing and engagement structure are built for enterprise budgets, so smaller brands often feel like a low-priority account. Mobile gaming and app studios should pick a specialist.

Pricing: Custom enterprise retainers plus a percentage of media. Not publicly listed.

4. Power Digital: Best for omnichannel growth across mid-market DTC

Power Digital is a San Diego-headquartered performance agency with 200+ employees that pairs paid media with creative, analytics, and PR for mid-market consumer brands. The team has worked with Proactiv, Jenny Craig, and The Honest Company. Their pitch is omnichannel: instead of running paid social in isolation, they integrate paid, content, influencer, and PR around a shared CRM and analytics layer (their internal nova platform).

Where they shine is for DTC brands that have scaled past the obvious paid social plays and need to layer in retention, organic, and CRM to keep CAC down. The team also has solid creative bandwidth and a UX practice for landing pages and CRO.

Main services: Paid media (search, social, display), SEO, content marketing, influencer marketing, PR, CRO and UX, email and CRM, retail media.

Notable clients: Proactiv, Jenny Craig, The Honest Company.

When you should hire them. You run a DTC brand doing $5M to $100M in annual revenue, you want one partner managing paid plus organic plus CRM, and your team is small enough that you cannot staff specialists in each channel. Mid-market consumer brands trying to push CAC down get the most value.

Limitations. Not a mobile gaming or pure B2B SaaS shop. Smaller DTC brands under $1M ARR will likely find the retainer model too heavy.

Pricing: Custom retainer, generally starting in the mid-five-figures per month plus media.

5. Tuff: Best for startups that need senior performance leadership

Tuff is a remote-first growth marketing agency headquartered in Eagle, Colorado, with 50+ team members. They partner with funded startups and established brands for full-funnel performance work and have built a reputation for sending a senior, lean pod into each engagement instead of routing accounts through junior staff. Clients include Xendoo, Sabio, AKKO, and Thnks.

Their approach skews experimental: short test sprints, transparent dashboards, and a focus on combining data with hands-on execution. For a startup that wants someone smart running paid social and SEM without committing to a giant retainer, Tuff is one of the cleaner options.

Main services: Paid social, SEM, content, email, CRO, performance creative, data and analytics.

Notable clients: Xendoo, Sabio, AKKO, Thnks.

When you should hire them. You are a Series A-to-C startup or a funded SMB that wants a senior performance pod for $10K to $30K/month plus media, you need help in 2 to 3 channels, and you want weekly transparency rather than quarterly business reviews.

Limitations. Smaller team means less depth in highly specialized verticals (mobile gaming, retail media, complex enterprise B2B). Not the right fit for $100M+ media budgets.

Pricing: Retainer-based, typically starting around $10K/month plus media. Not publicly listed.

6. KlientBoost: Best for PPC and landing page CRO

KlientBoost is a Costa Mesa-based performance agency built around the loop of PPC plus landing pages plus CRO. Their team of 100+ has worked with Airbnb, Segment, and Stanford University, and they publish unusually detailed playbooks in their content marketing, which is part of how they win mid-market clients. The model is "we will run your ads and rebuild your landing pages so the ads actually convert," which lands well with SaaS and DTC teams that have decent traffic but a leaky funnel.

The PPC bench is strong across Google and Meta and the design team ships landing pages quickly, which matters when conversion gains often come from the page rather than the ad. They also run SEO and email programs but those are usually attached to a paid engagement.

Main services: PPC management (Google, Meta), landing page design and CRO, paid social, SEO, email marketing.

Notable clients: Airbnb, Segment, Stanford University.

When you should hire them. You spend $50K to $500K/month on PPC, your conversion rate is the bottleneck (not your ads), and you want a partner that will rebuild specific funnels rather than just run media. SaaS, ecommerce, and lead-gen businesses fit best.

Limitations. Less strong on programmatic, retail media, or mobile UA. Not a mobile gaming agency.

Pricing: Tiered retainers scaling with media spend. Custom pricing via consult.

7. Disruptive Advertising: Best for mid-market PPC + paid social + CRO

Disruptive Advertising is a Lindon, Utah agency with 100 to 200 staff that runs PPC, paid social, and CRO for mid-market brands. Clients include Guitar Center, Adobe, and Fandango. The team is known for an account-management-first model with frequent communication, which works well for brands that have been burned by agencies that go quiet.

The CRO and analytics arm is one of the strongest in this size bracket. They tend to run thorough audit-then-optimize cycles before scaling spend, which is the right move for mid-market accounts where wasted spend compounds quickly.

Main services: PPC management, paid social, website optimization and CRO, email marketing, analytics consulting.

Notable clients: Guitar Center, Adobe, Fandango.

When you should hire them. You run a mid-market ecommerce, retail, or consumer brand spending $30K to $300K/month on paid, you have an underperforming account inherited from a previous agency, and you want a hands-on partner that will audit before scaling.

Limitations. Less depth in mobile UA and B2B SaaS. Mostly U.S.-focused.

Pricing: Custom retainer plus media. Not publicly listed.

8. Directive: Best for B2B SaaS and enterprise lead generation

Directive is an Irvine, California agency built specifically for B2B and enterprise demand generation. The 200+ team works with ZoomInfo, Cisco, and Betterment and aligns paid and organic effort with revenue rather than MQLs alone. For SaaS companies that have outgrown a generalist agency, Directive is one of the few shops that actually understands a multi-touch buying committee.

Their methodology emphasizes financial modeling and pipeline attribution before campaign work begins, so engagements often start with workshops on ICP and CAC before any media goes live.

Main services: Paid media (search, social), SEO, CRO, analytics and reporting, content marketing, design and creative.

Notable clients: ZoomInfo, Cisco, Betterment.

When you should hire them. You are a B2B SaaS company with $5M+ ARR, you sell into mid-market or enterprise with a 60+ day sales cycle, and you want an agency that will tie media spend to pipeline rather than form fills.

Limitations. Not the right fit for DTC, mobile gaming, or short-cycle ecommerce.

Pricing: Custom retainer, typically starting in the low-five-figures per month plus media.

9. MuteSix: Best for DTC paid social and full-funnel video creative

MuteSix is a Los Angeles full-funnel performance agency owned by Dentsu, with 100 to 250 people. They are best known for DTC paid social and creative-led growth, with clients like MeUndies, Petco, and Ring. The video production muscle is the main reason DTC brands hire them, since they can ship a high cadence of new ads tied to performance feedback.

Beyond paid social, they offer email and SMS, influencer, and CRO. The Dentsu backing means access to wider media tools and data, but engagements still feel hands-on at the account level.

Main services: Paid social, video production, influencer marketing, email and SMS, creative services, CRO.

Notable clients: MeUndies, Petco, Ring.

When you should hire them. You run a scaling DTC brand spending $200K+ a month on paid social and your in-house creative team cannot keep up with the variant volume Meta and TikTok now demand. Beauty, apparel, and consumer hardware brands fit best.

Limitations. Not a mobile gaming, app, or enterprise B2B agency. The Dentsu ownership can lengthen procurement on enterprise deals.

Pricing: Custom retainer plus media and production. Not publicly listed.

10. Croud: Best for global multi-market performance

Croud is a London-headquartered global performance agency with 200+ staff that pairs in-house specialists with a network of on-demand digital experts called "Croudies." This hybrid model lets them scale into local markets quickly without standing up a full office. Clients include Hiscox, IWG, and Boohoo. They work especially well for brands launching across multiple regions where local creative, language, and channel knowledge matter.

Service breadth covers paid search, SEO, programmatic, content, and analytics. The data team is solid and many engagements include a media mix modeling component.

Main services: Paid search, SEO, programmatic advertising, content marketing, analytics and data strategy.

Notable clients: Hiscox, IWG, Boohoo.

When you should hire them. You operate in 5+ markets, your media mix includes search, programmatic, and content, and you want one agency that can localize creative and channel strategy without you running 5 vendor relationships.

Limitations. The networked specialist model can feel less concentrated than a single in-house team. Not a mobile gaming or pure DTC creative shop.

Pricing: Custom retainer plus media, scoped by market. Not publicly listed.

11. HawkSEM: Best for precision paid search and conversion-led campaigns

HawkSEM is a Los Angeles-based performance agency of 50 to 100 people that focuses on paid search, PPC, and CRO with strong attribution practices. Clients include Microsoft, Honda, and Verizon. The team's pitch is "precision marketing," and the proprietary platform ConversionIQ stitches together analytics across channels for cleaner attribution than most clients can build internally.

They are not the loudest agency on this list and their roster skews enterprise. For brands that want a quieter, attribution-heavy partner instead of a flashy creative shop, HawkSEM tends to be the right call.

Main services: PPC management, SEO, CRO, content marketing, analytics and attribution.

Notable clients: Microsoft, Honda, Verizon.

When you should hire them. You spend $100K+ a month on paid search across multiple business lines, attribution is currently a mess, and you need a team that will actually fix the measurement layer before optimizing campaigns.

Limitations. Less strong on paid social creative and not a mobile gaming agency. Mostly U.S.-focused.

Pricing: Custom retainer plus media. Not publicly listed.

12. Performics: Best for global enterprise brands inside the Publicis network

Performics is the global performance arm of Publicis Groupe, with 1,000+ staff and offices across the U.S., Europe, and APAC. Clients include Samsung, Verizon, and Nestlé. As part of the Publicis network they have access to Epsilon's data, CitrusAd's retail media inventory, and broader Publicis creative resources, which matters for global brands that need integrated cross-market campaigns.

Performics is built for enterprises that already have media bought through a Publicis holding company relationship and want to consolidate performance work under one roof. For independent mid-market brands, it is usually overkill.

Main services: Search engine marketing, SEO, affiliate marketing, display and video advertising, conversion optimization, analytics.

Notable clients: Samsung, Verizon, Nestlé.

When you should hire them. You are a global enterprise spending $10M+ on annual media, you want integration with broader Publicis services (Epsilon data, retail media, creative), and you need execution in multiple regions with one contract.

Limitations. Network agency dynamics mean slower decision-making and procurement. Not the right fit for startups, mid-market, or mobile-first brands.

Pricing: Enterprise contracts only. Not publicly listed.

Performance Marketing Agencies Compared

How to choose the right performance marketing agency

Pick based on category fit and creative bandwidth, not headcount. The 2026 lineup splits into clean buckets, and the right choice usually depends on a single dominant variable.

• If you run a mobile game or app, hire a mobile specialist like Udonis or AppAgent. Generalist agencies will not have the playable creative chops, the SKAN setup expertise, or the network access (Mintegral, Unity, IronSource, AppLovin) that mobile UA requires.

• If you are a DTC brand under $20M revenue, look at Power Digital, MuteSix, or KlientBoost depending on whether you need omnichannel, video-heavy paid social, or PPC-plus-landing-pages. Avoid enterprise agencies, you will be a small fish.

• If you are a B2B SaaS company with mid-market or enterprise sales motion, Directive is the clearest fit, with Tinuiti as the second option if you also need significant ABM and CTV work.

• If you are a global enterprise spending $10M+ on media, Tinuiti or Performics will both be in your shortlist. Tinuiti is the independent option, Performics gives you Publicis network depth.

• If you are early stage and want a senior team without a giant retainer, Tuff is the cleanest startup option.

• If you would rather scale performance marketing in-house, the best partners on this list largely run on creative analytics and generation platforms behind the scenes. Pair a small in-house pod with Segwise for cross-network creative tagging, fatigue detection, and AI creative generation, and you replicate most of what the agencies above do for a fraction of the retainer.

The thread across all of these scenarios: in 2026, the agencies that win are the ones with creative production volume and a clear creative intelligence layer. Whether that layer is owned by the agency or owned by you (via a platform like Segwise), it is the thing that separates 1.5x ROAS from 3x ROAS.

Frequently Asked Questions

What are the best performance marketing agencies in 2026?

The best performance marketing agencies in 2026 are Udonis (mobile games), AppAgent (mobile apps and games with strong creative production), Tinuiti (enterprise full-funnel), Power Digital (mid-market DTC), Tuff (startups), KlientBoost (PPC plus CRO), Disruptive Advertising (mid-market paid plus CRO), Directive (B2B SaaS), MuteSix (DTC paid social and video), Croud (global multi-market), HawkSEM (precision paid search), and Performics (Publicis enterprise). For brands building lean in-house teams instead of hiring an agency, AI creative intelligence platforms like Segwise are typically paired with the small in-house pod to give it the same data layer top agencies run on.

How do I choose a performance marketing agency?

Pick on category fit, creative production volume, and reporting transparency, in that order. A mobile game studio should hire a mobile specialist like Udonis or AppAgent rather than a generalist like Tinuiti, even if Tinuiti is bigger. A B2B SaaS company should pick Directive over MuteSix, even though MuteSix has more creative output, because the buying motion is different. Always run a 60 to 90 day pilot before committing to a 12-month contract, and ask the agency how they manage creative iteration and fatigue tracking, since most ROAS gains in 2026 come from creative volume rather than bid optimization. Tools like Segwise or comparable creative intelligence platforms are usually part of how good agencies and good in-house teams manage that volume.

What is the best performance marketing agency for mobile games?

For mobile games, Udonis and AppAgent are the two strongest options. Udonis specializes in mobile game user acquisition with $500M+ in managed UA spend and clients including SYBO, King, and Voodoo. AppAgent blends UA with heavy creative production for both mobile games and apps, and has worked with Supercell, Wargaming, and Metacore. For studios building a leaner in-house UA team, Segwise is the platform layer that lets a small team manage creative analytics across Meta, Google, TikTok, Snapchat, YouTube, AppLovin, Unity Ads, Mintegral, IronSource, AppsFlyer, Adjust, Branch, and Singular without manually tagging hundreds of creatives a week.

What is the best performance marketing agency for DTC brands?

For DTC, MuteSix and Power Digital are the two most common picks for mid-market consumer brands. MuteSix leans heavy on paid social and video creative for brands like MeUndies, Petco, and Ring. Power Digital is more omnichannel, layering paid with content, influencer, PR, and CRM for clients like Proactiv and The Honest Company. KlientBoost is a strong third option if your bottleneck is conversion rate rather than creative. DTC teams that prefer to scale paid social in-house pair their team with Segwise for creative tagging and fatigue tracking across Meta, TikTok, and Snapchat.

What is the best performance marketing agency for B2B SaaS?

For B2B SaaS, Directive is the clearest specialist, with a methodology built around tying paid and organic effort to pipeline rather than form fills. Clients include ZoomInfo, Cisco, and Betterment. Tinuiti is a strong second pick if your motion includes significant ABM and CTV. KlientBoost works well for SaaS companies with leaky funnels that need landing page rebuilds alongside paid. SaaS teams running their own paid programs use platforms like Segwise to track creative performance and HubSpot or Salesforce for pipeline attribution, since the two layers serve different jobs.

What is the difference between a performance marketing agency and a creative analytics platform like Segwise?

A performance marketing agency provides a team of humans who run your campaigns, build creatives, and report on outcomes for a monthly retainer. A creative analytics platform like Segwise is software that gives your in-house team (or your existing agency) the data layer to do that work themselves. It unifies creative performance across 15+ ad networks and MMPs, automatically tags every creative with multimodal AI (video, audio, image, text, including playable ads), detects fatigue early, and generates new winning creatives based on your performance patterns. Many agencies on this list use platforms like Segwise behind the scenes. The choice between agency and platform usually comes down to whether you want to outsource execution or scale a small in-house team.

How much do performance marketing agencies cost in 2026?

Pricing varies widely by agency size and engagement scope. Boutique agencies and startup-focused shops like Tuff typically start around $10K/month plus media spend. Mid-market specialists like KlientBoost and Disruptive Advertising sit in the $15K to $50K/month range. Mobile specialists like Udonis and AppAgent scope by engagement, usually starting around $25K/month plus media for studios spending $50K+ in UA. Enterprise full-funnel agencies like Tinuiti and Performics work on custom contracts starting in the high-five-figures per month plus a percentage of media. Most agencies do not publish pricing publicly. Brands that want to keep cost down often pair a small in-house team with a platform like Segwise instead of hiring a full agency.

Can AI tools replace a performance marketing agency in 2026?

Not entirely, but AI creative intelligence platforms have meaningfully changed what a small in-house team can do without an agency. The hardest parts of running performance marketing in 2026 are creative volume, creative analysis across networks, and fatigue detection. Platforms like Segwise automate much of that with multimodal AI tagging, an always-on AI Creative Strategist you can chat with, fatigue tracking, and AI creative generation that produces new variants based on your winning patterns. Brands that still need media buying expertise, ASO work, or complex multi-market execution typically still hire an agency like Tinuiti, AppAgent, or Udonis, but pair it with a creative intelligence platform to keep iteration speed high.
