Top 8 user acquisition agencies in 2026

Acquisition costs keep climbing, platform rules keep shifting and the channels that worked last year rarely perform the same way this year. All these variables make guesswork very expensive. That’s why you need a user acquisition (UA) partner that knows how to turn spend into installs, signups and conversions with precision.

But precision on any single channel is no longer enough to win. The biggest gains in 2026 come from orchestration: paid media, organic discovery, retention and measurement working as one connected system, each channel feeding the next. 

This is the real dividing line between user acquisition agencies today. Some execute isolated tactics. Others build acquisition engines that connect the top of the funnel to activation, retention and revenue.

We built this list around that distinction. Every agency below can drive measurable growth, but the strongest treat user acquisition as an orchestrated system rather than a set of disconnected tasks.

TL;DR

How we chose these agencies

When ranking these agencies, we looked at what actually predicts whether a user acquisition partner will move your numbers, and weighted the list around the criteria that matter most when you’re spending real budget to acquire users.

• Channel expertise: We prioritized agencies with demonstrable depth in the channels that matter most for a brand’s audience, rather than generalists spread thin across everything. 
• Industry specialisation: The playbook for a mobile game looks nothing like the playbook for a B2B SaaS product. That’s why we favored agencies with a clear vertical focus and a track record in it. 
• Attribution and reporting maturity: We looked for partners with strong attribution and reporting infrastructure. Think transparent dashboards and a focus on downstream metrics like retention and revenue. 
• Proven performance outcomes: We looked for documented case studies and hard numbers, such as lower cost per acquisition or real user growth, backed by named clients. 

Every agency on this list fits these requirements. Where they differ is fit, which is why each entry calls out who it’s best for.

Understanding the different user acquisition models (and how this impacts your decision)

User acquisition agency is an umbrella term covering several different models, and they’re not interchangeable. Knowing which one you’re talking to prevents mismatched expectations and wasted budget.

The 8 best user acquisition agencies to accelerate growth in 2026

These are the agencies companies turn to when they are ready to stop experimenting and start scaling user growth with predictable, repeatable results.

1. Moburst: Best for mobile apps that need high-volume installs backed by ASO and creative testing

📌 TL;DR: A mobile-first agency that scales app installs and quality users through paid media, ASO (app store optimization) and creative optimization.

🧩 Acquisition model: Paid UA

📈 Overview: Moburst has deep experience running paid UA across Meta, Google and Apple Search Ads. The agency feeds winning ad creative from constant A/B testing back into campaigns. They then layer app store optimization (ASO) on top so paid spend and organic store visibility compound to drive installs down at a lower cost per install.

🌍 Industries: Mobile apps, gaming, fintech

💲 Pricing: Custom based on scope and growth targets

✔️ Top services:

• Paid user acquisition
• App store optimisation (ASO)
• Creative testing and production
• Retention and analytics

🏆 Results: Moburst combined paid UA with ongoing ASO to drive Mailwise past 500,000 app installs while cutting cost per install by 70%. 

✅ Strengths: Enterprise-grade experience with global brands; strong across the full mobile stack (UA, ASO, creative); built for high-volume scaling.

⚠️ Keep in mind: Premium and enterprise-oriented, so it’s the best fit for apps with real budget to scale, less so for very early-stage or tightly budgeted teams.

2. Udonis: Best for mobile game studios that need creative-led user acquisition

📌 TL;DR: A mobile game marketing agency that acquires players through high-volume ad creative and performance media buying.

📈 Overview: Udonis studies a game’s genre and audience, then produces and rapidly tests large batches of video ad creative. The agency also buys media across social platforms and ad networks and optimizes creatives, placements and bids to bring in loyal players at scale.

🧩 Acquisition model: Paid UA

🌍 Industries: Gaming, entertainment, mobile apps

💲 Pricing: Custom per campaign

✔️ Top services:

• Paid user acquisition and media buying
• Ad creative production and testing
• ASO
• Analytics and campaign optimisation

🏆 Results: Udonis has managed $500M+ in UA and creative budgets and acquired millions of users for mobile games, including over 70 million downloads for Bottle Flip 3D.

✅ Strengths: Mobile-gaming specialization; very high creative-testing velocity; large-scale media-buying track record.

⚠️ Keep in mind: Almost exclusively focused on mobile games, so it’s a specialist fit for game studios only.

3. Skale: Best for SaaS and B2B teams that want organic search to become a predictable acquisition channel

📌 TL;DR: Builds organic acquisition engines that turn SEO, content and AI search into a measurable, compounding source of signups and revenue.

🧩 Acquisition model: Full-funnel growth, organic-led

📈 Overview: Skale wins full-funnel search demand by targeting both the queries buyers use when they’re researching and when they’re ready to sign up. Then, product-led content, authority link building and GEO compound so the brand surfaces in Google and AI answers. Success is measured in signups, SQLs, MRR, pipeline and revenue.

🌍 Industries: SaaS, B2B, fintech

💲 Pricing: From $4,000 per month

✔️ Top services:

• SEO and organic growth strategy
• GEO (AI search) optimisation
• Product-led content
• Authority link building 
• AI brand mentions

🏆 Results: In under 18 months, Skale grew Rezi’s monthly signups by 243% and revenue by 86%, turning search into the resume platform’s primary acquisition channel. 

✅ Strengths: A compounding, ownable acquisition channel measured on revenue and signups rather than rankings; 100+ SaaS and tech clients, including HubSpot, TravelPerk and Typeform; strong in the emerging AI search space.

⚠️ Keep in mind: Skale is organic growthled, so it isn’t the fit for teams that need paid media or app-install campaigns. And it’s not for brands chasing vanity metrics like quick traffic spikes. Organic builds over months, then compounds.

4. Growth Hackers: Best for brands wanting experimentation-focused performance marketing

📌 TL;DR: Growth-marketing agency that scales users through rapid, cross-channel experimentation across paid, SEO, content and CRO.

📈 Overview: The Growth Hackers team runs structured growth sprints, forming a hypothesis, then testing paid ads, SEO, content, email and landing-page changes. They then double down on whatever acquires users best. The model suits companies hunting for a repeatable acquisition channel before committing a heavy budget.

🧩 Acquisition model: Full-funnel growth

🌍 Industries: SaaS, eCommerce, mobile apps, B2C and B2B

💲 Pricing: Project and retainer options

✔️ Top services:

• Growth marketing and experimentation
• Paid media (Google, Meta, paid social)
• SEO and content marketing
• Conversion rate optimisation

🏆 Results: Growth Hackers helped edtech app Magrid enroll 48,000+ students globally through a cross-channel growth strategy. 

✅ Strengths: Fast, test-driven approach that surfaces cheap acquisition channels; broad cross-channel coverage; flexible project or retainer terms suited to startups and SMBs.

⚠️ Keep in mind: Broad and experimentation-led rather than a category specialist, so it’s less of a fit if you need deep expertise in one lane, like mobile app UA or enterprise SaaS demand gen.

5. inBeat: Best for consumer and app brands that want UA driven by UGC and influencer creative

📌 TL;DR: Creative-growth agency that drives app installs and signups by turning UGC and influencer content into high-performing paid social ads.

📈 Overview: inBeat sources vetted micro-creators and produces high volumes of UGC. It runs and rapidly tests that content as paid ads across TikTok, Meta, Snapchat and Google to lower cost per install.

🧩 Acquisition model: Paid UA 

🌍 Industries: Mobile apps, DTC and eCommerce, CPG, consumer brands

💲 Pricing: Custom, based on scope and creative volume

✔️ Top services:

• UGC and influencer content production
• Paid social (Meta, TikTok, Snapchat, Google)
• Creative testing and ad optimization
• App-install and user acquisition campaigns

🏆 Results: For DNA-testing app Genomelink, inBeat rebuilt the paid creative around high-volume UGC and cut customer acquisition cost by 73% while lifting registration completions by 124%.

✅ Strengths: Very high creative-testing speed through UGC; strong on TikTok and Meta paid social; large vetted creator network; proven install and CPA results.

⚠️ Keep in mind: Creative and paid-social-led, so it’s strongest for consumer, app and DTC brands on social platforms and a weaker fit for B2B, search-led or complex enterprise sales motions.

6. REPLUG: Best for apps ready to scale paid UA across channels beyond Meta and Google

📌 TL;DR: Performance-driven app marketing agency focused on transparent paid user acquisition, ASO and retention for mobile-first brands.

📈 Overview: REPLUG diversifies spend beyond Meta and Google into Apple Search Ads, TikTok, programmatic and OEM placements like Xiaomi. Clients own their ad accounts, and the agency fixes MMP tracking so every dollar is attributed cleanly and campaigns scale only where ROAS holds.

🧩 Acquisition model: Paid UA

🌍 Industries: Mobile apps, mobile games, subscription apps, fintech, news and media

💲 Pricing: Custom based on scope and ad spend

✔️ Top services:

• Paid user acquisition
• App store optimisation (ASO)
• Retention and mobile CRM
• Growth consulting and attribution

🏆 Results: For recipe and meal-planning app KptnCook, REPLUG rebuilt the UA engine beyond Meta and Google, adding TikTok, Reddit, Snapchat and IronSource. This lifted iOS ROAS by 1,338% while cutting cost-per-trial by 15.9% and iOS CPI by 17.5%.

✅ Strengths: Strong multi-channel reach beyond Meta and Google (including OEM); high transparency with client-owned ad accounts; measurement and attribution adapted to a privacy-first environment.

⚠️ Keep in mind: REPLUG only takes on apps that are ready to scale. And it’s app-focused, so it isn’t a fit for B2B, SaaS or web-first acquisition.

7. Upgrow: Best for companies that want UA paired with SEO and long term growth

📌 TL;DR: Full-funnel B2B performance agency that generates sales-ready leads through paid media and SEO working together.

📈 Overview: Upgrow runs paid search, paid social and SEO under one roof.

With this approach, paid delivers fast pipeline while SEO compounds lower-cost organic leads over time.

🧩 Acquisition model: Full-funnel growth

🌍 Industries: B2B SaaS, tech and software, fintech

💲 Pricing: Monthly retainers from $5,000, fees scale with account size and spend

✔️ Top services:

• Paid search and paid social (Google, LinkedIn)
• SEO and content
• Conversion rate optimization and landing pages
• Lead automation and analytics

🏆 Results: For B2B event platform EventMobi, Upgrow rebuilt paid search into a full-funnel engine. The agency grew paid revenue 80% year-over-year, new customers 58% and ROAS 56% over 12 months

✅ Strengths: Transparent, published pricing; strong in competitive B2B tech and SaaS; pairs fast paid results with compounding SEO.

⚠️ Keep in mind: Focused on B2B tech and SaaS lead generation, so it’s less suited to mobile app installs, eCommerce or pure consumer UA. Also a smaller, boutique team rather than an enterprise shop.

8. RocketShip HQ: Best for creative-led UA with high-volume ad production

📌 TL;DR: Performance-creative agency that scales app installs by producing and testing high volumes of ad creative against ROAS.

📈 Overview: RocketShip HQ mines app reviews and competitor ads for insights, produces large batches of video and UGC creative, then runs a weekly test-and-learn loop across platforms. The agency uses post-ATT measurement like SKAN and media-mix modelling to scale only profitable creative.

🧩 Acquisition model: Paid UA

🌍 Industries: Mobile games, subscription apps, consumer apps

💲 Pricing: Based on ad volume and spend

✔️ Top services:

• Performance ad creative (video and UGC)
• Paid user acquisition (Meta, TikTok, Google, Apple Search Ads)
• Creative testing and iteration
• Post-ATT measurement and analytics (SKAN, MMM, LTV)

🏆 Results: For a leading meditation app, RocketShip HQ tested 300+ creatives to drive 300k+ installs at 120%+ new-user ROAS, restoring profitable scale after ATT disrupted tracking.

✅ Strengths: Creative-testing engine tuned to CPI and ROAS; strong post-ATT measurement; specialist mobile app and gaming expertise.

⚠️ Keep in mind: Built for mobile apps and games with real budget, as fully managed services require $50,000/month+ in ad spend.

6 tips for evaluating user acquisition agencies

The right user acquisition agency will fit your goals, audience and budget. Here’s what to look for before you commit.

1. Determine whether they have experience in your category

User acquisition differs completely by product. Mobile gaming specialists won’t operate like B2B customer acquisition agencies. Look for proof they’ve grown apps or products like yours: case studies, performance metrics, real CPA and retention improvements. If they can’t show relevant work, they’re not the right fit. 

What to ask: What’s the closest client to us you’ve worked with, and what results did you drive?

2. Analyze agency model fit by stage

Early-stage teams want a lean, experiment-first setup that proves unit economics before scaling. Growth-stage companies need a full team accountable to CAC and LTV. Enterprises need orchestration and senior strategy. Match the model, project, retainer, performance or fractional, to your stage, and avoid buying more scope than you need. 

What to ask: Have you grown a product like ours, at our stage, and can you show the numbers?

3. Be realistic about your budget

UA pricing varies with creative volume, channels and optimization cycles. Define your goals first so agencies can scope realistically. Clarify three things: your primary performance goals, the channels you want to invest in and the creative or technical assets you already have. 

What to ask: How do you charge, and what exactly is included?

4. Match their services to your actual needs

Not every brand needs a full UA team. Some need creative testing, others multi-channel media buying, others funnel optimization. Choose the agency that fills your real gaps rather than the one with the longest service list. The right partner sharpens targeting and tightens spend without unnecessary complexity.

What to ask: Which channels do you run in-house, and where is your deepest expertise?

5. Assess full-service vs channel-specific partners

A channel specialist goes deep on one lever, which is ideal when you have a strong in-house team and one clear gap. A full-service partner owns the whole funnel, which matters as your channel mix grows and the cost of stitching vendors together compounds.

What to ask: How do paid, organic and retention connect in your approach?

6. Consider attribution and reporting 

Look closely at an agency’s reporting frameworks before signing. Consider transparency (do you own your accounts and data?), the right metrics (retention, activation, and revenue, not just installs), and a forward-thinking approach to first-party measurement under signal loss (now that privacy changes have made attribution far less reliable). 

What to ask: How do you attribute results, and which downstream metrics do you report on?

Choosing the right user acquisition partner

The right user acquisition partner depends on what type of products you have and what profiles of users you serve. 

If you’re a mobile app or game, you need an agency that excels at ASO and creative testing for maximizing installs. If you’re a B2B or SaaS company, acquisition means demos and pipeline won through content, third-party mentions and organic growth. 

Whichever camp you’re in, the strongest agencies treat acquisition as an orchestrated system that connects acquisition to activation and retention, not isolated tactics. Judge each on that, plus proof in your category and how they measure results.

For SaaS and B2B teams, that’s Skale’s focus: turning organic search into a predictable, compounding acquisition channel measured on signups and revenue.

User acquisition agency FAQs

What does a user acquisition agency do?

A user acquisition agency runs the paid and organic campaigns that bring new users or customers to a product, then optimizes them to lower what each one costs. The strongest agencies also track what those users do after install, tying spend to activation, retention and revenue.

How can I tell if a user acquisition agency is the right fit?

The clearest signal is a case study from a company in your category and at your stage that shows the CPA, ROAS or retention numbers they actually moved. Beyond relevant proof, look for transparent reporting, ownership of your own ad accounts and data, and a focus on revenue impact rather than vanity metrics. 

What are the benefits of hiring a user acquisition agency?

When you hire a user acquisition agency, you get immediate access to specialists in media buying, organic growth, targeting and attribution without building that team in-house. That usually means faster scaling and lower cost per acquisition. 

How do I choose a user acquisition agency?

Choose on category fit first, then match the engagement model to your stage and the channel specialty to your real gaps. Early-stage teams usually want a lean, experiment-first setup, while growth-stage companies need a full team accountable to CAC and LTV.

What are the best customer acquisition agencies?

The best agency depends on your model: Skale suits SaaS and B2B teams, while Moburst, Kurve and REPLUG specialise in mobile app growth. There’s no single winner, because increasing app installs works completely differently from generating B2B pipeline. 

How much does a user acquisition agency cost?

Most user acquisition agencies charge monthly retainers that depend on channels, scope and how much you spend on ads. Skal, for example, starts from $4,000 per month. App-focused agencies often quote custom pricing on top of a minimum ad spend, while some work on performance or percentage-of-spend models. 

Are user acquisition agencies worth it?

For most companies spending seriously on growth, yes. A specialist agency usually lowers acquisition costs faster than an in-house generalist can. Value starts to show up once your ad spend or growth targets outgrow what one internal marketer can manage across channels.
