Disclaimer: Growth Folks is not a marketing agency and does not offer agency services.
This article is purely editorial. None of the agencies listed paid to be featured. Every marketing company included here was selected based on independent research, public data, and our own evaluation.

We reviewed agency websites, analyzed case studies, and cross-checked reputations on platforms like Google Reviews and Clutch. Listings are reviewed regularly to keep information current and accurate.

Growth marketing has become a different game in the last few years.

It’s no longer just about running campaigns or testing a few channels. Today, it’s about how everything connects. Acquisition, activation, retention, monetization. If those pieces don’t work together, growth stalls. Simple as that.

That shift has changed what companies expect from a growth agency.

In a place like New York, where you have access to some of the most experienced digital marketing agencies, the bar is even higher. It’s not enough to execute. Agencies need to understand how to drive sustainable growth across the entire funnel, not just one part of it.

I’ve spent time looking into how different agencies approach this. Not just what services they offer, but how they actually think about growth. How they structure experiments, how they use data, and how they turn insights into consistent results.

Because not every “growth agency” really operates like one.

This list focuses on the teams that do.

If you’re trying to find the best growth marketing agencies in New York, these are the ones worth paying attention to.

TL;DR

Before we get into the full breakdown, here’s a quick look at a few standout agencies:

  • NoGood: Strong on data and execution. They work a lot with SaaS, B2B, and eCommerce teams, plugging in as a growth partner with full-funnel performance marketing. 
  • GrowthRocks: Very product and data-focused. They help SaaS and B2B companies scale through product-led growth, SEO, and AI-driven experimentation.
  • Fueled: More on the tech + growth side. They combine marketing, analytics, and automation to help brands scale, especially through lifecycle and testing.
  • M&C Saatchi Performance: Built for scale. They handle large, performance-driven campaigns across paid media, programmatic, and mobile for industries like fintech and eCommerce.
  • MSELLEO: Best when conversion is the bottleneck. Focuses on improving UX and turning traffic into actual results.

What Does Growth Marketing Look Like in 2026?

Growth marketing has matured. A lot.

Now, it’s about how everything connects across the funnel. If acquisition, conversion, and retention don’t work together, growth stalls.

What’s changed is how teams approach the problem.

Instead of thinking in channels, they think in systems. Paid brings users in, CRO turns them into customers, email marketing and lifecycle keep them engaged, and content marketing supports the whole journey. 

Everything feeds into the same goal: sustainable growth.

There’s also more pressure to get it right. Budgets are tighter, competition is higher, and performance marketing alone isn’t enough to carry results. You need stronger fundamentals: better messaging, cleaner data, and tighter execution across every touchpoint.

And the data backs that up:

  • As reported by HubSpot, 50% of marketers actively focus on CRO, making it one of the top optimization priorities.
  • Per the same source, 56% of marketers say improving conversion rates is easier today than it was a decade ago.
  • 71% of consumers expect personalized experiences, and most will switch if they don’t get them.
  • Around 65% of revenue comes from existing customers, not new ones.
  • Smartphone adoption is already at ~91%, so growth is shifting toward extracting more value from current users.
  • Data-driven companies are 23x more likely to acquire customers and 19x more likely to be profitable.
  • Content marketing costs 62% less than traditional marketing and generates about 3x more leads, as reported by Loopex Digital.

So what’s the takeaway?

Growth today is about making the system work. The teams that win are the ones that connect data, creative, and execution across the entire customer journey.

Why Hire a Growth Marketing Agency in New York

Bringing in a growth marketing agency in New York shifts how you run marketing.

You’re working with teams that are used to pressure. Fast cycles, constant testing, and a clear expectation: results have to show up.

That usually translates into a few things:

  • Better tooling and cleaner data to work from.
  • People who’ve already handled different channels and know where things tend to break.
  • The ability to scale without rebuilding your internal marketing team.
  • Closer attention to performance, not just campaign output.
  • An outside view that helps catch what your team might be too close to see.

Now, here’s where things get real.

A lot of companies are already doing “enough” marketing. Still, the results feel inconsistent.

As Loopex Digital also notes, only 61% of marketers feel their strategy is actually effective, and 40% struggle to prove ROI. 

That’s the gap. Not effort or channels. Clarity.

And that’s usually what a good growth agency fixes.

My Unique Methodology: How I Rated the Agencies in This List

Not every list out there follows a clear process. This one does.

I didn’t just skim websites or copy what each agency says about itself. I looked at how they actually operate and what kind of results they’ve been able to deliver across different clients.

To keep things consistent, I evaluated each agency based on a few key factors:

  • Real client feedback across platforms like Clutch and Google Reviews.
  • Quality of case studies and whether results were clearly backed by data.
  • Industry focus (SaaS, eCommerce, B2B, fintech, etc.).
  • How they approach growth marketing beyond acquisition.
  • Ability to connect channels like performance marketing, email marketing, and content.
  • Consistency across multiple clients, not just one standout project.

That last point matters more than it seems.

Anyone can showcase a strong result. What you want is a team that can repeat that performance, adapt to different contexts, and still deliver.

Now that you have the context, let’s get into the top growth marketing agencies in New York City right now:

1. NoGood

🔗 Website: nogood.io

NoGood plays in the growth space the way you’d expect from a New York agency: fast, experimental, and heavily data-driven.

They focus on B2B, SaaS, and eCommerce brands, building dedicated growth squads that combine strategists, creatives, and data scientists around each client.

That structure changes how campaigns are executed. Instead of siloed teams, everything runs as one unit focused on solving specific growth bottlenecks.

2. GrowthRocks

🔗 Website: growthrocks.com 

GrowthRocks leans into classic growth hacking, but with a sharper focus on how things actually work in New York. That local context shows up in how they approach strategy and execution.

Instead of running generic playbooks, they adapt based on market behavior, which matters a lot in a city where competition is aggressive and fast-moving.

Their work centers on identifying weak spots in the funnel and fixing them through data, experimentation, and continuous optimization. That includes everything from product-led growth to performance marketing and AI-driven insights.

It’s less about isolated campaigns and more about building systems that improve over time.

Agency Strengths:

  • Growth hacking
  • Product-led growth (PLG)
  • AI consulting
  • SEO strategy
  • Performance marketing (PPC)

🔎 Industries Served: SaaS, B2B services, eCommerce, Marketplaces, B2C services, InfoProducts.

  • Proven experience across multiple industries.
  • Clear focus on transparency and collaboration.

Who This Agency is Best For: Teams operating in competitive markets that need constant testing and iteration to stay ahead.

My Personal Take: Growth hacking sounds great in theory, but execution is where most teams fall short. Agencies that stick to testing and optimization cycles tend to outperform over time.

3. Fueled

🔗 Website: fueled.com 

Fueled comes at growth from a product-first angle. Instead of starting with campaigns, they start with the product and build from there.

They operate as a technology consultancy, which means their work goes beyond marketing into product development, data systems, and user experience.

That shift changes how growth happens. Rather than pushing traffic into a funnel, they focus on improving the product and lifecycle so growth becomes more natural and scalable.

Their capabilities span analytics, automation, attribution, and testing, all tied together to create a more efficient growth system.

Agency Strengths:

  • Marketing automation & lifecycle campaigns.
  • Analytics & insights.
  • Central data management.
  • Attribution tracking & optimizations.
  • A/B testing & workflow optimization.

🔎 Industries Served: Mobile, Retail, Hospitality, FinTech, E-commerce, Technology.

💙 Clients Include: MGM Resorts, Warby Parker, IKON Pass.

📣 Check the agency’s case studies.

Why Choose Them:

  • Proven experience across different industries.
  • Data-driven strategies built around client needs.
  • Full range of growth and product-focused services.
  • Experienced team of specialists.
  • Strong focus on transparency and collaboration.

Who This Agency is Best For: Companies where product, data, and marketing need to work as one system, not separate pieces.

My Personal Take: At a certain stage, growth stops being just marketing. It becomes product, data, and experience working together. That’s exactly where this kind of team fits.

4. M&C Saatchi Performance

🔗 Website: mcsaatchiperformance.com

Scaling paid ads sounds great… until performance starts dropping while spend keeps going up. That’s exactly the kind of problem M&C Saatchi Performance is built to handle.

They operate deep in performance marketing, running campaigns across paid search, social, programmatic, and app channels. But the real focus isn’t just launching campaigns. It’s keeping them efficient as things scale.

Everything runs on data. Budgets shift, creatives get tested, targeting gets refined. Constantly. That’s how they keep acquisition costs under control even at higher volumes.

Working with brands like Amazon and SEGA also tells you the level they’re used to playing at. This is a serious scale, not a small-budget experiment. 

Agency Strengths:

  • Paid search.
  • Paid social.
  • Programmatic advertising.
  • App marketing.
  • App store optimization.
  • Commerce media.
  • Affiliate marketing.

🔎 Industries Served: FinTech, E-commerce, Gaming, EdTech, Hospitality, Entertainment, Travel, Fitness, SaaS, Crypto.

💙 Clients Include: Amazon, Beam Suntory, SoundCloud, SEGA.

📣 Check the agency’s case studies.

Why Choose Them:

  • Expertise in performance marketing across diverse industries.
  • Data-driven strategies aligned with business goals.
  • Comprehensive range of digital marketing services.
  • Proven experience with high-profile clients.
  • Commitment to transparency and collaboration.

Who This Agency is Best For: If you’re already spending serious budget on acquisition and need to scale without losing efficiency, this is where they shine.

My Personal Take: At scale, small mistakes get expensive fast. Teams that know how to keep performance steady while budgets grow are worth their weight in gold.

5. MSELLEO

🔗 Website: mselleo.com 

More traffic won’t fix a bad experience. If people land on your site and don’t convert, growth just stalls.

That’s where MSELLEO leans in. Beyond bringing users in, they focus on what happens after the click.

Their work blends digital marketing with UI/UX and development, which means campaigns and experience are built together, not separately. And that matters more than most teams think.

Because at the end of the day, better design and smoother journeys usually translate into better numbers. More leads, more sales, less wasted traffic.

Agency Strengths:

  • Digital marketing.
  • E-commerce solutions.
  • UI/UX design.
  • Web development.
  • SEO optimization.

🔎 Industries Served: Financial services, E-commerce, Technology, Startups, and various other sectors.

💙 Clients Include: sportskompaniet.no, sensoryfriendly.net, Mirinsight.com.

📣 Check the agency’s case studies.

Why Choose Them:

  • Expertise in creating engaging digital strategies.
  • Strong focus on user-centric design.
  • Custom solutions across different industries.
  • Proven track record with notable clients.
  • Wide range of service capabilities.

Who This Agency is Best For: If you’re getting traffic but not enough conversions, this is the kind of team that can fix that gap.

My Personal Take: A lot of teams jump straight into “more ads.” But sometimes the real win is fixing the experience first. That’s usually where the fastest gains come from.

6. Growth Hackers

🔗 Website: growth-hackers.net

Some brands don’t have a traffic problem. Actually, what they have is a perception issue.

Growth Hackers leans into that gap. Instead of starting with acquisition, they start with how your brand is experienced and remembered.

Copy, design, and web all come together here. Not as separate deliverables, but as one system that shapes how people see and trust your business.

That shift tends to change everything downstream. Better engagement, stronger recall, and a brand that doesn’t get lost in the noise.

Agency Strengths:

  • Branding
  • Content marketing
  • Digital advertising
  • SEO
  • Web design

🔎 Industries Served: B2B, B2C, Healthcare, Manufacturing, SaaS, Small businesses, Web3.

💙 Clients Include: Intouch Insight, Qlik, SmartHead.

📣 Check the agency’s case studies.

Why Choose Them:

  • Expertise in crafting distinctive brand identities.
  • Comprehensive service offerings.
  • Proven track record with diverse industries.
  • Data-driven strategies.
  • Focus on delivering measurable results.

Who This Agency is Best For: A good fit when your brand blends in too much and needs a clearer identity before scaling further.

My Personal Take: Throwing more budget at ads won’t fix weak positioning. When the brand clicks, everything else tends to perform better.

7. Good Moose

🔗 Website: goodmoose.co 

Acquisition gets all the attention. Retention is where things compound.

Good Moose builds around that idea. Instead of treating channels separately, they connect media, creative, and lifecycle into one flow.

Email, SMS, and audience testing aren’t side tactics here. They’re central to how growth happens, especially for eCommerce brands.

Over time, that approach builds a more stable revenue base, not just short-term spikes.

Agency Strengths:

  • Email & SMS marketing
  • Amazon advertising
  • Attribution strategy
  • Creative services
  • Audience & creative testing
  • Analytics & reporting
  • Media management

🔎 Industries Served: E-commerce, Technology, Consumer goods, Financial services, Health and wellness.

💙 Clients Include: Sol de Janeiro, Summer Fridays, GLDN, Sundance.

📣 Check the agency’s case studies.

Why Choose Them:

  • Expertise in performance marketing.
  • Data-driven approach.
  • Proven success with diverse industries.
  • Comprehensive service offerings.
  • Focus on sustainable growth.

Who This Agency is Best For: Makes the most sense for brands that already generate sales and want to increase repeat purchases and lifetime value.

My Personal Take: Most teams underestimate retention until CAC starts climbing. Once that happens, this kind of setup becomes way more valuable.

8. Zest Digital

🔗 Website: zestdigital.com 

Some agencies talk about growth, while others tie everything back to revenue. Zest Digital sits firmly in that second group.

Their work revolves around combining SEO, PPC, and content into a single system that drives qualified traffic and converts it.

The key difference is how tightly those pieces are connected. Instead of running isolated campaigns, everything feeds into improving traffic quality and conversion rates. That’s what leads to more predictable results over time.

Agency Strengths:

  • Search engine optimization (SEO)
  • Pay-per-click (PPC) advertising
  • Content marketing
  • Social media advertising
  • Web design and development

🔎 Industries Served: Automotive & Transport, Banking/Financial Services, Business Services, Construction & Renovation, Consulting/Advisory.

💙 Clients Include: Hanson, Polythene, Maxipos.

📣 Check the agency’s case studies.

Why Choose Them:

  • Proven track record of delivering significant revenue growth.
  • Full growth marketing capabilities across channels.
  • Data-driven strategies aligned with business goals.
  • Award-winning campaigns recognized in the industry.
  • Focus on sustainable business practices.

Who This Agency is Best For: Companies that want a clearer link between marketing efforts and actual revenue outcomes.

My Personal Take: When everything is connected properly, results stop feeling random. That’s usually the difference between “doing marketing” and actually growing.

9. JumpTech Solutions

🔗 Website: jumptechsolutions.com 

Some teams want control over how that growth happens. JumpTech leans into that.

Their work is heavily driven by data, but not in a “reporting for the sake of reporting” way. The focus is on using that data to adjust strategy, improve visibility, and keep performance moving in the right direction.

SEO, content, paid ads, and email all play a role here, but what matters is how they connect. Visibility brings people in, engagement keeps them interested, and retention closes the loop.

That full-cycle view is what helps turn traffic into something more consistent over time.

Agency Strengths:

  • SEO and content marketing
  • Social media marketing
  • Email marketing
  • Paid advertising
  • Market analysis and strategy
  • Conversion rate optimization (CRO)

🔎 Industries Served: Automotive, Aviation, Real estate, Healthcare, Government, Retail, Logistics & Supply chain, Telecom.

💙 Clients Include: Audi, Tupperware, Decathlon.

Why Choose Them:

  • Data-driven strategies aligned with business goals.
  • Proven track record with reputable clients.
  • Comprehensive range of marketing services.
  • Strong focus on ROI and sustainable growth.

Who This Agency is Best For: Companies that want a clearer system behind their marketing, instead of campaigns running in isolation.

My Personal Take: When everything is connected properly, performance becomes easier to manage. That’s usually where consistency starts showing up.

10. Firon Marketing

🔗 Website: fironmarketing.com 

If your goal is leads, not just traffic, Firon Marketing keeps things pointed in that direction.

They operate as a full-service agency, covering SEO, paid media, and content, with a strong emphasis on performance. Every channel is set up to support lead generation and conversion.

Search, social ads, and content are built to work together, which helps campaigns stay aligned with actual business outcomes.

The result is a setup focused less on vanity metrics and more on what drives growth.

Agency Strengths:

  • Search engine optimization (SEO).
  • Paid media management.
  • Content development.
  • Web design and development.
  • Email marketing.

🔎 Industries Served: B2B, SaaS, Tech.

💙 Clients Include: Skillt, Damine, CareCard.

Why Choose Them:

  • Data-driven strategies aligned with business objectives.
  • Proven success across different industries.
  • Full-service capabilities for end-to-end marketing.
  • Continuous optimization to improve ROI.

Who This Agency is Best For: B2B or SaaS teams that care more about qualified leads than just increasing traffic numbers.

My Personal Take: More traffic sounds good until you realize it doesn’t convert. Focusing on lead quality instead usually makes a bigger impact.

11. Spark Growth

🔗 Website: sparkgrowth.com 

Running campaigns in healthcare or wellness isn’t just harder. It’s restrictive. Messaging, targeting, and even the way you talk about results have limits.

Spark Growth works inside those constraints. They help brands move forward without running into compliance issues halfway through a campaign.

Instead of forcing generic tactics, they adjust strategy to fit the space. That includes how content is written, how audiences are approached, and which channels make sense.

It’s a more controlled way of growing, but for regulated industries, that’s exactly the point.

Agency Strengths:

  • Digital marketing strategy.
  • Paid advertising.
  • Social media management.
  • Content creation.
  • Influencer marketing.
  • Analytics & insight.

🔎 Industries Served: Pharmaceuticals, Healthcare & medical devices, Women’s health, Wellness.

💙 Clients Include: UNICEF, GSK, Exeltis.

📣 Check the agency’s case studies.

Why Choose Them:

  • Expertise in regulated industries.
  • Woman-owned and women-led agency.
  • Commitment to employee well-being and supportive culture.
  • Proven track record with reputable clients.

Who This Agency is Best For: Companies in healthcare or wellness that can’t afford compliance mistakes but still need to grow.

My Personal Take: This isn’t a space where you can “try things and see what happens.” You need to know the limits before you push them. That’s the real value here.

12. Dreamdat

🔗 Website: dreamdata.io

Most B2B teams don’t have a clear view of what’s driving revenue. Data sits in different tools, reports don’t match, and decisions get made on partial information.

Dreamdata tackles that directly. It pulls data together, cleans it, and shows how marketing and sales actually contribute to revenue.

That changes how teams operate. Instead of guessing which channels work, you can see the full path from first touch to closed deal.

Agency Strengths:

  • Revenue attribution
  • Customer journey analysis
  • Data integration
  • Performance analytics
  • Audience segmentation

🔎 Industries Served: B2B companies, Marketing agencies, Technology firms, SaaS providers.

💙 Clients Include: Blackline, Clio, Gorgias, Paystone.

📣 Check the agency’s case studies.

Why Choose Them:

  • Specialized in B2B revenue attribution.
  • Automated data processing for clarity.
  • Actionable insights to improve marketing and sales.
  • Proven success with reputable clients.

Who This Agency is Best For: Teams dealing with messy data and unclear attribution across multiple channels.

My Personal Take: When attribution is off, everything feels random. Fix that, and you stop wondering where to invest.

13. Full Funnel Growth

🔗 Website: ffg.digital 

Splitting strategy, creative, and development across different teams slows everything down. Things get lost between handoffs.

Full Funnel Growth avoids that by keeping everything in one place. Strategy, execution, and technical work all move together.

That setup makes it easier to launch, test, and adjust without waiting on multiple teams to align. It’s a more direct way of working, especially for brands trying to scale without adding complexity.

Agency Strengths:

  • Full-stack growth strategy
  • Go-to-market strategy
  • Development projects
  • Data projects

🔎 Industries Served: eCommerce, B2B, SaaS, Food & beverage, Fashion, Beauty.

💙 Clients Include: Tea Forte, Apercu Eyewear, and Andrea Gomez.

📣 Check the agency’s case studies.

Why Choose Them:

  • In-house expertise across marketing, design, and development.
  • Custom strategies aligned with business goals.
  • Proven success with high-profile clients.
  • Transparent reporting and performance tracking.

Who This Agency is Best For: Companies that don’t want to coordinate multiple vendors just to get things moving.

My Personal Take: Most delays come from coordination, not from strategy. When everything sits under one team, things just move faster.

Ready to Scale Your Growth in NYC With the Right Agency?

Not every agency that talks about growth actually works that way.

Some focus on channels, while others look at how everything connects and build from there. You’ll notice the difference quickly once you start working with them.

The agencies on this list lean toward that second approach.

Now, it’s about fit.

Your stage, your goals, and how your current marketing team is set up all play a role. The right growth partner should match how you operate and where you want to go next.

If something feels off in the early conversations, it probably is. If they ask the right questions and push your thinking a bit, you’re on the right track.

Frequently Asked Questions (FAQs)

What is a growth marketing agency, and how is it different from a traditional marketing agency?

A growth marketing agency looks at the whole funnel, not just traffic or leads. They work on how users convert, how they come back, and how revenue grows over time. Testing and data are a big part of how they operate.

A traditional advertising agency usually stays closer to execution by channel.

What should I look for when choosing a growth marketing agency in New York?

Pay attention to how they think. Most agencies will list similar services. What matters is how they approach problems. Do they talk about testing, prioritization, and data? Or just channels and deliverables?

Also, check if they’ve worked with businesses like yours. That context saves time.

How much does it cost to hire a growth marketing agency in NYC?

There’s no fixed range. Some charge monthly retainers. Others work around performance. Pricing depends on scope, channels, and how involved they are.

In New York, rates tend to be higher. The upside is speed and experience.

Are growth marketing agencies worth it for early-stage startups?

Depends on where you are. If you’re still figuring out your product or audience, an agency won’t solve that. Once you have some traction, they can help you move faster and avoid wasting budget. Timing matters more than anything here.

What industries do growth marketing agencies in NYC usually specialize in?

You’ll see a lot of focus on SaaS, fintech, eCommerce, and B2B. But what matters more is if they understand your growth model. That’s what shapes the strategy.
