A growth marketing agency helps a company acquire, convert and retain customers through coordinated experiments. This guide compares 15 U.S. agencies through named work and customer feedback, from College HUNKS’ connected TV program to Latham Pool’s website redesign. Start with the problem your business needs to solve: reaching more buyers, converting existing demand or increasing customer value.
Compare 15 growth marketing agencies
Anderson Collaborative leads our list for integrated creative, media and measurement, followed by Nativz for content and social growth. Tinuiti, Power Digital and NoGood complete the first five with different approaches to media allocation, retail growth and qualified acquisition. The table connects each agency with work described in its profile.
| Agency | Growth model | Work to explore |
|---|---|---|
| Anderson Collaborative | Integrated creative, media and sales reporting | College HUNKS |
| Nativz | Creative testing and social audience growth | JAMNOLA; Axolotl Planet |
| Tinuiti | Media allocation across demand-building channels | Leafguard |
| Power Digital | Retail acquisition, creative and lifecycle work | Pura Vida |
| NoGood | Qualified acquisition for complex services | Spring Health |
| Directive | B2B search content and demand generation | Sumo Logic; iCIMS |
| KlientBoost | Focused experiments with in-house teams | Airbnb |
| Single Grain | Content and website conversion growth | LS Building Products |
| Metric Theory | User acquisition and value per user; now Monks | GoFundMe |
| WebFX | Search visibility and manufacturing inquiries | HydroWorx |
| Disruptive Advertising | CRM-informed bidding for higher-value deals | Matterport |
| NP Digital | Global search tied to closed sales | Tektronix |
| Wpromote | Shared paid and organic customer insight | Intuit QuickBooks |
| Seer Interactive | Audience research, brand and conversion experience | Latham Pool |
| Thrive Internet Marketing Agency | Centralized support with local franchise execution | Restoration 1 |
The useful distinction is where growth is getting stuck. Leafguard needed better media allocation, Spring Health needed qualified providers, and Latham needed a clearer path from research to inquiry. Their projects call for different combinations of acquisition, conversion and customer insight.
How to structure a growth marketing engagement
Begin with one business constraint and a baseline, not a promise to activate every channel. Decide whether the immediate constraint is acquisition, conversion, or retention. Then define the commercial outcome, leading indicators, test window, and rule for stopping or scaling an experiment. Channel owners, creative owners, analytics owners, and the client’s sales or product team should share one experiment log.
Before signing, ask for the first engagement milestones: a measurement and data-access plan, an agreed baseline, a prioritized test backlog, and a reporting cadence that states the hypothesis, work shipped, result, uncertainty, and next decision. Scope and cost can include strategy, media management, creative production, landing-page or software work, analytics implementation, and media spend. Buyers should ask which components are included, who owns the accounts and data, and what requires a separate statement of work.
1. Anderson Collaborative
Official website: Anderson Collaborative
Anderson Collaborative is a 360 performance marketing and advertising agency with a Miami-area office in Coral Gables. Its work can connect strategy, creative, paid media, landing-page work, and measurement around the client’s goals. Custom software, technology, and AI infrastructure support engagements where they are scoped, rather than being assumed to be included in every contract.
This model is relevant when the offer, landing page, measurement setup, or follow-up process is as important as channel-level traffic.
The College HUNKS program shows how that coordination works for a franchise network. Anderson Collaborative brought television creative, connected TV distribution and revenue reporting into one program. Through June 2026, the published case reports more than $14.5 million in CRM-matched revenue against $1.32 million in spend. That is matched revenue, not an estimate of incremental sales caused by advertising.
In the same case, Performance Marketing Director Joe Fortunato describes the team as a partner in the brand’s growth. The practical distinction is the connection between production, media and the customer’s sales data. It gives a franchise operator a way to evaluate the program beyond impressions or completed video views.
2. Nativz
Official website: Nativz
Nativz is headquartered in Dallas and shares Anderson Collaborative’s Miami-area office in Coral Gables. Its public service mix centers on social media management, organic social and content, paid social, strategy, and content production. It is relevant when growth depends on creative velocity and platform-native storytelling.
Its JAMNOLA work gives that model a concrete shape. For the New Orleans attraction, Nativz turned existing client footage into ten ad edits in one month, using social listening to choose themes and campaign response to guide the next edits. The case reports 9.4x ROAS over 14 days for the winning “Hot in New Orleans” ad. That figure describes one creative and its test window.
Organic content is another part of the practice. In a December 2022 Clutch interview, Axolotl Planet CMO Jake Pak described ten TikToks exceeding 15 million views and an audience of more than one million followers across platforms. Those historical audience results and the JAMNOLA paid campaign show two different ways the agency puts creative to work.
3. Tinuiti
Official website: Tinuiti
Tinuiti offers commerce, streaming, social, paid search, AI SEO, CRO, email and SMS, affiliate, influencer, creative, and measurement services. Its commerce and measurement teams work across retail acquisition channels.
For Leafguard, the growth problem was how to allocate money across channels. Last-click reporting favored search and affiliates while undervaluing Facebook, direct mail, linear TV and YouTube. Tinuiti analyzed historical media data with its rapid media-mix model and recommended a different allocation. The agency reports 12% lower acquisition cost and 30% growth in prospects during the first two months of application.
That example makes Tinuiti relevant when several channels depend on one another to create demand. In the June 2026 Serta Simmons Bedding appointment announcement, CMO Tim Oakhill highlighted its integration of media, data and measurement. His statement explains the selection; it is not a report of completed campaign results.
4. Power Digital
Official website: Power Digital
Power Digital lists paid search, programmatic, paid social, TikTok, PR, influencer, brand partnerships, SEO, lifecycle, website optimization, mix modeling, and data science. That service mix brings acquisition and customer retention into the same engagement.
Its Pura Vida engagement, published in November 2024, combined creative, email and PPC. The fashion team refined inefficient keywords, expanded non-brand search, improved shopping campaigns and tested email. Power reports 136% quarter-over-quarter revenue growth for that combined engagement, rather than a result attributable to one isolated channel.
The mix matters for a retailer whose next purchase is as valuable as the first. On Power’s company site, L’AGENCE Chief Digital Officer Ashley Bryan describes its attention to business economics and strategic planning. That is a more useful reference for an acquisition-and-retention brief than a list of advertising platforms alone.
5. NoGood
Official website: NoGood
NoGood describes paid growth across Google, Meta, TikTok, LinkedIn, and emerging AI search, plus measurement architecture, attribution modeling, conversion optimization, growth engineering, and performance creative. Its work combines creative and technical experiments around a defined growth problem.
Spring Health’s provider recruitment campaign shows a growth assignment with a specific qualification problem. NoGood tailored targeting by geography and provider licensing requirements, then monitored lead quality across channels. Its case reports a 113% increase in provider-qualified leads. These were prospective mental health providers, not employer customers or a measure of patient revenue.
The case includes feedback from Senior Marketing Manager Cassandra Lenz, who describes proactive recommendations, flexibility when plans change and attention to Spring Health’s business goals. That combination is relevant to teams whose acquisition problem involves attracting the right participants to a service, rather than maximizing raw form volume.
6. Directive
Official website: Directive
Directive is a B2B growth agency with content and technical SEO, paid media, performance creative, programmatic, RevOps, CRO, GTM, demand generation, and AEO services. Its focus is longer sales cycles where lead quality, pipeline influence, and sales handoff matter.
Its Sumo Logic content program addressed a product that served several technical markets. Directive developed a glossary for early research and application-and-integration content for buyers closer to a decision. The work also included internal linking, on-page SEO and changes to pages where visitors were leaving. The 2021 case document dates this as historical work.
There is a separate customer perspective in Emily January’s January 2025 Clutch review. The iCIMS senior manager describes an engagement that expanded from North American SEO and paid media into EMEA SEO, content writing and a GA4 audit. She praises communication and B2B SaaS knowledge, while also noting account-team changes. It is a useful account of an evolving relationship across acquisition and measurement.
7. KlientBoost
Official website: KlientBoost
KlientBoost lists paid media, CRO, SEO, performance creative, and business intelligence. Its financial-goal and data-workflow emphasis may suit teams that need to connect post-click conversion work to commercial goals.
The Airbnb case study documents experiments carried out alongside an existing in-house PPC team. KlientBoost tested keyword-specific ads, refined campaigns and organized negative keywords. Over the three-month project, it reports a 22% increase in click-through rate and a 7% reduction in cost per conversion.
Airbnb Online Marketing Technology Manager Catherine Lam describes how the collaboration challenged the team’s existing PPC thinking and moved quickly into implementation. The example supports a focused experimentation role for KlientBoost, including situations where a company wants outside expertise without replacing its internal marketing department.
8. Single Grain
Official website: Single Grain
Single Grain offers SEO and CRO, paid media, analytics, creative, technical and local SEO, content, UX and reporting. Its multichannel scope may suit companies reducing dependence on a single acquisition channel.
For LS Building Products, Single Grain started with a small content footprint and few quote requests. It expanded content across the buying journey and improved the user experience. The agency reports a 229% increase in site conversions over 12 months. The case describes website conversions; it does not establish the value of completed building-product sales.
On its customer stories page, Nextiva CMO Yaniv Masjedi credits Single Grain’s marketing support with helping the company’s brand and business. For a buyer, the LS example is the more specific evidence of how content and conversion work fit together, while the testimonial offers a customer’s view of the relationship.
9. Metric Theory
Official website: Metric Theory
Metric Theory lists SEM, paid social, display remarketing, shopping, feeds, video, Amazon, mobile, and CRO. Its current site identifies the business as Monks, formerly Metric Theory. The portfolio below reflects work under the Metric Theory name.
The GoFundMe case describes a strategy for profitable user growth across markets and records the team’s 2019 US Search Awards win for Best Use of Search: Finance. GoFundMe Head of Growth Marketing Jesse Boland’s testimonial on the site describes growing new users and revenue per user together. That is the distinguishing growth question here: whether acquisition can expand without sacrificing the value of the users acquired.
10. WebFX
Official website: WebFX
WebFX offers SEO, PPC, social advertising, CRO, local SEO, content, analytics and CRM, plus web services. Its structured one-provider model may suit businesses placing several foundational functions with one partner.
Its HydroWorx case combines a tailored SEO program with web design. For the hydrotherapy equipment manufacturer, WebFX worked on content, relevant search terms, crawlability and the website experience to increase qualified inquiries. The case reports 131% more organic contact-form submissions. Those submissions are a lead measure, not booked equipment sales.
The same page includes feedback attributed to HydroWorx, without naming the speaker, praising WebFX’s attention to what the business needs from the partnership. The case is useful for a manufacturer whose growth depends on both reaching specialist buyers and making the next step clear once they arrive.
11. Disruptive Advertising
Official website: Disruptive Advertising
Disruptive Advertising offers paid search, paid social, SEO, Amazon, lifecycle marketing, CRO, creative, and data analytics. It may suit direct-response programs where account structure, offers, landing pages, and channel efficiency all affect performance.
Its Matterport case shows why a lower cost per lead is not always the right target. Disruptive connected offline CRM conversion data to Google and improved the signals used for automated ROAS bidding. The agency reports a move from roughly 800% to 1,500% ROAS across consecutive 60-day periods, while cost per conversion increased as campaigns pursued more valuable deals.
Matterport Paid Media Director Didier Bizimungu provides a testimonial in the case, describing the team’s support. For a company with uneven deal values, the substantive point is the feedback from sales data into bidding. The example links acquisition decisions to value rather than treating every form submission as equal.
12. NP Digital
Official website: NP Digital
NP Digital describes multi-touch attribution, marketing mix modeling, SEO incrementality, full-funnel optimization, and target setting for paid and earned media teams. Its company overview also describes paid media, earned media and creative support, including options for SMB and franchise clients.
In its Tektronix case, NP Digital used offline CRM data to assign conversion values by product and region across more than 20 countries. It moved Google Search campaigns to target-ROAS bidding after collecting enough data. The agency reports an 82% year-over-year increase in closed sales delivered by paid search, without an increase in media spend, for that comparison.
Tektronix Senior Digital Media Specialist Riley Grubb says in the published testimonial that quantifying global results helped the company allocate marketing dollars. The growth model is especially relevant when a business already generates leads but needs a better connection between marketing activity and the sales those leads become.
13. Wpromote
Official website: Wpromote
Wpromote connects paid, earned, and owned media with data, analytics, creative, and strategy. Its customer-journey framing may suit brands comparing integrated media and measurement support.
Its Intuit QuickBooks work joined paid and organic search teams around customer intent and first-party data. Lifetime-revenue information informed conversion values, bidding and the products promoted through search ads. The work illustrates how an established acquisition program can improve when teams share the same understanding of customer value.
In the case, Brad Neelan, Head of Holistic Search at Intuit QuickBooks, praises the trust and collaboration between the teams. Wpromote is a relevant comparison for a business with several products and customer segments, where growth depends on choosing the right offer and measuring its longer-term value.
14. Seer Interactive
Official website: Seer Interactive
Seer Interactive focuses on AI research and strategy, SEO, GEO, paid media, analytics, creative services, and CRO. It may suit brands assessing customer intent and experimentation across organic and paid channels.
The Latham Pool brand refresh and website redesign is a useful example of growth work beyond acquiring traffic. Seer used audience research, usability testing, SEO and paid-media data to clarify the brand story and remove friction from the buying journey. The nine-month project brought positioning, content and interface design together. Seer reports a 122% year-over-year increase in lead rate.
Latham VP of Marketing Gail Conroy credits Seer’s consumer insights, collaboration and project management in the published case. This is relevant when a company has market recognition but its website makes research and inquiry harder than they need to be. The reported lead-rate change belongs to the combined redesign, not to SEO alone.
15. Thrive Internet Marketing Agency
Official website: Thrive Internet Marketing Agency
Thrive Internet Marketing Agency offers SEO, PPC, social, content, email, website optimization, CRO, and web development. Its foundational multichannel scope may suit businesses building several digital functions at once.
Its Restoration 1 case covers web development, SEO, paid search and reputation management across 180 locations in the described program. Thrive adapted local pages to each franchisee’s market, strengthened emergency-service calls to action and supported location-level review collection. The work addresses a familiar franchise problem: sharing a brand without forcing every territory into the same plan.
The case’s customer feedback, attributed to Restoration 1 without a named speaker, discusses the depth of the account team and its ability to work within franchisees’ fixed budgets. That is the useful operating comparison for a multi-location buyer: centralized expertise paired with local execution and an affordable scope for individual operators.

Frequently asked questions
What are the best growth marketing agencies in the USA?
This guide’s leading growth marketing agencies in the USA are Anderson Collaborative, Nativz, Tinuiti, Power Digital, and NoGood. Companies should compare agencies by channel expertise, measurement discipline, creative support, and ability to connect marketing activity to revenue.
What is a growth marketing agency?
A growth marketing agency helps companies acquire, convert, and retain customers through testing, channel execution, and measurement. Services often include paid media, SEO, CRO, analytics, creative testing, email, and landing page strategy. The goal is to find repeatable growth instead of isolated campaign launches.
How do marketing firms differ from growth marketing agencies?
Marketing firms can cover many services, including branding, PR, creative, media, content, and digital execution. Growth marketing agencies usually focus more directly on acquisition, conversion, retention, analytics, and experimentation. Some firms do both, but the buyer should ask how the agency measures success and how often it adjusts strategy based on results.
What are the best U.S. ad agencies for growth marketing?
For growth marketing, strong U.S. ad agency options include Anderson Collaborative, Nativz, Tinuiti, Power Digital, Directive, KlientBoost, and Disruptive Advertising. The best choice depends on whether the brand needs paid search, paid social, B2B demand generation, ecommerce growth, CRO, or full-funnel strategy. A growth agency should be selected for fit, not name recognition alone.
When should a company hire a growth marketing agency?
A company should consider hiring a growth marketing agency when internal teams lack the time, channel expertise, analytics support, or creative testing capacity needed to scale. It can also make sense when spend is rising but results are unclear. A good agency should help identify what to fix before asking for a larger budget.
