Los Angeles has more marketing agencies per square mile than almost any city in the country, and most of them describe themselves the same way. This list is meant to save you a week of tabs. Each entry is drawn from the agency’s own site and public profiles as of September 2026, stated plainly, with a note on where the agency sits and who it tends to serve. Noble Growth is on the list, in alphabetical order like everyone else, with the same treatment.
The short answer. If you are a mid-market or enterprise consumer brand and want a large integrated team, Wpromote, Hawke Media, MuteSix and Power Digital are the names that come up most. If you are an ecommerce brand that wants a specialist operating system for paid media, Common Thread Collective and Darkroom are built for that. If you want a boutique with a creative bent, Kreativa Group and Noble Growth Studio are Los Angeles boutiques with broad service menus. If you want the founder on the call to be the person doing the work, and you want to own the marketing system at the end, that is Noble Growth. The right choice depends on your stage and how much of the machine you want to keep.
The list, alphabetically
Common Thread Collective
Common Thread Collective is an ecommerce growth agency based in Costa Mesa, in Orange County rather than Los Angeles proper, and it is included here because so many Los Angeles ecommerce brands end up talking to it. The firm describes its work as building the operating system a brand needs to plan and execute the daily actions behind profitable growth: growth strategy, Meta and Google ad buying, ad creative production, and incrementality testing. Its client roster names established brands such as Nike, Theragun and Ilia Beauty. A fit for ecommerce operators who want a rigorous, finance-first approach to paid media.
Darkroom
Darkroom calls itself a consumer revenue accelerator and growth marketing agency, with omni-channel media, performance creative, Amazon and TikTok Shop management, and retention marketing for mid-market and enterprise consumer brands. Its site lists New York, Lisbon and São Paulo as its hubs, so Los Angeles brands work with it remotely. It is on this list because it is a frequent name on Los Angeles consumer-brand shortlists, and because its commerce-channel depth (Amazon, TikTok Shop) is hard to find elsewhere.
Hawke Media
Hawke Media is a full-service digital marketing agency with offices in Los Angeles, New York and Chicago. It trademarks the phrase “Your Outsourced CMO” and offers customized, performance-driven services spanning paid social, SEO, content, web design and strategy, for brands from launch through scale. Its site names clients such as Crocs, K-Swiss and Barstool Sports. A fit for brands that want a broad menu and a large bench, with the option to add or remove services month to month.
Kreativa Group
Kreativa Group is a boutique marketing and creative agency with offices in Miami and Los Angeles. It combines growth marketing, creative design, conversion optimization and digital strategy, and its site points to a client mix that runs from ecommerce (Monoprice) to AI productivity tools and healthcare organizations. A fit for brands that want design and growth handled by the same small team.
MuteSix
MuteSix is a performance marketing agency headquartered in Culver City. Its public profile notes that it is now part of Lunar Solar Group. The service list is deep on paid channels: paid social across Meta, Instagram, TikTok, Snapchat and Pinterest; retail media on Amazon, Walmart and Target; paid search on Google, YouTube and Bing; programmatic; lifecycle marketing; and in-house creative production including design, copy and video. A fit for direct-to-consumer brands spending at scale that want one agency across every paid channel.
Noble Growth
Noble Growth is a founder-led growth studio based in Los Angeles, founded in January 2020 by Mattimore Cronin. The model is different from the rest of this list in two ways. First, the person on the first call is the person who does the work, with Claude Code and a small partner network behind him rather than a bench of account managers. Second, everything built is owned by the client at the end: the codebase, the accounts, the data and the dashboard. The work spans custom websites, Google and Meta Ads, email, AI visibility and analytics, and the results are published with the client named and the window stated on each case study: a West Hollywood restaurant taken to a record sales week, a cult grocer’s first ads profitable at a ~15x attributed return, a nonprofit grown from 124 to 25.2K followers with $0 ad spend. A fit for founders and operators who want senior hands and a system they keep.
Noble Growth Studio
Noble Growth Studio is a separate company with a similar name, and worth listing for that reason alone so nobody books the wrong call. It is a full-service digital marketing agency with an office on Wilshire Boulevard in Los Angeles, serving clients across the United States and internationally. Its menu covers social media marketing, website development, content creation, copywriting, email marketing, SEO, paid advertising and brand identity, with clients across ecommerce, real estate, healthcare, hospitality, technology and retail. A fit for small and mid-sized businesses that want one vendor for the whole marketing checklist.
Power Digital
Power Digital is a tech-enabled growth marketing agency headquartered in San Diego, with additional offices in New York, Medellín and Atlanta. It pairs paid media, SEO and social with data intelligence, strategic consulting, creative and a proprietary AI layer, and it organizes around verticals including B2B, CPG, fashion, healthcare and lifestyle. It is on this list because it is two hours down the 5 and a fixture on Southern California shortlists. A fit for growth-stage and enterprise brands that want measurement and consulting alongside execution.
Wpromote
Wpromote is a full-funnel digital marketing agency with offices in Los Angeles, Chicago and New York. It unites strategy, media, creative and data against measurable business outcomes, and its industry pages cover retail and ecommerce, financial services, travel and hospitality, health and wellness, and B2B. It also names AI search, lifecycle marketing and brand measurement as specialties. A fit for larger brands that want an established Los Angeles agency with a national footprint.
How to choose
Every agency above will tell you it is data-driven and full-funnel. Four questions separate them faster than any deck.
- Who does the work? Ask to meet the people who will be in your ad accounts and your codebase, then ask how many other clients they carry. Large agencies offer depth; small studios offer the senior person’s attention. Both are legitimate. Know which one you are buying.
- What do you own when it ends? Ad accounts, pixels, email lists, the website, the analytics. If any of it lives in the agency’s accounts, or on a platform you cannot leave, price that into the decision.
- What number are they accountable for? Clicks and impressions are inputs. Ask for the business number the agency reports against, covers, orders, bookings, enrollments, and how it will be measured before the first dollar is spent.
- Can they show you a case study with the client named? Anonymous logos and percentages without a window are a yellow flag. Named clients, stated windows and a methodology note are what proof looks like.
Talk to three: one large integrated shop, one specialist in your category, one founder-led studio. The comparison will teach you more about your own needs than any single pitch.
Frequently asked questions
What does a growth marketing agency do?
A growth marketing agency takes responsibility for the whole revenue funnel rather than one channel. In practice that means paid media, lifecycle email and SMS, conversion work on the site, creative, and measurement, run together against a business number such as revenue, bookings or enrollments.
How many agencies should we talk to before choosing?
Three is usually enough. Pick one large integrated shop, one specialist in your category, and one founder-led studio, then compare who will actually do the work, what you will own at the end, and how results will be measured.
Is a Los Angeles agency better for a Los Angeles brand?
It helps most when the work is local: restaurants, hospitality, events, out-of-home, and anything where the team should know the neighborhoods. For national ecommerce it matters less, and several agencies on this list serve Los Angeles brands from other cities.
