15 Los Angeles Performance Marketing Agencies Scaling E-commerce to $100M+

In the cutthroat world of Los Angeles e-commerce, hitting the $100 million revenue mark isn't just about having a great product, it’s about having a growth engine that never sleeps. As we move into 2026, the digital commerce landscape has shifted from simple social media ads to a complex, AI-integrated ecosystem where retention is just as critical as acquisition. To reach nine figures, you need more than an agency, you need a performance partner that understands the high-velocity, high-stakes nature of the LA market and can manage massive capital with surgical precision.

I’m Riten, founder of Fueler, a skills-first portfolio platform that connects talented individuals with companies through assignments, portfolios, and projects, not just resumes/CVs. Think Dribbble/Behance for work samples + AngelList for hiring infrastructure.

1. Promote: The Challenger Brand Architects

Wpromote is a dominant force headquartered in El Segundo, specifically known for helping "Challenger Brands" steal market share from established industry giants. They don't just manage budgets, they rewire how brands think about data by using their proprietary "Polaris" tech to unify every marketing signal. For a brand aiming for $100M, Wpromote provides the enterprise-level sophistication needed to manage massive scale without losing the creative agility that made the startup successful in the first place.

• Polaris Intelligence Platform Integration: This is their proprietary data engine that unifies all marketing signals into a single source of truth, allowing them to see the cross-channel impact of every dollar spent. It eliminates data silos between search and social, ensuring that your Google Ads and Meta campaigns are working in total harmony rather than competing for the same customer.
• Predictive Lifetime Value (LTV) Modeling: They leverage advanced AI to identify which customers will be worth the most to your business over the next 24 months based on early purchase behavior. By focusing your acquisition budget on these high-value individuals, they ensure your path to $100M is built on a foundation of profitable, repeat buyers rather than one-time shoppers.
• Full-Funnel Creative Analytics: Their in-house creative team works directly with media buyers to engineer ads based on performance data rather than just "vibes." They analyze granular elements like visual hooks and calls-to-action to produce "thumb-stopping" content that actually drives a positive Return on Ad Spend (ROAS) across fragmented platforms.
• Agile Budget Fluidity & Profit Bidding: They pioneered a "Profit-First" bidding model where budgets are shifted in real-time to the most profitable channel based on daily fluctuations. If YouTube is driving higher quality leads on a Tuesday afternoon, their system automatically reallocates spend from underperforming channels to maximize that specific window of revenue opportunity.
• Omnichannel Marketplace Dominance: Beyond just your standalone website, they are experts at scaling brand presence on Amazon and Walmart.com. For a $100M brand, being "omnichannel" is mandatory, and Wpromote ensures your brand is the category leader across every digital shelf by optimizing listings for both search visibility and conversion velocity.

Why it matters

Scaling to $100M requires a fundamental shift from "marketing" to "business intelligence." Wpromote provides the technical infrastructure and senior-level strategy that allows founders to stop guessing and start engineering their growth, making it a perfect fit for VC-backed or private-equity brands.

2. Common Thread Collective: The DTC Growth Guides

Based in Santa Ana and serving the greater LA area, Common Thread Collective (CTC) is legendary in the Direct-to-Consumer space. They are the creators of the "Admission" community and the Statlas data platform, specializing in the "messy middle" of growth. They take brands from $10M to $100M by focusing on the "Four Levers of E-commerce," Acquisition, Conversion, Retention, and Unit Economics, ensuring that the business stays healthy while it grows.

• Statlas Benchmarking & Analytics: This proprietary tool allows them to compare your brand's performance against thousands of other DTC companies in real-time. This level of transparency allows them to see exactly where your "leaks" are, whether your Customer Acquisition Cost is too high for your category or your repeat purchase rate is lagging behind industry leaders.
• Forensic Financial Modeling for Growth: They treat your Profit and Loss statement like a map for future success. Before spending a single dime on ads, they build a financial model that shows exactly how much you can afford to pay for a customer while still maintaining the margins needed to scale to a nine-figure exit.
• Retention-First Strategy & Lifecycle Flows: CTC understands that you cannot buy your way to $100M with new customers alone because the math eventually breaks. They build sophisticated email and SMS "profit engines" that nurture existing customers, significantly increasing the LTV-to-CAC ratio through personalized post-purchase journeys and loyalty triggers.
• Creative Strategy & High-Volume Production: They produce high-volume, performance-driven content designed specifically for the "Lo-Fi" TikTok and Reels era. Their ads don't look like expensive commercials; they look like the organic content your customers are already consuming, which leads to higher engagement rates and lower costs-per-click.
• The "Growth Team" Pod Model: You don't just get a random account manager; you get a dedicated "pod" consisting of a strategist, a media buyer, and a creative director. This ensures that every part of your growth engine is talking to the other, creating a feedback loop where creativity informs buying and buying informs creativity.

Why it matters

CTC is obsessed with the math of growth, which is vital for brands that need to be profitable. For founders who are experts at product but need a "CFO of Marketing," CTC provides the data-driven discipline and financial rigor required to scale a brand to massive enterprise value.

3. KlientBoost: The ROI-Obsessed Powerhouse

With a major presence in Los Angeles, KlientBoost has become one of the most reviewed and highest-rated performance agencies in the world. They are famous for their "no-fluff" approach and their aggressive focus on Conversion Rate Optimization (CRO). They believe that if your website doesn't convert, no amount of ad spend will get you to $100M, so they fix the funnel first before pouring gasoline on the fire.

• The "Boostbar" Methodology for Testing: This is their internal system for constant, relentless A/B testing across every touchpoint. They run hundreds of experiments on landing pages and ad copy simultaneously, ensuring that your acquisition funnel is getting more efficient every single day rather than stagnating with old creative.
• Deep Vertical Performance Specialization: They have specialized teams for e-commerce, SaaS, and lead generation. This means the person managing your account has deep, niche experience in exactly what makes a consumer click "Buy Now" in your specific industry, allowing them to skip the learning phase and get straight to results.
• Custom Real-Time Reporting Dashboards: They provide 100% transparent dashboards that show exactly where every dollar of your budget is going. You can see the direct correlation between an ad tweak and a revenue spike in real-time, which is essential for high-velocity scaling where decisions need to be made fast.
• Landing Page Design & Technical Development: Unlike many agencies that just "advise" on changes, KlientBoost actually builds the pages for you. They create high-speed, high-converting custom landing pages that are optimized for mobile-first shoppers and designed to beat your current "control" page in a head-to-head test.
• Holistic Search-to-Social Loop: They manage the entire digital journey from the first social impression to the final search click. By using search data to inform social targeting and social creative to inspire search headlines, they create a unified brand front that captures demand wherever your customers spend their time.

Kobe Digital is a Los Angeles-based agency that views marketing as a combination of engineering and art. They are structured into three distinct divisions, Media, Design, and Code, allowing them to handle the entire "Growth Stack" for an e-commerce brand. This integrated approach is crucial for brands scaling to $100M because it ensures that the website tech, the ad creative, and the media buying are all perfectly aligned.

• Unified Growth Ecosystem & Communication: Because they have designers, developers, and media buyers under one roof, they can pivot and solve problems incredibly fast. If a developer finds a "bug" in the checkout flow, the media buyer is notified instantly to pause ads, saving thousands of dollars in potentially wasted ad spend.
• High-Production Cinematic Creative Studio: They don't just make "ads," they make brand experiences that build long-term equity. Their creative division produces cinematic video content that builds the brand's "prestige" while still being strictly optimized for performance metrics like click-through rate and conversion value.
• Technical SEO & Site Speed Engineering: For a $100M brand, a one-second delay in load time can cost millions in lost sales. Kobe's "Code" division ensures your Shopify Plus or BigCommerce store is lightning fast and optimized for the latest Google search algorithms to maximize organic reach alongside paid efforts.
• AI-Driven Audience Discovery Models: They use machine learning to find "hidden" audiences that your competitors are completely missing. By analyzing billions of data points, they can predict who is about to enter a "buying window" for your product and serve them an ad before they even search for a competitor.
• Full-Funnel Lifecycle Marketing Management: They manage the user journey from the very first "awareness" ad all the way through to long-term brand advocacy. This "closed-loop" marketing approach ensures that every customer touchpoint is optimized for the highest possible lifetime value and repeat purchase rate.

5. Melleka Marketing: The Strategic Growth Partners

Melleka Marketing is a boutique Los Angeles agency that specializes in high-touch, senior-led growth strategies. They are the antithesis of the "big agency" model where you get passed off to a junior account manager. At Melleka, you work directly with experts who have managed nine-figure budgets for some of the world’s biggest brands and know exactly where the "landmines" are in the scaling process.

• Senior-Level Execution & Oversight: You are never passed off to a trainee or a junior intern. The people strategizing your account are the ones actually clicking the buttons in the ad manager, ensuring that high-level business strategy isn't lost in the technical execution of the campaigns.
• Omnichannel Growth Strategy Expansion: They look far beyond the standard Meta and Google duo to find growth. They help brands expand into Pinterest, YouTube, and Programmatic advertising to find "cheaper" pockets of high-intent traffic that your competitors are likely ignoring or underutilizing.
• LTV and Retention Journey Architecture: They build deep, automated "post-purchase" journeys. By analyzing granular customer behavior, they create automated flows that bring people back for their second and third purchases, which is the absolute key to sustainable and profitable nine-figure growth.
• Scientific Creative Testing Framework: They employ a rigorous "Scientific Method" for creative testing. They test specific hooks, visual styles, and calls-to-action in small, controlled batches before scaling the "winners" with a massive budget behind them to ensure a high probability of success.
• Performance-Based Alignment: They often align their financial incentives with your business's growth. Their success is tied directly to your scaling, ensuring they are just as motivated as you are to find that extra 1% of efficiency in every single campaign they run for you.

This drives massive amounts of organic traffic that scales for "free" over time, providing a profitable cushion for paid media.

This allows them to automatically identify and fix friction points in the customer journey that are causing users to drop off before completing a purchase.

While they serve the broader LA market, Disruptive Advertising is famous for their forensic "Audits" that uncover massive amounts of wasted ad spend. They believe that most brands are wasting at least 50% of their budget on "garbage" traffic that will never convert. Their mission is to find those inefficiencies and reallocate that money into high-ROAS growth opportunities.

• Forensic Ad Account Audits: They start every relationship with a deep dive into your historical data to find exactly where you are overpaying for clicks. This initial "clean up" often results in an immediate jump in ROAS before they even start launching new creative or campaigns.
• Creative Disruption Strategy: They believe in ads that "break the pattern" of the user's feed. By creating content that stands out from the boring, standard e-commerce templates, they drive much higher engagement rates and lower your overall costs-per-acquisition across social platforms.
• Transparent Multi-Channel Attribution: They use advanced third-party tracking to show you exactly how your social ads are influencing your search sales. This solves the "blindness" of platform-specific reporting, allowing you to see the true impact of your marketing spend across the entire funnel.
• Aggressive Weekly Retesting Cycles: They never assume a campaign is "done" just because it’s working. They are constantly retesting old "winners" against new ideas and formats to ensure they aren't missing out on new market trends or shifts in consumer behavior.
• Verified ROAS & Profit Focus: They are one of the few agencies that will publicly stand by their ROAS figures and case studies. They focus strictly on the metrics that impact your bank account, providing clear, no-nonsense reporting on profit and loss for every campaign.

Final Thoughts

Scaling an e-commerce brand to $100M in 2026 is a feat of both engineering and creativity. The Los Angeles agencies on this list represent the elite of the performance world, each bringing a unique set of tools to the table from Wpromote’s enterprise data systems to Scube’s hyper-specialized search expertise. The key to hitting nine figures is finding the partner that aligns with your specific technical needs and brand values. With the right team in your corner, that $100M target isn't just a dream, it's a measurable, engineerable destination.

FAQs

1. What is the average ROAS for an e-commerce brand scaling to $100M?

While it varies by industry, brands at this scale typically aim for a "Blended ROAS" (total revenue divided by total ad spend) of 3x to 5x. However, at the $100M mark, agencies focus more on "Contribution Margin" and "Incremental ROAS" to ensure that every new dollar spent is actually generating additional profit rather than just cannibalizing organic sales.

2. How much should a $10M brand spend on an agency to reach $100M?

Most agencies on this list charge a monthly retainer starting at $10,000, plus a performance fee of 1% to 3% of total revenue or 10% to 15% of ad spend. For a brand scaling aggressively, you should expect to invest significantly in both the agency's expertise and the creative production needed to keep the ad accounts fresh.

3. Do these agencies handle international e-commerce expansion?

Yes, most enterprise-level agencies like Wpromote, Digital Silk, and Thrive have extensive experience in global scaling. They help with localized ad copy, multi-currency tracking, and international SEO to ensure your brand's message resonates in markets like Europe, Asia, and the Middle East while maintaining a high ROAS.

4. How does AI impact performance marketing in 2026?

In 2026, AI will be used for real-time bidding, automated creative testing, and predictive customer modeling. Top agencies use AI to analyze billions of data points to find "buying signals" that humans would miss, allowing them to target customers more accurately and reduce wasted ad spend by up to 30%.

5. What is "First-Party Data" and why is it important for LA agencies?

With the decline of third-party cookies, "First-Party Data" (information you collect directly from your customers, like email and purchase history) is the most valuable asset you own. LA agencies use this data to build "Lookalike" audiences and personalized retention flows that don't rely on platform tracking, ensuring your marketing remains effective in a privacy-first world.
