10 Performance Marketing Agencies That Actually Deliver Results

Last year, a mid-sized ecommerce brand fired its third marketing agency in eighteen months. Same story every time: big promises during the pitch, mediocre results three months later, and a lot of finger-pointing about “algorithm changes” and “market conditions.”

Sound familiar?

The performance marketing world is full of agencies that talk a great game. But when the invoices pile up and the results don’t match the projections, you’re left wondering if anyone in this industry actually knows what they’re doing.

Some agencies genuinely do. They’re just harder to find because they’re busy doing the work instead of winning marketing awards. We spent weeks cutting through the noise, verifying claims, and talking to marketers who’ve written the checks. Here are ten firms that have earned their reputations the hard way.

What Separates the Real Ones from the Pretenders

The agencies that deliver share a few traits. They show you specific numbers from real campaigns, not vague percentages without context. They keep clients for years, not months. They’ll tell you what they’re bad at, not just what they’re good at.

Keep these things in mind as you read through the list.

The 10 Best Performance Marketing Agencies in 2026

1. All Inclusive Marketing

Here’s a pattern that plays out everywhere: someone launches an affiliate program, signs up a handful of partners, and then… nothing. The program sits there generating pennies while everyone focuses on paid ads.

All Inclusive Marketing built its entire business around fixing this. Their team actively recruits partners, negotiates placements, monitors for fraud, and optimizes based on real data. It’s the unglamorous work that separates thriving affiliate programs from forgotten ones.

The results back it up. Clients consistently see double and triple-digit year-over-year growth. Bass Pro Shops calls working with them “hitting the jackpot.” With 50,000+ partners worldwide and 75+ years of combined team experience, they give brands instant access to a network that would take years to build alone.

2. Wpromote

Most agencies chase Fortune 500 clients. Wpromote made their name helping ambitious mid-market brands punch above their weight, competing against companies with ten times their budget.

Forrester named them a Leader in performance marketing, validating what their client list already shows. Whirlpool, TransUnion, Frontier Airlines chose Wpromote over flashier agencies because they wanted results over reputation.

Their proprietary Polaris platform pulls data from every channel into one view. If you’ve ever tried piecing together insights from Google, Meta, and Amazon dashboards manually, you know how valuable that is.

3. Tinuiti

Sometimes you need serious, enterprise-level scale.

Tinuiti is the largest independent performance marketing agency in the US, and they’ve used that size to build platform relationships smaller agencies can’t match. Google Premier Partner. Meta Business Partner. Amazon specialist. TikTok partner. Streaming deals with Netflix and Disney.

Those partnerships translate into early access to new ad formats and dedicated support teams. Their Bliss Point measurement technology tackles the attribution problem that drives every marketer crazy. If you’re spending seven figures on ads, Tinuiti belongs on your shortlist.

4. NoGood

When you’ve raised venture capital and have 18 months of runway, you don’t have time for slow-moving agencies.

NoGood was built for that environment. They cut their teeth on high-growth startups where every dollar matters. Test constantly, kill losing campaigns fast, iterate before competitors react. That approach worked well enough that Nike, TikTok, and P&G came calling.

Even with enterprise clients, they’ve kept the startup mentality. Their “performance branding” framework balances short-term conversions with long-term brand building in ways their case studies suggest actually work.

5. Power Digital

Every agency claims to be “data-driven.” Power Digital built the infrastructure to back it up.

Their Nova platform uses machine learning to surface growth opportunities humans might miss. They put specific numbers behind it: clients grow 2.6X faster than industry averages with 27% average year-over-year revenue increases.

What really sets them apart is tying marketing directly to revenue, not leads or traffic. When the CFO asks what ad spend actually produced, Power Digital clients have answers.

6. MuteSix

The best targeting in the world won’t save an ad nobody wants to watch.

MuteSix solved this by building a creative studio inside their performance agency. Their team produces ads designed for conversions, not awards shows. Media buyers and creative teams actually talk to each other, which is rarer than it should be.

The numbers validate the model: $1.2 billion+ in client revenue and 27.1 billion+ ad impressions. They’re particularly strong with e-commerce and DTC brands where creative quality directly impacts sales.

7. Acceleration Partners

Most affiliate agencies manage programs. Acceleration Partners built a global performance partnership machine.

They’re a six-time GPMA winner for “Best Affiliate and Partner Marketing Agency” with a team of 300+ specialists operating in 40+ countries. Clients include Target, Reebok, adidas, LinkedIn, and Crocs.

What sets them apart is treating partnerships as a full-funnel strategy, not just a last-click channel. They blend affiliate, influencer, content, and B2B partnerships into integrated programs that drive measurable revenue across the entire customer journey.

8. Disruptive Advertising

Healthcare and ecommerce require completely different approaches. Healthcare demands regulatory compliance and careful messaging. Ecommerce needs aggressive testing and split-second purchase decisions.

Most agencies pick one lane. Disruptive Advertising built genuine expertise in both. Client reviews tell a consistent story: 4-5X ROAS is typical, with some campaigns reaching even higher.

More importantly, they set realistic expectations upfront rather than overpromising and making excuses later. That honesty builds trust from day one.

9. Performics

As the original performance marketing agency, Performics wrote the playbook others now follow. Founded in 1998 and now part of Publicis Groupe, they operate in 41 countries with a relentless focus on converting consumer intent into revenue.

Forrester ranked them #1 in Search Marketing Agencies, and more than 25% of their revenue is tied directly to client ROI. That’s skin in the game most agencies won’t commit to.

Their expertise spans paid search, SEO, social, display, mobile, and affiliate. For enterprise brands needing global consistency with local execution, Performics delivers.

10. Brainlabs

Some marketers trust gut feelings. Others want to test everything and let data decide.

Brainlabs built their agency for the second group. Their entire culture revolves around experimentation, measurement, and statistical rigor. If you get excited about control groups and significance testing, you’ll feel at home here.

With 9 offices across North America, Europe, and Asia, they handle global campaigns needing consistency across markets. Their proprietary tech automates routine optimizations, freeing strategists for higher-level thinking.

Quick Reference Guide

Making Your Decision

Ask to speak with current clients in your industry. A fifteen-minute conversation with someone who’s worked with an agency for two years tells you more than any pitch deck.

Pay attention to how they handle sales. Do they ask thoughtful questions about your business, or jump straight into talking about themselves? The way they sell is usually the way they’ll serve.

Trust your gut about the people. If something feels off during the courtship phase, it rarely gets better after the contract is signed.

Choose carefully. Your marketing budget will thank you.
