12 Best B2B Performance Marketing Agencies

The B2B marketing landscape has changed more in the past two years than in the previous decade combined.

We've been in the trenches at Aimers with over 100 B2B SaaS companies, managing north of $30M in ad spend. The old playbook doesn't cut it anymore. Brand awareness campaigns without measurable ROI, content marketing without clear attribution, social media marketing "engagement" that doesn't translate to pipeline, companies are done with it.

Why B2B Companies Are Shifting to Performance Marketing Agencies

"We need to know what's working. We need every dollar to be accountable."

That's what we keep hearing from SaaS founders and CMOs. The days of spending six figures on brand campaigns and hoping something sticks? Over.

Boards want metrics. Investors want proof. Your job depends on showing real, measureable growth. Traditional digital marketing agencies talk about impressions and reach, performance marketing agencies talk about cost per acquisition, customer lifetime value, and return on ad spend.

We've worked with companies like Mixpanel, ShipBob, and Originality.AI, brands that don't have unlimited marketing budgets to waste. They need campaigns that drive qualified leads today, close deals this quarter, and scale predictably next year. If you're curious what separates performance marketing agencies that actually deliver from the ones that just talk a good game, we wrote about the red flags to watch out for.

Performance marketing agencies are built differently. We're accountable for outcomes, not outputs.We don't care if your LinkedIn post got 10,000 impressions if it didn't generate a single SQL.

What Separates Best B2B Marketing Agencies from the Rest

Performance Marketing vs. Traditional Digital Marketing

Traditional agencies will build you a beautiful website, create thoughtful content, and run marketing campaigns across channels. But they fall short for most B2B SaaS companies because they're not obsessed with your unit economics.

Performance marketing agencies live and breathe metrics that actually matter. What's your CAC? What's your payback period? Which marketing channels are driving customers with the highest LTV?

At Aimers, we've helped Originality.AI acheive a 210% conversion rate increase and drove 164% more qualified leads for Mixpanel. Not by running pretty campaigns, by relentlessly optimizing every step of the funnel. You can see more detailed results in our case studies.

Full-Service B2B Marketing Agency Capabilities That Matter

The best B2B marketing agencies in 2025 aren't one-trick ponies. You need to understand how paid search, paid social, conversion optimization, landing page design, and analytics all work together.

We see this constantly. A company hires a specialist agency to run their Google Ads. The campaigns perform well, but the landing pages convert terribly. Or the landing pages are great, but attribution is broken.

Even the best ad campaign can't save a broken landing page or bad analytics. Full-service digital marketing agencies that specialize in B2B have figured out that it's all connected. Your ad copy needs to match your landing page. Your landing page needs to match your sales messaging. Your analytics need to tie it all back to closed revenue.

2. Metadata.io

If you're drowning in campaign management across multiple platforms, Metadata is worth looking at. They've built automation technology specifically for B2B demand generation.

Their platform uses AI to optimize campaigns across Google, LinkedIn, and Facebook. Unlike most "AI-powered" solutions, theirs is built specifically for complex B2B sales cycles. They understand that a click isn't a conversion, and a lead isn't always a qualified opportunity.

What makes Metadata interesting is how they handle audience targeting across platforms. Their platform syncs targeting across channels automatically. When someone engages with your content on LinkedIn, that signal influences how they're targeted across other platforms.

3. Directive Consulting

Directive has built a strong reputation as a performance marketing agency specializing in B2B SaaS and enterprise tech companies. They're particularly good at search marketing, both paid and organic.

Their approach combines traditional performance channels with content marketing in ways that actually drive pipeline. Strategic content designed to rank for high-intent keywords your buyers are actually searching.

4. Altitude Marketing

Altitude Marketing has developed deep expertise in complex B2B marketing campaigns. They work primarily with enterprise companies and mid-market B2B tech firms that have longer sales cycles and multiple stakeholders.

What Altitude Marketing does well is understanding the messy reality of enterprise sales. When you're selling to companies with 8-12 decision-makers involved, your marketing can't be simplistic. You need different messaging for technical evaluators, economic buyers, and end users. Research from Harvard Business Review shows that the average B2B purchase now involves 6-10 decision-makers, making coordinated marketing more critical than ever.

They've built expertise in account-based marketing, demand generation, and sales enablement specifically for complex B2B environments.

5. Iron Horse

Iron Horse positions itself as a growth marketing agency for B2B tech companies. They've worked with brands including Adobe, Gainsight, and VMware.

Their strength is in revenue operations and marketing and sales coordination. They help build the infrastructure that turns marketing activities into predictable revenue, marketing automation, lead scoring, opportunity management, and attribution modeling.

6. Refine Labs

Chris Walker's agency has made a splash with a somewhat controversial approach. Brand marketing that's still performance-driven.

Refine Labs argues that most B2B demand generation is too focused on bottom-funnel conversions and not enough on building category awareness with your target accounts. But unlike traditional brand agencies, they still measure everything and tie it back to pipeline influence.

Their approach works particularly well for B2B SaaS companies in competitive categories where differentiation matters.

7. Webistry

Webistry specializes in paid advertising for B2B tech companies, with particular strength in LinkedIn and Google Ads.

What we appreciate about Webistry is their testing methodology. They're constantly running experiments to find incrementally better approaches, slightly different ad copy, alternative audience segments, new bidding strategies.

For growth-stage SaaS companies that need to scale quickly without destroying unit economics, that test-and-learn approach is essential.

8. Belkins

Belkins has carved out a niche in B2B lead generation and appointment setting. Sounds old-school, but it's actually still incredibly effective when done right.

They combine cold outreach with paid advertising and content syndication to generate qualified meetings for B2B tech companies. Their approach works well for companies with complex solutions that require sales conversations to close. If you're looking for more B2B lead generation strategies, we've compiled 15 proven tactics that actually work for SaaS companies.

9. SmartBug Media

SmartBug is a full-service digital marketing agency that specializes in inbound marketing and marketing automation for B2B companies. They're a HubSpot partner, which means they're particularly strong if your tech stack is built around HubSpot.

Their content marketing approach is more sophisticated than most agencies. They build comprehensive content strategies designed to rank in search, generate qualified traffic, and convert visitors into MQLs. According to HubSpot's State of Marketing report, companies that prioritize content marketing see 3x higher lead generation rates than those that don't.

10. Disruptive Advertising

Disruptive Advertising is a performance marketing agency focused on paid acquisition for B2B SaaS. They're known for their data-driven approach and ability to scale campaigns while maintaining efficiency.

They specialize in Google Ads, LinkedIn advertising, and Facebook campaigns, running performance-driven programs that integrate tightly with sales processes. Their team brings deep experience in conversion optimization and testing methodologies.

11. Single Grain

Single Grain offers a range of digital marketing services, but their strength is in paid acquisition and conversion optimization for B2B tech companies.

They've worked with companies like Uber, Amazon, and Salesforce. That gives them experience handling large-scale campaigns with serious budgets. But they also work with smaller SaaS companies that are just starting to scale paid channels.

12. Blend

Blend focuses exclusively on B2B marketing for technology companies. They offer both strategy consulting and execution across paid media, content marketing, and marketing operations.

Their approach is particularly well-suited for mid-market B2B companies that need strategic guidance as much as campaign execution.

How Top B2B Marketing Agencies Drive Measurable Performance

The best performance marketing agencies don't optimize campaigns in isolation. They think about the entire system, how channels work together, how marketing influences sales, how every dollar spent contributes to revenue growth.

At Aimers, we've developed frameworks for measuring what actually matters:

• Cost per marketing-qualified lead
• Marketing-influenced pipeline
• Conversion rates by channel and campaign
• Customer acquisition cost
• Payback period

Generating tons of leads but they're not converting to opportunities? There's a problem with lead quality. CAC is too high relative to LTV? You need to either improve efficiency or adjust your target customer profile.

Marketing rarely fails because of low traffic. The real leak is often deeper in the funnel.Maybe your landing page messaging doesn't match your ad promises. Maybe your demo request form is too long. These are the issues that actually kill performance.

Choosing the Right B2B Marketing Agency for Your Business

There's a real difference between hiring a digital marketing agency that runs campaigns and partnering with a full-service B2B marketing agency that acts like an extension of your team.

Campaign-focused agencies will execute what you tell them to. They're order-takers. Full-service partners will challenge your assumptions, recommend strategic changes, and take ownership of outcomes.

At Aimers, when we work with clients like Orion Labs or Uppbeat, we're not just running their Google Ads. We're looking at their entire go-to-market strategy, identifying opportunities, and taking responsibility for driving actual growth. If you're considering hiring a SaaS marketing agency, we've written the ultimate guide to making the right choice.

Sometimes we'll run an audit for a potential client and discover their biggest problem isn't their ads at all, it's their landing pages converting at 0.8% when they should be at 3-4%. Or their analytics setup is so broken they're making decisions based on incomplete data.

Ready to Scale Your B2B SaaS with the Right Marketing Partner?

We've spent over 10 years building Aimers into exactly the kind of performance marketing agency we'd want to work with. We're obsessed with metrics that matter. We're deeply experienced in B2B SaaS. And we're accountable for driving real results.
