12 Best B2B Performance Marketing Agencies in 2026

The B2B marketing landscape didn't just shift in the past two years, it reshuffled who gets budget and who doesn't. At Aimers, we've worked inside that shift with over 100 B2B SaaS companies, managing north of $30M in ad spend, and one pattern keeps repeating: boards want pipeline, not impressions.

This guide is for one specific moment: you've decided you need outside help with paid acquisition, maybe a dedicated SaaS PPC agency, and now you're working out who's actually good versus who's just good at selling themselves. 

Below: the agency-vs-in-house decision, selection criteria, our methodology, a comparison table, and all 12 agencies worth shortlisting in 2026.

B2B Performance Marketing Agency Comparison

How We Selected the Agencies

We reviewed each provider against six criteria:

1. B2B and SaaS relevance. The agency needed visible experience with B2B, SaaS, or technology buying journeys, not simply general performance-marketing claims.
2. Revenue-oriented measurement. We looked for evidence that the agency connects campaigns to qualified pipeline, opportunities, CAC, payback, or revenue rather than reporting only clicks and form fills.
3. Service-to-intent fit. Paid-media specialists, demand-generation firms, and outsourced teams were evaluated within their actual category.
4. Proof quality. Named clients, detailed case studies, defined processes, and current service pages carried more weight than directory badges or unsourced awards.
5. Conversion and measurement capability. Strong agencies should be able to diagnose landing pages, attribution, CRM feedback, and funnel leakage, not only buy media. A rigorous PPC account audit is a useful way to establish that baseline before committing to a retainer.
6. Fit transparency. We favored providers that state who they serve, what they do not do, or the investment and maturity they expect.

Performance Marketing vs. Outsourcing Your Marketing Function

Every provider on this list will tell you they can do it all. They can't, and the ones worth hiring will actually say so. The table below shows what each model owns and what it doesn't, before you sign anything.

An outsourced team isn't automatically better than an agency, just broader. If your ICP and sales process are stable, a focused partner creates more leverage with less overhead than hiring out the whole department.

12 Best B2B Performance Marketing Agencies

1. Aimers - Best for Integrated SaaS PPC, CRO, and Landing Pages

Aimers runs paid search, paid social, conversion rate optimization, landing pages, and analytics for SaaS and tech companies, nothing broader. The goal is simple: turn ad spend into qualified leads and revenue, then fix whatever's leaking conversions or muddying the data.

The agency has managed $30M+ in ad spend across 100+ SaaS and tech companies. Its fit guidance is blunt: budget at least $3,000/month per ad platform. Translation: come with an offer and an ICP, not just an idea.

Best fit:

SaaS and tech companies wanting one team across media, landing pages, CRO, and analytics. ‍

Pricing/engagement:

Best fit for companies with a marketing budget of + $3,000.

Pros:

SaaS specialization, connected media-to-conversion scope, senior team, clear minimum-spend guidance.

‍Cons:

No content, SEO, or PR arm; very early-stage companies may need GTM groundwork first. ‍

Aimers commentary:‍

We put ourselves first for this specific use case, not as a universal claim. If paid acquisition plus conversion is your bottleneck, we're built for it. If you need a fractional CMO or a content engine, look elsewhere on this list.

2. Hey Digital - Best for B2B SaaS Paid Media With Creative

Hey Digital focuses exclusively on B2B SaaS PPC. It manages Google, LinkedIn, Meta, Microsoft, and other paid channels, with in-house creative, landing pages, and CRM-connected reporting.

Best fit:

Post-PMF SaaS companies that already understand their market and are ready to invest consistently in paid acquisition.

‍Pricing/engagement:

Custom.

‍Pros:

Narrow B2B SaaS specialization; paid-media depth; in-house creative; clear non-fit guidance.

‍Cons:

Not designed to replace a full marketing team or own SEO, content, and email. Aimers commentary: A strong specialist shortlist should include Hey Digital when creative volume and paid social are central to the brief.

3. Webistry - Best for Creative-Led Paid Acquisition

Webistry works across paid media, creative, and landing pages, with visible experience in B2B and technology. Its appeal is the ability to test the ad-to-page experience rather than optimize media in isolation.

Best fit:

B2B technology companies with a proven offer that need more creative and conversion iteration.

‍Pricing/engagement:

Custom.

‍Pros:

Creative, media, and landing-page combination; practical testing focus.

‍Cons:

Buyers should verify current vertical depth, attribution scope, and how much senior attention is included. ‍

Aimers commentary:

Webistry is worth comparing when creative fatigue or weak message match, not channel selection, is depressing performance.

4. Holini - Best for a Senior-Only PPC and Analytics Model

Holini specializes in PPC and analytics for B2B technology categories including SaaS, cybersecurity, fintech, and cloud infrastructure. Its differentiator is a senior-only delivery model in which experienced specialists stay close to strategy and execution.

Best fit:

B2B tech teams already investing in acquisition that want hands-on specialist attention and measurement rigor.

‍Pricing/engagement:

Custom.

‍Pros:

B2B tech focus; senior delivery model; paid search, paid social, and analytics alignment. ‍

Cons:

Narrower than a full demand-generation agency; validate capacity and coverage for creative-heavy programs.

‍Aimers commentary:

Senior access is valuable, but ask for the actual workload and communication model rather than relying on the label alone.

5. 42 Agency - Best for Paid Media Connected to Marketing Operations

42 Agency positions itself around B2B demand generation and marketing operations for SaaS. Its scope can connect paid media with CRM infrastructure, content programs, and outbound, useful where campaign performance is limited by systems and handoffs.

Best fit:

B2B SaaS teams with a defined ICP that need acquisition and revenue operations to work together. ‍

Pricing/engagement:

Custom.

‍Pros:

Paid media and RevOps combination; public benchmarks and tools; broader pipeline view. ‍

Cons:

Wider scope introduces more dependencies; teams only seeking PPC execution may pay for complexity they do not need. ‍

Aimers commentary:

Put 42 Agency on the shortlist when CRM hygiene and marketing-to-sales flow are part of the actual problem.

6. Disruptive Advertising - Best for a Larger Multidisciplinary Paid-Media Partner

Disruptive Advertising provides paid search, paid social, creative, CRO, analytics, and lifecycle services across multiple industries. It brings more organizational scale than many specialist boutiques.

Best fit:

Companies that value capacity, process, and a broad paid-growth team over narrow SaaS specialization.

‍Pricing/engagement:

Custom.

‍Pros:

Wide channel coverage; conversion and creative capabilities; larger delivery organization.

‍Cons:

Not exclusively B2B SaaS; buyers should insist on a team with relevant long-cycle and CRM-to-revenue experience. ‍

Aimers commentary:

A larger agency can provide resilience and range, but vertical pattern recognition should still be tested during procurement.

7. Single Grain - Best for Broad Digital Growth Programs

Single Grain offers paid media, SEO, content, CRO, and other digital growth services for technology and enterprise clients. Its breadth makes it a potential fit when several digital workstreams must be coordinated.

Best fit:

Growth-stage or enterprise organizations looking beyond a single performance channel.

‍Pricing/engagement:

Custom.

‍Pros:

Broad scope; experience with recognizable technology brands; cross-channel capability.

‍Cons:

Buyers with a precise B2B SaaS PPC problem may prefer a more specialized team; confirm who owns strategy and execution. ‍

Aimers commentary:

‍Include Single Grain when breadth matters, but make the RFP specific enough to prevent a generic channel plan.

8. Directive - Best for Enterprise B2B Technology Programs

Directive is a large B2B and technology marketing agency built around its Customer Generation methodology. Its public positioning emphasizes customers, SQLs, and revenue rather than MQL volume, with services spanning paid media, organic search, content, lifecycle, and strategy.

Best fit:

Mid-market and enterprise B2B technology businesses with multiple channels, stakeholders, and meaningful budgets. ‍

Pricing/engagement:

Custom.

‍Pros:

Broad delivery capacity; strong B2B tech positioning; suitable for complex programs. Cons: The scale and breadth may be excessive for a small company that only needs one paid channel; buyers should confirm who will work on the account day to day.

‍Aimers commentary:

Directive belongs on an enterprise shortlist when coordination across channels matters more than specialist intimacy.

9. Powered by Search - Best for Established SaaS Demand Generation

Powered by Search serves B2B SaaS and technology companies through paid media and broader demand-generation capabilities. Its paid programs include Google, LinkedIn, and Facebook, supported by forecasting, messaging, and conversion work.

Best fit:

Post-PMF SaaS companies seeking a strategic, self-managing partner across more than campaign execution.

‍Pricing/engagement:

The agency publicly describes good-fit clients as ready to commit at least $7,500 per month to marketing for at least a year; confirm the current agency fee and media budget separately. ‍

Pros:

SaaS specialization; revenue forecasting; senior-consultant positioning; paid and organic breadth. ‍

Cons:

A long commitment and wide scope may not suit teams running a contained test. Aimers commentary: The forecasting orientation is useful for buyers who need to defend budget internally, but validate assumptions against your own sales data.

10. Refine Labs - Best for Reworking B2B Demand Generation

Refine Labs combines demand strategy, paid media, creative, and measurement for B2B technology companies. It publicly targets Series B and later organizations and frames its work around brand, demand, and expansion rather than isolated lead-generation campaigns.

Best fit:

Established B2B tech companies with an internal marketing function and a strategic demand problem.

‍Pricing/engagement:

Its six-week diagnostic is publicly listed from $35,000; ongoing engagements are custom. ‍

Pros:

Clear maturity requirements; strong strategic point of view; senior roles remain involved in execution. ‍

Cons:

The investment and operating model are unlikely to suit early-stage teams or a narrow channel brief. ‍

Aimers commentary:

Refine Labs is most compelling when leadership wants to change how demand is created and measured, not simply lower Google Ads CPA next month.

11. NoGood - Best for High-Velocity Growth Experimentation

NoGood is a growth-marketing agency serving SaaS, technology, startups, and larger brands. Its model emphasizes rapid experimentation across paid media, creative, conversion, SEO, content, and lifecycle channels.

Best fit:

Funded companies with enough traffic, budget, and internal speed to support a high testing cadence. ‍

Pricing/engagement:

Custom.

‍Pros:

Cross-functional growth scope; experimentation culture; suitable for companies exploring several growth levers. ‍

Cons:

Buyers seeking a pure B2B demand-capture specialist should confirm account-team depth in their exact sales motion. ‍

Aimers commentary:

Experimentation only creates value when the company can implement and evaluate tests quickly. Ask how the agency handles low-volume enterprise funnels.

12. Kalungi - Best for Outsourcing B2B SaaS Marketing

Kalungi is the broadest operating model in this guide. It offers fractional marketing leadership, GTM strategy, paid media, content, marketing operations, design, and other execution through tiered programs.

Best fit:

Post-PMF B2B SaaS companies that lack marketing leadership or want to outsource most of the function. ‍

Pricing/engagement:

Kalungi publicly lists full-service work at $50,000+ per month and aims that offer at roughly $5M-$50M ARR companies. Other support levels are custom.

‍Pros:

Leadership and execution in one model; extensive SaaS focus; clear fit and pricing for full service. ‍

Cons:

Expensive and broader than a conventional performance agency; requires significant organizational access and alignment. ‍

Aimers commentary:

‍ This is the clearest agency-versus-outsourcing decision in the list. Choose Kalungi when you need the department, not merely better campaigns.

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:

• Execute what you tell them to
• Act as order-takers

Full-service partners:

• Challenge your assumptions
• Recommend strategic changes
• 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, spotting 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 an audit for a potential client reveals the real problem isn't the ads at all:

• Landing pages converting at 0.8% when they should be at 3–4%
• Analytics setups so broken that decisions are being made on incomplete data

For the bigger picture, see Aimers' B2B demand generation guide for SaaS.

For teams prepping the channel brief, Aimers' guide to PPC lead generation for SaaS covers how intent, message, offer, and follow-up fit together. And before signing anything, check your notes against the warning signs of a bad performance marketing agency.

Final Recommendation

Start with the business constraint, then choose the agency category.

If paid acquisition is already strategically valid but inefficient, shortlist two or three specialists with SaaS experience, conversion capability, and CRM-level measurement. If the growth problem spans positioning, demand creation, content, RevOps, and leadership, compare broader demand-generation or outsourced-team models. If product-market fit or unit economics are unresolved, do not use paid media to hide that uncertainty.

At Aimers, our lane is clear: paid search, paid social, CRO, landing pages, and analytics for SaaS and tech companies. We aim to improve the complete path from click to qualified pipeline without pretending to be every type of agency.
