12 Content Marketing Agencies With a History of B2B Success

If you’ve been on LinkedIn lately, you know it’s full of long-winded posts by professionals claiming to be B2B marketing gurus. Maybe they are, maybe they aren’t. How do you know who to really trust?

If you’re anything like us, you’re focused on results. That’s why we’ve put together this list of B2B content marketing agencies that have a proven track record of delivering value for their customers.

Why are we telling you about our competitors? Because we know each of these companies is an ideal fit for different clients, and we genuinely want you to see success, even if it’s not with us.

What Makes B2B Content Marketing Different

B2B content marketing requires specialized expertise that sets it apart from consumer-focused approaches. B2B audiences demand deeper subject matter expertise, while longer sales cycles require educational content across multiple touchpoints. Multiple stakeholders within buying committees need different content types at each stage of their evaluation, and success gets measured by pipeline contribution and revenue impact rather than just engagement metrics like keyword rankings.

Key differences between B2B and B2C content marketing:

• Buyer Journey: 6-18 month cycles with 5-11 decision makers vs. individual B2C purchases
• Content Depth: High-quality content, think whitepapers, product-led, and case studies vs. lifestyle content or another top of funnel blog
• Success Metrics: Pipeline contribution and ARR vs. immediate conversions or more traffic
• Distribution Channels: LinkedIn, sales, email marketing, industry publications, and webinars vs. social media

How To Choose The Right B2B Marketing Content Agency

Finding the right B2B content marketing agency requires a practical framework that aligns with your business goals and growth objectives. Agencies that deliver results understand your audience and their buying habits, can demonstrate measurable ROI, offer flexible engagement models, bring industry-specific knowledge, and prioritize communication and alignment with your team.

Expertise In Complex Buyer Journeys

B2B content agencies demonstrate fluency in multi-stakeholder buying processes. Ask agencies how they plan to map content to different B2B buyers — technical evaluators need implementation details, while executives care about strategic outcomes and ROI projections. The best agencies understand how to transition prospects from awareness content that educates about the problems they’re to decision content that reduces purchase friction.

Questions to evaluate buyer journey expertise:

• How do you identify and create content for different buying committee members?
• Can you share examples of content strategies that addressed both technical and executive audiences?
• How do you support account-based marketing initiatives with targeted content?
• What's your approach to nurturing prospects through extended sales cycles?

Track Record Of Measurable ROI

Results matter more than promises. Request case studies with specific business metrics: pipeline generated, conversion rates, customer acquisition costs, and revenue attribution. Verify claimed results by speaking with references who can confirm the agency's impact on their business outcomes.

Warning signs include agencies that only showcase vanity metrics like page views, social shares, or generic "traffic increases" without connecting those numbers to revenue. Strong agencies use attribution models that track how content influences deals throughout the buyer journey and provide transparent reporting frameworks that tie their work directly to your business goals.

For an example of measurable outcomes, see this case study.

Flexible Engagement Models

Different growth stages require different partnership structures. Early-stage tech companies often benefit from project-based engagements that address specific content gaps, while scaling businesses need retainer models that provide consistent strategic support and content production. Evaluate whether an agency can scale with your needs as you grow.

Consider contract terms carefully: monthly commitments provide flexibility, while longer contracts should come with clear performance milestones. Clarify ownership of content assets and intellectual property upfront—you should own everything the agency creates for you. The right agency adapts their model to your situation rather than forcing you into rigid packages.

Industry Specific Knowledge

Vertical expertise transforms content quality. Agencies familiar with your industry's regulations, compliance requirements, and technical nuances create more accurate, credible content that resonates with sophisticated buyers. A SaaS content agency understands subscription metrics, product-led growth, and technical implementation challenges in ways that generalist agencies cannot replicate.

For deeper insight into how specialized partners operate, see this guide on working with a SaaS content agency.

Questions to uncover genuine expertise:

• What other companies in our industry have you worked with?
• How do you handle technical accuracy for complex product features?
• Can you discuss specific regulatory considerations for our vertical?
• What industry publications and thought leaders do you follow?

Surface-level understanding shows up quickly—agencies with real expertise ask informed questions about your specific challenges rather than offering generic solutions.

Communication And Alignment

Smooth collaboration depends on clear communication structures and cultural fit. Discuss how the agency handles day-to-day coordination: weekly check-ins work for most B2B teams, while monthly strategic reviews ensure broader alignment. Understand how they integrate with your marketing technology stack and whether they can work within your existing workflows.

The right agency should invest time learning your brand voice and messaging frameworks rather than imposing its own style. They should demonstrate how they'll maintain consistency across all content while adding their strategic perspective.

Red flags include agencies that are difficult to reach, consistently miss deadlines without communication, or seem resistant to feedback. Strong partnerships feel collaborative rather than transactional.

1. Ten Speed

Ten Speed is a leader in product-led organic growth for B2B SaaS companies. Our unique onboarding process helps us get deeply ingrained in your company’s unique positioning right from the start of our engagements. We focus on the content that will make an impact and deliver sustainable results long term.

Our agency was founded by marketers with years of experience in-house building the content machine at Sprout Social. With decades of in-house expertise working with top B2B SaaS companies, we have marketing solutions to handle your entire B2B SEO strategy — from keyword research to omnichannel content distribution.

Our B2B content marketing services include:

• Comprehensive audits
• Content marketing strategy
• Full-service SEO
• Product-led content marketing, including sales enablement
• Case studies, white papers, and thought leadership
• Distribution across marketing channels

Our results speak for themselves. In just 12 months, we helped Workvivo experience a 78% increase in organic traffic growth — a traffic value of over $54,000, which directly helped them get acquired by Zoom.

We also work with companies like Visible, which we helped go from a roller coaster of inconsistent traffic to a consistent growth machine, resulting in a 313% increase in traffic.

Ten Speed is a great fit for the growing B2B SaaS company that is ready for concrete SEO results and a comprehensive strategy that’s focused on demand generation, but doesn’t have a full in-house team. Most of our client engagements range from $10,000–$50,000 per month, but we also work in the $10,000 or less range.

2. Siege Media

Siege Media is another large agency that offers SEO services with a public relations slant. They’ve developed and nurtured strong relationships with media outlets that help them secure highly visible content placements.

They offer:

• SEO optimization and content strategy
• Localization
• Digital PR

Siege built Cin7’s SEO content from the ground up, starting with low-difficulty topics to build authority, and then targeting high-difficulty keywords. This strategy, combined with their technical website recommendations, resulted in a 40% increase in blog conversions.

If you’re a B2B company looking for an SEO agency that can also help you with public relations, Siege might be a good fit. Their end-to-end content strategy deliverables cost between $12,000 and $30,000.

3. Beam Content

Beam Content is a newer agency headed up by Brooklin Nash. He’s obsessed with one thing: experts. Beam’s content is more focused on bounce rate than SEO and traffic. It’s distributed content for smart, niche target audiences, based on intensive research from subject matter experts.

They offer:

• Expert-driven thought leadership
• Brand and executive social media management
• Go-to-market content
• B2B marketing strategy consulting

When Typeform turned to Beam for a more targeted content strategy, the exit rate on their content decreased by almost 25%. They also achieved a reduced bounce rate and increased time spent on page.

Beam is great for B2B companies that need help connecting with their audiences and getting them into the sales funnel, especially those that need to be a convincing authority in niche markets. They have a $5,000 per month minimum for client engagements, and most clients spend between $10,000 and $12,000 per month.

4. Brafton

As one of the larger agencies on this list, Brafton offers conventional content marketing services. Their distinguishing feature is their data-driven software, which they say helps drive impactful strategy decisions in marketing campaigns.

They offer:

• Email marketing
• Social media marketing
• SEO
• Paid ad development
• Inbound lead generation

Brafton’s SEO content services helped Webex’s new blog get off the ground and achieve rapid growth. Webex started with a mediocre domain authority and not much content. In a year, Brafton had helped them increase traffic by a stunning 640%.

Brafton is a great fit for companies that plan to scale to all possible content channels and want to get it all from one place. If you’re looking for a classic strategy from a predictable one-stop shop, Brafton is the way to go. Their pricing for content creation starts at $1 per word, and SEO consulting starts at $200 per hour.

5. ClearVoice

ClearVoice maintains a large network of freelance writers who have backgrounds in a broad variety of subjects. Whatever niche you’re thinking of, they can probably deliver on it.

They offer:

• Access to their freelancer network
• Support managing content production by the freelancers
• Fractional content production

ClearVoice helped 1205 Marketing scale up their B2B marketing business by providing freelancers who specialized in their clients’ fields. They were able to grow their marketing efforts tenfold through access to ClearVoice’s pool of freelancers.

For companies that have in-house strategy experts but need to expand their pool of writers, ClearVoice is a great partner. Their pricing varies based on the level of service you’re looking for.

6. Kalungi

Kalungi specializes in comprehensive go-to-market B2B marketing services for startups. They’re like a part-time marketing team for companies that don’t have one in house, and they offer a tried-and-true approach that works for a wide variety of companies and industries.

They offer:

• Fractional CMO and specialists
• CMO coaching
• Content marketing
• Branding and graphic design

You can look no further than PSignite to understand the kind of results Kalungi delivers. When the seasoned SaaS provider acquired CPGVision, they needed a digital presence overhaul on their new product. So they partnered with Kalungi, who delivered a 48% increase in organic sessions within six months.

Kalungi is a good fit for companies that need to outsource their go-to-market playbooks to an experienced team. Their full-service offering, which includes a fractional CMO, averages around $45,000 per month, but they offer a variety of service levels to suit different needs and budgets.

7. Omniscient Digital

Omniscient Digital is laser-focused on SEO content. As a smaller agency with a niche service offering, they only work with B2B companies and only on SEO-driven content.

They offer:

• Link building
• Content production
• SEO strategy
• Technical SEO

Their approach works especially well for startups and growing companies like Lokalise, that aren’t quite ready for a full internal team. Omniscient helped Lokalise get their organic strategy off the ground and increase their blog traffic by 280%.

Once Lokalise was ready to bring its strategy in house, Omniscient helped onboard the new content marketing lead and hand off responsibilities.

Omniscient is a great fit for companies that already have a sophisticated understanding of who they are and what their overall marketing strategy is, but need help producing SEO content. Their full-service engagements start at $10,000 per month.

8. Optimist

Optimist specializes in full-service marketing for growing B2B businesses. As a strategy-focused one-stop shop, they develop purposeful content that helps companies meet their short- and long-term marketing goals.

They offer:

• Content writing and design
• Strategy and operations
• Reporting and analytics

While they have a number of success stories, we can’t help but be impressed by their work with HelloSign. By prioritizing content that would bring in qualified leads, they helped the digital signature company scale traffic by 1,308%, leading to an acquisition by Dropbox.

They’re a great fit for businesses that want a full-service marketing partner who delivers quality over quantity.

9. Animalz

You may have heard of Animalz already — their brand-focused take on content marketing generates a lot of viral engagement. They prioritize authentic content that fully encompasses each brand’s unique voice and style.

They offer:

• SEO consulting
• Brand awareness and lead generation
• Product marketing
• Distribution

Brand management company Frontify can attest to the agency’s quality work. They came to Animalz because they had an established brand identity that they wanted to showcase in all their content. Animalz created content that was indistinguishable from Frontify’s voice and messaging — but increased organic search by 52%.

Animalz is a good fit for a company with an addictive brand image that wants to focus on making its content an extension of that. Their pricing varies depending on content needs, but simple articles start at around $2,500 each.

10. Thrive Internet Marketing Agency

Thrive is also on the bigger side, and that’s reflected in their huge suite of digital marketing services. One of their distinguishing features is a large department that’s focused solely on local SEO and reputation management.

They offer:

• Comprehensive SEO services
• PPC marketing
• Conversion rate optimization
• Web design and landing pages
• Marketplace marketing

Thrive helped Grow Strong Industries optimize their Amazon marketplace presence, reducing cost per click by 42% and increasing units sold by 33%.

If you’re looking for a comprehensive digital marketing agency that can improve your local SEO and visibility, then Thrive may be a good fit. They’re an especially great partner for the ecommerce space.

11. Velocity Partners

Like all the agencies on this list, Velocity delivers results, but they’re extra focused on true creativity. With copywriting, design, video, and web development skills under their belt, their content marketing services are delivered with extra spunk.

They offer:

• Strategy services
• Search engine optimization and PPC services
• Creative and brand services

To get an idea of their creative chops, just take a look at their work with InVision. Velocity delivered three super-fun top-of-funnel videos that showcased the creative, limitless spirit of the company’s whiteboard tool.

Velocity would be a good fit for any company that needs help building its brand identity and connecting with customers through high-quality multimedia content.

12. Content marketplaces

Of course, we can’t talk about the SEO world without acknowledging content marketplaces, which are much different from agencies. Instead of providing holistic services, content marketplaces allow you to order content a la carte on an as-needed basis.

Content marketplaces are sometimes derisively referred to as “content mills” because they are often accused of producing high volumes of low-quality content.

Frankly, that can be true.

However, reputable content marketplaces like The Hoth, Verblio, and Writer Access have endured for a long time for a reason. If you know how to work with them, they can help you achieve your marketing goals.

Content marketplaces may be a good fit for your company if you have a minimal budget, you’re in a less competitive industry, and you’re willing to put in the legwork on your end.

But to see success, you’ll need to have a strategy in place, be willing to create detailed briefs, and understand how to optimize content for search engines. In other words, these services work well when you just need a writer to execute the actual writing.

Five-hundred-word blog posts from places like The Hoth start at around $50 a pop, which is much more palatable for small businesses that are just starting out. But just keep in mind that, with content creation, you truly do get what you pay for.
