The best B2B agencies in 2026, ranked by specialty

The best B2B agencies do not compete for one crown. An agency that is excellent at paid search for software companies may be the wrong hire for a chemicals maker, and the reverse is just as true. Yet most lists of the best B2B agencies name a single winner, and that winner is usually the publisher. Choose on that basis and you can spend six figures a year before finding out you bought the wrong specialty.

So here is our disclosure, up front. Digica is our own agency, and we placed ourselves first, as the best B2B agency for B2B marketplaces specifically. We do not claim to be the best B2B agency overall. Every other agency here leads its own specialty, and if Digica's fit is not yours, one of them is probably the better call. The criteria are published below so you can check the call.

The buying side has changed as well. In its 2026 survey of nearly 18,000 business buyers, Forrester found that 94% use AI during their buying process, and that 13 internal stakeholders and nine external participants influence decisions on average (Forrester). An agency now has to reach a committee that researches through assistants as well as search. This guide is for marketing leaders and founders choosing a B2B agency, with figures checked on November 5, 2026.

How we ranked these B2B agencies

We ranked by specialty, not by size or a single overall score, using four criteria: who the agency serves, what it runs in-house, what it proves in public and how you engage with it.

Who it serves. A specialty only counts if the agency's own site and its named work support it. What it runs in-house. We read what each agency says its own team delivers. Public proof. We looked for a named case study with a stated result, and we ignored logo walls without any detail. Engagement model. We recorded any published prices, terms and minimums, and said so where there were none.

Every result quoted here is the agency's own claim, and we did not contact or audit any of them. We also checked that each agency is still trading under its name. Several lists still name agencies that have since merged into groups or been acquired. Agencies we looked at but left out were either doing the same job as a pick or showed too little recent public evidence.

Publishers rank themselves first on many lists for this search, and we are doing it too, so treat our number 1 with the same care as anyone's. The difference we can offer is the scope: first for B2B marketplaces only, with the reasons stated below and nine alternatives for everyone else.

The best B2B agencies side by side

Each agency below leads a different specialty, so read down the "Best for" column first. The engagement column shows only what each agency publishes on its own site, and "not published" means you need to ask.

A rank here means only the order in which we list specialties, apart from our own disclosed first place. Directive at number 2 is not "better" than Six & Flow at number 10. They do different jobs.

1. Digica: the best B2B agency for B2B marketplaces

Digica is the pick if you run a B2B marketplace or directory and need supply and demand to grow together. This is our own agency, so here is the case, and the limits, in plain terms.

We are an integrated team: search, content, outreach and the build, run by one group against one roadmap, instead of four suppliers who never speak to each other. The promise is simple. Leads and organic growth from the same engine. The people you meet are the people on your account. We work across B2B markets, and we do not work with B2C marketplaces.

What that looks like in practice:

• Being found first. We help businesses get listed first and mentioned more in search and AI answers, through SEO and GEO. Nobody can guarantee a position, and we do not.
• Leads from a proven, refined playbook. Our lead generation fills both sides of a B2B marketplace, buyers for your sellers and sellers for your buyers.
• SaaS as well. The same engine, pointed at a subscription product. One SaaS partner and referral program brought about 100 referred signups in two months, with 94% still active after onboarding.

The rest of the proof, kept anonymous by our rule on client names: 40,000+ listed agencies and 1M+ monthly users at a B2B agency marketplace, grown from five people. 275+ editorial placements in three months, leading to 60% revenue growth on a single business line, at a design B2B marketplace. And 10x+ organic impressions within six months at a water and wastewater marketplace.

Best for: B2B marketplaces, directories, B2B communities, agencies and SaaS products.

Pick this if you need both sides of a platform to grow together and you want one senior team instead of four suppliers.

Skip this if you need one channel run hard, or a specialist in one of the fields below. They will serve you better, and we will tell you so on a call.

Best B2B agencies for demand and pipeline

Four agencies lead here, and they split by what you need: paid media, a demand reset at scale, a whole outsourced team or enterprise account programs.

2. Directive: paid media

Directive calls itself the B2B PPC agency for SaaS, technology and industrial brands. Its scope runs from market analysis and campaign architecture through to bidding, landing pages and conversion tracking, and it also offers content, paid social and RevOps. It claims more than 130 strategists and more than 700 brands served. A published case study with Skillable reports 50% year-over-year pipeline growth. It says its fees are separate from media spend and are usually a flat retainer, a percentage of spend or a hybrid.

Pick this if paid search and social are your main growth lever and you can feed CRM data back into the campaigns.

Skip this if you are early stage with little search demand, or you need one senior generalist.

3. Refine Labs: SaaS demand generation at scale

Refine Labs says it has helped more than 300 mid-market and enterprise B2B tech companies with $50 million or more in annual recurring revenue move from lead generation to demand generation. Its entry point is a Revenue Performance Assessment, starting at $35,000 and taking six weeks, with no long-term commitment required. That diagnosis-first approach is unusual, and it is one of the few published prices on this list.

Pick this if you have $50 million or more in recurring revenue and want a diagnosis before you sign a retainer.

Skip this if you are below that scale, because a $35,000 assessment is a large first step.

4. Kalungi: outsourced team for smaller SaaS

Kalungi, based in Kirkland, Washington, serves B2B SaaS only, and shapes its offers around a company's revenue stage. It says it has worked with more than 280 SaaS companies, and that it took one client from no marketing to 330% growth in marketing-qualified leads and $4 million in pipeline in under six months. Its pay-as-you-go model is a monthly retainer you can cancel during any month, though its FAQ suggests 6 to 12 months as a good minimum to see an impact.

Pick this if you would otherwise be hiring your first CMO and a team at the same time.

Skip this if you are not SaaS, or you already have a strong team and need one channel.

5. Transmission: enterprise ABM

Transmission, headquartered in London with offices across the US, Asia Pacific and Europe, leads on account-based marketing, or ABM, for large global brands. It was named large agency of the year at the 2026 B2 Awards. Its published Software AG case reports a brief covering 511 key accounts, with $13.9 million in influenced pipeline and 118 influenced opportunities. It does not publish engagement terms.

Pick this if you have a defined list of hundreds of accounts and sales teams in several countries.

Skip this if your team or account list is small, since a program built for global brands will outrun it.

Best B2B agencies for content and search

Animalz and Foundation are close neighbors, and the difference is in the output. Animalz leads with writing and research, while Foundation leads with distribution and visibility.

6. Animalz: SaaS content

Animalz describes itself as a content marketing and SEO agency for leading B2B SaaS brands. It covers strategy, search and answer engine optimization, research-based reports and LinkedIn thought leadership, and it reports results such as 5x organic traffic in 12 months and 172% year-over-year growth in marketing-qualified leads. It says it embeds in your organization, and it publishes no prices.

Pick this if you have a clear market position and want content strong enough to carry it.

Skip this if you need channel execution such as paid media, or you are not SaaS.

7. Foundation: SEO and AI visibility

Foundation, based in Philadelphia, calls itself an AI visibility agency for B2B tech and SaaS, with SEO, digital PR, thought leadership and paid channels in its scope. Its Bitly case reports that citation share for link shorteners grew to 11.7% in a 12-month engagement, nearly double the next competitor. It also publishes its own research on 380,000 AI answers. Terms are not published.

Pick this if being cited in AI answers and on third-party sites is the goal.

Skip this if you need near-term pipeline from paid channels.

Best B2B marketing agencies for positioning and technical sectors

When the problem is what you stand for, or how to speak to a technical buyer, channel skills matter less than category knowledge. These two publish their prices, which makes them easy to budget for.

8. The Starr Conspiracy: positioning and brand

The Starr Conspiracy, founded in Fort Worth, Texas, in 1999, works only with B2B technology companies between $5 million and $500 million in recurring revenue, and says roughly 77% of its customers are in HR technology. Published work includes a 337% surge in PR share of voice for TalentLMS. Subscriptions start at $15,000 a month, and defined-scope projects start at $30,000. It also states that there is no handoff to junior account teams, which is worth asking any agency to put in writing.

Pick this if your problem is what you stand for, especially if you sell to HR buyers.

Skip this if you are outside technology, or you want a pure performance shop.

9. Altitude Marketing: life sciences and industrial

Altitude Marketing, based in Emmaus, Pennsylvania, serves life sciences, industrial and technology companies. It says every account team includes seven to nine specialists, with at least one from senior leadership, and that clients stay for three years on average, twice the industry norm by its own account. In one published case, a brand launch brought a client its first Tier 1 pharma prospect within two weeks. It publishes retainer tiers from $9,500 to $12,500 a month, $12,500 to $16,000 a month and $16,000 or more.

Pick this if your buyers are engineers or scientists, and generalists keep getting the language wrong.

Skip this if you are a SaaS company that wants a SaaS playbook.

The best B2B agency for RevOps

Six & Flow is the pick when your reporting breaks because your systems do not connect, and you need that fixed before you buy more marketing. Revenue operations, or RevOps, is the work of making sales, marketing and customer data agree.

Six & Flow, with offices including Manchester and London, is a HubSpot Elite Partner with more than 10 years of experience. It reports more than 1,000 successful projects and growth work for more than 500 brands. Its scope covers HubSpot implementation, RevOps consulting, demand generation, sales enablement, data and integrations. It publishes no prices.

Pick this if you cannot trace marketing to revenue because the systems do not connect.

Skip this if you do not use HubSpot, or if you need creative and media first.

What changed in B2B buying, and what to ask an agency

Buyers now do much more before they speak to anyone, so an agency has to influence a decision it cannot see. Ask how each agency works in that part of the journey.

The 6sense 2026 Buyer Experience Report, based on 4,607 buying journeys, finds that vendor contact comes on average 59.2% of the way through a 10.3-month cycle (6sense). So more than half of the cycle runs without you in the room, and an agency that only reports on form fills is measuring the last part of it. Our guide to the B2B buyer journey covers what this means for category and listing pages.

The practical result is five questions for every agency you shortlist. Who exactly will work on our account each week, and can you name them in the contract? Can you show a report that traces a campaign through to closed revenue? What is the notice period, and what happens to our accounts, content and data when we leave? Which channels do you run yourselves, and which do you subcontract? And what would make you tell us to stop?

The answers matter more than the case studies. A good agency will have ready answers to all five, and a few, like The Starr Conspiracy and Altitude, publish some of them. Our guide to what a growth consultant costs covers how the different fee models change what you can ask.

Three failure scenarios

These are the patterns behind most bad agency relationships. In Setup's 2025 survey of more than 400 brand and agency marketers, dissatisfaction with delivery rose to 48%, the top reason clients end a partnership. The scenarios and the dollar figures are illustrative.

1. The senior pitch and the junior delivery. A company signs after a strong pitch from two partners, then meets a new account manager a month later. Output is steady but the thinking has gone. Six months and about $60,000 pass before anyone says so. Naming the day-to-day team in the contract would have made that conversation possible in month one. This is a common complaint rather than a measured rate.
2. The channel specialist who cannot see pipeline. A paid agency reports falling cost per lead for a year while sales says the leads are poor. Nobody connected the CRM. In a 2026 survey of 631 marketing leaders by Anteriad and Ascend2, only 18% tracked marketing activity through to closed revenue with a complete attribution model. Asking for a pipeline report before signing would have exposed the gap.
3. The lock-in that outlives the strategy. A company signs a 12-month term, and then a new CEO changes the target market in month three. The contract runs on, and the agency keeps delivering work for a market that no longer matters. A 90-day exit clause would have cost little to negotiate at the start. Terms vary widely, so ask.

In each case, the agency was competent at something. The company bought the wrong thing, or failed to define what it was buying.

Choosing a B2B agency: a decision framework

Name the constraint first, then choose the specialty, then check the budget. Most companies only need one of these agencies at a time.

• If you run a B2B marketplace or directory, start with Digica, and compare us against the channel specialists below.
• If paid channels already produce pipeline and you want more of it, choose Directive.
• If you have $50 million or more in recurring revenue and demand has stalled, choose Refine Labs.
• If you are a SaaS company under about $10 million in recurring revenue with no marketing leader, choose Kalungi.
• If you sell to a named list of more than 100 enterprise accounts in several countries, choose Transmission.
• If you need writing that carries a point of view, choose Animalz. If you need visibility in search and AI answers, choose Foundation.
• If you cannot explain your position in one sentence, choose The Starr Conspiracy, especially in HR tech.
• If your buyers are engineers or scientists, choose Altitude Marketing.
• If you cannot connect marketing to revenue, fix that first with Six & Flow.

Our list of B2B marketplace growth consultants goes deeper for platform businesses, and our guide to agency directories helps if you want a longer list to research. For the wider strategy behind any of this, see our B2B marketplace growth strategy. Whichever you pick, set a review point at 90 days, and agree in advance what result would make you continue.

What the right agency is worth

The right agency is worth the months you do not waste, and the published prices make that cost easy to work out. Six months with the wrong specialty is often the largest marketing mistake a small team can make.

Take the prices above. At Altitude's published tiers of $9,500 to $16,000 a month, a year costs $114,000 to $192,000. At The Starr Conspiracy's $15,000 starting subscription, it costs $180,000. So six wasted months at those rates comes to $57,000 to $96,000, plus the opportunity you lost.

Budgets are also moving away from people. In the Content Marketing Institute's survey of more than 1,000 B2B marketers, 45% expected to increase investment in AI-powered marketing tools, while human resources ranked last at 9% (Content Marketing Institute). That makes it more important to know whose judgment you are paying for.

The number to take to your next budget meeting is what six months with the wrong specialty would cost you: half of the annual fee, plus the pipeline you would have built instead. The biggest cost of doing nothing is another year of buying activity without knowing what it produced.

FAQ

What are the best B2B agencies in 2026? It depends on the specialty. We list Digica for B2B marketplaces (our own agency, disclosed), Directive for paid media, Refine Labs for SaaS demand at scale, Kalungi for an outsourced SaaS team, Transmission for ABM, Animalz for content, Foundation for SEO, The Starr Conspiracy for positioning, Altitude for technical sectors and Six & Flow for RevOps.

What does a B2B marketing agency do? A B2B marketing agency helps companies that sell to other businesses generate demand and pipeline. Depending on its specialty, it runs paid media, content, SEO, account-based marketing, positioning or revenue operations, for a buying committee rather than a single consumer.

How much does a B2B agency cost? Few agencies publish prices. Among those that do, Altitude Marketing lists retainers from $9,500 to $16,000 or more a month, The Starr Conspiracy starts at $15,000 a month, and Refine Labs starts with a $35,000 assessment. Many others quote on request.

How do I choose a B2B agency? Name your main constraint first, such as pipeline, positioning or reporting, and pick the specialty that addresses it. Then ask who will work on your account, ask for a report traced to closed revenue, and check the notice period before you sign.

Are the top B2B agencies rankings independent? Many are not. Agencies often publish these lists and place themselves first, as we do for B2B marketplaces. Check the stated criteria, whether the publisher discloses its position, and whether the agencies' results appear on their own sites.

What is the difference between a B2B agency and a fractional CMO? A fractional CMO gives you one senior leader, part time, usually for strategy and direction. A B2B agency gives you a team that executes the work. Some, including Kalungi and Digica, combine senior leadership with a team that delivers it.
