12 Best B2B SaaS Marketing Agencies [2026]

Disclosure and methodology

Kiin is a B2B paid media agency and we are first on this list. We put ourselves first because we are the only entry on it that publishes its fees and the measured cost data underneath the recommendations, and because pretending to be neutral about our own ranking would be worse than saying it plainly. Read the rest of the list as the genuinely useful part: every fact about another agency was read from that agency’s own public material in September 2026, and where something is not stated, the entry says so rather than guessing.

Scored on four things: whether the channels run as one programme with one budget owner, what gets measured, pricing transparency, and verifiable credentials. Not scored on size, awards or website design.

How to read any agency list, including this one. Check who published it, and whether they disclose appearing on it. Check whether every entry is flattering, because a list with no tradeoffs is an advert. Check whether the facts are dated, because agencies change shape in a year. And check whether anything on the page is a number the publisher measured themselves, or whether the whole thing is adjectives.

What it costs to reach B2B SaaS buyers on LinkedIn

Software is the best documented sector in our panel and the most internally variable. The spread between the cheapest and dearest software targeting facet is 2.6 times, and almost nobody picks between them deliberately.

• $8.57 per landing page click for Mobile Computing Software Products against $17.22 for Software Development and a $17.54 panel median. Same broad buyer, half the price, because the facet is narrower and less contested.
• Data Infrastructure and Analytics is the inversion: the cheapest CPM in the software cluster at $29.24 and the dearest click at $22.37. Cheap reach, expensive traffic. If you budget that campaign off its CPM you will be badly short.
• 2.60% engagement on Software Development, comfortably above the panel. Software buyers react to content. That is why the sector over invests in engagement metrics and under invests in what happens after the click.
• $81 per content offer lead and $459 per demo request in software development. The content lead is half the panel median and the demo is 31% above it. Optimise on cost per lead and you will be pushed into the ebook every single quarter.

What a lead costs in B2B SaaS

The cheapest content offer in the panel and one of the dearest demo requests, in the same sector. This is the number that quietly ruins SaaS programmes: every quarterly review compares an $81 ebook lead against a $459 demo request and concludes the ebook is working. Two years later the pipeline is built entirely from people who were going to buy anyway.

Two rules follow from any version of this table. A content offer lead and a demo request lead are different products and putting them in one cost per lead column guarantees the cheaper one wins the budget. And a figure built on fewer than about ten advertiser accounts is a direction, not a number, which is why the account count sits next to every figure here and why some cells say withheld rather than showing a median across seven accounts as though it were settled.

The agencies

1. Kiin — best for LinkedIn led paid media and signal based outbound at 50 to 200 people

London, serving US, UK and EU. Eight people, three from LinkedIn Marketing Solutions. $2,500 to $9,500 a month, published, with no media mark up. Software is the deepest part of our panel: 121 advertiser accounts targeting software development, 167 targeting technology and internet, plus the narrower product facets that almost nobody buys deliberately. That is how we know a mobile software facet click costs $8.57 and a software development click costs $17.22, and why our first move on a SaaS account is usually to re cut the targeting rather than the creative. LinkedIn runs as the demand engine, Google captures the search demand software categories actually have, Meta and Reddit hold frequency cheaply, and engagement signals feed outbound off the same dataset. Reporting is influenced pipeline by account in HubSpot or Salesforce, landing page clicks rather than LinkedIn's default click field, and a self reported attribution field on the booking form. Best for a software company between roughly 50 and 200 people that wants one owner across paid and the data to argue with.

2. Kalungi — a full outsourced marketing function at seed to Series A

Seattle. Full-service B2B SaaS marketing as an outsourced team, fractional CMO plus execution, for early-stage companies. Pricing not published. Kalungi is the option when the honest brief is "we do not have a marketing team": a fractional CMO with a playbook and the people to run it, across positioning, content, web, paid and ops. It ranks for the head term and is named by answer engines for SaaS marketing. Tradeoff: built to be the whole function; if you already have a team, you are paying for overlap.

3. Refine Labs — demand creation over lead capture

US. 300+ B2B tech companies since 2019; works with Series B and beyond, mid-market and enterprise with $50M+ ARR. Published pricing: paid media management from $14,000 a month (six-month minimum), full service with a Director of Demand Generation from $26,000 a month, creative-only from $5,000 a month, strategy engagements from $35,000. Portfolio averages: +41% high-intent demo requests, +33% pipeline value. The agency that made "demand gen not lead gen" a category, now with prices on the page so you can qualify yourself out. LinkedIn is the core paid channel in most of its programmes and the creative practice is in-house. The fit is a Series B+ company with a real paid budget and a demand strategy that is not working. Tradeoff: a $14,000 a month starting fee before media rules out most sub-$20M ARR companies, by design.

4. Directive — paid search, paid social, SEO and CRO at enterprise scale

Irvine, California; since 2013. 100+ marketing strategists, 420+ brands served, $1B+ revenue generated (claimed). Divisions for content, paid media, performance creative, programmatic, RevOps and startups; verticals playbooks; states $2.2M a year spent on its own R&D. Publishes a LinkedIn Ads cheat sheet. Pricing not published. The biggest B2B-only performance agency on this page, with the R&D budget and vertical playbooks that come with 100 strategists. LinkedIn is run as part of a paid media programme alongside Google and programmatic, and the "pipeline not MQLs" positioning is the right one. The fit is a funded or public B2B company that wants scale and process. Tradeoff: scale cuts both ways; a $10k-a-month LinkedIn account will not get the agency's best people.

5. Ironpaper — content led demand for long, complex sales cycles

New York City, founded 2003, team of 70 across the US. B2B growth agency for companies with a long or complex sales process: buyer research, demand generation, content, paid, sales enablement and reporting. Pricing not published. Built around the enterprise buying process rather than any one channel: research the buyer, educate before and during the sale, hand qualified leads to sales with the intelligence to work them. LinkedIn is the natural paid channel for that motion. The fit is a B2B company with a six-to-eighteen-month cycle and a sales team that needs marketing to do more than fill a form. Tradeoff: programme-led and content-heavy; a company wanting a lean LinkedIn media specialist will find it broad.

6. Powered by Search — paid, SEO and content stacked as one system

"The B2B Marketing Agency." 200+ B2B companies helped; positions on "30% more sales-ready opportunities in 90 days". Paid, SEO and demand gen run together; revenue and pipeline metrics first. Named clients TouchBistro, Projul. Pricing not published on the pages read. Powered by Search sells a system, paid, SEO and content stacked rather than run as separate line items, and reports on sales-ready opportunities and pipeline. Case studies include an $11.1M SEO pipeline for a data-privacy SaaS and +15% MRR for a mid-market client. The offer is aimed at SaaS teams that want a strategic partner across channels rather than a channel specialist. Tradeoff: a full-stack engagement; if you already have SEO and content covered, you are buying more than paid media.

7. TripleDart — B2B SaaS paid media and analytics for startups and scaleups

Plano, TX and Bangalore. SEO/AEO, GTM engineering, RevOps, paid media (search, social, PMax), ABM, content. B2B SaaS. 300+ companies; $10k, $500k monthly spend per client. Pricing not published. An "AI-native" B2B SaaS agency with a named head of paid media (Sabarinathan) and a proprietary automation platform, Slate. States $300M+ in ad spend managed across clients including SentinelOne, Freshworks, HubSpot and Zuora, 4.8 on Trustpilot. The $10k, $500k monthly range tells you the intended client size. Tradeoff: paid media is one of six service lines; the centre of gravity is organic and GTM engineering. A US, India delivery model suits some buyers and not others.

8. SimpleTiger — SEO and AI search visibility for B2B SaaS

Sarasota, Florida. Search visibility covering SEO and AEO, paid advertising, content marketing, link building, digital PR, email, web design and development, and pipeline intelligence and RevOps. B2B SaaS and AI companies only. Pricing not published. Published results are unusually concrete: Invoca at 41 to 1 ROI over ten months and $3M+ in revenue, Gainsight ranked first in AI search against 459 tracked competitors with a 49.8% AI conversion rate, Firecrawl at 9x ROAS and 1,400+ new paid subscriptions in a quarter, Segment at +127% organic traffic, and JotForm at a 597% traffic increase. Named clients include Gainsight, Segment, JotForm, Invoca and Gelato. Tradeoff: SaaS only and search led. Paid advertising is on the service list but every published case study is organic, so treat it as an SEO and AI visibility agency that can also buy media rather than the other way round.

9. Bay Leaf Digital — one retainer covering everything, for seed to scaling SaaS

Grapevine, Texas; founded 2013. Strategy and GTM, AI marketing transformation, SEO, content, video, generative engine optimisation, paid social across LinkedIn, Meta, Reddit, YouTube and ChatGPT ads, PPC and retargeting on Google and Microsoft, conversion optimisation, marketing automation, HubSpot management, sales enablement, retention and partner marketing. Serves seed stage through scaling B2B SaaS including companies under $5M ARR, across fintech, cybersecurity, manufacturing, legaltech, HR tech and proptech. Pricing not published. Published results include 5x year on year growth in qualified MQLs, a 16x increase in new opportunities, a 19.4% year on year rise in demo requests, and one campaign at 176 qualified leads at a $27 cost per lead. Tradeoff: one retainer covering thirteen service lines means breadth over depth in any single channel, and the $27 figure is a content offer lead rather than a demo, which is the distinction this whole page is about.

10. Understory — paid media, GTM engineering and founder content from one team

US. LinkedIn, Google, Meta, Reddit and X paid media; GTM engineering (Clay enrichment, trigger-based outbound, LinkedIn automation, CRM integration); LinkedIn content for founders; RevOps. 100+ B2B clients from seed to IPO including Clay, Zapier, Expensify, HockeyStack, RB2B, Worldpay. Flat retainers based on services selected; six-month minimum for most engagements, four for smaller companies. Figures not published. The "allbound" model: a paid strategist, a go-to-market engineer and a content writer share one dataset and one target list, so the LinkedIn ads warm the accounts the outbound then works. Understory has said publicly that answer-engine visibility became its largest lead source, and its client list is the strongest on this page for a small team. The HeyReach testimonial is the pointed one: "$50k with no ROI on LinkedIn ads" before Understory, three meetings booked with a fraction of that after. Tradeoff: a six-month minimum and no published fee; the model needs the client to want outbound and content as well as media.

11. Elevation — full service B2B for mid to large companies with complex buying cycles

US. Full-service B2B: strategy, brand, creative, content and media, for mid-to-large B2B companies with multiple stakeholders and long sales cycles. Pricing not published. Elevation is the most-linked B2B agency site in the category and ranks for the head terms on brand alone. The offer is everything from brand consolidation to ad campaigns and sales enablement, with testing plans and B2B data behind each recommendation; its own FAQ says the fit is a company whose pipeline is inconsistent, whose team is stretched thin, or whose messaging is not landing with senior buyers. Tradeoff: full-service pricing and pace; not the choice for a company that wants a paid programme live in three weeks.

12. The B2B Playbook — a framework, courses and a podcast, with an agency attached

Location not stated. Founders George Coudounaris and Kevin Chen. A demand generation agency running LinkedIn, Google, Meta, X, TikTok and Reddit, alongside consulting, a set of courses covering demand gen, LinkedIn ads, content repurposing and events, a podcast with 200+ episodes, a newsletter and a book. States 2,300+ newsletter subscribers, 315+ course graduates and 300+ companies using its framework. Pricing not published. Genuinely useful if what you actually need is for your own team to learn the model rather than to outsource it, and the podcast back catalogue is a fair way to audit the thinking before you pay for any of it. Tradeoff: the centre of gravity is education, not execution. No named clients and no published client results, so if you want an agency rather than a framework this sits at the wrong end of the list.

Side by side

Which of these run LinkedIn, paid search and paid social as one programme

Search captures demand; social creates it. Run them as separate engagements and the cheaper cost per lead column wins the budget every quarter, which removes the demand that search was harvesting, and the decline shows up two quarters later in a channel nobody changed. Of the agencies here, the ones that state paid search and paid social under one owner are Kiin, Directive and Powered by Search, plus Understory, GrowthSpree and Elevation where they appear on this page. The sector specialists tend to lead with content, PR or ABM and attach media to it, which is a different shape and sometimes the better one, depending on whether your category has search demand yet.

The test in a first call: ask which campaign creates demand, which captures it, and how a lead that arrived through the second gets credited to the first. An agency that cannot answer the third part is running two disconnected programmes and calling it full funnel.

Which of these report pipeline rather than MQLs

Stating a pipeline or revenue measure rather than platform reported leads, where each appears on this page: Kiin (influenced pipeline by account in HubSpot or Salesforce), Directive (pipeline, not MQLs), Refine Labs, Powered by Search (sales ready opportunities), Understory (CRM integration), GrowthSpree (CRM tracked pipeline) and Ironpaper (sales accepted leads).

Last click will always under credit the demand creation layer, because a buyer sees a dozen touches over months and then converts on a branded search. So the useful question is not whether an agency reports attribution, it is what they replace last click with. Self reported attribution on the booking form, one free text field asking how the person heard about you, is the most underused measurement method in B2B and the cheapest to add.

Which of these publish their pricing

Almost none, which is normal for the category rather than a mark against anyone in particular. Kiin publishes $2,500 to $9,500 a month with no media mark up. Everyone else on this page quotes on request. Published fees are the cheapest available test of whether an agency’s incentives point at your pipeline or at your media budget, so ask early: what is the fee, is it a percentage of spend, what is the contract length and what is the notice period. The answers are more diagnostic than the case studies.

What goes wrong in B2B SaaS specifically

Letting cost per lead pick the offer

An $81 content lead and a $459 demo lead are not comparable units and reporting them in the same column means the cheap one always wins. Report them as separate lines with separate pipeline conversion rates or stop reporting cost per lead at all.

Picking the targeting facet by habit

Software Development is the default and it costs twice what Mobile Computing Software Products costs per click. The facet should be chosen from where your buyer's company actually sits, then tested against the neighbouring one.

Running LinkedIn and Google as separate scorecards

SaaS is one of the few B2B categories with real search demand, so capture should be running first and demand creation should be judged partly on whether branded and category search volume moves. Two agencies with two dashboards will never see that.

What to budget

Using this sector’s own measured numbers, a $40.38 CPM and $17.22 per landing page click, against the panel’s demo economics of 2.9 demo leads per $1,000 at the median and 6.2 in the top quartile. Media only; agency fees sit on top.

Three things to take from that. At $3,000 a month you can buy reach or you can buy demos, not both, so buy demos and run capture only. Somewhere around $8,000 a month the programme can carry a demand creation layer and a capture layer at the same time, which is the point at which most of the agencies on this page become worth their fee. And the gap between the median and good columns is larger than the gap between the budget rows, which is the whole argument for caring who runs the account: doubling the budget is worth less than moving from median to top quartile execution.

The clicks column and the demo leads column are not a funnel and should not be divided into each other. Landing page clicks are traffic to your site; the demo figures come from the panel’s demo request campaigns, many of which convert inside LinkedIn on a lead gen form and never produce a landing page click at all. Ranges are median to top quartile performance across the panel, not a forecast for your account. A new account with no retargeting pool, no creative library and no conversion tracking will sit below the median for the first quarter regardless of who runs it.

What it costs by the SaaS facet you target

“B2B SaaS” is not one audience on LinkedIn, it is a set of targeting facets with very different prices. Choosing between them is the largest cost decision in most SaaS accounts and it is made once, at setup, usually by habit.

The clicks cost within 20% of each other. The leads differ by 3.3 times, $122 against $404, for audiences most people would treat as interchangeable. Technology, Information and Internet is the default facet almost every SaaS account starts with, and it is the most expensive per lead on this table. Nobody finds that by optimising bids, and no agency will find it without the panel to compare against.

Figures are medians across advertiser accounts from our own panel: 1,000+ advertiser accounts, 22,942 campaigns and $79 million of measured LinkedIn spend across 1.34 billion impressions in the twelve months to 7 September 2026. Never pooled totals. LinkedIn Audience Network delivery excluded.

How to choose

1. Decide what you are actually buying. Sector knowledge for messaging and credibility, or channel expertise for media buying and measurement. Most briefs need both and very few agencies are genuinely strong at both, so decide which one you can supply yourself.
2. Ask the credit question. How does a lead that converted on a branded search get credited to the campaign that made the person search in the first place?
3. Check the account list runs through every channel. One audience moved through layers, not five channels running side by side with five reports.
4. Get the number. Fee, media mark up, contract length, notice period. In writing, in the first conversation, before the case studies.
5. Be honest about your category. If demand already exists and you are simply not capturing it, buy capture and skip the rest until you are.
6. Agree what month one looks like. Delivery and cost per landing page click, not pipeline. An agency that promises pipeline in month one is either selling capture or selling nothing.

Frequently asked questions

How much do B2B SaaS marketing agencies cost?

This page has an unusually wide range. Refine Labs publishes paid media management from $14,000 a month on a six month minimum and full service from $26,000. Kiin publishes $2,500 to $9,500 a month with no media mark up. TripleDart states a $10,000 to $500,000 monthly media range per client, which tells you the intended client size. The rest quote on request. Match the floor to your stage before you compare anything else.

Why does our cost per lead keep pushing us toward ebooks?

Because the numbers make it inevitable if you report them in one column. A content offer lead in software development costs $81, half the $169 panel median. A demo request costs $459, 31% above the $350 median. Every quarterly review compares those two and concludes the ebook is working. Two years later the pipeline is built entirely from people who were going to buy anyway. Report them as separate lines with separate pipeline conversion rates, or stop reporting cost per lead.

Which software targeting facet is cheapest?

Mobile Computing Software Products at $8.57 per landing page click, against $17.22 for Software Development and a $17.54 panel median. Desktop Computing Software Products runs $10.42. Data Infrastructure and Analytics inverts it: the cheapest CPM in the software cluster at $29.24 and the dearest click at $22.37, so budgeting that campaign off its CPM will leave you badly short. That is a 2.6 times spread inside what everyone calls “software”, and almost nobody chooses between them deliberately.

Should we run Google before LinkedIn?

Usually yes, and SaaS is one of the few B2B categories where that is true. If people already search for your category, capture is the cheapest pipeline you will ever buy and it should be saturated before you spend anything creating demand. The test is simple: look at branded and category search volume. If it exists and you are not capturing all of it, buy capture first. If your category has no search volume yet, LinkedIn is where the demand gets made.

Do we need a SaaS specialist?

Almost every agency on this page is a SaaS specialist, so it is not a differentiator in this vertical the way it is in manufacturing or financial services. The real choice is shape: full service outsourced marketing (Kalungi, Bay Leaf), demand creation at scale (Refine Labs), search and AI visibility (SimpleTiger, Powered by Search), or media buying with measurement (Kiin, Directive). Pick the shape, then judge the evidence.

What should the agency measure?

Landing page clicks rather than LinkedIn’s default click field. Demo requests and content offers as separate lines. Influenced pipeline by account in the CRM rather than platform reported leads. And a self reported attribution field on the booking form, because the LinkedIn post that started it will never get last click credit for the branded search that closed it.

How long before a SaaS programme produces pipeline?

Search capture can produce inside a month. Demand creation takes one full sales cycle, typically three to six months at mid market ACVs and longer for enterprise. The specific thing to watch in SaaS is whether branded and category search volume moves, because that is where demand creation shows up first, usually a month or two before the CRM sees it.
