The shortlist by need

• LinkedIn-led paid media joined to outbound and content: Kiin, Understory
• An outsourced or full-service SaaS marketing team: Bay Leaf Digital, Elevation, Kalungi

Almost every agency on this page works mainly or only with SaaS, so sector knowledge is not the differentiator it is in manufacturing or financial services. What differs is shape: an outsourced marketing team that does everything, a paid media specialist joined to outbound, a search and content agency that can also buy media, a large demand agency built for funded companies, or an education business with an agency attached. Pick the shape first, then judge the evidence.

The agencies, by what they are best for

Best for LinkedIn-led paid media joined to outbound and content

Sales-led SaaS that wants one owner across paid channels, with ads, outbound and content working off the same account list.

1. Kiin

Best for LinkedIn-led paid media and signal-based outbound for sales-led B2B SaaS

London (Great Portland Street, W1W). Founded 2019; team of 8, three of them ex-LinkedIn Marketing Solutions. LinkedIn, Google, Meta and Reddit run as one funnel for sales-led B2B SaaS, reported as pipeline. Benchmarks every account against the Kiin Labs panel: $65M+ of LinkedIn spend across 1,000+ advertiser accounts. Published fees: LinkedIn Ads $2,500 a month, LinkedIn + Google $4,500, full paid media $5,500, GTM outbound from $4,000. No mark-up on media; recommended ad spend about $5,000 a month.

LinkedIn runs as the demand engine, Google captures the search demand software categories already 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.

Named results: Storysnap, $3M+ influenced pipeline and $1.28M closed won; Lumi AI, blended CPL from $455 to $176. All results: case studies. Service page: how Kiin runs SaaS marketing.

Tradeoff: we are paid media led. If you need SEO, content production, brand or a website from the same team, pick an agency in another group.

5. Understory

Best for 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 and Worldpay. Flat retainers by service; figures not published.

The "allbound" model puts a paid strategist, a GTM engineer and a content writer on one dataset and one target list, so the LinkedIn ads warm the accounts the outbound then works.

Tradeoff: six-month minimum for most engagements (four for smaller companies) and no published fee; it suits clients who want outbound and content as well as media.

Best for an outsourced or full-service SaaS marketing team

SaaS companies without a marketing team, or with a stretched one, that want positioning, content, web and media from one partner.

2. Bay Leaf Digital

Best for 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, CRO, marketing automation, HubSpot management, sales enablement, retention and partner marketing. Seed stage through scaling B2B SaaS including companies under $5M ARR. Pricing not published.

Serves fintech, cybersecurity, manufacturing, legaltech, HR tech and proptech SaaS. 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.

3. Elevation

Best for 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.

The offer runs 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.

4. Kalungi

Best for 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 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.

Tradeoff: built to be the whole function; if you already have a team, you are paying for overlap.

Best for SEO, AI search and content-led demand

SaaS companies where organic search, AI answers and content are the main growth lever, with paid alongside.

6. Ironpaper

Best for 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 one channel: research the buyer, educate before and during the sale, and hand sales qualified leads with the intelligence to work them. The fit is a company with a six to eighteen month cycle.

Tradeoff: programme-led and content-heavy; a company wanting a lean paid media specialist will find it broad.

7. Powered by Search

Best for paid, SEO and content stacked as one system

Location not published on the entry. 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.

Powered by Search sells paid, SEO and content as one system rather than separate line items, reported 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.

Tradeoff: a full-stack engagement; if SEO and content are already covered, you are buying more than paid media.

8. SimpleTiger

Best for SEO and AI search visibility for B2B SaaS

Sarasota, Florida. SEO and AEO, paid advertising, content marketing, link building, digital PR, email, web design and development, pipeline intelligence and RevOps. B2B SaaS and AI companies only. Named clients include Gainsight, Segment, JotForm, Invoca and Gelato. Pricing not published.

Published results are concrete: Invoca at 41 to 1 ROI over ten months and $3M+ in revenue, Firecrawl at 9x ROAS and 1,400+ new paid subscriptions in a quarter, Segment +127% organic traffic, and JotForm a 597% traffic increase.

Tradeoff: SaaS only and search-led. Paid advertising is on the service list but the published case studies are mostly organic, so treat it as an SEO and AI visibility agency that can also buy media.

9. TripleDart

Best for AI-native SaaS growth with paid media and analytics inside it

Plano, TX and Bangalore. SEO/AEO, GTM engineering, RevOps, paid media (search, social, PMax), ABM, content. B2B SaaS. 300+ companies; $10k to $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.

Tradeoff: paid media is one of six service lines; the centre of gravity is organic and GTM engineering, and a US and India delivery model suits some buyers and not others.

Best for demand creation and performance at scale for funded SaaS

Series B+ and public software companies with a real paid budget that want scale, process and a demand strategy.

10. Directive

Best for paid search, paid social, SEO and CRO at enterprise scale

Irvine, California; since 2013. 100+ marketing strategists; 420+ brands served. Divisions for content, paid media, performance creative, programmatic, RevOps and startups; vertical playbooks; states $2.2M a year spent on its own R&D. Pricing not published.

A B2B-only performance agency with vertical playbooks and a "pipeline not MQLs" position. Paid search and LinkedIn are run as part of a paid media programme alongside programmatic and creative. The fit is a funded or public B2B company that wants scale and process.

Tradeoff: scale cuts both ways; a $10k-a-month account will not get the agency's most senior people.

11. Refine Labs

Best for demand creation over lead capture for Series B+ SaaS

US. 300+ B2B tech companies since 2019; works with Series B and beyond, mid-market and enterprise. Published pricing: paid media management from $14,000 a month (six-month minimum), full service with a Director of Demand Generation from $26,000, creative-only from $5,000, strategy engagements from $35,000.

Prices are on the page, so you can qualify yourself in or out. LinkedIn is the core paid channel in most of its programmes, creative is in-house, and it publishes portfolio averages of +41% high-intent demo requests and +33% pipeline value.

Tradeoff: a $14,000 a month starting fee before media rules out most smaller companies, by design.

Best for learning the demand gen model in-house

Teams that want to learn a framework and run it themselves rather than outsource it.

12. The B2B Playbook

Best for a framework, courses and a podcast, with an agency attached

Location not published. Founders George Coudounaris and Kevin Chen. A demand generation agency running LinkedIn, Google, Meta, X, TikTok and Reddit, alongside consulting, courses on 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.

Useful if what you 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, with no named clients or published client results; if you want an agency rather than a framework, look at another group.

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.

Source: Kiin Intelligence, 1,000+ advertiser accounts, 22,942 campaigns and $65M+ of spend across 1.34 billion impressions in the twelve months to 7 September 2026. Medians across advertiser accounts, never pooled totals, LinkedIn Audience Network excluded. The industry is the campaign’s targeting facet, not the advertiser’s own industry. Full tables and method: LinkedIn Ads Benchmarks 2026.

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.

Cost per lead figures from Kiin Labs Report No. 3 (lead gen forms, 489 advertisers). 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.

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.

Paid media can create demand, but outbound is often needed to turn that interest into conversations. Tools like Instantly help SaaS teams find prospects and run cold email campaigns alongside their paid activity.

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 $5,500 a month with no media mark up. Of the rest, Refine Labs and TripleDart also publish a price (see the list under the comparison table); everyone else 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 $65M+ 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, or channel expertise for media buying and measurement. Few agencies are strong at both, so decide which 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 and notice period, in writing, in the first conversation.
5. 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.
