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 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: what the engagement actually covers, 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. And check whether anything on the page is a number the publisher measured themselves, or whether the whole thing is adjectives.
The selection premium, measured
B2B influencer marketing is a selection business dressed as a creative business. We measured 578 named authors posting under paid distribution and the spread between voices is larger than the spread between almost anything else we track.
| Measure | Result |
|---|---|
| Top decile of voices, engagement rate | 10.55% |
| Bottom decile of voices, engagement rate | 1.22% |
| Spread | 8.6 times |
| Engagement variance explained by which voice posted | 67% across accounts, 20% within one company |
| Does past performance predict future performance? | Yes: first half to second half, r = +0.82 |
| Does posting more raise the rate? | No: volume is flat |
| Effect of audience seniority on engagement | None: CXO to owner all 4.30% to 4.42% |
- An 8.6 times spread on engagement rate means the difference between your best and worst creator is worth more than any other decision in the programme. Not the brief, not the format, not the budget split.
- Performance is predictable at r = +0.82 from one half of the year to the next. That is unusually high and it has a direct commercial implication: a paid test across five creators for one quarter tells you, with real confidence, which two deserve an annual contract.
- Volume is flat. A creator posting twice as often does not produce a higher engagement rate. Buy the right voice more often only after you have established it is the right voice; do not buy frequency as a substitute for fit.
Source: Kiin Labs, LinkedIn Thought Leader Ads Benchmarks 2026 — 464 advertiser accounts, 2,563 campaigns, 10,541 creatives, 578 named authors, $10.46M of spend and 176 million impressions in the twelve months to 7 September 2026. Medians across advertiser accounts, never pooled totals. LinkedIn Audience Network excluded. Paired comparisons are within the same account in the same window.
What the brief cannot fix
The natural response to an 8.6 times spread is to try to close it with better direction. We tested that. Holding the author constant and comparing their own posts with and without each feature:
| Creative feature, same voice with vs without | Effect on engagement |
|---|---|
| First line under 60 characters | +5%, not significant |
| Second person, writing to “you” | 0%, not significant |
| Link in the post | -7%, not significant |
| Post length | no relationship at all |
| Questions, numbers, emoji | not significant |
| New creative vs an established post in the same account | index 91, wins only 42% of the time |
Every one of those features shows up in cross-account comparisons and disappears when you ask whether the same person does better with it than without. The cross-account pattern was telling you which kind of creator writes short hooks, not that short hooks cause engagement.
The last row is the one most programmes get wrong. New creative underperforms the incumbent post it replaces, scoring an index of 91 and beating it only 42% of the time. A creator programme that churns content monthly is throwing away its winners. Run the post that works until cumulative frequency kills it, which in our fatigue data is driven by how many times the audience has seen it, not by how many weeks it has been live.
The agencies
1. Kiin — best for creator programmes where the selection and the paid distribution are one decision
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. We are not a creator network and we do not hold a roster. What we hold is the measurement: 578 named authors, 10,541 creatives and $10.46 million of distributed spend, which is the only dataset we know of that answers how much the choice of voice is worth. The answer, 8.6 times between the top and bottom decile with r = +0.82 consistency, is why we run creator work as a selection problem. Practically: a paid test across four or five voices in quarter one, concentrate on the two that hold up, amplify only the posts clearing the 10% engagement threshold where the click curve turns, and keep the winners running until cumulative frequency, not the calendar, says to change them. Then feed engagement signals to outbound so sales works the accounts the creators warmed. Reporting is landing page clicks rather than LinkedIn’s default click field, influenced pipeline by account, and a self reported attribution field on the booking form. Tradeoff: if you want external creators sourced, contracted and managed at scale, we are the wrong shape and TopRank or Creator Authority below are built for it. We are strongest when the voices are your own people and the question is which of them to back.
2. TopRank Marketing — best for enterprise B2B influencer programmes with published research behind them
Full-service B2B marketing agency, 24+ years in business, 325+ clients and a stated network of 2,000+ influencers. Pricing not published. B2B influencer marketing is a named service line rather than an add-on, sitting alongside strategy, content marketing, search and answer engine optimisation, social and podcast marketing. Named clients are the top of the enterprise market: SAP, LinkedIn, Adobe, Dell Technologies, Salesforce, Smartsheet and Mitel. Published results include brand engagements up 167% for LinkedIn and, for Adobe, doubled engagement with a 150% lift in form completions. It also publishes its own primary research, a 2026 B2B Thought Leadership Report surveying 800 senior B2B marketers and a 2025 B2B Influencer Marketing Report, which is rare in this category and is the reason it gets cited as a source rather than just listed as a vendor. Tradeoff: built for enterprise scale and enterprise timelines. A Series A company wanting three creators live next month is not the brief this agency is shaped around.
3. Creator Authority — best for LinkedIn-specific creator campaigns with a certified partner status
B2B influencer marketing specialist and a certified LinkedIn Marketing Partner, which is the clearest credential on this page and not something the generalist social agencies hold. The stated offer is strategy, creator matching and measurement across a full funnel from awareness to acquisition, and the firm describes itself as founded by creator economy veterans with an expert advisory board. It runs two intake tracks, one for brands and one for creators joining its database, which tells you the model is a managed network rather than ad hoc sourcing. For a company that wants LinkedIn creators specifically, rather than a multi-platform influencer programme, the specialisation is real and narrow in a useful way. Tradeoff: it publishes almost nothing verifiable. No named clients, no case study numbers, no creator network size, no pricing, no stated headquarters. Ask for all five in the first call, because the partner badge is the only thing here you can check from outside.
4. Sculpt — best for organic and paid B2B social run together
Josh Krakauer's agency has done "100% B2B social" since 2012, company page content, community management, executive and employee programmes, B2B influencer campaigns and paid social, with video production in-house. Named clients: KnowBe4, Monotype, Remote, Loom, Blend, Netscout. If your LinkedIn problem is that nobody at the company posts and the company page is dead, this is the kind of agency that fixes that.
Tradeoff: breadth. Paid LinkedIn is one of five paid platforms and one of many services; expect social-team depth rather than Campaign Manager depth.
5. Giraffe Social Media — best for a UK B2B social programme across more than just LinkedIn
Portsmouth, UK, serving UK and global clients. Established 2012, so fourteen years in the category, and it states 500+ brands served. Pricing not published. The offer is social media management, content and creative, paid social and influencer marketing, and the service list explicitly names employee advocacy, thought leadership, community management and brand ambassadors alongside channel management. Platforms run beyond LinkedIn to Facebook, Instagram, Pinterest, TikTok, X and YouTube, which is the main thing that distinguishes it from the LinkedIn-only firms on this page. Named clients include OneFamily, Brother, Hemsley Fraser, SAP Taulia, L&C Mortgages, Sebamed, SE Controls, Noble Isle and the English Speaking Union, and the published result is 590,000+ organic video views on a Hemsley Fraser campaign. The positioning is turning your people and culture into content, which is the right instinct for a presence programme rather than an ads programme. Tradeoff: a genuinely multi-channel social agency, so if LinkedIn is 90% of your B2B market you are paying for breadth you will not use, and the published proof is reach rather than pipeline.
6. Understory — best for paid media, GTM engineering and LinkedIn content run by one team
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.
7. Windmill Growth — best for done-for-you founder LinkedIn brands with named revenue outcomes
The most case-studied founder ghostwriting shop on this page, with revenue rather than impressions as the headline number and the engagement work (commenting on the ICP's posts) done for you. "Without the AI accent" is the pitch, and the samples support it. The fit is a founder at a seed to Series B company who wants LinkedIn run end to end and measured in calls booked.
Tradeoff: organic-only; no paid amplification, so the audience is whoever the algorithm shows it to.
8. Agent3 — best for scaled 1:1, 1:few and 1:many programmes for global enterprise
The reference point for enterprise ABM done at scale: named-account programmes for Splunk, Salesforce and Adobe with the research, creative and RevTech to run them, and a consulting arm for companies that want to build the capability in-house. The fit is a global technology vendor with a named-account list in the hundreds and a sales organisation that will work the accounts marketing opens.
Tradeoff: enterprise minimums; a 20-account programme for a Series B company is not the shape of work Agent3 is built for.
9. Transmission — best for enterprise B2B go-to-market programmes across regions
Transmission is on this list for the company that needs paid media inside a multi-region enterprise programme rather than as a standalone channel. It publishes its own buyer research (a Gen X and Gen Z B2B buyer study, "The Yes Advantage" on behavioural biases) and is one of the few B2B agencies with Reddit partner status.
Tradeoff: enterprise scale and enterprise minimums; a $10k-a-month media budget is not what it is built for.
10. Walker Sands — integrated B2B across PR, content, demand and RevOps
Location not stated. Strategy covering research, GTM and brand; strategic communications covering PR, social and influencer relations; creative and content including original research and sales enablement; digital marketing covering paid media, SEO, GEO, automation and email; and revenue operations including CRM implementation and Clay integration. Serves technology, healthcare, manufacturing, professional services consulting, and supply chain and logistics, for growth stage and enterprise B2B. Pricing not published. Named clients include John Deere, KUKA, Paylocity, Semrush, Ensono, e2open, Hub Group, Aspentech and commercetools. Publishes its own B2B Growth Maturity Assessment and a B2B AI Search Visibility Benchmark, which is a genuine signal in a category where most agencies publish opinion. Tradeoff: breadth over channel depth. Paid media is one capability among five practices, no client results with numbers are published, and the enterprise client list sets the expected engagement size.
11. Refine Labs — best for demand programmes for Series B+ B2B tech, with published tiers
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.
12. DowSocial — best for UK thought leader ads with published fixed prices and a training option
The only agency on this list that publishes fixed prices for getting thought leader ads live, and the only one offering to teach your team instead of running it. Its own line, "in B2B they almost always outperform company ads, and most agencies still are not running them", matches the data. The fit is a company that wants the first campaign built properly and then run in-house.
Tradeoff: a small specialist; the managed retainer is on request, and the site does not publish client results.

Why creator programmes need paid distribution
An unamplified creator post reaches the audience that creator has already earned, and you are paying for access to it once. Put budget behind the same post and two things change.
- A person’s post beats a brand’s post at the same job. Paired within the same accounts and the same objective, personal posts deliver landing page clicks 22% cheaper with a 38% better click through rate, and on brand awareness 47% cheaper with more than double the click rate. That advantage only exists in distribution.
- The engagement threshold is high and non-linear. Between 2% and 7% engagement the click rate barely moves. Above 10% it reaches 0.880%, about 3.7 times a 0 to 2% post. Amplifying a mediocre creator post buys you the flat part of the curve.
- Video is 2.4 times more expensive per click than a static post in this format, $32.34 against $13.51, and while video is 14% of all such campaigns it makes up only 5% of the top quartile. Creator video is a brand instrument, not a traffic one.
The practical structure: pay the creator for the post, then pay LinkedIn to put it in front of the accounts you actually want, and choose which posts get amplified on measured engagement rather than on whose turn it is.
How to measure a B2B creator programme
- Landing page clicks, never clicks. The median total click through rate in this format is 4.56% and 91% of those clicks never reach your website. The landing page click through rate median is 0.46%. A creator report leading with 4.56% is reporting reactions and profile views as traffic.
- Use engagement rate to compare your own creators, never to benchmark against an agency’s case study. Within an account, the higher-engagement post gets a 50% better landing page click rate and wins 83% of the time. Across accounts the correlation collapses to +0.19. It is a within-programme comparison tool only.
- Measure the creator, not the campaign, and give it two quarters. Given r = +0.82 consistency, a quarter of paid testing across five voices is a genuinely decisive experiment. That is the single highest-return thing to spend the first three months on.
- Self reported attribution on the booking form. A creator programme generates a dozen indirect touches that end in a branded search. Last click will credit Google and you will cut the thing that worked.
What goes wrong
Buying reach instead of fit
Follower count is the easiest thing to buy and the weakest predictor available. An 8.6 times engagement spread across voices, with audience seniority showing no effect at all, says the question is whether this person’s audience is your buyer, not how many of them there are.
Over-briefing the creator
No craft feature we tested survives holding the author constant. Heavy direction converts a distinctive voice into brand copy and removes the only thing you were paying for. Brief the subject and the boundaries; leave the writing alone.
Refreshing content on a calendar
New creative scores an index of 91 against the incumbent post and wins only 42% of the time. Monthly refreshes destroy winners on schedule. Replace a post when cumulative frequency says the audience has seen it enough, not when the month ends.
Running it organic only
The measured personal-voice advantage, 22% to 47% cheaper clicks than a brand post, is an advantage in paid distribution. Unamplified, you buy one pass at an audience the creator already owns and no control over which companies see it.
Judging it on cost per lead in quarter one
This is a trust instrument. Measured on monthly cost per lead against a search campaign it will lose every month and get cancelled in month four, having been working.
How to choose
- Ask how they choose voices, and how many they test. The answer should involve testing four or five with real budget for a quarter, because performance is predictable at r = +0.82. An agency that names its three favourite creators on the first call is selling its roster, not your fit.
- Separate the four costs in the quote. Creator fees, agency management, content production, paid amplification. Two quotes that bundle these differently are not comparable and most of them do.
- Ask what they do with a post that works. New creative scores an index of 91 against the incumbent and wins only 42% of the time. The right answer is to keep running the winner until cumulative frequency kills it, not to refresh monthly.
- Ask how much they brief. No craft feature survives holding the author constant. Heavy direction turns a distinctive voice into brand copy. The good answer is subject and boundaries, not structure and hooks.
- Check they will amplify selectively. Only posts clearing roughly 10% engagement sit where the click curve turns. Amplifying everything on rotation buys the flat part of the curve.
- Agree the month-one measure in advance. Engagement rate and landing page clicks per voice. Not cost per lead, which will lose to your search campaign every month and get the programme cancelled in month four.
Frequently asked questions
What is B2B influencer marketing?
Paying people with credible professional audiences to talk about your product or category, usually on LinkedIn. It splits into two shapes that get confused: external creators and analysts with their own followings, and your own executives and practitioners as internal voices. The economics of choosing a voice are the same in both, and in our panel the gap between a top-decile and bottom-decile voice is 8.6 times on engagement rate, which makes selection the dominant variable in either model.
How much does a B2B influencer marketing agency cost?
Almost none of them publish a fee, including most on this page, so the honest answer is that you have to ask. Kiin publishes $2,500 to $9,500 a month with no media mark up. Programmes vary enormously because they bundle very different things: creator fees, agency management, content production and paid amplification may be all in one number or four separate ones. Ask which of those four your quote includes before comparing two quotes at all.
Does follower count matter when picking a B2B creator?
Much less than fit. The measured spread between voices is 8.6 times on engagement rate, and audience seniority has no measurable effect, with CXO, VP, director, owner and partner audiences all landing between 4.30% and 4.42%. What you are buying is whether that person’s audience contains your buyer and whether they hold attention, and neither is readable from a follower number. Test five voices with real budget for a quarter instead.
How do you know a creator will keep performing?
Because it is measurably predictable. Author performance correlates from the first half of the year to the second at r = +0.82, which is high enough to plan on. That is the commercial case for spending quarter one on a paid test across several voices: the result is not a snapshot, it is a reliable forecast of who is worth an annual commitment.
Should creator content be amplified with paid budget?
Yes, and it is where the advantage actually lives. Paired within the same accounts on the same objective, a personal post delivers landing page clicks 22% cheaper than a brand post with a 38% better click through rate, and 47% cheaper on brand awareness. Unamplified, you reach the audience the creator already earned, once, with no control over which companies see it. Amplify selectively: only posts clearing roughly 10% engagement sit on the part of the curve where click rate jumps, to 0.880% against about a quarter of that below 2%.
How much creative direction should we give a creator?
Brief the subject and the boundaries, then leave the writing alone. Holding the author constant, a short first line is worth +5% and is not significant, second person is 0%, a link is -7% and not significant, and length has no relationship. None of the craft features survive. Heavy direction converts a distinctive voice into brand copy and deletes the thing you paid for.
Does video work for B2B creator content?
For brand and attention, yes. For traffic it is expensive: creator video costs $32.34 per landing page click against $13.51 for a static post, roughly 2.4 times, and although video makes up 14% of these campaigns it accounts for only 5% of the top quartile. Use video where you want the person to be seen and understood, and static posts where you want people to leave the feed for your site.
How long should a B2B influencer programme run before we judge it?
Two quarters minimum, and judge different things at each stage. Quarter one is a selection experiment across four or five voices, measured on engagement rate and landing page clicks per voice. Quarter two concentrates budget on the winners and starts reading audience growth and influenced pipeline. Cost per lead in month two is the wrong test and the most common reason a working programme gets cancelled.
