Quick Answer
Kiin is a London-based B2B LinkedIn Ads agency at 167-169 Great Portland Street, W1W. Eight people, three of them ex-LinkedIn Marketing Solutions, managing 200+ B2B ad accounts. London clients include Lead Forensics and Sova Assessment. We run full-funnel LinkedIn Ads plus signal-based outbound off one dataset, for sales-led B2B SaaS companies spending £3,000–£50,000 a month with £5,000+ ACV. Management fees are published: £2,500, £5,500 or £9,500 a month. What separates us from most London agencies is that LinkedIn is the core offer rather than one channel on a list, and every number we report is calculated on landing page clicks rather than LinkedIn's inflated total click figure.

Our London Clients

Two we can name.

Lead Forensics — B2B website visitor identification software, headquartered at 4 Old Park Lane in Mayfair with a further UK office in Portsmouth. We launched LinkedIn, Google and Meta together and are now extending into GTM outbound. Kirsty Dawe, their CMO:

💬 Kirsty Dawe, CMO, Lead Forensics
"Kiin has been an amazing partner for us. We launched LinkedIn, Google, and Meta together and are now exploring GTM outbound with them as well. They really know their stuff and are super proactive; it genuinely feels like they're part of the team."

Sova Assessment — talent assessment and skills-based hiring software, based at Eccleston Square in Pimlico. Nicola Fine on working with us:

💬 Nicola Fine, Sova Assessment
"They take the time to really understand our business, audience, and our product. It's clear they care about our success as much as we do."

Both are London B2B SaaS companies selling into complex, multi-stakeholder buying processes — HR tech and sales intelligence respectively. That is the shape of company this works best for.

The London B2B Market

London is the densest B2B SaaS market in Europe and that changes how LinkedIn behaves in three specific ways.

Your competitors are bidding on the same people. A London-focused audience of, say, marketing directors at 200–1,000 employee SaaS companies is small — often 10,000 to 25,000 people — and heavily contested. CPMs run higher than a national UK campaign because you are in an auction with every other London B2B advertiser targeting the same narrow group.

Frequency arrives fast, so saturation is the real constraint. On an audience that size, a £5,000 monthly budget will hit high frequency within weeks. The failure mode is not underspending, it is showing the same three creatives to the same 15,000 people forty times. Penetration and frequency need watching weekly in London, and creative rotation matters more than it does on a broad national campaign.

Location targeting is messier than it looks. LinkedIn location is based on profile data, and plenty of people working in London still have a profile location from wherever they last lived. Targeting "London" alone systematically under-reaches. Better to target Greater London plus the commuter belt, or drop geography entirely and target by company when you have an account list — which is what we usually do.

⚠️ The London mistake we see most
Companies with genuinely national or European ICPs restricting targeting to London because they are based here. Your buyers are not in London because you are. Unless you sell something requiring physical proximity, geography is usually the wrong first filter — job title, seniority and company profile matter far more, and geographic restriction on an already-small B2B audience is how you end up with a 12,000-person audience and a frequency of 30.

Specialist vs Generalist in London

London has no shortage of digital agencies that will run LinkedIn Ads. Found, ClickSlice, Get-Found, Flow20, Reflect Digital and Passion Digital all offer it competently as part of a broader paid media practice, and for some companies that consolidation is genuinely the right answer.

The tradeoff is depth. LinkedIn rewards platform-specific knowledge more than Meta or Google do, because so much of what determines performance is invisible in the interface: which Campaign Manager defaults are optimised for LinkedIn's revenue rather than yours, why account history follows you, which metrics mean what they appear to mean.

Kiin has three ex-LinkedIn Marketing Solutions employees on a team of eight. That is the argument for a specialist, and it is also the honest reason to pick a generalist instead: if LinkedIn is one of five channels you need run and no single one is your primary engine, a full-service London agency will serve you better than we will.

How We Work With London Companies

Remote-first, with in-person when it is useful. We are at 167-169 Great Portland Street, W1W, which is central enough that quarterly planning sessions in person are easy for most London clients. Day-to-day is bi-weekly calls and a written monthly report.

The work itself is the same as described on the UK page: eight-layer audit, account list, full funnel build, then engagement signals feeding outbound from around week six.

The London-specific difference is pacing. On smaller, contested London audiences we usually run more creative in rotation and refresh it faster, and we watch frequency weekly rather than monthly. That is a real operational difference, not a positioning one.

Frequently Asked Questions

Where is Kiin based in London?+
Kiin is at 5th Floor, 167-169 Great Portland Street, London W1W 5PF. The team is eight people working remote-first across the UK, EU and US, with London as the base. Day-to-day work is bi-weekly calls and written monthly reporting, with in-person planning sessions where they are useful.
Do you work with London B2B SaaS companies?+
Yes, that is the core of what we do. Named London clients include Lead Forensics, the B2B website visitor identification platform headquartered in Mayfair, and Sova Assessment, the talent assessment software company based in Pimlico. Both are B2B SaaS companies selling into complex multi-stakeholder buying processes, which is where a full-funnel LinkedIn approach works best.
Are LinkedIn Ads more expensive in London?+
CPMs generally run higher for London-focused B2B audiences because those audiences are small and heavily contested by other London advertisers targeting the same people. The bigger practical issue is not cost but saturation: a London audience of 10,000 to 25,000 people reaches high frequency quickly, so creative rotation and weekly frequency monitoring matter more than they would on a national campaign.
Should I target only London on LinkedIn?+
Usually not, unless you sell something that requires physical proximity. LinkedIn location comes from profile data, so many people working in London still show an older location, meaning London-only targeting systematically under-reaches. More importantly, most B2B companies have national or European buyers and restrict targeting to London simply because that is where they are based, which shrinks an already small audience and drives frequency up. Job title, seniority and company profile are usually better filters.
How much does a London LinkedIn Ads agency cost?+
London agencies typically charge £2,000 to £10,000 a month in management fees, or 10 to 20 percent of ad spend, with most quoting only on a call. Kiin publishes its fees: £2,500 a month for LinkedIn Ads, £5,500 for full paid media, £9,500 for paid media plus GTM outbound. Ad spend sits on top, and around £3,000 a month in media is the practical floor for a genuine full-funnel test.
Should I use a specialist or a full-service London agency?+
If LinkedIn is your primary demand channel, a specialist will go deeper, because much of what determines LinkedIn performance is platform-specific knowledge that is invisible in the interface. If LinkedIn is one of five channels and none dominates, a full-service London agency such as Found, Passion Digital or Reflect Digital will serve you better than a specialist would, and the consolidation is worth more than the extra depth.
