01/ our service
B2B demand generation agency what we run for you
Six parts, built in order.
The content, audiences, ad accounts and data stay yours when the engagement ends.
01
Positioning and message
Which buyers, which problem, why you: sharp enough to fit in a LinkedIn post and a search ad.
Everything downstream spends less when this is right.
02
Founder-led LinkedIn content
A steady cadence of posts from the founder and team that your buyers actually read, planned around their problems, not your product release notes.
03
Paid LinkedIn and search
LinkedIn to your ICP and target-account lists for reach into the buying group; search for buyers already in market; retargeting to stay present.
Media spend is billed at cost.
04
Demand capture
The pages where created demand turns into meetings: pricing, demo, comparison and booking.
Fast routing to sales when a target account shows intent.
05
Measurement that reaches pipeline
Self-reported source on every booking, engagement from ICP accounts, pipeline by source, and a monthly decision on where the next pound goes.
06
Outbound and ABM where they help
Signal-led outbound to accounts showing interest, and account-based plays for the few that matter most, run from the same data.
Demand generation is one part of what we do.
For the full system see how we work as a GTM agency, and for outbound on its own, our B2B lead generation service.

03/ the first 90 days
How our demand generation engagements run the motion starts on day one
- 01
Start the motion
The first founder and team posts go out on LinkedIn, and conversations start with the target accounts you already know: warm introductions and existing contacts. We add the self-reported source field on day one.
DAY 1 - 02
Diagnose and sharpen the message
Where current pipeline comes from, where it stalls, and what buyers say brought them in. One core message and three or four angles, tested in the posts already running.
WEEKS 1 TO 2 - 03
Build the engine around it
One substantial asset, the pages that convert (pricing, demo, comparison) and the data and signals underneath, built while the content runs.
WEEKS 1 TO 4 - 04
Paid and capture join
LinkedIn to the ICP, search on the terms in-market buyers use, retargeting, and email to people who have opted in. Each is switched on as it is ready.
WEEKS 2 TO 4 - 05
Report on pipeline
ICP engagement, meetings, pipeline and self-reported source, reviewed with sales every fortnight.
FORTNIGHTLY - 06
Shift spend to what works
Cut what doesn't produce ICP conversations; put the budget where buyers say they found you.
MONTHLY
04/ the discipline
What is demand generation? and what it isn’t
LinkedIn describes demand generation as making it possible for buyers to learn about a product without direct sales contact, and lead generation as collecting contact details for sales to follow up.
Put simply, demand generation gets people interested; lead generation turns that interest into names.
Forrester's definition is more operational: a B2B demand programme has a defined audience and a set of inbound and outbound tactics aimed at a measurable objective: to activate, validate or accelerate demand.
Demand generation marketing is the whole of that: positioning, content, paid media, search, events and the measurement that ties them to pipeline.
One thing it is not: Google Ads' "Demand Gen" campaigns are a campaign type inside Google's ad platform.
They can be one channel in a B2B demand generation programme, but the name is the only thing they share.
What is B2B demand generation?
The same idea applied to committee purchases with long cycles: reaching the whole buying group, most of whom your sales team will never meet, so that when the account comes into market you are already on the shortlist.
Demand creation and demand capture
Demand creation reaches the buyers who are not in market yet, so you are known and trusted when they are.
Demand capture makes sure you are found and chosen by those who are: search, review sites, retargeting and a fast path to sales.
Refine Labs measures the two differently: software attribution for capture, self-reported attribution for creation.
05/ three motions
Demand generation vs lead generation and where ABM fits
→ Demand generation creates the interest that lead generation converts. See our lead generation service.
→ Demand generation for the market, ABM for the accounts that matter most. See our ABM agency UK page.
Most B2B teams need a blend.
The longer comparison is in demand generation vs lead generation.
06/ how buyers buy
Why demand generation matters more now buyers decide before they call
6sense's 2025 study of nearly 4,000 buyers found 94% of buying groups had ranked their preferred vendors before first contact, and the winning vendor was already on the day-one shortlist 95% of the time.
If you are not known before the buyer starts, you are rarely chosen after.
Buyers also prefer to do the work alone: Gartner found 61% of B2B buyers prefer a rep-free buying experience and 73% actively avoid suppliers who send irrelevant outreach.
And the group doing the buying keeps growing.
Forrester's 2026 study puts a typical purchase at 13 internal stakeholders and nine external influencers; its 2025 survey found 73% of purchases involve three or more departments, and in 2024 it found 86% of B2B purchases stall.
Demand generation is how you reach the people your sales team never meets.
07/ strategy
B2B demand generation strategy channels and the 95-5 rule
The Ehrenberg-Bass Institute's Professor John Dawes set out the arithmetic: if companies change a supplier about once every five years, only about 20% are in market in a year and about 5% in a quarter.
He is clear that 95% is a heuristic, not a precise rule.
With a two-year buying cycle, about 13% of buyers are in market each quarter.
So work out your own figure.
That shapes the strategy.
Most of the budget should reach the 95% who are not buying yet (content, LinkedIn, podcasts, events), and a smaller, sharper share should capture the few who are: search, retargeting, review sites and a fast route to sales.
LinkedIn found 96% of B2B marketers expected their ads' main effect within two weeks; a strategy judged on a two-week window will always over-spend on capture.
The channels that usually matter for B2B: LinkedIn (organic and paid), search, founder and team content, podcasts and newsletters, events and webinars, and, for named accounts, ABM.
We pick two or three to do well rather than seven to do badly.
08/ try it
How much of your market is buying now? the 95-5 rule, for your numbers
Set how often your customers replace what you sell, and how many accounts fit your ICP.
The arithmetic is Professor John Dawes's, from the Ehrenberg-Bass Institute.
The method: if customers replace a supplier every 5 years, about 1 in 5 is in market each year and 1 in 20 each quarter. Ehrenberg-Bass Institute ↗
In market this quarter
5%
About 50 of your 1,000 accounts are buying this quarter. 950 are not buying yet.
The small number is who you can capture this quarter.
The big number is who you need to reach now, so you are on the list when they come into market.
09/ the balance
Brand building and activation what the effectiveness research says
Read these as direction, not a formula.
A plan that spends everything on activation (forms, retargeting, SDR sequences) is optimised for the 5% and starves the 95%.
10/ paid social
LinkedIn ads for demand generation reach into the buying group
LinkedIn is where B2B buying groups can be reached by company, function and seniority, which makes it the backbone of most B2B demand generation.
Its company-list targeting matches your target accounts against more than 13 million LinkedIn Pages; lists need at least 300 companies, and LinkedIn recommends 1,000 or more.
We use LinkedIn ads in two ways: to put the founder's best content in front of the whole ICP (creation), and lead gen forms or retargeting for accounts already engaging (capture).
One published benchmark, from Metadata.io's customers, found a LinkedIn lead-gen form lead cost $193 against $346 via a landing page.
That is useful for capture, but a form fill is not a buyer.
11/ paid media
What B2B paid media costs one published benchmark
Metadata.io publishes benchmarks from its own customers: 153 B2B advertisers and $57.6M of 2025 spend.
The data is US-weighted and in US dollars, so use it for proportions more than absolute UK costs.
Cost per lead is a capture metric.
It says nothing about whether the lead's company was in your ICP or went on to buy.
12/ examples
Demand generation campaigns examples of what we run
Campaign types, not case studies: the kinds of programme we build, described plainly.
The founder point-of-view series
A weekly LinkedIn post from the founder on one problem your buyers have, amplified to the ICP with paid, and a monthly long-form piece that goes deeper.
The research report
Original data about your buyers' market (a survey or an analysis of public data), released ungated, then cut into posts, a webinar and sales conversations.
The event-anchored campaign
Six weeks around an industry event: pre-event content to the delegate companies, meetings booked on the day, and a recap report after.
The webinar series
A recurring session on a problem, not a product demo, promoted by email to people who have opted in and by LinkedIn to the ICP.
The comparison and pricing pages
Honest pages for buyers already comparing options.
They are often the highest-converting pages on a B2B site.
The target-account surround
For the accounts that matter most, LinkedIn company-list ads plus tailored content and sales outreach: demand generation meeting ABM.
13/ measurement
Measuring demand generation beyond MQLs
Forrester's waterfall benchmarks show that in a lead-centric process built on MQLs, less than 1% of inquiries become closed-won deals.
Forrester now tells clients to say goodbye to MQLs and measure buying groups and opportunities instead: its 2023 buyers' survey found 93% of buyers bought in a group of two or more, and 71% in a group of four or more.
Attribution software misses much of what creates demand.
In a 12-month test, Refine Labs found its software credited web search with 78% of conversions, while buyers named it only 12% of the time.
That is one agency's own data, but the method is worth copying: a mandatory, free-text "How did you hear about us?" field on the booking form, with no prompts.
We add it on day one.
14/ what we track
Demand generation metrics leading, then lagging
These are our working measures, not industry benchmarks.
For the strategy behind them, see our demand generation strategy guide.
15/ SaaS
Demand generation for B2B SaaS UK and US
SaaS buyers research alone, often trial first, and compare you with a dozen competitors.
So SaaS demand generation leans harder on content the buyer finds on their own (comparison pages, honest pricing, a founder whose posts they already read) and on capture that routes a trial from a target account straight to sales.
For UK SaaS companies selling into the US, the US market is larger and more crowded; we usually start with the ICP segment where you already have customers and proof, and expand from there.
16/ what it costs
What demand generation costs published prices in the market
Most agencies quote after a call.
These are the prices published by specialist firms listed further down, as a guide to the market.
What drives the price. The number of channels, how much content is produced, the paid media budget (almost always separate), and how much strategy and reporting sits on top.
Marketing budgets are tight: Gartner's CMO surveys put them flat at 7.7% of revenue in 2025 and 7.8% in 2026, with 15.3% of marketing budgets going to AI.
Demand generation has to show where it creates pipeline.
17/ UK rules

18/ before you sign
Seven questions for any demand gen agency including us
01
What do you report on?
Pipeline and revenue by source, or leads and cost per lead?
Ask to see a real monthly report.
02
How do you measure what software misses?
Self-reported attribution, ICP engagement, share of search.
Last-click alone under-invests in creation.
03
Who writes the content?
People who understand your buyer, or a content mill?
Ask for samples in a market like yours.
04
How is media billed?
Fees, media spend and platform costs as separate lines, with no hidden mark-up on spend.
05
Who does the work?
Named people in the proposal and the share of senior time.
06
What do you need from sales?
Demand generation fails when sales ignores what it creates.
Expect a regular pipeline review together.
07
How do we leave?
Notice period, and who owns the ad accounts, content, audiences and data afterwards.
You should.
19/ walk away
Red flags in a demand gen proposal what we would question
Guaranteed lead numbers
Leads are easy to buy.
A guarantee usually means gated content and bought lists.
Everything gated
Gating every asset optimises for form fills from the 5%, not trust from the 95%.
Reporting stops at MQLs
With under 1% of inquiries closing in MQL-led processes, the report needs to reach pipeline.
Media spend inside the fee
You cannot judge value if you cannot see what was spent on media.
No ICP work before launch
Spending before agreeing who you sell to is the most expensive shortcut there is.
Seven channels at once
Two or three done well beat seven done badly, especially on a flat budget.
20/ specialists

Demand generation FAQ
The questions B2B teams ask before hiring a demand generation agency.
Getting the right buyers interested in what you sell before they are ready to talk to sales, then turning that interest into pipeline.
LinkedIn describes it as letting buyers learn about a product without direct sales contact.
It runs the programme: positioning, content, paid media, search and capture, and the measurement that ties them to pipeline.
See what we run.
Demand generation creates interest; lead generation turns interest into names and meetings (LinkedIn).
See the comparison and our lead generation service.
Demand generation for committee purchases with long cycles: reaching the whole buying group, most of whom sales never meets, so you are on the shortlist when the account comes into market.
A founder's weekly LinkedIn point of view, an ungated research report, an event-anchored campaign, a webinar series, honest comparison and pricing pages, and ads to target-account lists.
See campaign examples.
Usually LinkedIn (organic and paid), search, founder and team content, and events or webinars, with ABM for the most valuable accounts.
Pick two or three to do well.
Engagement from ICP accounts, self-reported source on every booking, meetings, pipeline by source, and cost of pipeline.
Forrester found less than 1% of inquiries close in MQL-led processes.
See the metrics.
Being found and chosen by buyers already in market (search, review sites, retargeting and a fast booking path), as opposed to demand creation, which reaches buyers before they are looking.
Usually both: demand generation for the market, ABM for the accounts that matter most.
See our ABM agency page and ABM vs demand generation.
A plan for reaching the buyers not yet in market and capturing the few who are, with a budget split between the two and measures that reach pipeline.
No. Google's Demand Gen is an ad campaign type.
B2B demand generation is the whole programme; Google's campaigns can be one channel in it.
Of the firms we list, Gripped publishes from £3,500 a month with a typical £5K to £15K, and Refine Labs paid media from $14,000 a month.
Media spend is usually extra.
We scope and quote after a call.
See what it costs.
ICP engagement moves within weeks; meetings and pipeline usually within one or two quarters; revenue follows your sales cycle.
Most of your market is not buying in any given quarter (Ehrenberg-Bass).
Yes.
We are based in London and work with UK, European and US B2B teams, including UK companies expanding into the US.
