How We Evaluated These Demand Generation Agencies

Every agency was checked against its own live website in October 2026. No agency paid for inclusion. Each one was scored on five criteria:

1. Demand gen is a named service. A dedicated demand generation page or offer, not a passing mention.

2. UK presence. A UK office or UK company registration.

3. Proof. Named clients or published case study numbers.

4. Who does the work. Strategy only, or strategy and execution.

5. Pricing transparency. A published starting price, or "Custom, not publicly disclosed".

Hey Sid is our own service. It ranks #2 behind Gripped, and its limitations are listed the same way as every other entry. Agencies already ranked in our best ABM agencies for B2B guide are left out here, so this list adds 7 agencies not covered there.

What Makes a Good B2B Demand Generation Agency in 2026

Demand generation is not lead generation with a new name. Lead generation captures buyers who are already looking. Demand generation builds familiarity with buyers before they look, so they recognise your brand when the time comes. For the full definition, see our B2B demand generation guide.

That matters because B2B purchases are made by a buying group of typically 6 to 10 stakeholders. An agency that reaches one of them leaves the other five to nine to form their own view.

The UK market splits into four types of demand generation companies:

• Full-funnel demand gen agencies. Paid media, SEO, content and web under one retainer. (Gripped, Blend, FINALLY)

• Warming and content specialists. Webinars, founder content, case studies and messaging that make outbound land warmer. (ORRJO, Remedy)

• Syndication and media networks. Content distributed through their own publisher sites, paid per lead. (Headley Media)

• Consultancies and managed services. Fractional teams or platform-powered services that run the programme with you. (Scaled, Hey Sid)

The first three types usually target by job title, industry or company. Very few run every channel against the same named people. That is the gap a person-level approach closes.

#1 Gripped: Best B2B Demand Generation Agency for UK SaaS

• Specialty: Demand generation, paid search and social, LinkedIn ads, SEO, GEO, ABM and website design for B2B SaaS and tech

• Pricing: Minimum ~$4,650 per month (£3,500); typical range ~$6,650 to $26,600+ per month (£5,000 to £20,000+). Ad spend billed separately.

• Best for: UK and European SaaS companies, Series A to mid-market, with a £10,000+ monthly marketing budget

Pricing may change. Always check the latest details on the vendor's website.

Gripped is a London demand generation agency founded in 2017 by two former SaaS executives. It works only with B2B SaaS and tech companies, and says 70% of its clients are in the UK and Europe.

Key results (reported by Gripped): Alight saw a 383% increase in pipeline deals and £188,000+ in revenue in 5 months. Data Interchange reported a 1,540% increase in qualified leads before its acquisition by Epicor.

Strengths: Published pricing, which is rare in this category. Rolling contracts with 3 months' notice. A 4.9/5 rating on Clutch from 29+ reviews, according to Gripped.

Limitations: SaaS and tech only, so industrial and services firms sit outside its focus. Targeting runs through standard platform audiences; person-level control across channels is not stated.

Best for: SaaS teams that want one agency to run paid, organic and web against pipeline targets.

#2 Hey Sid: Best for Demand Generation Aimed at Named Decision-Makers

• Specialty: Person-level advertising (Always On), LinkedIn outreach (Precision Connect) and done-for-you thought leadership (Authority Builder), run as one managed service

• Pricing: Custom, not publicly disclosed

• Best for: Sales-led B2B companies with long sales cycles, a defined account list and a marketing team of 1 to 4 people

Pricing may change. Always check the latest details on the vendor's website.

Hey Sid is a platform-powered managed service, not a traditional agency. It runs demand generation at the level of the individual: the specific decision-makers your sales team needs to reach, not a job title segment.

The difference shows up in a long sales cycle. A broad campaign reaches whoever matches the filters. Hey Sid serves your brand to the named people inside your target accounts, repeatedly, across LinkedIn, Meta and Google, so by the time sales calls, the buying group already knows who you are.

What sets it apart:

• Always On. Person-level ads with per-person control, refreshed with new done-for-you creative every 60 days. See Always On.

• Authority Builder. Thought leadership written for your executives, with top posts turned into ads.

• Precision Connect. LinkedIn outreach to the same people, sent after they have seen the ads and the content.

• The Influence Loop. All three run against the same individuals over 60 to 90 days, with engagement synced to HubSpot.

Results (Hey Sid case studies):

Strengths: One coordinated system instead of 3 separate vendors. GDPR-compliant by architecture. Works with spreadsheet account lists, not only a mature CRM.

Limitations: Not self-serve; programmes start after onboarding and a defined account list. LinkedIn is the outreach channel, with no cold email. Native CRM sync is HubSpot only.

Best for: Mid-sized B2B companies in industrial tech, infrastructure or niche SaaS where every account counts.

#3 Blend: Best for Brand, Website and Demand Gen Together

#4 ORRJO: Best for Warming the Market Before Outbound

• Specialty: Webinars, ABM warming, founder LinkedIn ghostwriting, content, podcasts, LinkedIn Ads and Google Ads

• Pricing: From ~$3,500 per month (€3,000); media spend paid directly to platforms

• Best for: B2B companies that have outgrown referrals and whose outbound lands cold

Pricing may change. Always check the latest details on the vendor's website.

ORRJO is a UK demand generation agency with offices in London and Glasgow. Its model runs demand gen ahead of outbound, so prospects recognise the brand before the first call. It also sells lead generation, with a discount when both run together.

Key results (reported by ORRJO): Aveni has 500+ meetings booked across a partnership in its fifth year. Pulsion's webinar series drew 280 registrations and 19 meetings in 4 weeks.

Strengths: Published starting price. Honest framing: ORRJO says demand gen is the wrong first spend if you need pipeline within 30 days.

#5 FINALLY: Best for Creative-Led Campaigns in Industrial B2B

• Specialty: Integrated demand generation campaigns, paid media, content, video, marketing automation and CRM

• Pricing: Retainers from ~$6,650 per month (£5,000), 6-month minimum; projects from ~$40,000 (£30,000)

Limitations: A 6-month retainer minimum. Built for campaign bursts and launches more than continuous account coverage.

#6 Headley Media: Best for Content Syndication at Scale

• Specialty: Content syndication, B2B lead generation, display advertising, ABM and intent data targeting

• Pricing: Custom, not publicly disclosed

• Best for: Technology vendors that need leads from a defined audience at volume

Pricing may change. Always check the latest details on the vendor's website.

Headley Media runs demand generation through its own network: 7 technology media brands and 300+ content syndication sites across 60 countries and 32 languages. It has worked in technology media since the late 1980s and is employee-owned.

Strengths: All leads are generated in-house, with no outsourcing to subcontractors, according to Headley Media. AI and human lead validation. Clients quoted on its site include Proofpoint.

Limitations: Lead-led, so it works closer to lead generation than brand building. Thought leadership and LinkedIn outreach for your executives are not part of the offer.

• Specialty: Content and thought leadership, channel activation, nurture and automation, pipeline reporting, GTM consulting

• Pricing: RevOps, sales and marketing from ~$1,330 per month (£1,000); consulting from ~$2,650 per month (£2,000); GTM projects from ~$4,000 (£3,000)

• Best for: Agencies and SaaS scale-ups that want senior, part-time support

Pricing may change. Always check the latest details on the vendor's website.

Scaled builds each engagement from four service blocks, weighted to where your pipeline is weakest. Its consultants say they have built and exited B2B businesses, and Scaled is best known for scaling agencies.

Strengths: The most transparent, time-based pricing on this list. Fixes positioning first when the gap sits upstream of demand.

Limitations: A fractional model, so execution capacity depends on the hours you buy. Named client results are not published on its demand gen page.

Best for: Founder-led agencies and SaaS firms that need strategy and hands-on execution, not a full team.

How Much Does a B2B Demand Generation Agency Cost in the UK?

Published UK ranges sit between about $4,000 and $33,000 per month. Polaris puts focused programmes at roughly £3,000 to £5,000 per month and integrated multi-channel programmes at £10,000 to £25,000 per month.

Media spend usually comes on top. Gripped reports typical client ad budgets of £5,000 to £35,000+ per month, billed separately from its fee. Ask every agency three questions:

1. Is media spend inside the fee or billed on top?

2. How many channels and accounts does the fee cover?

3. What will you report in month 3, and what in month 9?

Decision Framework

The Case for Person-Level Demand Generation

A typical demand gen campaign buys reach. A campaign targets a job title in an industry, and the platform shows it to whoever fits. That builds awareness, but not necessarily with the people on your account list.

Long sales cycles punish that gap. When a deal takes 12 months or more, and 6 to 10 people have a say, every stakeholder you miss is one who meets your competitor first.

Person-level demand generation flips the order. You start with the named people, then build reach around them. The same individuals see your ads, read your executives' posts and get a LinkedIn message from your team, in that sequence. Hey Sid's sequence is designed so that by the time outreach lands, the prospect already recognises the brand.

Running ads, content and outreach through 3 different vendors makes that coordination hard. Running them as one system makes it the default. If you are weighing the agency model against software, our guide to ABM agency vs ABM platform breaks down the trade-offs.

Gripped and Blend are the strongest picks for full-funnel programmes. ORRJO fits teams pairing demand gen with outbound. Hey Sid fits lean, sales-led teams that need to reach a defined list of decision-makers.

FAQ

How much does a B2B demand generation agency cost in the UK?

Published starting prices on this list run from £1,000 per month (Scaled) to £5,000 per month (FINALLY). Integrated programmes typically cost £10,000 to £25,000 per month, according to Polaris. Media spend is usually billed separately.

What is the difference between a demand generation agency and a lead generation agency?

A lead generation agency captures buyers who are already in market and hands you their details. A demand generation agency builds familiarity with buyers before they are in market. For long sales cycles, demand gen usually needs to run first.

Should I hire a demand generation agency or build an in-house team?

An in-house team needs paid media, content, design and reporting skills. Covering all of them is hard for a marketing team of 1 to 4 people. An agency or managed service fills the gaps without new hires.

Do I need a demand generation agency based in the UK?

Not necessarily. A UK office helps with workshops and UK market knowledge. Hey Sid serves UK and European companies from Sweden and is GDPR-compliant by architecture.

How long does B2B demand generation take to show results?

Expect engagement data within 60 to 90 days and pipeline impact within one sales cycle, typically 3 to 12 months for mid-market B2B. ORRJO advises against demand gen as a first spend if you need pipeline within 30 days.
