The best B2B SaaS marketing agency for you depends on two things: how you plan to grow, paid media, full demand generation, organic and AI search, or outbound sales, and your stage, because the agencies built for £10m+ ARR companies are rarely the right fit at seed. Below are six UK agencies that work with B2B SaaS, what each is genuinely best for, what they publish about cost, and how to choose between them.
Full disclosure: this list is written by Brightpace, and we’ve put ourselves first. We’d rather say that plainly than pretend to be neutral. Everything we say about the other agencies comes from their own public websites as of October 2026, and each is strong at something, so use the “best for” labels to find your fit, even if it isn’t us.
How we chose
Every agency on this list:
- Works with B2B SaaS or software companies: either exclusively or as a stated specialism
- Has a UK base: London or Manchester, or (for Brightpace) works with UK companies remotely
- Is clear about what it does: a defined service, not “full-service everything”
We’ve grouped them by growth engine, because the biggest mistake SaaS companies make is hiring an excellent agency for the wrong job.

The best B2B SaaS marketing agencies in the UK
1. Brightpace
Best for: SaaS companies that want senior paid media run to CAC and payback, including those too early for a £10k-a-month agency.
Yes, this is us. Brightpace is a founder-led paid media specialist: you work directly with the person running your paid search, LinkedIn and paid social, with campaigns optimised to demos, trials, pipeline and revenue from your CRM rather than MQLs. See how we work as a SaaS PPC and paid media agency, and with startups and B2B businesses.
- Clear pricing. A monthly fee agreed up front, scaled to your ad spend and scope, with no setup fee.
- 30-day rolling contracts. No notice period beyond a month.
- Measured on business numbers. CAC, payback and pipeline, with offline conversions fed back to the platforms: see our sample weekly report.
Worth knowing: we only do paid media. If you need SEO, content, a new website or a full demand-generation team, one of the agencies below will suit you better.
2. Gripped
Best for: Series A to growth-stage SaaS that wants one agency across strategy, paid, ABM, SEO and the website.
London-based Gripped, founded in 2017, works with B2B SaaS, AI and tech companies at £2m to £50m ARR, and says it doesn’t work with pre-product-market-fit companies. Its services span go-to-market strategy, demand generation, ABM, paid search and social, SEO, GEO and SaaS website design. It’s one of the few specialists to publish pricing: retainers typically start at £5k a month, most clients invest £8k–£12k a month in fees, and it recommends at least £5k–£10k a month in media, on rolling contracts with three months’ notice.
3. Team4
Best for: SaaS companies building an inbound engine from seed to scale-up.
Team4 is a small London specialist, founded in 2023, focused on inbound marketing for SaaS and technology companies: SEO, content, AI search visibility, Webflow development and paid media, delivered through its own “Inbound Engines” framework. It says it works with B2B SaaS teams from seed to £20m+ ARR, typically investing £3k or more a month in marketing.
4. Kurve
Best for: scale-up and enterprise tech brands that want a paid media and growth partner.
Founded in 2016, London-based Kurve is a performance marketing and growth agency for B2B and consumer tech, covering paid social, paid search, programmatic display and app marketing, with a strong emphasis on experimentation and attribution. A good fit when you’re spending at scale across several channels and want a team embedded with yours.
5. Passion Digital
Best for: SaaS and fintech companies that want search-led growth, organic and paid together.
Passion Digital is an independent, search-led performance marketing agency in London, founded in 2012. It combines organic marketing, SEO, GEO, content and digital PR, with paid media including PPC, paid social and programmatic, and highlights SaaS, fintech and B2B services among its specialisms.
6. Flowd
Best for: SaaS and B2B companies that want qualified sales meetings from outbound, not ads.
Manchester-based Flowd is a B2B lead generation agency running fully managed cold email and SDR calling to book sales meetings, with a 30-day break clause and a stated 14 days to launch. It isn’t a paid media or SEO agency, but if your best channel is reaching named accounts directly, it solves a different problem from everyone else on this list.
Also worth knowing: specialists outside the UK
Two non-UK agencies come up often in searches for SaaS marketing help:
- Kalungi (US): a full-service B2B SaaS marketing agency known for its T2D3 playbook and CMO-as-a-service model, with engagement models tiered by ARR.
- Scalerrs: an organic search specialist for SaaS, covering Google SEO, AI search, YouTube, Reddit and third-party listicles.
What B2B SaaS marketing agencies cost
Few specialists publish prices, but those that do give a useful range:
- Full demand-generation agencies: Gripped publishes typical fees of £8k–£12k a month, plus at least £5k–£10k a month in media.
- Inbound specialists: Team4 says its clients typically invest £3k or more a month in marketing.
- Paid media specialists: usually a percentage of ad spend (commonly 10–20%) with a monthly minimum, or a fixed monthly fee agreed up front.
The fee matters less than whether the agency can hit a customer acquisition cost your business can afford. Work out your numbers first with our LTV:CAC calculator, and see our guide to what PPC management costs in the UK.
How to choose a B2B SaaS marketing agency
- Match the agency to your growth engine. Paid media, full demand generation, organic search and outbound are different skills. Decide which one you need most right now.
- Check they work at your stage. Many specialists set a minimum ARR or budget. Ask what size of company they do their best work for.
- Ask what they optimise to. For SaaS, that should be pipeline, customers, CAC and payback, not MQLs, clicks or platform-reported conversions.
- Check they can use your CRM data. Feeding opportunities and closed deals back to Google and LinkedIn is what stops campaigns optimising for cheap, unqualified sign-ups.
- Read the notice period. Rolling contracts range from one month to three. Know how quickly you can leave if it isn’t working.
- Meet the people doing the work. Ask who runs your account day to day, and how senior they are.
- Ask to see a sample report. It shows what they think matters. Here’s ours, and here’s what a SaaS PPC report should include.

FAQs
What does a B2B SaaS marketing agency do?
It plans and runs the marketing that brings in new customers for a software company: depending on the agency, that might be paid search and LinkedIn, SEO and content, account-based marketing, outbound or all of these. The best ones are judged on pipeline, customers and acquisition cost rather than traffic or leads.
How much does a B2B SaaS marketing agency cost in the UK?
Prices range from a percentage of ad spend, commonly 10–20% with a monthly minimum, to retainers of £8k–£12k a month for full demand-generation agencies such as Gripped, plus your media spend. Many agencies don’t publish prices, so ask for a written scope before you sign.
Should an early-stage SaaS company hire an agency?
Often, yes: if you’ve got a product people can sign up for or buy, and a rough idea of what a customer is worth. An agency gives you senior expertise without a full-time hire, but check it works with companies at your stage: some specialists only take on businesses above a set ARR.
Is it better to hire a SaaS specialist or a general PPC agency?
A specialist understands trials, demos, sales cycles and CRM data from day one, which matters more in SaaS than in most sectors. A strong generalist can do the job too, if they measure on pipeline and revenue rather than leads.
What is the difference between paid media and demand generation agencies?
A paid media agency runs your advertising: search, LinkedIn, paid social. A demand-generation agency usually covers a wider remit, such as strategy, ABM, content, SEO and sometimes your website, with paid media as one part. The wider remit costs more, so it makes sense when you need all of it.
In short
The best B2B SaaS marketing agency is the one built for your growth engine and your stage. Decide whether you need paid media, full demand generation, organic search or outbound, check the agency works with companies your size, and judge them on pipeline, CAC and payback, not leads or clicks.
