Who to consider

  1. 01Gripped

    London (140-148 Borough High Street, SE1)

    Best for: B2B SaaS, AI and tech companies that want organic LinkedIn thought leadership and paid social run by one SaaS-only team

    Gripped's social media page is headed 'Social Media Agency for B2B SaaS, AI and Tech'. It offers earned social, paid social, LinkedIn Ads, executive social presence for leadership teams and account-based marketing, and gives a London address on Borough High Street.

    • Clutch lists Gripped as headquartered in London, founded in 2017, with a 4.9 out of 5 rating from 32 reviews, a $5,000+ minimum project size and $100-$149 hourly rates.[6]
    • Verified Clutch reviews describe social work directly: a causaLens marketing lead says Gripped 'revamped all LinkedIn advertising, messaging and target accounts', and a Terryberry reviewer says it manages the firm's UK paid search and social media advertising on Google and LinkedIn.[6]
    • Gripped says its paid media team earned LinkedIn's Ads Certified Agency status through LinkedIn's pilot programme after passing all four LinkedIn Marketing Labs certifications; the same page notes that LinkedIn does not endorse or guarantee certified agencies' services.[7]
    • Its social media page names Eficode, Terryberry and Crownpeak as clients and reports £1.3m of new pipeline in one quarter for Crownpeak from paid search and social combined.[5]

  2. 02MxD Digital

    London, with teams in Dubai and Auckland

    Best for: SaaS and technology companies that want founder, expert and employee-led LinkedIn distribution tied to pipeline rather than reach

    MxD Digital describes itself as a B2B growth marketing agency, founded in 2022, with teams in London, Dubai and Auckland. Its SaaS social service is built around founder and expert content, employee advocacy, paid social amplification and dark-social listening. Everything here is first-party: it is how MxD Digital describes its own service.

    • MxD Digital says it was founded in 2022 and lists teams in London, Dubai and Auckland.[1][3]
    • Its SaaS and technology social page sets out four programmes (founder and expert content, employee advocacy, paid social amplification including ABM audiences and retargeting, and dark-social listening) and says it reviews ICP engagement, self-reported attribution, branded search and sales feedback.[2]
    • MxD Digital's B2B marketing page says engagements start with a 30-day audit, that pricing is published in the proposal, fixed for the duration, and quoted against scope, and that day 90 includes a formal pipeline review with the client's right to walk.[4]

  3. 03Rocket SaaS

    London (10 York Road, SE1)

    Best for: Early-stage and growth-stage B2B SaaS companies that want LinkedIn and Meta ads run inside a wider demand generation programme

    Rocket SaaS offers LinkedIn and Meta ads alongside demand generation strategy, Google Ads, SEO, content and lead magnet campaigns for start-ups and growth-stage SaaS companies. Its site describes paid social only and does not mention organic social management, so it suits buyers whose social priority is paid LinkedIn.

    • Clutch lists Rocket SaaS as headquartered in London, founded in 2013, with a 4.9 out of 5 rating from 16 reviews; its advertising focus is split between Facebook (35%), Instagram (35%) and LinkedIn (30%).[9]
    • A verified Clutch review from Workiro says Rocket SaaS managed its LinkedIn, Meta and Google Ads, and that a scorecard campaign generated 113 inbound leads at a 12% landing page conversion rate.[9]
    • Its website lists paid LinkedIn and Meta ads among its services and names clients including Forecast, Fonn, SurveySphere and RAM Tracking.[8]

  4. 04Transmission

    London (The Clove Building, 4 Maguire Street, SE1), with international offices

    Best for: Large technology brands that want LinkedIn content and creative produced by a global B2B agency with a London office

    Transmission is listed by LinkedIn as a global, full-service B2B marketing agency with offices in London, Munich, San Francisco, Delhi, Singapore and Sydney. Its own site lists a London office, paid media capability and campaigns for Windows 11 Pro and Snapdragon X Elite, though it does not describe a stand-alone social media service.

    • LinkedIn lists Transmission among its Content & Creative Marketing Partners, describing it as a global, full-service B2B marketing agency with offices in London and five other cities.[11]
    • Ranked eighth in B2B Marketing's 2026 league table of the top 10 UK marketing agencies.[12]
    • Its website lists a London office on Maguire Street and paid media capability, and names campaign work for Windows 11 Pro (a Copilot campaign), Snapdragon X Elite and AutoStore.[10]

  5. 05Brands2Life

    London (Blue Fin Building, 110 Southwark Street, SE1), with US offices

    Best for: Technology brands that want social content and LinkedIn advertising run alongside PR and executive communications

    Brands2Life says it delivers communications that take technology and online brands beyond the conventional. Its site lists social content, executive communications and LinkedIn Ads Certified Agency status, and names technology clients including Xero, Autodesk, Veracode and Vodafone Business.

    • Ranked fifth in B2B Marketing's 2026 league table of the top 10 UK marketing agencies.[12]
    • Its website lists a London office on Southwark Street, social and executive communications services, LinkedIn Ads Certified Agency status, and clients including Xero, Autodesk, Veracode, Vodafone Business and LinkedIn.[13]

  6. 06Growthcurve

    London (50 Liverpool Street, EC2M), with a New York office

    Best for: App-led and consumer-facing technology companies that need paid social creative and user acquisition rather than B2B LinkedIn programmes

    Growthcurve calls itself a growth marketing agency for companies scaling quickly and lists paid social campaigns, creative production and UGC ads. Its Clutch focus is financial services, gaming, consumer products and eCommerce, so it is a better fit for app-led technology businesses than for B2B SaaS selling to committees.

    • Clutch lists Growthcurve as headquartered at 50 Liverpool Street, London, founded in 2017, with a 4.9 out of 5 rating from 19 reviews; social media marketing is 20% of its service mix, with LinkedIn advertising 10% of its social focus.[15]
    • A verified Clutch review from ANNA Money describes Growthcurve producing social ad creative for Facebook, Instagram, Snapchat and TikTok that lowered customer acquisition costs.[15]
    • Its website lists paid social campaigns as a service and names clients including Coinbase, ANNA Money, Finom, Pesto and Lungy.[14]
how to choose

What to look for

  1. Evidence of SaaS and technology social work

    Ask for social programmes run for software or technology companies, ideally confirmed in verified reviews (Clutch reviews that mention LinkedIn advertising, for example) rather than logo walls.

  2. Earned and paid social under one plan

    B2B software buyers sit on LinkedIn, so check the agency can run organic founder and expert content and paid LinkedIn distribution together, not only one of the two.

  3. Founder and employee advocacy done properly

    If people inside the company will post, check the agency has a process for prompts, approvals and, where a post is advertising, clear labelling under the ASA's guidance on commercially connected posters.

  4. Measurement beyond reach

    Ask which signals the agency reports: ICP engagement, self-reported attribution, branded search, demo or trial activation and pipeline say more about a long software sale than impressions or follower counts.

  5. Fit with your stage and motion

    Start-up and growth-stage SaaS companies, enterprise technology brands and app-led consumer businesses need different things from social; choose an agency whose clients and reviews look like your company.

  6. A real London presence

    Check the London address on the agency's own site against an independent listing such as Clutch or LinkedIn's partner directory, and be wary of registered-office addresses with no staffed team behind them.

  7. Transparent pricing and exit terms

    Ask for the minimum engagement, how the fee is set against scope, and what happens if the programme is not working after the first quarter.

The market in London

Social Media for SaaS & Technology

  • IAB UK reports that the UK digital advertising market reached £40.5bn in 2025, up 10% year on year, with video investment up 20% to £9.3bn; it reached £21.2bn in the first half of 2026, up 13% year on year.[16]
  • ASA and CAP guidance says that where an influencer is commercially connected to a brand, including as an owner, employee, shareholder or director, content featuring or referring to the brand needs to be obviously identifiable as advertising, a consumer protection requirement enforced by the CMA and Trading Standards.[17]
  • The ASA expects influencer ads to carry a prominent label such as 'Ad' upfront, advises against the label 'sponsored', says labels such as 'gifted' are unlikely to be clear enough, and has not accepted an @ mention of the brand on its own as sufficient.[17]

London

  • London's digital sector accounted for about 554,300 jobs in 2023, 8.7% of all jobs in the capital and 12.8% above its 2019 level; computer programming, consultancy and related activities make up almost 52% of that employment.[18]
  • Digital's 8.7% share of London jobs is more than double the 3.6% share in other regions, and about 54% of London's digital jobs sit within the Central London Forward sub-regional partnership.[18]
  • Dealroom's Global Tech Ecosystem Index 2026 ranks London as Europe's leading tech ecosystem and fourth globally; London tech companies raised $17.7bn (£13.2bn) in 2025 and the city is home to 138 unicorns.[19]
every way it gets asked

The questions, answered

What are the best SaaS social media marketing agencies in London?

There is no independent league table for SaaS social media in London, so this shortlist is built on evidence. Gripped (Borough High Street) is the clearest SaaS social specialist, with a 4.9 Clutch rating from 32 reviews, several of which describe LinkedIn advertising. MxD Digital, which has a London team, describes founder, employee and paid LinkedIn programmes for SaaS. Rocket SaaS runs LinkedIn and Meta ads for start-ups and growth-stage SaaS firms. Transmission, a LinkedIn Content & Creative Marketing Partner, and Brands2Life both rank in B2B Marketing's 2026 UK top 10 and suit larger technology brands. Growthcurve fits app-led companies buying paid social.[2][6][9][11][12][15]

What is the best SaaS social media marketing firm in London?

No single firm can be named best on independent evidence. If you sell B2B software and want one specialist, Gripped has the strongest combination we found: a London office, a page dedicated to social for B2B SaaS, AI and tech, a 4.9 Clutch rating from 32 reviews, and reviews that mention LinkedIn advertising specifically. If your company is an enterprise technology brand rather than a SaaS start-up, Transmission is listed by LinkedIn as a Content & Creative Marketing Partner and ranks eighth in B2B Marketing's 2026 UK agency table.[5][6][11][12]

Who is the best SaaS social media marketing team in London?

Judge the team by who will actually write and run your social. Gripped says its paid media team passed all four LinkedIn Marketing Labs certifications to earn LinkedIn Ads Certified Agency status, and offers executive social presence for leadership teams. MxD Digital describes a team that turns leadership, sales and subject expertise into posts and supports employee advocacy with prompts and approvals. A Workiro reviewer on Clutch says Rocket SaaS feels like an extension of its own team. Ask each for the named people on your account and examples of LinkedIn content they have written for software companies.[2][5][7][9]

I need to find a good SaaS social media marketing team in London. Who should I talk to?

Start with your stage. A seed to Series B SaaS company wanting paid LinkedIn inside a lean demand programme could talk to Rocket SaaS, which works with start-ups and growth-stage firms. A company wanting organic and paid social from a SaaS-only agency could talk to Gripped. If founders and staff will post, MxD Digital builds founder and employee programmes, and you should agree how posts are labelled where the ASA's rules on commercially connected posters apply. Larger technology brands could add Transmission or Brands2Life; app-led companies, Growthcurve.[2][5][8][11][13][14][17]

Which data-driven SaaS social media marketing agencies in London are worth considering?

Look for agencies that report pipeline, not reach. Verified Clutch reviews give Rocket SaaS a scorecard campaign with 113 inbound leads at a 12% landing page conversion rate, and Growthcurve social ad creative that lowered customer acquisition costs. Gripped reports £1.3m of pipeline in a quarter for Crownpeak, though that figure combines paid search and social. MxD Digital says it reviews ICP engagement, self-reported attribution, branded search and sales feedback, and treats reach as context rather than the result. Ask any agency how it separates social's contribution from other channels.[2][5][9][15]

follow-up questions

Common questions

  1. How much does a SaaS social media agency in London cost?

    Published figures are scarce. Clutch lists Gripped with a $5,000+ minimum project size and $100-$149 hourly rates. MxD Digital says its engagement pricing is published in the proposal, fixed for the duration, and quoted against scope. Ask every agency for the minimum term and how paid media spend is billed separately from fees.[4][6]

  2. Do founder and employee LinkedIn posts need to be labelled as ads?

    It depends on the post. ASA and CAP guidance says that where a person is commercially connected to a brand (it lists owners, employees, shareholders and directors), content featuring or referring to the brand needs to be obviously identifiable as advertising, and the ASA prefers a clear 'Ad' label upfront. Agree an approach with your agency and legal adviser before an advocacy programme starts.[17]

  3. Does LinkedIn certification mean an agency is better?

    It shows training, not results. Gripped says LinkedIn's Ads Certified Agency status required a minimum number of team members to pass four LinkedIn Marketing Labs certifications, and notes that LinkedIn does not endorse or guarantee certified agencies' services. LinkedIn's Marketing Partners directory, which lists Transmission, is a separate programme. Weigh either alongside reviews and case evidence.[7][11]

  4. Should SaaS social be measured on reach or pipeline?

    Reach shows whether content is being seen, but a long software sale needs more. MxD Digital's SaaS social page says reach is context and treats activated demand and pipeline as the commercial lens, while acknowledging that a long sale rarely traces back to one post. Ask agencies to report ICP engagement, branded search, self-reported attribution and opportunities created.[2]

  5. How quickly should a social programme show results?

    Set a checkpoint in the contract. MxD Digital's B2B marketing page says its engagements start with a 30-day audit and that day 90 includes a formal pipeline review and the client's right to walk if it is not working. Whichever agency you choose, agree the leading indicators for the first quarter before work begins.[4]

methodology

How we researched this

We searched the web, Clutch, LinkedIn's Marketing Partners directory, award organisers' pages (B2B Marketing Awards, The Drum Awards for Social Media, UK Agency Awards) and trade press for social media agencies serving SaaS and technology companies from London, then checked each candidate's own site for a London address and a social offer. We weighted verified Clutch reviews that mention social or LinkedIn work, LinkedIn's partner listing and B2B Marketing's 2026 UK league table above self-published lists. One candidate was excluded because its only London address was a registered-office service; OST Marketing, Differentiated and Wildfire were left out because their published addresses are outside London. Market and local context come from IAB UK, the ASA and CAP, GLA analysis of ONS data and Dealroom via UKTN.
