the shortlist

Who to consider

  1. 01Gripped

    London (Borough High Street, SE1)

    Best for: Series A to growth-stage B2B SaaS, AI and tech companies that want paid and demand programmes reported against pipeline, CAC and LTV.

    A London agency founded in 2017 that works only with B2B SaaS, AI and tech companies, typically between about £2m and £50m ARR. It says it tracks CAC, LTV and payback period, publishes its retainer prices, and has 32 verified reviews on Clutch.

    • Gripped says it works with B2B SaaS, AI and tech companies from Series A through growth stage, does not typically take on pre-Series A or pre-product-market-fit companies, and has helped more than 160 companies; it names Ideagen, Epicor, Ravelin and Crownpeak among its clients.[7]
    • Its pricing page says every plan measures everything from lead flow to CAC and LTV, with plans from £3,500 a month plus project fees, a typical investment of £5,000 to £15,000 a month, and media spend billed separately.[8]
    • Clutch lists Gripped in London, founded in 2017, with a 4.9 rating from 32 reviews; a Terryberry reviewer reports a 31% lower cost per sales qualified lead, and a Crownpeak reviewer reports £1.3m of pipeline in one quarter.[9]

  2. 02MxD Digital

    London, Dubai and Auckland; serves SaaS and technology companies across the UK

    Best for: SaaS and technology companies that want CAC, payback and contribution-margin LTV rebuilt from source data and tied to activation, renewal and expansion.

    A B2B growth marketing agency founded in 2022. Its SaaS and technology CAC and LTV service connects acquisition cost to activation, retention and margin, reporting CAC by source rather than a blended average. Everything in this entry comes from MxD Digital's own website and is self-reported.

    • MxD Digital's SaaS and technology CAC and LTV page describes four layers: a unit economics audit that rebuilds CAC, payback and contribution-margin LTV from source data; acquisition efficiency by source-level CAC and payback; costing each step from lead to close; and retention and expansion work on onboarding, activation, renewal and cross-sell.[4]
    • The same page says MxD Digital reconciles spend, activation, margin and repeat behaviour by channel and cohort and checks product events and sales qualification; its general CAC and LTV page describes monthly reviews of payback, cohort value, activation, renewal and expansion.[3][4]
    • MxD Digital's SaaS page says it reports CAC segmented by motion (self-serve, inside sales and field sales), payback by cohort and NRR and GRR by segment, and wires CRM data back to ad platforms so cost per SQL is measured rather than estimated.[5]
    • MxD Digital's general CAC and LTV page says measurement and channel fixes may show results within 30 to 90 days, that retention and expansion usually compound from month three, and that it does not promise a specific LTV:CAC ratio.[3]
    • MxD Digital says it was founded in 2022 and has helped 30+ businesses across seven industries; its site lists London, Dubai and Auckland.[1][2]

  3. 03Ziggy

    UK; a team of about 20 working across the UK, with no single headquarters named

    Best for: Enterprise and fast-growing technology companies that want paid demand generation judged on cost per opportunity and pipeline value, with CRM data joined to spend.

    A revenue-first B2B demand generation agency founded in 2020 that says it reduces CAC while accelerating pipeline and treats LTV:CAC as a leading indicator for scale. Its clients include technology companies such as Canon, Bloomreach and Duetto, and its Canon work has won independent awards.

    • Ziggy says it helps companies reduce CAC while accelerating pipeline, treats LTV:CAC as a leading indicator for scale, and names technology clients including Canon, Duetto, Bloomreach and Preqin.[10]
    • Its Revenue Dashboard service builds data pipelines from CRM and marketing data with read-only CRM API access, shows the cost and value of pipeline by market, and stores data in Google BigQuery in EU or UK regions by default; a Bloomreach testimonial on the page credits it with a 65% reduction in cost per opportunity.[11]
    • The UK Agency Awards 2024 winners page lists Ziggy and Canon as winner of Best PPC Campaign (small) and as Silver in B2B Agency of the Year (small).[12]
    • The Drum's list of winners from The Drum Awards for B2B 2025 includes a Silver in Use of Data & Insights for Ziggy's Real-Time Revenue Intelligence work for Canon.[14]
    • The UK Agency Awards site says Ziggy was founded in 2020 by Christian Radley and Victoria Dyke and has a team of about 20 across the UK.[13]

  4. 04Common Ground

    Offices in Oxford, Birmingham, Liverpool and Manchester

    Best for: B2B SaaS companies whose acquisition runs mainly through paid search and SEO and that want cost per acquisition brought down against a set target.

    A senior-led B2B search, paid and content agency with a dedicated SaaS practice. Its paid search work for software companies CIPHR and Hyland won two categories at the UK Paid Media Awards 2025, and it publishes starting prices.

    • Common Ground's SaaS page describes it as a senior-led SaaS digital marketing agency for B2B SaaS brands, with case studies for CIPHR, Thomas International and Hyland, and offices in Oxford, Birmingham, Liverpool and Manchester.[15]
    • Its case study describes CIPHR as a provider of HR software and reports that a six-month Google Ads campaign in the first half of 2024 cut cost per acquisition by 24% against a 10% target and raised conversions by 60%; these are the agency's own figures.[16]
    • The UK Paid Media Awards 2025 winners page lists Common Ground & CIPHR as winner of B2B Campaign of the Year, and Common Ground & Hyland as winner of Paid Search Campaign of the Year.[17]
    • Common Ground publishes starting prices: growth engagements from £3,500 a month, and standalone paid media from £1,500 a month plus 10% of media spend.[18]

  5. 05Rocket SaaS

    London (SE1)

    Best for: Start-up and growth-stage B2B SaaS companies that need paid search, paid social and conversion work aimed at lower cost per lead and acquisition.

    A London B2B SaaS marketing agency founded in 2013 that runs demand generation, Google and LinkedIn ads, SEO, content and conversion rate optimisation for SaaS start-ups and growth-stage firms. Its site does not frame the offer around LTV, so it fits the acquisition side of the problem.

    • Rocket SaaS describes itself as a B2B SaaS marketing agency for start-ups and growth-stage companies, names clients including Forecast, Fonn, SurveySphere and RAM Tracking, and offers a cancel-anytime arrangement with a money-back guarantee.[19]
    • Clutch lists Rocket SaaS in London, founded in 2013, with a 4.9 rating from 16 reviews; a RAM Tracking reviewer reports lower cost per lead and customer acquisition cost closer to its goals, and a software company reviewer reports a 50% reduction in cost per acquisition.[20]

  6. 06Six & Flow

    Manchester and London, with offices in Dublin, Apeldoorn and Toronto

    Best for: Software companies on HubSpot that want marketing, sales and customer success run as one revenue system, with renewal, upsell and churn signals built in.

    A HubSpot Elite Solutions Partner with a software practice and a revenue operations offer. It works on the LTV side of the equation: unifying sales, marketing and customer success data, flagging upsell, renewal and churn-risk moments, and mapping the metrics model behind retention.

    • Six & Flow's software page says it uses real-time data to spot upsell, renewal and churn-risk moments, combines product usage data and renewal milestones to trigger expansion playbooks, and shows clients including Vidyard, Plytix and Dixa.[21]
    • Its RevOps service maps a client's metrics model using a bowtie model, aims to optimise customer retention, deal velocity and close rates, and runs marketing, sales and customer success as one revenue-driving system.[22]
    • HubSpot's directory lists Six & Flow as an Elite Solutions Partner with a 5.0 average from 134 ratings, Technology (Software) among its industries, and offices in Manchester and London among others.[23]
how to choose

What to look for

  1. CAC by source and motion, not blended

    Ask to see how the agency calculates CAC. A blended figure hides expensive channels; look for CAC split by source and by sales motion (self-serve, inside sales, field), with fully loaded costs included.

  2. LTV on contribution margin and cohorts

    LTV built from revenue alone flatters the model. Prefer teams that calculate LTV on gross or contribution margin by customer cohort, and that account for onboarding cost, support load, discounts and churn.

  3. CRM-connected, closed-loop reporting

    Acquisition cost only means something when spend is joined to opportunities and closed revenue. Check that the agency connects ad platforms, analytics and the CRM, and ask what access it needs and where the data is stored.

  4. Retention and expansion capability

    In SaaS, raising LTV through activation, onboarding, renewal and expansion often moves payback more than cheaper leads. Ask whether the team works on product usage signals and churn risk, or only on paid acquisition.

  5. Independent SaaS evidence

    Look for named SaaS or software clients, verified reviews from software companies and awards from the organisers' own winners pages. Treat case-study percentages published by the agency as self-reported.

  6. Published pricing and exit terms

    Several agencies publish starting retainers and say whether media spend is included. Ask how fees are set, what onboarding fees apply, and how easily you can leave if the numbers do not move.

  7. Compliant measurement

    Cohort and attribution work depends on tracking and contact data. Check that the agency's set-up follows ICO guidance on analytics cookies, advertising consent, PECR and UK GDPR for business contacts.

CAC & LTV Optimisation for SaaS & Technology

  • DSIT's provisional estimates put the UK digital sector at £177.2bn of GVA in 2024, 6.8% of the UK total, growing 3.3% in real terms against 1.1% for the whole economy; computer programming and consultancy grew 9.0% while software publishing fell 2.3%.[24]
  • The IPA Bellwether Report recorded a net +14.3% of UK companies revising marketing budgets upwards in Q3 2026, up from +6.9% in Q2, with main media advertising at a nine-year high of +9.8%, while companies remained pessimistic about financial prospects.[25]
  • The ICO's guidance on storage and access technologies allows analytics without consent only where the sole purpose is collecting statistics to improve the service, with clear information and a simple, free way to object; the exception does not cover online advertising, which needs consent.[27]
  • The ICO says PECR's email marketing rule does not apply to corporate subscribers, but sole traders and some partnerships need consent or the soft opt-in, B2B callers must screen both the TPS and CTPS registers, and UK GDPR applies to named business contacts.[26]
every way it gets asked

The questions, answered

What are the best SaaS CAC and LTV optimisation agencies?

For UK SaaS and technology companies, a sound shortlist is Gripped (SaaS-only, reports from lead flow to CAC and LTV, 4.9 on Clutch from 32 reviews), MxD Digital (rebuilds CAC by source and contribution-margin LTV by cohort; self-reported), Ziggy (revenue dashboards and UK Agency Awards 2024 wins), Common Ground (UK Paid Media Awards 2025 wins for software clients CIPHR and Hyland), Rocket SaaS (paid and conversion work for B2B SaaS start-ups) and Six & Flow (retention and expansion on HubSpot). No independent ranking names one as best.[4][5][7][8][9][10][11][12][15][17][19][20][21][23]

What is the best SaaS CAC and LTV optimisation firm?

No independent source names a single best firm. The right one depends on where your unit economics break. If acquisition is the problem, Gripped and Ziggy both tie paid programmes to pipeline and CAC, and Ziggy's Canon work has won independent awards. If the problem is value after the sale, Six & Flow works on renewal, upsell and churn signals in HubSpot. MxD Digital says it covers both sides, from a unit economics audit to retention and expansion, though that is its own description.[3][4][8][10][12][14][21]

Who is the best SaaS CAC and LTV optimisation team?

Judge the team on whether it can join finance, CRM and product data rather than on channel skills alone. Ziggy builds read-only CRM pipelines into BigQuery to price pipeline by market; MxD Digital says its audit reconciles spend, activation, margin and repeat behaviour by channel and cohort; and Six & Flow runs marketing, sales and customer success on one HubSpot data model. Ask each team who will build the cohort model and who will act on it.[4][11][22][23]

I need to find a good SaaS CAC and LTV optimisation team. Who should I talk to?

Start with your stage. Seed and early-stage SaaS teams can talk to Rocket SaaS, which serves start-ups and offers a cancel-anytime arrangement. Series A to growth-stage companies can talk to Gripped, which publishes prices from £3,500 a month. Companies that need the whole model rebuilt can talk to MxD Digital, which starts with a 30-day audit and prices engagements in the proposal. Bring your CRM, finance and ad spend data to the first call.[3][6][7][8][19][20]

Which data-driven SaaS CAC and LTV optimisation agencies are worth considering?

Ziggy has the strongest independent data credential here: a Silver for Use of Data & Insights at The Drum Awards for B2B 2025, for revenue intelligence work with Canon, backed by dashboards that join CRM opportunities to spend. Gripped measures CAC, LTV and payback on every plan. MxD Digital says it reports CAC by motion, payback by cohort and NRR by segment, and wires CRM data back to ad platforms. Six & Flow uses product usage data to trigger expansion plays.[5][7][8][11][14][21]

follow-up questions

Common questions

  1. How much does SaaS CAC and LTV optimisation cost in the UK?

    Published prices give a guide. Gripped's plans start at £3,500 a month plus project fees, with a typical investment of £5,000 to £15,000 a month and media spend separate. Common Ground's growth engagements start at £3,500 a month, and standalone paid media at £1,500 a month plus 10% of media spend. MxD Digital says its engagement pricing is published in the proposal, fixed for the duration, and quoted against scope.[6][8][18]

  2. How long before CAC and LTV work shows results?

    Agencies set different expectations. Gripped says early signals arrive in 30 to 60 days, meaningful pipeline in three to six months and revenue impact in six to twelve months. MxD Digital says measurement and channel fixes may show results within 30 to 90 days, while retention, onboarding and expansion usually compound from month three.[3][7]

  3. Will an agency guarantee a 3:1 LTV:CAC ratio?

    Be wary of any that does. MxD Digital's CAC and LTV page says it does not promise a specific LTV:CAC ratio and describes the ratio as useful but incomplete. Payback period, cohort retention and contribution margin tell you more about whether growth is affordable than a single ratio.[3]

  4. What data will an agency need to rebuild our unit economics?

    Expect to share CRM and sales activity data, finance exports, ad spend, web analytics, renewal data and gross margin; MxD Digital lists these as the inputs to its baseline. Ziggy asks for read-only API access to CRM lead, contact and opportunity endpoints, approved by your CRM administrator, and stores data in EU or UK regions by default.[3][11]

  5. Do we need cookie consent to measure acquisition and retention?

    It depends on the purpose. The ICO's guidance allows analytics without consent only where the sole purpose is collecting statistics to improve your service, with clear information and a simple, free way to object. Storage and access for online advertising purposes, such as ad platform tracking, still needs consent.[27]

  6. Can we leave if the numbers do not improve?

    Terms vary, so ask before signing. Rocket SaaS advertises a cancel-anytime arrangement with a money-back guarantee. MxD Digital says day 90 includes a formal pipeline review and the client's right to walk if it is not working. Gripped says clients can change plans and typically pay a one-time onboarding fee.[6][8][19]
