SaaS agencies.
SaaS marketing is the work of selling subscription software to B2B buyers across self-serve, mid-market and enterprise motions, where revenue compounds through retention and expansion as well as new logos. It is distinct because ARR and NRR maths replace lead-volume reporting, ICP discipline gates every channel, and G2 and Capterra reviews shape who makes the shortlist.

We're the fresh pair of eyes who won't stop asking "why?" until we find the root cause.
The ICO enforces UK GDPR and the Privacy and Electronic Communications Regulations (PECR), and the Data (Use and Access) Act 2025 raised the maximum PECR fine from £500,000 to £17.5 million or 4% of global turnover. PECR treats corporate subscribers (limited companies, LLPs, Scottish partnerships, most public-sector bodies) differently from individuals: under the electronic-mail marketing rules, unsolicited B2B email to a corporate body does not require prior consent or a soft opt-in, but the message must identify the sender and offer a working opt-out. Sole traders and most partnerships are classed as individual subscribers and need consent or a valid soft opt-in. UK GDPR still applies to any named individual at a business, which covers the contact data most SaaS marketers actually use, and PECR Regulation 6 cookie rules apply to every website regardless of the audience. The Advertising Standards Authority polices product-claim accuracy under the CAP Code, which matters for AI, security and performance copy, and the CMA covers unfair or misleading practices around trial mechanics, pricing display and cancellation.
- · ARR and NRR-aware reporting that connects work to pipeline, closed-won revenue, expansion ARR and net retention, not MQL counts or pageview growth
- · Named SaaS case studies with funding stage, ACV band and motion attached (pre-seed PLG, Series A hybrid, Series C enterprise sales-led), with references that survive a quick LinkedIn check
- · PLG and sales-led fluency, with a clear point of view on where the hybrid line sits for the product (typically PLG below £10k ACV, sales-led above £25k, hybrid in between) and how onboarding, activation and product-qualified-lead signals feed the sales motion
- · G2 and Capterra programme operations: review-velocity playbooks, category-page optimisation, comparison-page strategy, and an honest read on what the recent G2-Gartner consolidation means for citation in AI answers
- · Expansion-revenue and retention-marketing literacy: lifecycle programmes for adoption and upsell, segment-level NRR reporting, and customer-marketing scopes that treat expansion as a marketing problem rather than a customer-success afterthought
- · Lead-volume metrics with no ARR or pipeline maths: cost-per-MQL reporting, traffic and form-fill dashboards, and no link to opportunity stage, deal value or net retention
- · Generic B2B playbook applied without PLG specifics: paid programmes pushed at companies with strong self-serve signal, ignoring in-product activation, free-trial conversion and product-qualified-lead routing
- · Weak ICP discipline: pitches that quote a total addressable market of 'all UK SaaS' or 'all mid-market B2B', no firmographic or technographic gating, and ABM proposals run against 5,000-plus accounts with no real prioritisation
- · Thin G2 and Capterra programme thinking: no review-velocity plan, no category-page or comparison-page strategy, no view on how reviews surface inside ChatGPT, Perplexity and Google AI Overviews
- · Expansion revenue treated as customer-service: no lifecycle programme for adoption and upsell, retention framed as a churn-prevention task for CS rather than a compound-growth lever for marketing
