Startup growth agency built for fast, measurable traction
Full-funnel growth across acquisition, activation and retention, measured against CAC payback and lifetime value, not hype.
What a startup growth agency does
A startup growth agency helps you build a repeatable engine for acquisition, activation and retention, not one-off campaigns. We start with a growth audit across your funnel, tracking, positioning and offer, then prioritise the highest impact opportunities. Execution runs in short sprints with clear hypotheses and success metrics aligned to AARRR. The aim is to improve unit economics like CAC, payback and LTV while proving which channels and messages can scale.
Audit the full funnel
Review acquisition channels, onboarding, lifecycle and tracking to find the constraint, so you stop guessing and focus on the highest leverage work.
Run sprint-based experiments
Ship tests weekly across creative, targeting and conversion paths, building a reliable learning loop that compounds improvements over time.
Scale what proves payback
Increase spend and effort only where CAC payback and cohort quality hold, protecting runway and making growth easier to explain to investors.
Built for startup constraints
- Faster learning, less waste
- Focus on the constraint
- Clear progress for leadership
Acquire users with efficient channels
Startups need fast signal without burning budget. We build an acquisition mix that fits your stage and model, typically combining paid social for creative and message testing, paid search for high intent capture, and SEO foundations for compounding demand. We set clear conversion events and optimise toward quality, not click volume. With unlimited ad creative production included, you can test more angles, reduce creative fatigue, and scale only what improves activated users, qualified pipeline or purchases.
Paid social creative testing
Test hooks, angles and formats across Meta, TikTok and LinkedIn, scaling creatives that improve qualified sign-ups, demos or purchases.
Paid search for intent capture
Capture buyers with clear intent using tight keyword and landing page alignment, reducing wasted spend from mismatched traffic.
SEO foundations that compound
Build technical SEO and content clusters around buyer questions, improving long-term acquisition and reducing dependence on paid budgets.
Improve activation, retention and monetisation
If activation and retention are weak, scaling acquisition only increases churn and CAC. We use funnel analysis, session replays and cohort reporting to find where users drop off, then run CRO and onboarding experiments to improve the path to value. We also build lifecycle messaging and expansion plays that increase retention and LTV. Stronger cohorts reduce payback pressure and create the financial headroom to scale spend with confidence.
Onboarding and activation fixes
Identify the key activation actions and remove friction with onboarding and product messaging experiments, so more users reach value quickly.
CRO on high-impact pages
Test landing, pricing and checkout flows with clear hypotheses and measurement, improving conversion without relying on higher spend.
Lifecycle and expansion journeys
Build behaviour-based nurture, reactivation and upsell journeys that improve cohort retention and increase revenue per customer over time.

SEO that compounds, not a checklist
Organic growth is a mix of technical hygiene, content that earns clicks, and authority building that is genuinely deserved. We treat SEO as a product, with a backlog and a cadence, rather than a one-off project. Technical work covers crawlability, site architecture, Core Web Vitals, schema markup and index management. On-page work is driven by search intent and the real questions buyers ask at each stage. Off-page focuses on link earning through useful assets, partnerships and digital PR rather than spam. For example, for a B2B brand we might build a set of comparison pages for demand capture, a small research piece to earn links, and a library of problem-led articles that support sales calls. The outcome is more qualified traffic, better brand credibility, and lower dependency on paid media over time.

Lifecycle marketing that increases LTV
If you only optimise acquisition, you end up paying more for the same customers. We build lifecycle systems that raise retention and expansion, using email, SMS where relevant, and CRM workflows that feel personal without being creepy. We set up segmentation based on behaviour and value, then design flows for onboarding, activation, replenishment, win-back and referral. In practice that can include RFM modelling for ecommerce, lead scoring for B2B, or product usage triggers for SaaS. We also help you capture first-party and zero-party data with preference centres and progressive profiling, so targeting stays resilient as privacy changes. When we ran a lifecycle audit for one team, we found revenue sitting in overlooked moments, like post-purchase education and renewal risk signals. The outcome is a healthier blended CAC and a marketing engine that keeps paying you back.
Measurement you can trust and use
Attribution arguments waste time and block good decisions. We set measurement up so it is good enough to guide spend, creative and roadmap choices, and we are honest about what is knowable. Tracking work can include GA4 hygiene, conversion event design, server-side tracking where appropriate, and consistent UTMs. Reporting lives in a real-time dashboard, with views that match how you run the business, such as channel performance, funnel conversion, cohort retention and creative learnings. We also use incrementality thinking where it matters, like geo holdouts or controlled tests for bigger budget shifts. For example, if brand search rises after a video push, we look at the whole picture rather than declaring victory based on last click. The outcome is faster iteration and fewer surprises in board meetings.
Operating rhythm, SLAs and ways of working
Good marketing is mostly good operations. We set a working rhythm that keeps delivery moving and prevents strategy decks from becoming a comfort blanket. You get a named lead, specialist channel owners, and access to top-tier US and UK talent, scaled up or down based on your needs. We agree response times, approval flows and who owns what across creative, landing pages, tracking and budget changes. Campaign planning happens in short cycles, with clear priorities and a shared backlog, so work does not disappear into a black box. We also help your internal stakeholders, like product, sales and finance, stay aligned with what marketing is doing and why. The outcome is a calm, consistent cadence, less context switching, and a team that behaves like your internal staff while staying on a monthly rolling basis.
