Full-funnel growth expertise

Growth marketing experts should improve outcomes across the whole journey, not just optimise clicks. We map your AARRR funnel, quantify where value is lost, and build a prioritised backlog of experiments. That includes acquisition testing across paid and organic, conversion rate optimisation on landing pages and flows, and lifecycle programmes that drive activation and reduce churn. Every test has a hypothesis, success metric, and decision rule so learning compounds and the team stays focused on impact.

AARRR funnel and constraints

Identify the biggest leak across acquisition, activation, retention, revenue, and referral, so work focuses on the one change that unlocks scale.

Hypothesis-led experimentation

Turn ideas into testable hypotheses with success metrics, then run rapid iterations so you stop guessing and start compounding validated learnings.

Unit economics guardrails

Optimise toward CAC payback, LTV, and cohort quality, so growth is profitable and resilient when platforms, auctions, and competitors shift.

How we deliver

We operate as an embedded growth pod with a weekly sprint cadence. You get a shared backlog, clear owners, and measurable outputs every week, such as new creatives, campaign experiments, landing page variants, lifecycle journeys, and tracking improvements. We review results, document learnings, and decide what to scale, iterate, or stop. This creates consistent momentum and avoids the stop-start pattern common with fragmented agency support.
  • Weekly sprint delivery cadence
  • Clear owners and outputs
  • Learning compounds each sprint

Acquisition across channels

We build acquisition using a mix of demand capture and demand generation. That typically includes paid search and paid social with disciplined testing, plus SEO and content that compound over time. We treat creative as a primary lever, producing and iterating continuously so performance does not plateau. Where possible, we use first-party and zero-party data to improve targeting and lead quality, while keeping measurement practical in a privacy-first environment.

Paid media testing structure

Separate intent, audiences, and creative angles so you can scale winners cleanly and avoid messy learning that slows optimisation.

Creative production at pace

Ship new hooks and formats weekly, then expand winning messages across channels to prevent fatigue and keep CPAs stable as you scale.

SEO and content for demand capture

Build landing pages and topic clusters that match buyer intent, improving organic visibility and raising conversion rates through stronger message match.

Scale acquisition

CRO, retention, and expansion

Acquisition is only half the job. We improve outcomes after the click by running CRO tests on landing pages and key journeys, using behaviour and funnel data to remove friction. Then we build lifecycle systems across email, SMS, and in-product messaging to improve activation and reduce churn. For subscription and SaaS models, we also design expansion mechanics such as upgrade prompts and segmented offers, measured through cohorts so improvements translate into higher LTV and faster payback.

CRO with clear hypotheses

Run tests on message match, UX, and offers, improving conversion rate so you can scale spend without paying more for each customer.

Lifecycle journeys by behaviour

Trigger onboarding, reactivation, and win-back flows from user actions, improving retention while keeping frequency and relevance under control.

Expansion and monetisation mechanics

Identify high-value cohorts and create upgrade paths that feel helpful, increasing revenue per customer and improving LTV:CAC at scale.

Lift conversion

What we measure

We measure performance using metrics that reflect business health. That includes CAC and payback, conversion rates through key steps, activation and retention cohorts, and LTV. We align tracking across analytics and CRM so you can see lead quality and revenue, not just platform conversions. Where attribution is uncertain, we use cohort analysis and structured tests to validate lift. Reporting stays clear and action-oriented.
  • CAC payback and LTV
  • Cohort-based retention reporting
  • Revenue-linked funnel visibility

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.

What are growth marketing experts responsible for end to end?
Growth marketing experts own the full funnel, from acquiring qualified traffic to improving conversion, activation, retention, and expansion. They map the customer journey, identify the biggest constraint, and run experiments that move the metric that matters most. That includes channel strategy, creative testing, CRO, lifecycle messaging, and measurement. The focus is sustainable unit economics, not just more leads or impressions.
How do you choose the right growth marketing experts for us?
Start by confirming they can operate beyond one channel. Ask how they diagnose funnel constraints, what metrics they optimise to, and how they prove impact when attribution is messy. Look for a clear operating cadence: a prioritised backlog, weekly shipping, and decision rules. If they cannot explain how they will improve conversion and retention as well as acquisition, you are likely buying activity, not outcomes.
Which metrics should growth marketing experts optimise first?
It depends on your constraint, but we generally optimise toward CAC payback and LTV while monitoring conversion rates through the funnel. If acquisition is expensive, conversion and payback are immediate levers. If churn is high, retention and activation become priority. We avoid over-focusing on ROAS in isolation. Cohort quality, payback period, and retention curves are better indicators of scalable growth.
How many experiments should we run, and how fast?
Experiment volume should match your data and implementation capacity. We prefer fewer, higher-impact tests with clear hypotheses over running many small changes that do not matter. A typical cadence is weekly shipping with a prioritised backlog. Some tests run in parallel across creative, landing pages, and lifecycle, while larger changes may take longer. The key is consistent learning and clear decisions to scale, iterate, or stop.
How do growth marketing experts improve paid channel performance?
We improve paid performance by tightening targeting and measurement, then scaling through creative and offer iteration rather than only bid tweaks. That includes structured campaign segmentation, disciplined testing, and ongoing creative rotation. We also focus on post-click conversion. Better landing pages and onboarding lift conversion rate, which lowers CAC and improves payback. This is usually the fastest way to scale without CPM and CPC inflation breaking efficiency.
What is your approach to CRO and landing page optimisation?
We run CRO with a clear hypothesis tied to a measurable metric, such as lead conversion rate or checkout completion. We use behavioural signals like drop-off points to find friction, then test message match, proof, offer framing, and form or flow changes. We prioritise changes that can deliver meaningful uplift quickly. Improving conversion rate makes every channel more efficient and often unlocks the next stage of scaling.
How do you improve retention and reduce churn in practice?
Retention work starts with activation. We identify the behaviours that predict long-term value, then improve onboarding so more users reach that point quickly. After that, we build lifecycle journeys triggered by behaviour to re-engage users at the right time. Segmentation and frequency control keep messaging relevant. Success is measured through cohorts and LTV, not open rates, so retention improvements translate into better unit economics.
How do you handle attribution and prove incremental growth?
We align tracking across analytics and CRM, then use funnel reporting and cohort outcomes to understand quality. When last-click attribution is unreliable, we look for consistent movement in conversion, retention, and payback. Where decisions require higher confidence, we use structured experiments, such as campaign split tests or holdouts, to estimate incremental lift. The goal is decision-grade measurement without slowing down execution.
What do we get from Growthcurve growth marketing experts?

We ship in weekly sprints, integrate like internal staff, and share progress via a real-time dashboard. Unlimited creative production is included, and we do not charge commission on ad spend. Engagement is monthly rolling, so you keep flexibility while maintaining momentum. Book a call

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.
