User Acquisition That Scales CAC Down, Not Up
We build full funnel acquisition systems that increase volume while protecting payback, conversion rates, and downstream retention quality.
Evidence-led growth decisions
Unlimited creative production included
No commission on spend
Full funnel acquisition plan
User acquisition is not one channel, it is a system that moves people from awareness to activation and beyond. We map your funnel stages, define conversion events and micro conversions, and choose the channel mix that fits your model. That can include paid social, search, SEO, affiliates, creators, programmatic, and retargeting, supported by landing page conversion optimisation. You get a clear testing roadmap, weekly shipping cadence, and measurement tied to CAC, payback, and retention quality.
TOFU reach and discovery
Drive awareness via paid social, SEO, and targeted prospecting, optimising for efficient reach, strong hooks, and click quality rather than empty impressions.
MOFU nurture and intent
Use retargeting, email drips, webinars, and lead magnets to turn interest into consideration, tracking micro conversions and diagnosing drop-off across the journey.
BOFU conversion and checkout
Improve conversion with landing page tests, clearer offers, and reduced friction, then use personalised CTAs and remarketing sequences to close efficiently.
Acquisition beyond one channel
User acquisition breaks when it depends on a single platform. CPMs rise, fatigue hits, and growth stalls. We diversify acquisition with a full funnel approach across paid, organic, and lifecycle, while keeping one measurement framework. That means the top of funnel is built to create demand, the middle is built to educate and qualify, and the bottom is built to convert with minimal friction. The outcome is more stable growth and clearer levers to pull when results change.

- More stable acquisition performance
- Clear levers by stage
Creative and testing velocity
Acquisition plateaus are usually creative plateaus. We build a creative engine that produces and tests enough variants to keep algorithms learning and audiences fresh. That includes platform-native assets like short-form video hooks, UGC-style edits, statics, and landing page message match. We run structured experiments rather than random variations, and we rotate creatives to prevent fatigue as frequency increases. Unlimited ad creative production is included, so velocity does not depend on internal bandwidth.
Hook and angle testing
Test multiple first-three-second hooks and value props per audience, so you quickly identify what drives attention, click quality, and conversion.
Offer and CTA iteration
Refine offers and calls to action by funnel stage, using controlled tests to improve conversion rates without needing to increase spend.
Fatigue monitoring and refresh
Track frequency and performance decay, then refresh creatives and sequences before CPA rises, keeping scaling stable over longer periods.
Tracking, attribution, and lift
Modern user acquisition requires measurement that survives privacy changes. We validate your conversion events, UTMs, and funnel reporting, then improve resilience with server-side tracking where appropriate. We track both micro conversions and revenue outcomes, and we use cohort and LTV analysis to avoid optimising for low-quality users. When decisions are high stakes, we use practical incrementality approaches like geo holdouts to separate true lift from correlation. Reporting is delivered through a real time performance dashboard.
Server-side tracking setup
Improve event capture and match quality by implementing server-side tracking where relevant, reducing data loss and stabilising optimisation signals.
Multi-touch and cohorts
Use attribution and cohort views together, so you understand both the path to conversion and the quality of users acquired over time.
Incrementality validation
Run lift checks like holdouts when needed, so you scale the channels that create real growth rather than those that take credit.
Speed, talent, and cost
Building an in-house user acquisition function is slow and expensive: you need media buyers, creatives, analysts, and CRO support. Growthcurve gives you a complete marketing department in one package, with access to top US and UK talent and a team that integrates as internal staff. You can scale resources up or down and avoid the inconsistency of freelancers. The engagement is monthly rolling, so you keep flexibility while moving faster than traditional agency setups.

- Scale resources on demand
- Monthly rolling flexibility
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.
Optimise for real growth
Acquisition looks great until you realise the users do not retain, pay, or expand. We optimise for real growth by connecting acquisition decisions to downstream metrics like payback, cohort retention, and LTV. You also get proprietary AI marketing tools and a real time dashboard to keep teams aligned and reduce guesswork. With no commission on ad spend and unlimited creative production, we can test aggressively while keeping incentives focused on outcomes rather than budget size.
- Optimise to LTV, not vanity
- AI tools speed iteration
- No commission on spend
What is user acquisition and what does it include?
User acquisition is the set of activities that bring new users into your product, app, or website and move them towards a first conversion. It includes top of funnel discovery, mid-funnel nurture, and bottom funnel conversion, plus the measurement that connects spend to outcomes.
It is not only buying traffic. It also includes creative, landing pages, onboarding touchpoints, and the systems that turn attention into activated, retained users.
Which channels work best for user acquisition today?
The best channels depend on your audience, unit economics, and sales motion. Common levers include paid social, search, SEO, creators and affiliates, and retargeting, supported by email and lifecycle messaging.
We typically balance demand capture with demand creation so you are not dependent on a single platform. The right mix is proven through testing, then scaled based on CAC payback, conversion rates, and retention quality.
How do you calculate CAC and what target is realistic?
CAC is total acquisition spend divided by the number of new customers or activated users, depending on your definition of success. The right target is set by gross margin, payback window, and lifetime value, not by an industry average.
We align on a clear CAC definition, then track leading indicators that move it: conversion rate, creative performance, and funnel drop-off. This makes CAC a controllable outcome rather than a mystery number.
How do you connect user acquisition to LTV and retention?
Acquisition is only valuable if users retain, pay, or expand. We segment performance by cohort so you can see whether certain channels or creatives bring higher quality users, not just more users.
We also connect acquisition messaging to onboarding and lifecycle so expectations match reality and early churn reduces. When possible, we use LTV to guide optimisation, so scaling does not come at the cost of long-term profitability.
What is the difference between ROAS and blended efficiency?
ROAS measures revenue attributed to a specific channel divided by spend in that channel. Blended efficiency looks at total revenue and total marketing spend, which is often more stable when attribution is imperfect.
We use both views. Channel ROAS helps optimise within platforms, while blended metrics like MER or payback help decide overall budget and channel mix. This prevents over-scaling channels that take credit but do not create incremental growth.
How do you handle attribution in a privacy-first world?
We avoid relying on a single attribution model. We combine clean UTMs, meaningful micro conversions, and platform reporting with cohort analysis to understand both intent and downstream quality.
Where appropriate, we improve signal resilience with server-side tracking. For bigger decisions, we use incrementality methods like geo holdouts to validate lift. The goal is to make budget choices based on evidence, not on whichever dashboard looks best.
How many creative tests do we need to run weekly?
Testing volume depends on spend and audience size, but most teams under-test. Algorithms need fresh inputs, and audiences fatigue quickly, especially in competitive markets.
We plan structured batches so each week produces clear learnings. Because unlimited ad creative production is included, you can maintain a steady pipeline of new hooks, formats, and offers without your team becoming the bottleneck. We then scale what works and retire what does not.
Do you support product-led growth and referral loops?
Yes. For PLG, we optimise the path from first touch to activation and upgrade by aligning acquisition messaging with in-product value. That includes trial onboarding, lifecycle prompts, and upgrade triggers that reduce friction.
We can also build growth loops like referrals and UGC incentives when they fit the product. The aim is to increase LTV and reduce CAC over time, not to bolt on viral mechanics that do not match user intent.
What happens in the first month of user acquisition work?
We start by auditing your funnel, tracking, and existing channel performance, then define the priority constraint. You will see early execution quickly, such as creative test batches, landing page improvements, and account restructuring where needed.
We then run a weekly cadence of ship, measure, learn, and iterate, with reporting in a real time dashboard. If you want a user acquisition team that moves fast, book a call to get started.

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.
