Your full-funnel growth engine

Startup growth is not one channel, it is a system that compounds. We build an AARRR-led operating cadence across acquisition, activation, retention, revenue and referral, tied to a clear north star metric. That means aligning creative, media buying, SEO, lifecycle and CRO so each stage of the funnel reinforces the next. You get a prioritised backlog, weekly shipping, and a simple decision framework for scaling winners and killing losers quickly.

Acquisition across paid and organic

Build demand with short-form video, founder POV, programmatic SEO and high-intent search. Pair with paid search and paid social for demand capture, using clean audience strategy and rapid creative iteration.

Activation that lifts conversion rates

Improve the first key action with CRO, tighter landing page messaging, and nurture triggered by behaviour. Use tests, heatmaps and session replays to remove friction and increase demo, trial or checkout completion.

Retention and referral loops

Turn customers into a growth channel with referral mechanics, community-led programmes and lifecycle messaging. Use cohort insights, churn risk signals and win-back flows to expand LTV before scaling spend.

See how it works

From ideas to shipped tests

Early-stage teams often get stuck in planning, or run disconnected experiments that do not compound. We set up a simple growth operating system: one north star, clear funnel metrics, a prioritised backlog and a weekly testing cadence. You will know what is being tested, why it matters, and what decision each result unlocks. This keeps startup growth moving even when priorities and channels change quickly.
  • Weekly testing cadence
  • Backlog tied to outcomes
  • Decisions documented and repeatable

Measurement that guides spend

When attribution is wrong, teams over-invest in what looks good and under-invest in what actually drives growth. We upgrade tracking and reporting so you can see performance by funnel stage, channel and cohort, then make decisions with confidence. Expect a practical mix of platform reporting, first-party data and experimentation, including holdouts where it makes sense. You also get a real-time performance dashboard and a clear weekly rhythm for review and action.

Attribution and incrementality basics

Set up reporting that matches how you grow: pipeline, activated users, retention and revenue. Validate with controlled tests so you can separate real lift from last-click bias and platform over-crediting.

Privacy-first, post-cookie tracking

Strengthen first-party event capture and consent, and improve signal quality with server-side approaches when needed. This keeps optimisation stable as third-party identifiers disappear and policies tighten.

Clear insight for the whole team

Unify growth reporting into a dashboard that founders and operators can trust. Tie weekly decisions to outcomes like payback and LTV:CAC, not only channel-level vanity metrics.

Audit my analytics

Creative velocity at scale

In 2026, creative and positioning change faster than media algorithms. We run a creative system designed for learning: new angles, hooks, formats and offers shipped every week, tracked by concept so the team knows what is truly working. Unlimited ad creative production is included, and our specialists scale winners across Meta, Google, TikTok and beyond. The result is faster iteration without the overhead and inconsistency of juggling freelancers.

Testing by angle, not by ad

Build a hypothesis backlog from customer research, sales calls and performance data. Test hooks, proof, objections and offers systematically, then roll winners into new variants instead of starting from scratch.

Founder-led and community-led demand

Use founder POV content, behind-the-scenes narratives and micro-community programming to drive organic discovery. Repurpose winners into ads, landing pages and nurture so the message stays consistent across the funnel.

Partner-ready channel execution

As official agency partners for key platforms, we follow best practice on structure, tracking and creative specs. This reduces delivery issues and shortens the time from idea to scalable spend.

Fix my creative

Built around unit economics

Raising money or scaling headcount does not fix a leaky funnel. We focus on the unit economics investors care about: CAC, payback, LTV, churn and expansion. That means prioritising activation and retention work alongside acquisition, and aligning marketing with sales and product so handoffs are clean. Our specialists have helped scale startups to large valuations, using evidence-led iteration rather than gut feel.
  • CAC and payback focus
  • Retention before aggressive scale
  • Aligned marketing and sales

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.

Scale without hiring risk

Hiring a full growth team can take months and costs a lot before you see output. Freelancers are faster, but often unreliable and disconnected across creative, media and analytics. Growthcurve gives you a complete marketing department in one package, integrated into your workflows, with resources that flex up or down. You stay on a monthly rolling basis with no commission on ad spend, so the model stays efficient.
  • Monthly rolling engagement
  • Team scales with demand
  • 10x cheaper than hiring
What does startup growth actually include end to end?
Startup growth covers the full funnel: demand creation, demand capture, conversion, retention and referral. In practice that spans positioning, creative and content, paid media, SEO, CRO, lifecycle email and SMS, plus measurement and reporting. The aim is to improve unit economics, not just traffic. We tie work to a north star metric and supporting metrics like CAC, payback, activation rate, churn and expansion.
How do we choose a North Star Metric?
A good North Star Metric reflects delivered value and predicts revenue. For B2B it might be activated accounts or qualified pipeline; for B2C it could be repeat purchase rate or weekly active buyers. We pick one that is measurable, not easily gamed, and aligned across teams. Then we map leading indicators for acquisition, activation and retention so each experiment clearly ladders up to the North Star.
When should we scale paid media versus fix retention?
If retention or activation is weak, scaling spend often inflates CAC and worsens payback. We look at cohort retention, conversion rates and gross margin to judge whether you are ready to scale. A simple rule is to fix the biggest bottleneck first. Often that means improving onboarding, offer clarity or landing page conversion before increasing budget, so new acquisition converts and stays.
Which channels matter most for growth in 2026?
It depends on your ICP and buying behaviour, but most startups need a balanced mix. Demand creation is increasingly driven by short-form video, founder-led content, community and SEO, while demand capture comes from high-intent search and retargeting. We avoid spreading you thin. The approach is to test a small set of channels, find efficient winners, then expand distribution into adjacent channels like partnerships, newsletters or creator collaborations.
How do you run experimentation without causing chaos?
We set a clear operating cadence: weekly planning, daily execution, and a review where each test has a hypothesis, owner, timeline and decision rule. This keeps speed high without random activity. We also separate exploration from exploitation. Early tests find signals; later tests scale proven concepts. Everything is tracked in a backlog so learning compounds and new team members can ramp quickly.
How do you measure growth without over-trusting attribution?
We combine practical attribution with validation. Platform and analytics reporting helps with day-to-day optimisation, but we also use holdouts, geo splits or budget experiments where possible to estimate true lift. We prioritise first-party events and clean funnel definitions so the business can trust numbers. Reporting focuses on outcomes like activated users, pipeline, revenue and retention rather than impressions or clicks.
Can you support product-led growth and freemium funnels?
Yes. For PLG, we focus on activation and the path to the magic moment, then design lifecycle messaging and in-product prompts that increase time-to-value. We also test pricing and packaging, and improve upgrade flows. Measurement typically includes cohort retention, feature adoption and conversion to paid. This ensures growth is driven by product value rather than paid spend alone.
What is included in Growthcurve's growth team?
You get a cross-functional team covering strategy, paid media, creative production, analytics, and conversion rate optimisation, with the ability to add or reduce specialists as needs change. We integrate into your existing tools and workflows and provide a real-time performance dashboard. Unlimited ad creative production is included, and we do not charge commission on your ad spend.
How quickly can we start, and what happens first?
We can typically start quickly because you are not waiting to hire multiple roles. The first phase is a fast diagnostic: funnel performance, tracking, creative, channel mix and ICP clarity. Then we agree priorities, set metrics, and launch the first wave of experiments across acquisition and activation. You should expect early signal within weeks, while retention and SEO gains compound 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.
