Acquisition built on trust

Fintech growth marketing starts with one constraint: trust. We build acquisition systems that earn it while still moving fast, combining SEO, paid search, paid social, affiliates, partnerships, and distribution plays. We align ad-to-landing message congruence, set compliance guardrails early, and optimise towards quality conversion events. That means cost per activated user, not just cost per signup. Every channel runs through structured experiments so you can scale what is actually incremental, not what is over-attributed.

Programmatic SEO with compliance

Create structured landing pages for specific use cases, locations, or corridors, with clear disclosures and proof points that reduce friction and improve qualified signups.

Paid media optimised to activation

Optimise campaigns to activated users and downstream quality, using clean conversion events and controlled tests so spend follows real incrementality, not last-click noise.

Partnerships and embedded distribution

Build partner channels that place your product inside trusted ecosystems, reducing dependence on auctions and creating compounding acquisition from repeatable placements.

Scale acquisition

Optimised for unit economics

Fintech growth breaks when teams optimise for the wrong metric. We focus on unit economics and quality, tying marketing to activated users, retention cohorts, and payback. That means improving the full path from ad to landing to onboarding to first value, then using lifecycle to increase LTV. Our approach makes scaling decisions clearer and reduces wasted spend on traffic that never becomes profitable customers.
  • Activation-first conversion metrics
  • Payback and LTV focus
  • Less wasted acquisition spend

Personalisation and lifecycle

Most fintech teams leave growth on the table after the first signup. We build lifecycle systems that convert more of the traffic you already pay for, using micro-segmentation based on behaviour, lifecycle stage, product usage, and risk context. Then we run automated journeys across email, push, in-app, and retargeting to guide users to their next best action. This improves activation, reduces churn, and increases LTV, which is often the fastest path to better CAC payback.

Behavioural micro-segmentation

Segment users by events like funding, first transaction, frequency, and feature adoption, so lifecycle messaging is relevant and improves activation without spamming.

Triggered email and push journeys

Build compliant onboarding, reminder, and win-back flows that fire from real behaviour, improving completion rates and retention cohorts across product lines.

Referral loops with unit economics

Design double-sided referral incentives and fraud controls, measuring referral payback and retention so virality lowers CAC without harming margins or trust.

Lift retention

Content that builds authority

Fintech buyers need education and proof, especially for high-trust products. We build content engines that attract qualified demand and support conversion: pillar pages, data-led explainers, calculators, case studies, and webinar programmes that sales and lifecycle can reuse. We also adapt content for modern discovery, including answer engine optimisation and formats that travel on YouTube, social, and email. The objective is compounding organic growth and stronger conversion rates, not publishing for its own sake.

Education-led content strategy

Create practical content that answers real user questions and addresses risk concerns, improving trust and intent while supporting compliant messaging across channels.

AEO and zero-click visibility

Optimise key pages and FAQs for answer engines with clear structure and proof, increasing visibility even when users do not click through to your site.

Repurposing for distribution

Turn one core asset into multiple formats across email, social, and video so learnings spread faster and organic reach compounds without extra production burden.

Build authority

A complete growth team

Fintech growth marketing needs more than a media buyer. You need strategy, creative, analytics, SEO, CRO, and lifecycle working as one team. Growthcurve gives you a complete marketing department in one package, embedded with your team and run on a weekly cadence. It is designed to be faster and cheaper than building the equivalent in-house, with no long-term contracts and the ability to scale resources up or down on demand.
  • Embedded, senior operators
  • Scale resources on demand
  • Monthly rolling, no lock-in

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.

Speed with accountability

Fast testing only helps if you can see what is working. We pair an evidence-led approach with a real time performance dashboard and proprietary AI marketing tools, so you can move from insight to action quickly. Unlimited ad creative production keeps velocity high across channels, and we do not charge commission on ad spend. This creates a tighter feedback loop and clearer decision-making as you scale.
  • Real-time growth reporting
  • AI tools speed iteration
  • Unlimited creative, no commission
What is fintech growth marketing, in practical terms?
Fintech growth marketing is full funnel optimisation focused on measurable business outcomes: acquisition, activation, retention, and revenue. It combines channel strategy with experiments across landing pages, onboarding, lifecycle, and offers. The key difference in fintech is trust and compliance. You need clear proof, transparent messaging, and tracking that ties spend to unit economics. If you only optimise for cheap signups, you can scale the wrong audience and harm payback.
Which metrics matter most for fintech growth marketing?
The right metrics depend on your product, but they should reflect quality and payback. Common ones include cost per activated user, activation rate, retention cohorts, CAC payback period, and LTV. For B2B fintech, add pipeline velocity and SQL rate. We also track funnel leakage: where users drop from click to signup to funding or first transaction. Improving conversion at the right step can reduce CAC without increasing ad spend.
How do you optimise paid campaigns beyond cost per signup?
We optimise to downstream events that represent real value, such as funded accounts, first transaction, or qualified applications. That starts with clean conversion definitions and consistent event tracking. When scale allows, we use controlled testing such as time-boxed experiments or geo holdouts to validate incremental lift. This reduces overreliance on platform reporting and helps you allocate budget based on what actually changes outcomes, not what gets credit.
What is programmatic SEO and when does it work?
Programmatic SEO uses structured templates and data to create many landing pages targeting specific intents, such as product corridors, regions, professions, or use cases. It works when you have repeatable demand patterns and the pages genuinely help users. In fintech, it must be compliance-aware. Pages should include accurate disclosures and proof. Done well, it can compound qualified traffic over time and reduce dependence on paid media for basic discovery.
How do you personalise fintech journeys without feeling intrusive?
We base personalisation on helpful first party signals, such as lifecycle stage and product usage, not on invasive assumptions. The aim is to guide the next best action, like completing onboarding, funding, or adopting a feature. We use segmentation and triggered messaging across email, push, and in-app prompts, with frequency controls to avoid noise. Personalisation should increase clarity and confidence, which improves conversion and retention in high-trust categories.
How do referral loops work for fintech products?
Referrals work well in fintech because decisions are trust-driven and people rely on recommendations. A strong referral loop includes a clear reward, an easy sharing path, and tracking that shows referral payback. We design double-sided incentives with guardrails against abuse and measure retention and activation for referred users. The goal is to lower blended CAC without bringing in users who only want a reward and never become long-term customers.
How do you balance acquisition with retention for faster payback?
Improving retention and activation is often the fastest way to make acquisition profitable. We treat the funnel as one system: ads and SEO bring demand, onboarding converts it, and lifecycle keeps users engaged and expands value. We prioritise the biggest constraint first. If paid is working but activation is weak, we focus on onboarding and lifecycle. If retention is strong but volume is low, we scale acquisition. This approach improves payback predictably.
How do you handle compliance in fintech marketing execution?
We build compliance guardrails early by aligning on approved claims, required disclosures, and consistent language across ads, landing pages, and nurture. That reduces rework and keeps testing within safe boundaries. We are not a legal function, but we work well with internal compliance teams and keep a clean version history for faster review. The goal is to maintain speed while protecting trust and avoiding risky messaging that creates account or reputational issues.
What happens in the first month of a growth engagement?
We start with an audit of acquisition channels, tracking, landing pages, onboarding, and lifecycle. Then we build a prioritised backlog and run the first set of experiments focused on the biggest constraint. Early work typically includes conversion event cleanup, creative testing, landing page improvements, and activation flows. You will see a weekly cadence of what shipped and what we learned.

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.
