Marketing Growth Audit

At thatsplunk digital, the Marketing Growth Audit is our way of helping ambitious brands navigate their growth challenges with precision and confidence. In a single deep dive, we review your paid media, affiliate programs, discount strategy, and customer value, identifying what’s working, what’s leaking, and where the biggest opportunities lie. You’ll walk away with a clear, actionable roadmap to scale smarter, without the noise, the guesswork, or the wasted spend.

What we do (and do well)

Audit, Analyse, Advise

We start with a structured, one-off audit to identify inefficiencies and uncover growth opportunities across your full funnel. No fluff, just sharp, actionable insights backed by data.

Fix What’s Leaking

From affiliate programs to discount code misuse, we help you clean up hidden revenue drains. Our work improves margin control, partner quality, and code governance, without hurting conversion.

Scale Smarter, Not Louder

We optimize your paid media and customer journeys to drive meaningful LTV and new customer growth. Creative, budget, targeting, we help you get more from every move you make.

  • Affiliate Tiering

    Organizing affiliates based on performance, contribution to new customer growth, and margin impact. Helps cut bloat and boost ROI by focusing on value, not volume.

  • Code Stacking

    When customers combine multiple discounts, reducing AOV and margins. We identify where it’s happening and apply logic to prevent it, without harming conversion.

  • First vs Last-Click

    Two different attribution models. We help you choose and implement the right one based on your goals (acquisition vs assist, discovery vs conversion).

  • LTV:CAC Ratio

    A critical metric for sustainable growth. We break down customer lifetime value by cohort and compare it to acquisition cost, so you know where to spend and where to scale back.

  • Post-Purchase Flows

    Automated email or SMS journeys after checkout. Often underused, these are key moments to reinforce value, upsell, and build retention. We audit and optimize the flow structure.

  • Budget Caps vs Pacing

    How your paid media budget is managed over time. We assess if your campaigns are throttled too early, underdelivering, or overspending too fast, and fix the pacing logic.

  • Incremental Uplift

    True growth isn’t about more spend, it’s about new results. We isolate what’s actually incremental, what brings net-new customers, and focus your investment there.

  • Creative Fatigue

    When ad performance drops due to repetition. We spot fatigue early in your paid campaigns and help build systems for testing and rotating creatives efficiently.

MEET THE FOUNDER

Matt Hennessy (he/him)

Growth Marketing Strategist

Guided by insight, driven by curiosity

I’m a performance marketer with 9 years of experience across agency and client-side roles, helping brands scale through smarter media buying, affiliate optimization, and LTV-focused growth.

My Journey

I began in digital marketing with a curiosity for how creative ideas and data work together. Since then, I’ve led multi-channel strategies, managed large ad budgets, built reporting systems, and restructured affiliate programs to boost ROI and clarity. Thatsplunk was born from that experience, as a way to deliver high-impact audits that give brands the insight and structure they need to grow.

Wins I’m Proud Of

I’ve turned underperforming channels into growth engines, aligned teams around shared metrics, and built processes that keep scaling on track. The key lesson? Growth comes from focusing on the few levers that matter most.

Beyond the Numbers

I’m driven by problem-solving and seeing strategy turn into results. Off the clock, you’ll find me sailing, supporting my national rugby team, or in France, exploring the culture, language, and food that inspire how I connect with people.

Our Promise

  • We primarily work with SMEs, but can support larger businesses as well. If you spend between €10k and €500k/month on marketing, we can likely help.

  • Not unless you want to. The audit is designed to stand on its own, a complete, structured review with clear takeaways. If further support makes sense after that, we can talk.

  • Audit packages start at €750. We’ll recommend the right tier based on your brand’s size and needs.

  • Some issues are quick fixes; others need time. Your audit will clearly outline both immediate wins and longer-term strategies.

  • Our work spans paid acquisition (Meta, Google, TikTok), affiliate programs, discount strategy, retention flows (email/SMS), and customer value analysis.

  • Yes. We don’t manage your accounts unless you hire us separately to do so. Our audits are advisory, you remain in control.
