What we do
Spike delivers data-driven performance marketing across three core practice areas: analytics and measurement, paid media management, and marketing automation. On the measurement side, the team sets up GA4, server-side Google Tag Manager, attribution modelling, and custom dashboards to build a tracking foundation that informs every downstream decision.
For paid media, Spike plans, builds, and manages campaigns across Meta Ads and Google Ads (paid social and paid search), with a focus on funnel optimisation, bid strategy, and scaling ad spend profitably. The agency has tracked over 12 million euros in ad spend and reports an average 3.8x ROAS across its client base, indicating sustained campaign management rather than one-off project work.
The automation practice covers HubSpot implementation, email flows, lead scoring, and CRM integration, enabling clients to replace manual repetitive processes with scalable systems. These three pillars are designed to work together as a compounding growth engine rather than isolated point solutions.
Work follows a structured three-phase process: an audit phase to assess what is working and where money is leaking; a build phase to fix foundations, establish tracking, and launch campaigns with full documentation; and an ongoing optimise phase using clean data to drive continuous improvement across creative, audiences, and bidding. Engagements appear to be ongoing retainer relationships given the 95% client retention rate cited.
Our approach
Growth marketing at the intersection of data, design, marketing, and technology. Three-phase process: (1) Audit - honest assessment of tracking, campaigns, funnels, and data; (2) Build - fix foundations, set up tracking, build and launch campaigns with full documentation; (3) Optimise - continuous optimisation of bid strategies, audience expansion, and creative testing driven by real numbers. Full-funnel ownership across awareness, acquisition, activation, retention, referral, and revenue.
How we work
Retainer
Ongoing monthly engagement with fixed scope and regular delivery. Typically minimum 3 months.
Workshop or sprint
Intensive short-format engagement — typically 1 to 5 days — producing a specific output.
Hybrid
Combination of engagement models — typically a project fee plus ongoing retainer.
Project-based
Fixed-scope, fixed-fee engagement with defined deliverables and timeline.
Verified use cases
Companies lack reliable tracking and attribution, leading to wasted ad spend they cannot see.
GA4, server-side GTM, and custom dashboards create a measurement foundation that informs every decision.
Paid campaigns are run without precision, resulting in poor ROAS and unclear performance.
Managed Google and Meta campaigns deliver an average 3.8x ROAS across 12M+ euros in tracked ad spend.
Marketing teams spend time on repetitive tasks like email flows and lead scoring instead of strategy.
HubSpot automation, email flows, and CRM integration free teams to focus on high-value strategic work.
Businesses cannot identify which funnel stages are underperforming or leaking revenue.
Full-funnel ownership from awareness to retention enables continuous, data-driven optimization at every stage.
Who we work with best
Ambitious, fast-growing companies looking to scale through data-driven performance marketing. The client base includes e-commerce and DTC brands (evidenced by clients such as GoldRepublic and OrangeFit). Companies typically have existing ad spend but insufficient tracking, attribution issues, or underperforming paid media they want to fix and scale.
