What Spike does

Spike is a privately held growth marketing agency headquartered in Amsterdam, Netherlands, founded in 2017 by Gino Taselaar, with Pascal van Steen serving as co-founder and head of growth. The firm targets ambitious, fast-growing mid-market companies and marketplace scale-ups, delivering three integrated service lines: Tracking & Analytics (GA4 implementation, server-side Google Tag Manager, attribution modeling, custom dashboards), Performance Marketing (Google Ads, Meta Ads, paid search and social, funnel optimization), and Marketing Automation (HubSpot-based email flows, lead scoring, CRM integration). Its technology approach centers on measurement infrastructure and attribution rather than proprietary software, and the service stack is positioned as a full-funnel system spanning awareness through revenue.

The business operates on a managed-services model, generating revenue through retainer- or project-based engagements sold via a sales-led, consultative GTM motion anchored on the company website (wespikegrowth.io) and supported by named client testimonials. Spike does not disclose pricing, has no disclosed institutional funding, and lists no channel partners, patents, awards, or regulatory actions. Reported operational metrics include 80+ clients served, €12M+ in tracked client ad spend (an output metric, not Spike's own revenue), an average client ROAS of 3.8x, and a 95% client retention rate.

Structurally, Spike is a founder-owned boutique agency with limited disclosed headcount, no parent company or subsidiaries, and no public market listing. Its competitive positioning rests on leading with measurement infrastructure before campaign execution, with documented client outcomes (e.g., a 2.4x ROAS improvement at GoldRepublic within three months) serving as the primary trust mechanism. Distribution is positioned as 'global' despite Amsterdam-only operations, indicating intent to serve cross-border clients, though no concrete international footprint, hiring data, or growth-rate disclosures are available to substantiate scale.
