Efectivum is a small, senior ecommerce growth team led by Ardi Kristovald. We plug into your stack, find where profit is actually leaking, and rebuild the systems that drive margin, retention and conversion.
Most DTC brands don't have a traffic problem — they have a clarity problem. Ad platforms report one number, Shopify another, the P&L a third. Meanwhile CAC creeps up, retention plateaus, and nobody can point to the real profit drivers.
We started Efectivum to fix that gap: give founders one honest view of their numbers, and the engineering muscle to act on it. After 20+ years building ecommerce, analytics and automation systems for brands across the EU, that is still the only thing we care about.
Years in Ecommerce
Four principles that show up in every engagement — from the first audit call to the last playbook we hand over.
We optimise for contribution margin and LTV, not surface-level revenue or traffic charts.
Every engagement ships working dashboards, automations, and playbooks — not decks that sit in Drive.
Strategy, analytics, CRO, automation and development under one roof, so nothing gets lost between teams.
If a channel or tactic is not going to move profit, we tell you before you spend on it.
