What the engine delivered
The challenge
A Benelux residential solar and home-battery installer relied almost entirely on third-party lead brokers for pipeline. Bought leads were shared, cold, and converted at under 5%. There was zero click-to-CRM attribution, no creative learnings, and no compounding — every month started from zero. Turning off broker invoices would have stopped the pipeline the same day.
Our approach
- A full growth audit produced 50 scored ideas, narrowed to 21 experiments, with full tracking from click to CRM installed first. Experiments ran in parallel across ad platforms and a dormant email database, each receiving a kill-or-scale verdict within days. Winners — including a savings calculator, an educational guide, database reactivation, and policy-moment hooks — were duplicated into new regions with localised messaging, while losers were documented and never repeated. Cold leads entered a 5-step nurture flow rather than a graveyard.
The result
The client generated 21,068 owned leads at €22 each over 16 weeks, growing from 1 lead in week one to thousands per week by month five. Lead-to-sales-qualified rate rose from roughly 1-in-3 to 3-in-4, cost per sale fell ~80% within 8 weeks, and revenue grew 4x in 8 months — all on the same budget, now fully attributed and owned.
Every lead they had was someone else's data. They were paying for names their competitors could also buy, with no visibility into why deals closed or why they died.
