Home energy company selling residential solar panels and home batteries direct to homeowners across the Benelux.

The challenge

The client was buying nearly all of its leads from third-party brokers, resulting in shared, cold, and late contacts with conversion rates as low as 0.8–5%. There was zero tracking from click to CRM, making attribution impossible and budget decisions purely guesswork. The rented pipeline taught them nothing—no audiences, no creative learnings, and every month starting from zero.

Our approach

• Stretch began with a full growth audit producing 50 scored ideas, narrowed to 21 prioritised experiments, with end-to-end tracking implemented before any ads ran. Experiments launched simultaneously across major ad platforms and a dormant email database, with kill-or-scale verdicts made within days. Winners—including a savings calculator, educational e-book, database reactivation, and policy-moment hooks—were duplicated into new regions using pre-validated campaigns only, cutting losses paid in region one from ever repeating.

The result

Within 8 months, lead-to-sales-qualified rate improved from roughly 1-in-3 to 3-in-4, cost per sale dropped ~80%, and revenue quadrupled—all on the same budget. The second region launched at approximately 50% lower cost per lead by inheriting only validated winners. The client now owns a fully attributed, compounding lead engine with zero dependency on brokers.
