Halo Audio is a Berlin hardware startup launching noise-cancelling earbuds against the biggest names in tech. We built a creator-led performance engine that paid for itself by week three.

The challenge
Halo's earbuds tested better than the category leaders, but their ads looked like everyone else's: renders, spec sheets and discount codes. Cost per acquisition was climbing past what their margins could carry, and the launch window was twelve weeks away.

Our approach
We replaced renders with real moments: the commute, the open-plan office, a toddler's birthday party. Twenty creators produced 140 short ads in four weeks. We tested hooks in batches of ten, cut the losers within 48 hours and scaled the winners across platforms in a weekly creative sprint.
