Our Approach
How we work
Strategy isn't a kickoff deck. It's the ongoing decision-making layer that keeps execution focused, adaptable, and tied to results.
What drives our approach
Business reality, not channel theory
We start with your margins, inventory constraints, cash flow tolerance, and growth goals — not a platform playbook.
Creative as the primary lever
In a world of broad targeting, creative is the strategy. Messaging, format, and iteration speed matter more than micro-optimizations.
Blended performance, not vanity metrics
We optimize against what actually compounds the business: MER, contribution margin, incrementality, and learning velocity.
Continuous recalibration
Strategy is revisited weekly as signals change — creative fatigue, demand shifts, seasonality, and platform behavior all feed back into the plan.
Momentum matters
Performance compounds when teams move with momentum. Momentum is built through tight collaboration, fast feedback loops, and removing friction on both sides. When momentum slows, learning slows — and performance follows.
