Where they were when we started.
Meridian was running a $15K/month paid program with a healthy 8× ROAS — and a board mandate to grow 10× without losing efficiency. Two previous agencies had tried and failed; spend would scale, ROAS would collapse. Their attribution was Google Analytics last-click, which lied about what was working.
How we shipped it.
- 01
Replaced last-click attribution with a multi-touch model fed by server-side tracking, validated against a 90-day holdout test.
- 02
Built a structured creative-testing framework — 8 variants per concept per week, each tagged for retention, retargeting, or prospecting.
- 03
Layered AI-powered bid optimization across Meta, Google, and LinkedIn that respected the new attribution signals rather than the platform-native ROAS.
- 04
Ran systematic landing-page A/B tests on the top-of-funnel — typically the bottleneck once paid spend scales past $50K/month.
What changed for the business.
- $15K → $150K/month spend with sustained 9.2× ROAS — actually higher than the starting baseline.
- +340% revenue growth attributable to paid acquisition over the engagement.
- 45% reduction in CAC, primarily from the creative-testing program weeding out underperformers earlier.
- In-house team picked up the playbook on month 9 and now runs the program with us as advisor.
“Scaling spend from $15K to $150K monthly while improving ROAS seemed impossible. Big Bold made it look routine — and the analytics they built means we actually understand why it's working.”
