How We Cut Our Client's CAC by 43% in 90 Days

The Challenge

Our client was spending £15,000/month on paid social with a customer acquisition cost (CAC) of £120 — far above their target of £70.

What We Did

We introduced three AI-powered changes to their workflow.

1. AI Creative Generation at Scale

Using a combination of tools, we generated 40+ ad variations in 48 hours instead of 2 weeks. More creative volume means faster learning cycles and cheaper winners.

2. Predictive Audience Segmentation

We used AI to analyse their existing customer base and identify micro-segments most likely to convert — reducing wasted impressions by over 30%.

3. Automated Bid Optimisation

We set up automated rules tied to real-time performance signals, ensuring budget shifted toward what was working within hours, not days.

The Results

• CAC dropped from £120 to £69 in 90 days
• ROAS improved from 2.1× to 4.8×
• Creative production time reduced by 70%
