The Challenge

Paid spend was spread across multiple platforms with manual bid changes and guesswork on creative. Customer acquisition cost crept up every quarter and reporting lagged days behind decisions.

The Solution

We built an AI-assisted optimization loop that syncs spend, conversions, and revenue into one model, then recommends budget shifts and bid adjustments daily. Automated creative testing surfaced winning variants faster, and a unified dashboard connected ad spend to actual revenue.

The Results

  • 26% reduction in blended CAC over one quarter
  • 1.8x increase in winning creative throughput
  • ROAS improved from 2.4x to 3.3x
  • Daily, revenue-aware budget reallocation

“We finally make budget decisions on daily revenue signals instead of last week's gut feel.”

What we did

Lumen Commerce ran healthy volume but managed bids by hand and judged creative on intuition. We unified spend, conversion, and revenue data into a single model and let it recommend daily budget and bid moves.

Automated creative testing meant more ideas in market and faster reads on what worked. Tying everything back to actual revenue, not just clicks, kept the optimization honest.

The combination drove acquisition cost down while pushing return on ad spend up.
