Taja AI case study: Reducing Customer Acquisition Cost on Google & Meta Ads

-60%Customer Acquisition Cost

5x+Return on Ad Spend

-13%Churn Rate Reduction

We achieved a 60% reduction in customer acquisition costs and a return on ad spend over 500%. By scaling video campaigns and optimizing retention, Taja AI went from inconsistent sponsorship-driven growth to a predictable, profitable acquisition engine.

The Challenge

Taja AI had gained early traction through ProductHunt, AppSumo, and sponsored YouTube partnerships, but growth was inconsistent and unpredictable. As a two-person startup, they couldn't afford to keep spending on channels with no reliable return.

The Goal

Build a predictable, profitable acquisition channel that could scale alongside the product, replacing inconsistent sponsorship-driven growth with systematic performance advertising.

Our Strategy

Conversion Tracking

Built end-to-end conversion tracking with server-side events flowing directly to Meta, ensuring accurate attribution even with iOS privacy changes.

Before running a single ad, we built custom conversion tracking from the ground up. We configured server-side events flowing directly to Meta, ensuring accurate attribution even with iOS privacy changes. This gave us the data foundation needed to make every optimization decision with confidence.

Data-Driven Performance Advertising

Launched campaigns that started at ~187% ROAS during the learning phase and scaled to 500%+ through systematic optimization of audiences, creatives, and bidding.

We started with broad-targeting video campaigns on Meta to build initial data. During the learning phase, campaigns returned ~187% ROAS. As the pixel learned and we refined audiences, creative, and bidding strategies, we scaled to a consistent 500%+ ROAS. The key was patience during the learning phase and aggressive scaling once we found winning combinations.

Retention Optimization

Implemented Churnkey to intercept cancellations with targeted retention offers, reducing churn by 13% and amplifying the value of every acquired customer.

We integrated Churnkey to intercept users at the point of cancellation with targeted retention offers. This reduced churn by 13%, which compounded over time, every percentage point of retained users amplified the value of our acquisition spend.
