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

-56%Customer Acquisition Cost

5x+Return on Ad Spend

-13%Churn Rate Reduction

We achieved a 56% 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.
