Overview

About Ali

Ali builds the analysis behind most Ziro Data projects: churn and retention models, subscriber segmentation, Power BI dashboards and campaign measurement.

He spent the last year as an in-house analyst at a video-on-demand streaming platform, where he defined churn rules for each subscription plan, built behaviour segments for the retention team and compared ten SMS campaigns on the purchases they produced rather than the clicks. Before that he worked on marketing data for an investment firm in Dubai, setting up campaign tracking and Google Ads and Analytics reporting.

He started young, joining a training and consulting firm as a business and data intern while still at school, and is now completing a Computer Science degree alongside client work.

On your project

What Ali does, week by week

You'll know exactly who is doing what. This is Ali's part of a typical 4 to 8 week project.

01Week 1

Scoping

Reads your data before the first workshop and lists what it can and can't answer. Drafts the metric definitions for sign-off.

02Weeks 2 to 6

Build

Builds the models and dashboards, and sends the weekly written update: what moved, what's blocked, what he needs from you.

03Final week

Handover

Documents every table and measure, and walks your team through running it without us.

You'll hear from Ali directly when
