How it works
You do not need all three. We start where you are.
Phase 1 · Foundation
First results in about 2 weeks
We make sure your visits, sales and sign-ups are counted correctly and bring your data into one place.
Good if numbers don’t match, or reports are made by hand.
Phase 2 · Marketing or CRM
First insights in about 3–4 weeks
Pick what hurts more. Or do both, one after the other.
Good if your basics work, but you can’t say what pays back.
Phase 3 · Activation
Monthly, cancel anytime
We put your data to work and keep it healthy.
Good if Phase 1 and 2 are in place.
Each step has a fixed scope that we agree with you first. Everything is built in your own accounts, so you keep it. After each step we hand over everything with clear documentation and a walk-through.
Tools we work with: GA4 · Google Tag Manager · BigQuery · Snowflake · dbt · ClickHouse · Looker · Looker Studio · Metabase · Segment · Mixpanel · Python · Google Ads · Meta Conversions API
In-house roles and client projects our team led at these companies.
Marketing spend was not linked to real sales, and reporting was partly manual. We built our own way to link spend to real sales (attribution), sent sales data back to Google Ads and automated the reporting.
~10% lower cost per sale.
Tools: Python · Google Ads · Attribution

Reporting was split between Mixpanel and spreadsheets, and every team had its own numbers. We built one central place for the data, automated the feeds, agreed shared definitions for key numbers and added reports on customer groups, customer value (LTV) and cost per customer (CAC) by channel.
One source of truth for marketing, product and leadership.
Tools: ClickHouse · Python · Metabase · Mixpanel

Tracking had gaps across landing pages, product pages and checkout. We rebuilt it for the whole customer journey, brought all marketing channels into one place and built the reports.
8 hours of manual reporting saved every week.
Tools: GA4 · GTM · BigQuery · Looker Studio

Each market defined its numbers differently, so comparing them meant manual work. We standardised the definitions across all markets and built one central view for leadership.
Compare markets without manual clean-up.
Tools: Snowflake · dbt · Segment · Looker
“Ghiath supported us as an external freelance BI partner, building tailored Looker dashboards for performance channels across multiple EU markets. He proactively improved our data setup, fixed GA4 and tracking issues, and consistently recommended effective solutions. Beyond his technical expertise, he was highly collaborative, empathetic, and easy to work with. I would gladly recommend him to any team looking for a proactive and skilled BI expert.”
Two data experts. One goal: you stop guessing.

Makes sure every visit and sale is counted right, and shows what each channel brings back.
CRM and customer data

Every step has a fixed scope and price, agreed with you before we start. We do not publish prices because the work depends on your setup. The Blueprint gives you a rough idea.
