// what I do

Three things. One system.

Everything I build points in the same direction: a retention discipline that treats every retained customer as a compounding revenue asset - not a renewal checkbox.

// the book

Retention Schematics:
The Revenue Compounding
Playbook

Most retention books were written for US and European SaaS companies - built on benchmarks, culture, and sales dynamics that don't hold in MENA. This one was built here. It introduces Retention Architecture as a discipline: the practice of designing systems that compound NRR, not just defend against churn.

33 chapters - 29 structured for scaling companies, 4 purpose-built for early-stage startups
The RARE Framework - Revenue Architecture and Retention Excellence: the operating methodology for NRR compounding
MENA-calibrated - built on operator-scale experience at STC and Mobily across Saudi Arabia, UAE, and Egypt
Not tactics - systems: tactics tell you what to do once; systems tell you how to build something that works at any account, any team size
Companion toolkit included - the Retention Schematics OS is the operational layer that runs the book's framework

The Retention Revenue Architect
Revenue systems architect specializing in B2B SaaS retention for MENA markets. 20+ years managing retention at operator scale - STC and Mobily - across 40M+ subscribers with full P&L responsibility. Author of Retention Schematics. Based in Cairo.

// about the architect

Built from operator-scale retention - not consulting theory.

Every tool in the Retention Schematics OS and every chapter in the book came from a real problem encountered running retention at scale - first in telecom, now in SaaS and fintech consulting. The CAC Calculator exists because companies were presenting a board number missing 40% of the real cost. The Onboarding Tracker exists because enterprise accounts were going silent in Month 2 and nobody noticed until the renewal conversation 10 months later. The RARE Framework exists because "reducing churn" was never the right goal - expanding every customer's value over time is the system. Retention Schematics is how you install it.
