About

Togethrust, and how I got here

I'm a fractional CTO based in Paris, working with fintech and software companies across Europe: 18+ years of engineering across 5 countries, a regulated banking background in trading systems and core banking, and clients including BNP Paribas, Société Générale, Crédit Agricole, Desjardins and EDF.

I'm CTO and one of three co-founders of Togethrust in Paris, a French-regulated fintech (IFP/ORIAS, ACPR-supervised). We digitize tontines (savings circles) for Francophone African diaspora communities. Togethrust has been through the HEC Paris Incubator, Station F, Founder Institute and Blue Factory, ESCP's incubator. That is my full-time work.

Alongside it I run a small fractional CTO practice: a 15-hour, fixed-scope tech audit for pre-seed to Series A founders, one per quarter. Deliberately small, and designed to stay that way.

I grew up in Kébili, in Tunisia's Saharan south. My first computer came in 1992, at 7: an Amstrad, 8MHz, no hard drive, two 3.5" floppy drives. In 1996 Tunisia placed one internet-connected computer per region, and I spent my allowance buying time on Kébili's. When the CNIPE, the national children's computing center, opened there, I was one of the first kids in.

I represented Kébili at every national kids' competition and won other olympiads later. In 1999, at 14, I competed on Tunisia's first national TV channel, on a show called The World of the Internet: Kébili against Tozeur, a speed-navigation team event, then a live 1-vs-1 website-building duel. FrontPage era, before anyone had heard of Google. I beat an 18-year-old. The prize was my first trip to France.

I came home, became an engineer (ENICarthage, 2007), and moved to France in 2010, to the country that first trip had shown me. Since then: 18+ years on banking systems at BNP Paribas, Société Générale, Crédit Agricole and Desjardins, across France, Switzerland, Canada, the UAE and Tunisia. I co-founded SOCRATES Canada, and co-organized Software Crafters Montréal and Romandie Software Crafters. I build for communities like the one I come from.
