About us · Reactit

A small firm
of engineers.

Founded in 2020. Based in Sousse, Tunisia. Twenty-four people building, running and augmenting the software inside a generation of MENA financial institutions.

01 · The story

Reactit was founded to be
the calmest line on the page.

An honest account of how Reactit came to be and what it is for.

We were certain of one thing — the region's next core systems should be built, not bought.

Reactit was founded in 2020, in Sousse, by a small group of engineers who had spent a decade inside the IT departments of MENA insurers and banks. We began with one engagement — a templates service for a life insurer — shipped, instrumented and supported from inside the client's own operations. It is still in production today.

The principle behind it still holds: the team that designs the system is the team that runs it. Today we are twenty-four people across three pillars — Build, Run, Augment — selective about the work we take. We'd rather ship one durable thing than five exciting prototypes, and we measure success in the on-call hours our clients never have to spend.

02 · Principles

Four principles,
written down.

The operating principles we put on the wall when we founded Reactit. Still on the wall.

01 / 04

Production first

or it doesn't exist

We don't ship demos, prototypes, or slide decks. Every engagement is graded on whether the system is running, observable, and supportable on the day we hand it over.

02 / 04

Engineers, not consultants

on every engagement

The people who design the system are the people who write the code, debug it on a Wednesday night, and answer the page at 03:00. We do not separate the strategist from the builder.

03 / 04

Boring software,

durable outcomes

We prefer the unfashionable choice when it lasts longer. Most of our work is to make institutions calmer, quieter, and harder to break — not louder, faster, or more impressive in a demo.

04 / 04

Open by default

with our clients

We work in shared repositories, write postmortems our clients can read, and transfer ownership in the open. The brief is the handover, from day one.

03 · The firm, in numbers

Where we are
at the moment of writing.

We will update these numbers when they change. We will not invent them.
