Restraint over flourish.
Most software is more useful when it asks less of you. We aim for the simplest system that meets the requirement.
About
We build intelligent systems from Lagos.
An AI engineering company started in 2023. We work on quantitative research, ML systems, and software for clients who need real engineering — not just advice.
Who we are
The Elixirs Lab is an AI engineering company founded by Segun John Oni in 2023. We started as a small consultancy helping organizations build data infrastructure that actually worked. Today, we focus on the harder problems — quantitative research, machine learning systems, agent platforms — while continuing to ship reliable software for clients who need to move fast.
We're based in Lagos, Nigeria, registered as The Elixirs Lab Ltd (RC 7206881). Our work spans frontier-market quant research, AI engineering for production systems, and data infrastructure consulting. We collaborate with clients across Africa, the United States, and Europe.

What we believe
Working systems over impressive demos.
Our work has to ship, run, and stay running. Reliability is the feature.
Honest reporting over optimistic estimates.
We tell clients what we know, what we don't, and what's guessing. It produces better outcomes than the alternative.
Long-term over short-term.
We build code and relationships meant to last.
