What we do
Six ways we plug into your technology
From regulatory licensing programmes to hands-on platform delivery, we take on the work that needs a senior pair of hands.
CTO & Technology Leadership
Interim and fractional CTO support for teams that need senior ownership of strategy, architecture, and delivery.
Payments & Regulated Platforms
Building payment and fintech platforms that pass regulatory scrutiny — from PSD2 licensing to KYC/AML readiness.
Architecture & Platform Engineering
API-first, event-driven architectures for high-transaction, integration-heavy systems built to scale and survive.
Cloud & Production Operations
Cloud foundations and operational discipline that keep high-traffic systems fast, observable, and affordable.
Data, Personalization & Search
Real-time data platforms that turn customer behaviour into personalization, search relevance, and better decisions.
Applied AI & Automation
Production-grade LLM and agentic systems applied where they create measurable value — not where they look impressive.
About us
Fifteen years of building systems under real pressure
Maria Bennis AB is an independent consultancy rooted in fifteen-plus years of senior engineering and CTO work across payments, grocery retail, e-commerce and marketplaces — in Sweden, the Gulf and across Africa.
That means licensed payment platforms built to withstand regulatory review, real-time commerce platforms serving millions of users, and engineering organisations grown from a handful of people to forty.
We work as an extension of your team — pragmatic, transparent, and accountable for the result rather than the hours.
More about how we workSectors we know well
“Most organisations don't need more technology. They need the right technology, explained clearly and delivered well.”
The principle the firm was founded on.
How we work
A short path from question to result
Understand
A short, focused discovery of your architecture, delivery reality, and commercial constraints — no lengthy audits.
Decide
A clear target architecture and prioritized roadmap, sized to your team, budget, and regulatory obligations.
Deliver
Hands-on execution alongside your engineers: architecture, delivery governance, and production readiness.
Hand over
Documentation, enablement, and knowledge transfer so the team owns the platform long after we step out.
Hands-on seniority
The person advising you is the person in the architecture, the code review, and the incident channel.
Built for scrutiny
Security, auditability, and compliance are designed in from day one — not retrofitted before a regulator calls.
Outcome over output
Every recommendation is measured by the business result it creates, not by the size of the project it justifies.
