— DeepTech AI Engineering · Sovereign AI · Malta EU

Built To Last.

Most organisations know they need AI. Few know where it fits, whether their data is ready, or how to run it without handing control to someone else's infrastructure. We answer all three. And then we build it. Sovereign. Compliant. On your terms.

// Our Approach

Sovereign AI.
Compliant By Design.

Sovereignty and compliance aren't checkboxes we tick before shipping. They're the reason we started this company. Because when AI goes wrong, and without the right foundations it does, someone has to answer for it. With RetroGradient Labs, the answer is always clear, always yours.

01

We Meet You
Where You Are

Don't know where AI fits? We find it. Data not ready? We fix it. Ready to deploy? We build it. Already running AI and worried about what comes next? We move you somewhere safer.

02

You Always Know
Where Your Data Is

Your data never leaves the EU. No GDPR grey areas, no exposure to foreign data laws, no wondering which vendor has a copy of your contracts. What we build stays inside EU law. Always.

03

You Never Dread
the Next Audit

GDPR and EU AI Act compliance built in from day one, not added at the end. Audit trails, access controls, human review on critical outputs. Your legal team can sign off with confidence.

04

You Get Engineers,
Not Consultants

We've shipped production AI in factories, classrooms, trading systems, and edge devices. We stay until it works. And make sure it keeps working.

// What We Offer

Your Intelligence,
Made Intelligent.

Three ways in. One standard of engineering across all of them.

The rules changed. Most AI hasn't.
Yours should.
GDPR
Fines of up to 4% of global annual turnover for data protection failures
EU AI Act
Mandatory risk classification, documentation, and human oversight for high-risk AI systems
Reputational risk
A single breach or non-compliance finding can cost more than the technology ever saved
Built for this
Every system we ship is designed to hold up under regulatory scrutiny from day one
// Founders

Currently in active engagement with Maltese government and private sector organisations.

Built by
Engineers First.

RetroGradient Labs was founded by two engineers who have spent nearly a decade building production AI for businesses that needed it to actually work. We started this company because the gap between AI promises and AI products keeps widening, and the only way to close it is to build properly from the ground up.

Natalia is a Maltese AI engineer with eight years of experience building AI that actually ships, in factories, classrooms, and creative studios. She holds an MSc in Artificial Intelligence from the University of Malta, speaks at NVIDIA's flagship developer conference, and was recognised across three categories at Malta's Best Businesswoman Awards 2025. At RetroGradient Labs she leads strategy, client relationships, and product, with one rule: AI is only useful if it's trustworthy enough to put into production.

Leveraging NVIDIA data-center GPUs for AI inferencing

Benchmarking the NVIDIA A2, A10, A40, A100, L4, L40, and H100 across a real production video-inference pipeline (PeopleNet, FaceDetect, face-mask classification). Practical findings on tracker choice, interval values, and where decoders become the true bottleneck.

Natalia on responsible AI, LLM realities, and what production looks like

Strategic takes on where AI hype meets engineering reality: LLM limitations, the gap between trustworthy AI and AI marketing, responsible deployment in regulated sectors, and what enterprises actually need before adopting generative systems.

Explainable multi-layer COSFIRE filters robust to corruptions and boundary attack, with application to retina and palmprint biometrics

A learning-free, hierarchical computer-vision approach to biometric identification on retina and palmprint images. Achieves perfect classification on the VARIA and RIDB retina datasets and 97.54% accuracy on the IITD palmprint dataset, while remaining robust to decision-based black-box adversarial attacks and to partial matching at 80% image visibility.
