Overview

Not academic expertise.
Operational experience.

Technology law is the practice area where Pantazis & Associates is most distinctively positioned. Dionysios Pantazis has served for eleven years as general counsel to a Fortune 50 technology group, overseeing legal strategy across seven business lines and eight countries. A technology lawyer in Athens who has sat in-house tends to give shorter answers, because the commercial question is already understood.

His experience spans public procurement law and tender exclusions, national security designations, EU competition law, GDPR compliance, large-scale IT contracts, software licensing, multi-jurisdictional regulatory strategy and commercial dispute resolution — built inside one of the most legally complex technology businesses in the world, at a scale very few lawyers in Greece have encountered.

"We understand how technology companies actually work: how contracts are negotiated under commercial pressure, how regulators behave in practice, and how legal strategy must adapt to the pace of technological change." Foreign technology companies use a technology lawyer in Athens to translate EU obligations into what their Greek entity must actually do.

We advise AI corporations, telecoms operators, cloud service providers, digital platforms, SaaS companies, digital energy businesses, technology startups and the investors who back them — on the full range of their legal needs in Greece and the wider European region. Describe the product and we will identify the regulatory exposure.

Our technology practice is organised across seven sub-practices, each with dedicated expertise. Whether you need an EU AI Act compliance programme, a complex SaaS agreement, a GDPR investigation, a startup investment round or a platform antitrust matter — we have the specialist knowledge to advise you precisely and efficiently.

Why it matters

In-house experience changes everything

External lawyers advise on the law. In-house lawyers live inside the commercial reality. Dionysios has been both — and brings the judgment of both to every technology matter we advise on.

Regulatory depth

EU AI Act · GDPR · NIS2 · DMA · DSA

We advise on the full stack of EU digital regulation — from AI governance frameworks and data protection to platform rules and cybersecurity requirements. Implemented, not just interpreted.

Cross-border reach

Greece, Europe and beyond

Most of our technology clients operate across borders. We coordinate with foreign counsel, advise on multi-jurisdictional contracts, and handle cross-border regulatory strategy as standard.

Speed

Technology moves fast. So do we.

We understand that in technology, the cost of legal delay is real. We work at the pace our clients need — without compromising on quality or precision.

Accreditation

A decade inside a
Fortune Global 50
technology company.

Dionysios Pantazis has served for eleven years as general counsel to a Fortune 50 technology group, managing legal operations across Greece, Bulgaria, Romania, Serbia, Croatia, Slovenia, North Macedonia and Cyprus. He handled public procurement challenges and national security designation proceedings at the highest political and regulatory level, managed competition investigations, and negotiated commercial agreements with governments, telecoms operators and enterprise clients.

Pantazis & Associates is recommended by a number of foreign embassies operating in Greece, including the UK, US and Australian embassies. The firm's lawyers are frequently invited to speak at international legal conferences and symposia, and the firm regularly provides opinions, analysis and commentary to international institutions such as the World Justice Project and the World Bank. In technology law, as across the firm's practice, we have advised on matters that other lawyers read about in textbooks and legal journals — institutional recognition that no marketing budget can buy.
