Who We Are

PENTARKON is the specialized European consultancy built to bridge the divide between traditional banking integrity and the fast-moving world of FinTech and Crypto-Assets. We empower financial institutions, payment firms, and digital asset companies to conquer complex regulatory frameworks — including MiCA, DORA, and AMLD6 — without sacrificing speed or innovation. Our team brings hands-on experience from institutions like American Express, National Bank of Greece, and Ebury, deployed with the agility of a focused specialist firm. We operate across Southern Europe and globally, with deep alignment to the regulatory expectations of SEPBLAC and the Bank of Greece — and native fluency in Greek, Spanish, and English.

Our Mission

To transform compliance from a cost center into a growth enabler — through technology-first innovation and institutional-grade execution.

Our Vision

Compliance is no longer a checklist. It is an active defense system.

The 5-Pillar Methodology

Everything we do is structured around a proven five-pillar framework that covers the full compliance lifecycle — from boardroom strategy to real-time automation.

I. Strategic Governance & Design

Architecting resilience, not just following rules. Regulatory roadmapping, board advisory, and institutional-grade policy architecture for MiCA, DORA, and GDPR.

II. Operational AML & Investigations

The technical heart of financial crime prevention. Transaction surveillance via Siron, RiskShield, and Napier. Certified Chainalysis blockchain forensics. High-integrity SAR/STR intelligence.

III. Managed KYC & Client Lifecycle

Frictionless onboarding, uncompromised compliance. Digital integration, KYC remediation strike teams, and forensic enhanced due diligence for PEPs and complex structures.

IV. Independent Quality Assurance

The "Audit of the Audit" — your final line of defense. Level 3 QA reviews, systemic risk detection, and regulatory liaison during formal audits.

V. RegTech & Automation (PENTARKON Platform)

Scaling compliance through data intelligence. PENTARKON AI (investigation automation), PENTARKON Automations (real-time GRC monitoring), and PENTARKON Sandbox (synthetic stress testing environments).
