About

Two decades across five fields.

A Greek technology entrepreneur working across Greece, Europe, the United States, and Asia. For twenty years my work has come back to one practical question: how does a difficult technical problem become a product customers understand, trust, and use?

In cybersecurity I built systems that helped companies detect threats and respond faster. In telecommunications, products for international networks. In fintech, open-banking data and machine learning for credit assessment. In digital assets, tools that measure stablecoin and tokenized-asset risk for financial institutions. The work connects technology, product strategy, business development, regulation, and international growth.

Today I work as an independent advisor and fractional Chief Product Officer. Recent engagements span digital-asset risk scoring, stablecoin analytics and yield strategies, generative-AI platforms, and inclusive credit underwriting.

Selected work

01

Founder & CEO · 2011–14

Companies drowned in network and security data but couldn't tell which events were real threats. Crypteia built AI-powered, self-tuning threat detection that understood each network's vulnerabilities and focused on the risks that actually mattered.

Outcome. Grew to 120+ client installations worldwide; named a top-three European finalist at the EEN Awards in Brussels; acquired by PCCW Global (2014). The work produced granted US patents in network defense and showed that serious security technology can be built outside a major startup hub.

02

VP, R&D & Cybersecurity · 2014–22

A global telecom needed to manage rising network complexity, new security risks, connected devices, and multi-party transactions. I scaled the Crypteia platform into a telecom setting spanning cybersecurity, IoT security, analytics, automation, and blockchain.

Outcome. Scaled the cybersecurity team from 10 to 40 engineers and lifted delivery speed ~30% through an agile transformation across Athens, Hong Kong and the USA. Along the way I developed a patented multi-ledger blockchain platform.

03

Co-founder & CEO · 2018–25

When people move between countries, their financial history doesn't move with them. Finclude used open-banking data and machine learning for cash-flow-based creditworthiness, income, and affordability, reaching the people credit bureaus miss.

Outcome. Raised ~€1M in pre-seed plus €800K+ in grants and prizes, with partnerships including IBM and Mastercard; winner of the NYU Stern New Venture track and Disrupt Greece, culminating in an exit to Cepal Holdings (2025).

04

Sr. Director, Product Innovation · 2022–25

Institutions were interested in stablecoins but had no simple way to measure de-peg risk. The Digital Asset Monitor combines market data, blockchain activity, and machine learning to estimate the 24-hour probability a fiat-backed stablecoin loses its peg.

Outcome. Built Moody's first product-innovation team and launched the Digital Asset Monitor in 2023, tracking 25 fiat-backed stablecoins (~92% of market cap) across five risk pillars. Introduced a GenAI toolchain and a design-thinking approach to product development that compressed time-to-market, enabling the company to launch products 40% faster.

Patents

Five granted US patents.

Across network defense, IoT security, distributed ledgers, and federated machine learning. Full list on Justia →

US 9,319,425

Self-tuning network intrusion detection and prevention

Activates only the security rules that match a network's actual weaknesses, so protection focuses on real threats and adapts as the network changes. Justia →

US 9,392,007

Identifying infected networks from unknown attacks

Normalizes security logs from many tools into one format and cross-references threat intelligence, surfacing compromise even without a single fixed rule. Justia →

US 10,911,494

Security for IoT devices at the network level

Fingerprints connected devices and applies a security profile per device type, protecting cameras, locks, and sensors without per-device software. Justia →

US 12,373,788

Distributed ledger inventory management

Matches resource requests to supply via smart contracts and records usage on a shared ledger, cutting disputes and manual reconciliation between providers. Justia →

US 12,619,920

Distributed adaptive ML for fraud detection

Lets separate units train their own fraud models and share only the learning, so detection improves while raw data stays under local control. Justia →

How I help

Advisory & consulting engagements.

Discuss a project

I work with founders building 0→1 products, private-equity and portfolio companies, enterprise product teams, and boards. Every engagement starts from the problem, whether that means a fractional Chief Product Officer role, an advisory partnership, board and investor counsel, or a hands-on push on a single decision.

Product & innovation strategy

Define new AI, data, and platform products, test whether the market needs them, and build a practical path from concept to launch, including fractional CPO engagements.

Founder & startup advisory

Fintech & digital assets

Open banking, credit data, stablecoins, tokenized assets, and digital-asset risk for institutions, fintechs, and investors.

Executive workshops

Focused sessions that help leadership teams understand a new technology, agree on priorities, and decide what to build next.
