Product Leader
I'm Marios Papasavvas, a product leader with 10+ years in fintech and SaaS — currently interim Head of Product at HFM, leading a 35-person product organization. To show how I work rather than tell, I took a real product from idea to a live, data-heavy application — owning discovery, the backlog, specifications, and every product decision along the way.
Flagship project
A grocery price-comparison app for Cyprus: photograph a receipt or a shelf tag, and know instantly whether you're paying a fair price — powered by AI vision, a curated product catalog, and competitor price data at scale.
Validated the concept with a working AI prototype before committing to a full build — and killed features that didn't earn their place.
Built the product's identity model on barcode evidence over name similarity, instrumented failures before optimising, and cut AI cost per user by half with an A/B-gated change.
Every feature shipped with a written spec or write-up — 47 tickets, each with problem statement, goals, non-goals, and decision rationale. Built to hand over.
Background
Leading a 35-person product department across Product Management, Business Analysis and Product Operations. Grew the product organization from 9 to 35 people in two years (+350%), establishing department, team and role-level KPIs and SLAs for delivery and accountability.
From Product Manager to leading a team of 13 PMs. Launched a loyalty program that drove +351% MoM growth in client deposits and +315% trading volume per enrolled user; scaled a global affiliate network past 80,000 members (+76% registrations, +74% notional volume); shipped trading apps with 1M+ downloads and +47% growth in live accounts within two months.
Delivered Microsoft Dynamics 365 programmes worth €6M+ across Europe and the Middle East (Hellenic Bank, NBK Capital, Louvre Abu Dhabi), leading cross-functional teams of 20+. Before that, delivered the platform that became Cyprus's most popular online food-delivery service in 2015 — an early sign of the consumer-app instincts behind PriceScan.
PMP (Project Management Institute), Professional Scrum Product Owner I (Scrum.org), Microsoft Certified Professional. Project management studies at CIIM (PMI standards); BA, University of Athens. Bilingual: English & Greek — the same two languages PriceScan's matching engine has to bridge.
