Structural patterns in product management

Thu, 19 Feb 2026 00:00:00 GMT

Different industries. Same structural questions. Whether a feature gets approved, a funnel declines, or delivery slips, the surface changes but the underlying tensions remain. This is the operating logic I rely on when clarity competes with speed. Not a framework. Just a snapshot of how I think. Take what is useful.

The Case Background

Recently, I worked with a travel tech company. The platform allows property owners to list and distribute their properties to short-term rental marketplaces. The domain is irrelevant. What matters is this: I’ve seen the same structural patterns in completely different environments. Approvals without clarity. Assumptions without data. Solutions discussed before constraints are understood. Different industries. Same questions.

Building another GPT wrapper on purpose

Thu, 29 Jan 2026 00:00:00 GMT

AI is everywhere and building with it has never been easier. Models are powerful, accessible, and here to stay. So if intelligence is becoming a commodity, what actually differentiates a product? This post is about building Easyscout, another “GPT wrapper”, and why focusing on real problems, UX, and orchestration matters more than the model itself.

When AI fades into the background

Discussions about AI products often revolve around the model; which one is used, how smart it sounds, how close it feels to reasoning. That framing made sense when access to intelligence was scarce. It doesn't hold anymore. Large Language Models are widely available, improving fast, and accessible to almost everyone. When intelligence becomes a commodity, it stops being a sustainable unique selling proposition.

Short reflection on 2022: leaving Wappier after three years, taking a six-month break filled with family time and side projects, and starting a new chapter at 100 Mentors.

Bye bye wappier

Product versus project the narrative

Thu, 22 Dec 2022 00:00:00 GMT

Τech companies, they build products or projects. They both might bring in fuel to get them going; however, apart from making money, what’s the vision? That's usually a good question to ask when trying to differentiate product and project 🧬DNA companies.

Introduction

They called me a project manager more than twice. I wasn’t shocked. The other day, a colleague sent me a message “I am doing a master’s! Next week I am going to learn your stuff, project management” damn! Also, the teacher of a technical course for product managers I am doing brought up the subject once again. Olah lah! Today I am sure there is a clear need to prioritize this writing idea, and define the main differences between products and projects.

Technical literacy for Product Managers

Fri, 24 Jun 2022 00:00:00 GMT

Product Manager, a role right in the intersection of business and tech that needs both technical and business skills to get things going. But, does it really need technical skills? Some! You don't need to be an engineer but... 🤿 let's dive deep.

Introduction

As product management matures you might have noticed the different types of Product Manager roles popping up often. According to a quick search I’ve just performed, there is currently a wide spectrum of Product Manager roles such as Data Product Manager, UX Product Manager, Growth Product Manager, Technical Product Manager, AI Product Manager, Enterprise Product Manager, and the list goes on but this is out of context for now so let’s stop here.

Serving on the SXSW Accelerator Advisory Board

Sun, 18 Nov 2018 00:00:00 GMT

Reflections on serving on the SXSW Accelerator Advisory Board, reviewing early-stage startups from around the world and helping founders from Greece and Cyprus participate in one of the most well-known startup events.

The Role

Tech events have always been environments I enjoy. They bring together people building new things, such as founders, engineers, investors, and curious observers, all exchanging ideas about what technology might look like next. In Autumn 2017, I joined the Advisory Board for the 2018 [SXSW Accelerator](https://sxsw.com/pitch/). This program is a startup pitch competition held annually during the SXSW Conference in Austin, Texas.

Does your brilliant billion dollar idea compile into a sustainable business? Do you really need this funding now? We are in 2049 and you are building a Spacecraft 🚀. How a minimum viable business plan might look like?

Summary

Thessaloniki is the place to build your startup

Tue, 12 May 2015 00:00:00 GMT

Dear doers, makers, and shakers. Welcome to Thessaloniki’s Startup City Guide. You might be aware of our beloved city for the party vibe and the beautiful beaches of the nearby Chalkidiki. Ok, rewind this for a moment; we do also have a super active and fast moving tech community here.

Heading To Thessaloniki

Thessaloniki is the biggest European city before Asia, it lays on the coastline of Thermaikos gulf and inhabits around 1 million people. The city is founded in 315 B.C. and named after the sister of Alexander the Great. Throughout the centuries it has been home for many cultures including Greeks, Turks, Jews and Romans. Any of them left a twist so that you can hardly not feel at home.

Recommender Systems for Location-Based Social Networks

Sat, 08 Feb 2014 00:00:00 GMT

This post is based on my master’s thesis contribution to the Springer book Recommender Systems for Location-based Social Networks. It explores how recommendation algorithms adapt when social networks incorporate geo-location data, and how such systems can power friend, activity, and place recommendations.

Introduction

Online social networks collect information from users' social contacts and their daily interactions (co-tagging of photos, co-rating of products etc.) to provide them with recommendations of new products or friends. Lately, technological progressions in mobile devices (i.e. smart phones) enabled the incorporation of geo-location data in the traditional web-based online social networks, bringing the new era of Social and Mobile Web. The goal of this book is to bring together important research in a new family of recommender systems aimed at serving Location-based Social Networks (LBSNs). The chapters introduce a wide variety of recent approaches, from the most basic to the state-of-the-art, for providing recommendations in LBSNs.

Taking an early-stage startup to Web Summit

Thu, 12 Dec 2013 00:00:00 GMT

A reflection on taking an early-stage hardware startup to Web Summit in 2013 — preparing a portable prototype, presenting to an international audience, and learning how large conferences actually work for early-stage teams.

Context

In 2013 our team was building [Sociallgreen](https://sociallgreen.com/), an early-stage hardware startup focused on recycling technology. At the time we were participating in one of the first entrepreneurship incubation initiatives in Greece and working on a prototype of our system. That summer I came across a conference I had never heard of before: Web Summit. The idea of presenting our startup outside Greece seemed ambitious for such an early-stage team, but we decided to apply anyway. To our surprise, we were accepted to exhibit in the Alpha startup program.

What an early tech startup incubator taught me

Sun, 04 Aug 2013 00:00:00 GMT

A reflection on participating in one of the early startup incubation programs in Greece in 2013 — what it taught me about feedback, hardware development, and the realities of early-stage ecosystems.

Context

It’s 2013 and the startup ecosystem in Greece is still forming. New initiatives are emerging from both public and private organizations with the goal of helping young founders develop entrepreneurial skills and turn ideas into companies. At the time, my team was building an early-stage hardware startup called Sociallgreen. During the pilot phase of one of the first government-backed incubation initiatives, four members of our team participated in the program from February to June 2013. During those four months we delivered the first prototype of our product and incorporated the company under Sociallgreen P.C. It was an intense period that taught us a lot about both product development and the realities of early startup ecosystems.
