Dimitrios Ntempos
Technical Product Manager • Integrations, Data & AI
I work on data-heavy B2B products and integrations across gaming, blockchain, travel tech and audience insights. I partner hands-on with engineering as a near-peer on system design, data contracts, SDK integrations, and data pipelines. Outside work, I'm curious about how AI systems behave and the biases in the data they learn from. I explore that through small side projects and sometimes I write.
Currently at GWI, and SpaceXAI Ambassador Regional Leader for Thessaloniki.
What I write
Latest essays on product thinking, startups, and what I'm learning over time.
Structural patterns in product management
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.
Building another GPT wrapper on purpose
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.
