Rafael Papagiannis

Head of Product @ Starttech Ventures

Speaker's Bio

I’m Head of Product at Starttech Ventures in Athens, where I manage product strategy across our portfolio of early-stage companies including EndoGusto, an endurance training platform, and Gracely, a church management SaaS. I work directly with founding teams to drive activation, retention, and monetization while building product operations from scratch.

Previously, I spent over three years at Skroutz, Greece’s leading online marketplace. As Senior Product Manager for Advertising, I reversed two consecutive quarters of decline in Sponsored Products, achieving an all-time high ad take rate of 0.46% and driving a 24% YoY increase in marketplace ads revenue. Earlier, I led Seller Growth and New Verticals, growing quarterly deals GMV by 430% YoY and improving 14-day retention by 10 percentage points for our Groceries product.

Before Skroutz, I was Product Manager at FoodTec Solutions, where I shipped features that decreased weekly forgotten delivery items by 75% and tripled our at-the-door payment solution’s user base in one quarter.
