Ἀρχὴ ἥμισυ παντός
Be a Mentor!
At Techstars Startup Weekend Thessaloniki, mentors play a decisive role in shaping the experience. In just 54 hours, teams need expert guidance to validate their ideas, explore their market, and turn concepts into actionable plans.
As a mentor, you bring your expertise, perspective, and critical questions that push participants beyond assumptions. Your insights can be the turning point between an idea that stays on paper and one that evolves into a real venture.
Beyond supporting teams, mentorship is equally rewarding for you: it’s a chance to connect with fellow professionals, expand your network within the startup ecosystem, and inspire the next generation of entrepreneurs.
