Building Young: AI Startup, University Life & Turning Down an Equity Offer | Mert Demirel In this episode of Young Founders Collective, Defne sits down with Mert, a student founder co-building an AI-powered platform, to explore what it really looks like to balance university life and building a company. The conversation quickly moves into something more personal, the weight of making decisions most people don’t face until much later. Mert shares the story behind turning down a $500,000 equity offer, the kind of opportunity many founders chase, and the internal factors that shaped his decision-making. He also reflects on how growing up across international cities influenced his discipline and ambition, and how that global lens continues to shape the way he builds today. Together, they explore how a globally raised generation approaches building differently, and why being young gives you the confidence that if something happens once, it can happen again, giving you more flexibility in the decisions you make. 🎧LISTEN NOW ON: YouTube: https://www.youtube.com/watch?is=fKkDmVWne3AYSsRB&v=R2VWVhqHd6w&feature=youtu.be Spotify: https://open.spotify.com/episode/16qggwb2hrTx9wYLeYMohQ?si=qb_Ffit_QU6ApdPVmNNKqg&nd=1&dlsi=b730f41271444f04 Apple Podcasts: https://podcasts.apple.com/es/podcast/young-founders-collective/id1879274392?i=1000760411681 FOLLOW OUR GUEST: Mert Demirel Linkedin: linkedin.com/in/mert-demirel- Bases Insight Website: https://www.basesinsight.com Nominate a future guest: https://yfcollectivemedia.com
