In this episode of The Tech Series, host Marcelo De Santis sits down with Erich Kerekes, Co-Founder & CTO of Hallow, the world’s most popular Christian prayer and meditation app with over 20 million downloads. Filmed inside the historic Holy Name Cathedral in Chicago, this conversation explores the powerful intersection of faith and technology. Erich shares the origin story of Hallow, how the app helps millions deepen their prayer life, and what it means to bring spirituality into the digital age. We also hear from Father Ton Nguyen, who explains how his parish uses Hallow to build community and bring people back to church.
