Erich Kerekes ’15

Chief Technology Officer and Co-Founder, Hallow

Major: Computer Science

Providing spiritual support to millions

Erich Kerekes ’15 is the CTO and co-founder of Hallow, a Catholic app offering resources on prayer, meditation, music, the Bible, and sleep. He coded the application and currently leads all of the product, tech, design, and analytics for the company. The app crossed 20 million downloads in 2024 and is the No. 1 Catholic app in the world.

Kerekes admits that his Catholic devotion was lacking before enrolling at Notre Dame, and it was not until his co-founder, 2019 Domer Dozen honoree Alex Jones ’15, approached him about Hallow that his faith journey was transformed as he embraced the contemplative and meditative aspects of Catholicism.

In five years, the Hallow team has raised more than $105 million in venture funding and the company has swelled to 80 employees.

Kerekes graduated summa cum laude from Notre Dame with a degree in computer science in 2015. In 2022, he and his co-founders, Jones and Alessandro DiSanto ’15, were named to the Forbes 30 Under 30 list, recognizing their impact and innovation in the tech and faith space.
