The people behind Sponge

Meet the team

Three co-founders. One shared conviction. We’re building Sponge because we believe hydration should be automatic — and we’re doing it ourselves, from the ground up.

Nathan Katzaroff

Co-founder & CEO

Nathan leads strategy, sales, marketing, and operations. He runs the website, manages social media, sets up partnerships, and handles the financial and business side of Sponge. If it needs doing and nobody else is doing it, Nathan is doing it.

Christopher Miglio

Co-founder & CTO

Christopher built the Sponge app and leads all product development — hardware prototyping, firmware, and software. He is the reason the device works. Every technical decision from the clip to the app runs through him.

Dominic Dal Porto

Co-founder & CIO

Dominic built and manages Sponge’s data infrastructure — user data encryption, AWS databases, and backend order processing. He keeps the systems running securely and reliably behind everything customers interact with.
