We created Phonein as a solution for those who have missed deliveries, had to cross the city to hand out keys for Airbnb guests, or had to manage keys and access cards for colleagues.

Our goal is to give back time to our users with a smart and safe solution.

Phonein Go is the first available member of Phonein’s smart home product lineup. It is compatible with hundreds of types of intercoms all around the world.

It gives you your freedom back!

Jesse Eisenberg, CEO

As an American living abroad, I saw the incredible beauty in the classic architecture of Europe, however the smart systems were missing. I loved to travel here, and hosting guests and getting deliveries are part of the fun modern life.

So Jesse and the team organized around the idea of a universally-compatible smart door intercom, to smarten-up the beautiful classic buildings all around the world. Let’s make our spaces smarter, and safer and in harmony with our lives.

Made with love in Budapest ❤️
