Zello

We started as a company that turned phones into walkie-talkies. Today, we modernize instant voice communication with our industry-leading push-to-talk technology to help mobile workers meet quickly changing, urgent, real-world challenges.

We have the highest-rated walkie-talkie app, with over 8 billion messages sent per month and 170 million users in industries such as transportation, retail, construction, hospitality, healthcare, and more.

We’re proud to serve frontline workers, we’re privileged to connect people in times of crisis across the globe, and we’re honored to support first responders. As demand for our app continues to rise, we’ve evolved from a startup to a scale-up — and we’re still growing rapidly, which is where you come in.
