Product description

Product Description

Leeo Smart Alert is the smart, plug-in safety device that lets you know via smartphone if your home’s smoke or carbon monoxide (CO) alarms go off while you’re away. You can listen, dismiss, or notify local 911 from wherever you are. What’s more, there are no monthly fees and it works with the smoke and CO alarms you already have, giving you connected home security without the cost. With over 16 million soothing colors, peace of mind has never looked better.

From the Manufacturer

Added security when seconds count

In a fire or CO leak, acting fast can make all the difference. Leeo listens for alarms and notifies you the moment it hears one, so you can take action from wherever you are. You can listen to the alarm, dismiss the notification, or contact local 911 — all right from the app.

No installation. No monthly fees.

Because Leeo works with the alarms you already have, there’s no complicated setup. And with no monthly fees, Leeo makes peace of mind very affordable. Just plug it in, connect to your home’s WiFi, and you’re good to go.


Two-minute setup

Leeo works with your existing, up-to-code smoke and CO alarms. Just plug it in and connect to your home’s WiFi for the easiest installation ever.


One per home

Because Leeo listens for the frequency of your existing smoke/CO alarms, you only need one — and not 7 or 8 — for a typical home.


Calls for help

Leeo knows your home’s local emergency number and calls friends and family members you choose if you’re away from your phone.


Leeo blends seamlessly into any home, while the ambient light setting turns on a soft light when it’s dark. Easily change the color right in the app for soothing or dramatic lighting effects. Simply rotate the outer ring to change the brightness.

About the Startup

Describe your product in 3 words.

Comforting, enlightening, beautiful.

Where did you get the inspiration for your product?

In our previous company, RoboteX, we designed and manufactured first responder robots for hundreds of federal, state, and local government agencies across the world and saw how our robots quickly became an essential part of first responder strategy and tactics. Everything was becoming interconnected and intelligent. We kept thinking about ways we could translate this technology into the consumer space. That’s why, when Adam’s family friend’s house burned down and they lost everything they owned (including their cats), we were deeply affected. If a home had working smoke alarms and Wi-Fi, and its owner had a smartphone, why couldn’t they be alerted when something went wrong? Our friends eventually rebuilt their home. We put together an amazing team, including our chief designer Robert Brunner (former chief designer of Beats by Dre and head of design at Apple) and chief operating officer Charles Huang (founder of Guitar Hero), to build Leeo with the mission of providing beautiful products and services that provide peace of mind and make you say, “Wow."

What differentiates your product from similar products out there?

Leeo is extremely easy to use. Just plug it in and connect to your home’s WiFi. That’s it! And because it listens for the frequency of your existing smoke/CO alarms, you only need 1 for a typical home – much cheaper than replacing all of your existing alarms. It has additional features like millions of hues and temperature/humidity monitoring, too.

Tell us about the best and most challenging parts of the creation process.

We knew we wanted the Leeo Smart Alert to be beautiful – something you'd be proud to display in your home. Even though sensors have become smaller over the years, it was a huge challenge to fit both the sensor technology and power supply into its current form factor. We went through dozens of iterations until we were happy with the size. One of the best parts was working with our chief designer Robert Brunner and chief product strategist Matt Rolandson. Their team brought so much energy and expertise in designing not just a beautiful product, but a striking and enlightening brand. And there’s more to come!
