Gradient started in 2017 as part of Otherlab, a group of inventors, engineers, scientists, and business people striving to impact the energy, robotics, manufacturing, and education sectors. 

Since then, we’ve evolved into a Series A hardware startup in San Francisco, CA making home heaters and air conditioners that are better for the environment, easier to install, and more pleasant to use. 

Our launch product is a window heat pump that users can install in 15 minutes. Unlike with mini-split heat pumps, there's no need to hire an electrician or professional HVAC technician to install a Gradient heat pump. In addition, switching to Gradient doesn't require permitting or drilling, which means our users in older buildings won't disturb mold, asbestos, or lead. 

Our commitment to delivering excellence and making a real difference has garnered recognition and partnerships with some prestigious organizations. We’re proud to have contracted with the New York City Housing Authority (NYCHA) to install 10,000 window heat pumps in NYCHA housing. Moreover, our launch product has been honored as one of TIME's best inventions of 2022, a Fast Company 2022 World Changing Idea, and a winner of the House Beautiful Live Better Awards 2022.

At Gradient, we’re driven by a shared passion for innovation, sustainability, and enhancing the quality of life for individuals and communities alike. Join us as we continue to push boundaries, disrupt industries, and shape a future that’s both environmentally conscious and comfortable.
