Our Mission
At Embr Labs, we're on a mission to improve people's lives through the power of temperature. From a 2013 MIT student project that turned into a successful crowdfund in 2017, to our latest generation of award-winning products today, we've been dedicated to listening closely to the people using Embr Wave for over a decade.
Real-world experiences and insights have been the driver behind building a strong, science-backed body of evidence that proves exactly how impactful temperature can be. Through extensive clinical validation, we've confirmed what our community already knows—that temperature is a natural solution that can be truly life-changing.
