About Us

Expand Your Vision

Vayyar develops safe, mobile, low cost 3D imaging sensors, enabling applications ranging from breast cancer screening to detecting water leakage, people tracking, vital signs, and more.

Founded in 2011 Vayyar started with the vision to develop a new modality for breast cancer detection by using RF to quickly and affordably look into human tissue to detect malignant growths. As the technology matured and evolved, Vayyar leveraged it to open up new capabilities and widen its application scope to additional markets including smart home, security, automotive, retail, elderly care, construction, agriculture and more.

Vayyar facilitates long-term partnerships with corporations to develop tailored solutions to meet specific needs. It also provides off-the-shelf development kits to give companies hands-on experience and the ability to develop applications in-house. Vayyar has its own line of consumer products launched under the ‘Walabot’ brand.
