Vayyar, a company developing radar-imaging sensor technologies, today announced that it raised $108 million in a Series E round led by Koch Disruptive Technologies, with participation from GLy Capital Management, Atreides Management LP, KDT, Battery Ventures, Bessemer Ventures, More VC, Regal Four and Claltech. The round brings Vayyar's total raised to over $300 million, which CEO Raviv Melamed said is being put toward expanding across verticals and introducing a "family" of machine learning-powered sensor solutions for robotics, retail, public safety and "smart" building products.

"We are pleased and proud to progress our partnership with existing investors including KDT, as well as additional backers which are joining forces with us for the first time," Melamed said in a statement. "During a challenging period for the global economy, this new funding round is a ringing endorsement of our mission and a clear vote of confidence in the strength of our technology and the strategic agility of our organization."

Founded in 2011 by Miri Ratner, Naftali Chayat and Melamed, who was previously VP of Intel's architecture group, Vayyar initially developed its sensor technology to provide an alternative means of screening for early-stage breast cancer. Leveraging MIMO antennas, short for "multiple input, multiple output," Vayyar's products can deliver a high-resolution mapping of their surroundings by sending and receiving signals from dozens of antennas.

Vayyar later expanded its "radar-on-chip" technology from healthtech to a number of other sectors, including automotive, senior care, retail, smart home and commercial property. Vayyar sells Vayyar Care, a fall detection system for monitoring people at higher risk of tripping and falling in bedrooms, bathrooms and other living spaces. In the automotive industry, Vayyar offers solutions for collision warnings, parking assistance, adaptive cruise control, seatbelt detection and automatic breaking. And in construction, Vayyar provides a handheld sensor called Walabot for detecting leaky pipes behind walls.
