About Kumu

Kumu Networks has captivated the wireless industry with its technology innovation that enables new radio and network designs that were previously considered impossible to implement.

Challenging basic assumptions about wireless communication, Kumu Networks’ team created a full-duplex wireless system that transmits and receives on the same frequency at the same time–doubling spectral efficiency. This unique and innovative solution employs software-controlled, self-interference-cancellation technology, eliminating the need for frequency or time division duplexing. In addition to its potential impact on future standards and markets, Kumu Networks’ technology can be used to enhance today’s spectrum reuse and overcome the limitations of hardware-based filters.

Kumu Executive Team

David Cutrer
Chief Executive Officer

Dave is a serial entrepreneur with a strong history of leadership and success in the wireless infrastructure space. Prior to Kumu Networks, Dave was the co-founder of NextG Networks (sold for $1B in 2012 to Crown Castle) and prior to that was a co-founder of LGC Wireless. Both of these companies led to highly successful exits for all shareholders. During the journey to these accomplishments, Dave has developed a 20-year history of building and managing great teams, developing great products and working closely with customers to ensure their success.

Mayank Jain
Chief Technology Officer

Prior to co-founding Kumu Networks, Mayank was a graduate student at Stanford University where he and his colleagues created the self-interference cancellation technology that led to Kumu’s formation. Mayank authored more than 50 patents and publications that have been cited more than 3000 times. Mayank has an MS and PhD in Electrical Engineering from Stanford and a BTech from Delhi University. His past experience includes stints at Qualcomm, NVIDIA, and Texas Instruments.

Joel Brand
VP, Product Management

For over 25 years Joel has actively participated in defining and building infrastructure solutions for the telecom and wireless industries. He previously held executive positions at ConteXtream (acquired by HP), Bytemobile (acquired by Citrix) and Ruckus Wireless (NYSE: RKUS and now part of Arris). Joel holds a B.Sc. and M.Sc. in Engineering from the Israeli Institute of Technology (the Technion) as well as MBA from National University in San Diego.

Steffen Hahn
VP, Engineering

Steffen has long been pushing technology boundaries in the analog semiconductor space. Prior to Kumu Networks, he ran the engineering organizations at Scintera Networks (acquired by Maxim Integrated) and Quellan (acquired by Intersil Corporation) where we already developed RF noise suppressing solutions. Prior to that, at Airgo Networks (acquired by Qualcomm), he miniaturized early MIMO solutions into RFICs. Earlier in his career, Steffen was with Phillips Semiconductors. Steffen holds B.S. and M.S. degrees from RWTH Aachen in Germany.

Jung-Il Choi
Chief System Architect

Initially conceived as his class project at Stanford University, Jung-il and his colleagues first created full duplex radios during his PhD research, which became the technical basis for Kumu Networks that he co-founded. Jung-Il is the author of more than 20 patents around full duplex technology, and his research papers have been cited over 3000 times. Jung-il completed his MS/PhD in Electrical Engineering at Stanford University and his BS in Electrical Engineering at Seoul National University, Korea.

Jeff Mehlman
Director of Engineering

Jeff brings a diverse background in communication and embedded systems. He previously founded an IoT home sensor startup, worked in the automotive industry, and had a short stint at Apple. Jeff earned a B.S. in Electrical Engineering from the University of Massachusetts at Amherst and an M.S. in Electrical Engineering from Stanford University, where he put his Ph.D. on hold to co-found Kumu Networks.
