Developer of SerDes IP.


Kandou Bus designs high-speed, pin and energy efficient chip-to-chip links, SerDes, and associated technologies.

The company’s key technology is Chord signaling. According to the company, the technology delivers 2-4x more bandwidth while consuming half the power or less of traditional differential signaling. Chord signaling is a generalization of differential signaling. Whereas differential signaling is used to transmit a single bit across two correlated wires, Chord signaling transmits multiple bits over multiple correlated wires without paying the price of reduced margin that is common with other signaling methods such as PAM-4.

In July 2018, Kandou Bus completed its Series B investment round with a $15M investment from Bessemer Venture Partners and Walden Investment.

In July 2016, Kandou Bus raised $15M from Bessemer Venture Partners.

The company originated as a spinoff from EPFL in 2011, founded by Amin Shokrollahi and Harm Cronie.
