Sidewalk Infrastructure Partners (SIP)

Sidewalk Infrastructure Partners (SIP) is an infrastructure developer and holding company that builds and operates businesses reshaping how energy and digital systems work together. Founded inside Alphabet in 2017 and spun out as independent in 2019 by Sidewalk Labs veterans Jonathan Winer and Brian Barlow, SIP raised $400 million in 2020 backed by Alphabet and the Ontario Teachers' Pension Plan. It identifies bottlenecks in physical infrastructure, then pairs technology with capital to create new operating companies - most recently Renew Home, a roughly one-gigawatt residential virtual power plant, and Verrus, which designs large-scale data centers that flex their grid draw on demand.
