Jonathan Winer is the co-founder and co-CEO of Sidewalk Infrastructure Partners (SIP), a New York-based firm that applies technology to physical infrastructure like power grids, roads, water and digital systems. Backed by Alphabet, Ontario Teachers' Pension Plan and StepStone, SIP has raised close to $1 billion and incubates operating companies such as virtual power plant Renew Home and grid-flexible data center developer Verrus. Before SIP, Winer ran investments for Alphabet's urban innovation platform Sidewalk Labs, founded the Asian clean-energy fund Nereus, and helped build the private equity business at the D. E. Shaw group. He is known for thematic, first-principles investing in what he calls the 'missing middle' between venture capital and traditional infrastructure.
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.
