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.
Brian Barlow is the co-founder and co-CEO of Sidewalk Infrastructure Partners (SIP), the Alphabet spinout that owns, operates, and invests in next-generation energy, mobility, water, and digital infrastructure. He brings three decades of private equity, venture capital, and infrastructure investing - including a stint inside Alphabet's Sidewalk Labs and an early seat at Michael Burry's Scion Capital - to the question of how to fund and build the infrastructure cities actually need. SIP launched in 2020 with a $400 million backing from Google and has since seeded ventures like Renew Home and AMP Robotics.
