May 2020Series AAlphabet (lead); Ontario Teachers' Pension Plan (lead)$400M-Sidewalk Infrastructure Partners (SIP) is a holding company spun out from Alphabet's Sidewalk Labs, launched in August 2019 to own, operate, and invest in advanced infrastructure projects focused on future-proofing mobility, energy, water and waste, digital infrastructure, and social infrastructure. The company applies technology to create sustainable, intelligent urban solutions, such as stormwater management, neighborhood-scale heating and cooling, and advanced traffic controls, while convening investors, policymakers, and academics. Co-led by CEOs Jonathan Winer and Brian D. Barlow, SIP started with 15 employees including finance experts, data scientists, and technologists, with plans to expand. In May 2020, SIP raised a $400 million Series A funding round from anchor investors Alphabet and Ontario Teachers' Pension Plan, marking one of the largest early-stage rounds at the time for a company less than a year old. The funding supports investments in technology-enabled infrastructure, with an early example being an investment in AMP Robotics, which develops cost-effective recycling sorting robotics. Returns are expected on a multi-year horizon, longer than typical VC but not multi-decade. SIP leverages the expertise of its partners: Alphabet and Sidewalk Labs provide technology capabilities, while Ontario Teachers' brings infrastructure and investment acumen. The initiative aligns with broader trends in intelligent infrastructure amid challenges like those faced by Sidewalk Labs' Toronto Quayside project, which encountered political and privacy pushback.
