Streetlife Ventures

Streetlife Ventures was co-founded in New York by Sonam Velani and Laura Fox, two operators who entered venture capital from the public-sector and infrastructure trenches. Velani previously financed $10 billion of transportation, energy, and water projects at Goldman Sachs and helped develop New York City’s $15 billion Green New Deal at the Mayor's Office. Fox built Lyft's Citi Bike into a $120M ARR business and advised Bloomberg Philanthropies on urban investment strategy. That combined policy, finance, and operating DNA shapes the firm's posture: investing in companies that build climate-resilient urban infrastructure. The firm runs a sector-concentrated venture strategy focused on mobility and logistics, buildings, energy, water and waste, and urban climate adaptation. Streetlife invests in B2B pre-seed and seed-stage companies across North America and Europe that have at least a beta product and two or more pilots. Confirmed portfolio positions span hardware and software across the built environment: Rhizome, an arbitrage platform funding energy retrofits in large residential and commercial buildings; DaisyChain Energy, a hardware-plus-VPP thermal battery system; Harvest Thermal, which lowers tenant energy bills through energy brokering and community solar; and Trainsit, a rail-freight optimization platform that reduces shipment costs by more than 30% and emissions by more than 75%. The geographic footprint includes North American and European startups. Streetlife operates out of New York, and the co-founders have built adjacent platforms to extend their influence beyond the portfolio. Velani launched Climate Tech Cities, a community platform that aggregates climate events and convenes talent through a weekly newsletter and site visits to climate infrastructure projects. Fox serves as an Executive-in-Residence at NYU Stern, where she teaches MBA strategy courses, and sits on the board of Governors Island, the designated test-bed for climate innovation in New York City. Recent activity: Velani continues to expand the Climate Tech Cities network to connect policymakers, engineers, and climate operators with high-growth startups. The structural differentiator is the firm's deliberate straddle of public and private spheres: both managing directors hold deep public-sector experience that gives them visibility into municipal procurement cycles, permitting pathways, and infrastructure project finance, access typically absent from traditional early-stage venture firms. Community building via Climate Tech Cities creates a proprietary sourcing funnel that operates between city agencies, utilities, and startup founders.

Frequently asked questions

Who makes investment decisions at Streetlife Ventures?

Investment decisions are led by co-founders and Managing Directors Sonam Velani and Laura Fox. Velani draws on experience financing more than $10 billion in infrastructure at Goldman Sachs and developing New York City's $15 billion Green New Deal. Fox's operating background includes scaling Citi Bike into a $120M ARR business at Lyft, and she currently teaches strategy to MBAs at NYU Stern.

How does Streetlife Ventures source deals?

The firm's primary proprietary sourcing channel is Climate Tech Cities, a community platform founded by Velani that aggregates climate tech events, publishes weekly newsletters, and hosts site visits to infrastructure projects. The network connects the firm to founders emerging from municipal pilots, public-sector research consortia, and university climate labs across North America and Europe.

What does 'pre-seed and seed stage' mean for their investment criteria?

Streetlife targets companies with at least a beta-stage product and a minimum of two completed pilots, most often selling into B2B urban infrastructure buyers. The firm does not back concept-stage or science-project teams; they require operational evidence that a startup can engage municipal or utility procurement cycles.

Which sectors does Streetlife explicitly invest in?

The firm commits to five urban climate sectors: mobility and logistics, buildings, water and waste, energy, and climate adaptation. Portfolio companies include a rail-freight optimization platform, thermal battery hardware, insurance MGA focused on fortified roofs, and hybrid super-capacitor technology for grid balancing.

Does Streetlife Ventures take board seats or lead rounds?

The co-founders describe their investment style as hands-on and knee-deep, working side-by-side with founders to navigate municipal policy and operational complexity. Whether they lead financings or consistently claim board seats is not publicly stated, but the operating support model suggests active post-investment involvement.

How is the firm connected to public-sector climate policy?

Both managing directors worked in government before co-founding the firm — Velani at the NYC Mayor's Office and World Bank, Fox at Bloomberg Philanthropies — and Fox currently sits on the board of Governors Island, New York City's climate innovation test-bed. This dual public-private literacy shapes their ability to underwrite companies that need to navigate building codes, utility tariffs, and urban procurement.

Does Streetlife Ventures operate as a traditional venture firm or as a family office?

Streetlife Ventures is an asset manager structured as a private equity firm, not a family office. It runs a sector-focused venture strategy across multiple portfolio companies rather than managing a single-family balance sheet.
