SF Climate Week

What SF Climate Week does

SF Climate Week is a nonprofit, community-powered climate summit organized by Climatebase (the primary organizer) and the Climate Week Network in the San Francisco Bay Area. Founded in 2023, the entity functions as a coordination layer that aggregates independently organized climate-themed events under a unified brand during a week-long period each April. It serves climate-focused nonprofits, climate-tech companies and startups, government officials and policymakers, climate investors (including Generation Investment Management, Kleiner Perkins, and Lowercarbon Capital), and the general public. Attendance is free, and from an inaugural 2023 program of roughly 100 events drawing 7,000 attendees, the event scaled to 750+ planned events with 1,000+ speakers and an expected 75,000+ attendees for the April 18–26, 2026 edition, branded as California's largest climate summit.

The core offering is a decentralized event calendar and registration platform built on third-party infrastructure: Lu.ma for event listings, ticketing, and registration, and Airtable for the speaker referral database, volunteer management system, sponsorship coordination, and venue matching service. There is no proprietary software product; differentiation rests on convening power and the breadth of the partner ecosystem, which includes the City of San Francisco as official partner, 9Zero Climate Innovation Hub as the official hub at 350 California Street, BART as the official transit partner, and flagship partners such as Project Drawdown, Grist, S&P Global, the California Academy of Sciences, Oakland Roots SC, and the Trust for Public Land.

Revenue derives principally from sponsorship packages sold to mission-aligned corporations and foundations, paid admission for select individual events, and paid promotional packages that event organizers can purchase for heightened visibility on the SF Climate Week calendar. Confirmed sponsors include Google, Salesforce, Deloitte, SE Ventures, Rewiring America, Atmos Financial (Platinum), and others; participation for attendees and organizers remains free. The leadership team is shared with Climatebase: Evan Hynes (co-founder and CEO), Justin Hardin (co-founder and CTO, Forbes 30 Under 30 2025), and Jesse Hynes (co-founder and COO, Forbes 30 Under 30 2025).

Expansion highlights5 records

Direct peers

• Aspen Ideas Festival: Multi-day ideas festival convening thought leaders across policy, science, and business with marquee speakers and partner-driven programming. Comparable on convening model, audience mix (policymakers + investors + academics), and sponsorship-driven economics.
• London Climate Action Week: Annual city-level climate gathering with a decentralized model similar to SF Climate Week. Comparable scale and audience composition (policymakers, corporates, climate startups, activists), but geographically distinct — making it a structural peer rather than a direct competitor.
• Climate Week NYC: The flagship US climate convening run by The Climate Group alongside the UN General Assembly. Directly comparable as a city-anchored, multi-stakeholder climate week with hundreds of partner events; SF Climate Week is effectively its West Coast counterpart.
• VERGE / GreenBiz Conference: Leading US climate business conference for corporates, investors, and solution providers. Directly comparable on target audience (enterprise sustainability leaders, climate-tech buyers) and on the role of networking and deal-making within a climate-themed gathering.

Broad incumbents

• Web Summit: Large-scale multi-track conference with global sponsor ecosystem. Comparable on the multi-stakeholder, sponsorship-driven economics of a major convening event, though Web Summit is commercial rather than mission-driven.
• Dreamforce: Salesforce's annual flagship conference in San Francisco. Comparable on Bay Area geography, enterprise sponsorship scale, and the pattern of a single host platform aggregating partner-led sessions, though vastly larger in commercial scale.
• UN Climate Change Conference (COP): The annual international climate negotiation and convening event. Comparable on mission (climate solutions convening) and on the participation of heads of state, investors, and climate-tech leaders, but vastly larger in scope and governmental in nature.
• SXSW: Large multi-track, multi-venue festival with decentralized partner programming and corporate sponsorship model. Comparable on operational structure (hundreds of independently organized sessions under one umbrella brand) and on the convening power required to attract marquee speakers.

Emerging players

• Climate Action Festival (various): A growing set of regional climate gatherings and accelerator summits (including World Economic Forum climate tracks and similar). Comparable on the model of multi-stakeholder climate convening at city scale, but typically narrower in stakeholder mix than SFCW's broad climate-week positioning.

Others

• Climatebase: The primary organizer and operational partner of SF Climate Week. Not a peer in the competitive sense but an enabling platform — provides the 120K newsletter and 70K LinkedIn audience, the Climatebase Fellowship, and shared co-founders that power SFCW.
