What Zero Hour does
Zero Hour is a youth-led 501(c)(3) climate movement organization founded in summer 2017 by Jamie Margolin, Nadia Nazar, Madelaine Tew, and Zanagee Artis. It operates as a fiscally sponsored project under Future Incubator, a joint program of Future Coalition (501(c)(4)) and March On Foundation (501(c)(3), EIN 82-0958114). The organization's mission is to center the voices of diverse youth — including Global South, People of Color, Indigenous Peoples, and LGBTQ+ individuals — in climate and environmental justice conversations. It serves young activists and organizers, adult allies, frontline/marginalized communities, and climate justice advocates through advocacy campaigns, training, education, and grassroots organizing. Per the input, the organization employs approximately 40 people and operates with no proprietary technology products.
Zero Hour's product surface is organized around an advocacy and training platform rather than a software product. Core offerings include: a Climate Platform outlining federal policy demands; multi-issue campaigns (No New LNG, No New Offshore Drilling, Divest from Fossil Fuels, End the Era of Fossil Fuels/People vs. Fossil Fuels); events (Youth Climate March, Youth Climate Lobby Day, Youth Climate Art Festival, Youth Climate Summit); the Zero Hour 101 virtual training program (seven weekly sessions on organizing, artful activism, finance, anti-racism, and environmental policy); and an Action Hub providing petitions and divestment resources. The organization maintains international chapter entities (Philippines, Jamaica, Pakistan) and U.S. chapters (e.g., Arkansas) as regional operating arms.
The business model is a donations-only nonprofit. Revenue derives from individual contributions processed through ActBlue (digital) and by mail, with no paid products, services, or pricing tiers. The GTM motion is community-led grassroots organizing — leveraging social media, email, events, chapter networks, and coalition partnerships (including a coalition of 1,200+ groups via People vs. Fossil Fuels). The organization also generates ancillary revenue through a referral partnership with Atmos Financial ($20 per signup). No revenue, ARR, or financial figures are publicly disclosed.

Zero Hour competitors and assessment
Company assessmentDirect peers
- Power Shift Network: U.S. youth-led climate justice network training and mobilizing young organizers. Directly comparable in training-program structure, lobby-day tactics, and target demographic to Zero Hour.
- Earth Uprising: Youth-led climate organization focused on training, education, and policy advocacy. Highly comparable to Zero Hour in target audience, training-program structure, and intersectional climate-justice framing.
- Fridays for Future: Global youth-led climate strike movement founded by Greta Thunberg. Direct peer in mobilizing youth around global climate strikes, sharing the same demographic, mobilization playbook, and donor pool as Zero Hour.
- Sunrise Movement: U.S.-based youth-led climate movement advocating for the Green New Deal. Sunrise is Zero Hour's most direct domestic competitor for youth-activist talent, media attention, and small-donor dollars, with overlapping training and lobby-day programming.
- iMatter: Youth-led climate movement driving local action and lawsuits. Comparable mission, demographic, and mobilization tactics to Zero Hour; competes for the same youth-activist and small-donor pool.
Broad incumbents
- 350.org: Large global climate movement focused on ending fossil fuels. Zero Hour's CPO Natalie Mebane was previously Policy Director at 350.org, illustrating the direct personnel and strategic overlap. 350.org is a larger, more established incumbent in the same advocacy niche.
- Greenpeace USA: Large incumbent environmental advocacy organization. Comparable as a campaign-driven climate advocacy peer; co-founder Madelaine Tew interned at Greenpeace USA, and several senior Zero Hour staff have prior Greenpeace experience.
- Sierra Club: One of the oldest and largest U.S. environmental organizations, with significant climate and fossil-fuel campaign work. Comparable in fossil-fuel advocacy thesis; CPO Natalie Mebane was previously Sierra Club's National Dirty Fuels Lobbyist. Serves as a broad incumbent against which youth-led movements like Zero Hour differentiate.
Emerging players
- Our Children's Trust: Youth-driven legal advocacy organization behind the landmark Juliana v. United States climate lawsuit. Directly comparable as a youth climate plaintiff movement; Zero Hour's platform was built on the scientific foundation laid by Our Children's Trust lawsuits.
- Future Coalition: Fiscal and organizational umbrella of which Zero Hour is a project via Future Incubator. Comparable as a youth-led coalition-builder across progressive causes, including climate, with shared back-office and donor-infrastructure overlap.
