Airbnb.org is an independent U.S. 501(c)(3) public charity that pays for free, short-term housing for people affected by disasters and other crises. The organization launched in 2020 after eight years of crisis-housing work through Airbnb's Open Homes program, which began when a host named Shell offered her home at no charge after Hurricane Sandy in 2012. Airbnb.org is legally separate from Airbnb, Inc.; Airbnb covers the charity's operating costs, supplies access to its technology platform and services, and says it does not earn money from Airbnb.org-supported stays. The operating model is housing assistance rather than conventional grantmaking. Airbnb.org works with vetted local nonprofit partners that identify and refer eligible people, volunteers, first responders, refugees, and families traveling for medical care. Airbnb.org then funds bookings on Airbnb's platform. Hosts are generally paid as they would be for an ordinary stay and receive AirCover and specialized support; some separately choose to discount a stay, offer it free, or donate a portion of their payout. An Airbnb.org emergency-stay host should therefore not be described as synonymous with Airbnb's broader commercial-host community. Airbnb.org organizes its work around emergency-response stays, medical stays, and resettlement stays. Its official site says more than 60,000 hosts have helped provide housing to more than 250,000 people since the 2012 origin of the program. It separately reports 1.6 million nights of free emergency housing since Airbnb.org launched in 2020. Those are facilitated stays and nights, not a count of unique guests, grants, or dollars deployed. For January through June 2026, Airbnb.org reported 87 disaster responses, more than 28,000 nights provided, and 5,776 hosts who donated. It also reported that an Airbnb.org booking cost an average of US$110 per night globally over the preceding five years. These organization-reported operating measures show delivery capacity, but they are not assets under management, audited grant expenditures, or a committed funding pool.

Beneficial State Bank is an FDIC-insured, state-chartered community development financial institution (CDFI) headquartered in Oakland, California, with branches in California, Oregon, and Washington. Kat Taylor and Tom Steyer founded it in 2007 as a triple-bottom-line community bank and donated the capital to Beneficial State Foundation, a nonprofit that is now the majority owner of the bank’s capital. That ownership is the lock: the institution is meant to stay governed in the public interest rather than recapitalize through a conventional holding-company sale. Causeartist indexes it in the funders directory as a CDFI bank and debt provider, not as a venture fund. The product is credit: deposits become loans for affordable housing, nonprofits, small businesses, and environmental projects on the West Coast. CDFI rules require at least 60% of financing to low- and moderate-income or underserved communities; the bank reported that 100% of its 2025 loan portfolio upheld that community-development mandate. It will not lend to fossil fuels, private prisons, or weapons manufacturing, industries it calls “contra mission.” It has been a Certified B Corporation since 2012 (B Lab directory; the bank’s certifications page also cites 2013), is Fossil Free Certified, belongs to the Global Alliance for Banking on Values, and describes itself as the only unionized community bank in the U.S. As of year-end 2025 it reported $1.98 billion in assets, $1.67 billion in deposits, $1.47 billion in outstanding loans, and 15.4% net loan growth. Those figures are company-reported from the 2025 Impact Report, not an independent audit.

NorthX Climate Tech is an independent Canadian nonprofit investor and commercialization catalyst for climate hard tech. Founded in October 2021 as the BC Centre for Innovation and Clean Energy (CICE), it launched with $105 million in commitments from the Government of British Columbia, Shell Canada, and the Government of Canada through Natural Resources Canada’s Energy Innovation Program.

The organization targets the commercialization gap between technical promise and market deployment, especially projects at technology readiness levels 4–9. Funding is non-dilutive and tailored by opportunity: NorthX says investments may be repayable or non-repayable, with approved Open Intake projects receiving milestone-based reimbursement funding. Support extends beyond capital to technical validation, lifecycle assessment, investor and industry introductions, market readiness, and follow-on funding. NorthX reports that, by May 2026, it had backed more than 74 projects with over $57 million and helped catalyze more than $600 million in follow-on investment. Those figures are reported by NorthX and are not presented as independently audited outcomes. The Women in Climate Tech initiative adds a gender-lens pathway for capital-intensive climate ventures. In September 2026, NorthX reported that more than $36 million had been committed across 45 projects at companies with women in leadership—over 58% of its total capital commitments—and that those investments had unlocked more than $430 million in additional capital.

The Home Depot Foundation is the U.S. corporate foundation associated with The Home Depot, established in 2002. Its current mission centers on improving the homes and lives of U.S. veterans, training people for skilled trades and helping communities recover from natural disasters. Foundation grants should be distinguished from The Home Depot's retail donations, Team Depot volunteer labor and in-kind building materials, even when several forms of support appear in one project. The Foundation reports that since 2011 it has invested more than $650 million in veteran causes and improved more than 70,000 veteran homes and facilities. It has pledged to invest $750 million in veteran causes by 2030 and $50 million in skilled-trades training through Path to Pro. These are organization-reported cumulative investment, improvement and forward-commitment figures, not AUM, cash on hand, independently verified housing outcomes or amounts available in a current application cycle. Its Veteran Housing Grants Program is a genuine public proposal route for eligible 501(c)(3) organizations developing or rehabilitating multifamily permanent supportive housing for veterans. The official page says proposals are accepted year-round, lists three 2026 decision cycles and states typical program awards of $100,000 to $500,000. Because that range applies only to this specialized program rather than all Foundation grants, the database's general check-size fields remain empty; the detail is preserved in eligibility and decision sections.
