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.

Alterfin is a Belgian social cooperative that finances social enterprises worldwide, focusing on microfinance institutions and sustainable smallholder agriculture organizations. With nearly 6,000 cooperative members, they invest in organizations that help the most disadvantaged people develop economic activities and generate sustainable incomes across Latin America, Africa, and Asia. The organization operates as a cooperative financed by individuals and companies, offering everyone an investment opportunity to generate positive social, environmental, and economic impact. Their mission centers on what they call "Human Yield" - a return measured in improved lives, dignity, resilience, and humanity rather than just financial returns. Alterfin has established itself as a significant player in the impact investment ecosystem over 30 years of operation, with 70.8 million euros in capital and a diverse membership base of 5,711 individual cooperative members and 190 companies and organizations. Their approach enables people to invest in entrepreneurs and farmers they might never meet but whose lives change through access to opportunities in regions where traditional banking channels don't exist or don't meet micro-entrepreneurs' needs.

Amalgamated Bank was founded in 1923 by labor organizer Sidney Hillman and leaders of the Amalgamated Clothing Workers of America with a mission to provide hardworking individuals and their families the same access to quality and affordable banking services that big businesses and wealthy people enjoyed.

The bank aligns finances with values and helps customers create meaningful change for a better world. Amalgamated Bank offers socially responsible investing options, including fossil fuel-free portfolios, and integrates environmental, social and governance (ESG) and sustainability values as a key component of its culture.

Amazon Disaster Relief is an internal Amazon corporate disaster-response initiative. It is not AmazonSmile, not a donor-advised fund, and not a separately incorporated Amazon foundation. Amazon uses its inventory, fulfillment centers, disaster-relief hubs, transportation network, cloud and communications technology, employees, and cash or product donations to support vetted humanitarian organizations before, during, and after disasters. Amazon describes sustained response activity beginning in 2017. The model is predominantly operational and in-kind. Relief hubs pre-position commonly requested items; response teams coordinate with nonprofit and public-sector partners; Amazon transports donated products from its inventory and wish lists; and AWS or technical teams may provide cloud, connectivity, mapping, and recovery support. Announced retail value, item counts, flights, truckloads, and logistics capacity are different from cash grants and should not be added together as a grant total. Amazon's current disaster-relief pages and 2026 response stories show active deployments, including relief shipments tied to floods, fires, earthquakes, and other emergencies. Partners—not the general public—typically identify priority goods and distribution needs. The public Disaster Relief by Amazon portal is a partner logistics mechanism, not a general grant application. No organization-wide open funding round, broadly applicable cheque size, or AUM exists for this internal initiative.
