Green Accelerator
Accelerator
The Green Accelerator (GA) is a Hong Kong–hosted, philanthropy-funded nonprofit platform that prepares scalable, bankable green projects in emerging markets and developing economies (EMDEs). It launched in 2026 at the Hong Kong Green Finance Association Annual Forum, with backing referenced in the Hong Kong SAR Government’s 2026–27 Budget. GA is built around the climate-finance “bankability gap”: many technically viable green projects in the Global South never reach financial close because they lack project preparation, proven operating models, and documentation that meet the investment criteria of multilateral development banks, sovereign wealth funds, and international commercial banks. The platform uses philanthropic capital for design, preparation, technical assistance, and capacity building so proven technologies can be assembled into investable portfolios. Work is organized across energy transition, sustainable food systems, circular economy, and water and climate resilience. A Steering Committee of founding members sets strategy; a secretariat and regional teams run day-to-day operations. Founding members named at launch include the Asian Infrastructure Investment Bank, the Cambridge Institute for Sustainability Leadership, the HKSAR Environmental Protection Department, GenZero, the Institute of Finance and Sustainability, the Silk Road Fund, and HSBC. The initiative is hosted by Sprinkles (HK) Charity Foundation, a Section 88 tax-exempt charity registered in Hong Kong, with listed office locations in Hong Kong, London, and Singapore.

Interledger FoundationNew
Foundation, Grantmaker, Accelerator, Fellowship
The Interledger Foundation is a U.S. nonprofit working to make digital payments more open, affordable, and accessible. It supports open payment technology and funds the developers, researchers, educators, and organizations building on it. Its work began with the Interledger Protocol, created in 2015 by Stefan Thomas and Evan Schwartz. The goal was to help money move between different banks, wallets, currencies, and payment networks as easily as information moves across the internet. The foundation became a nonprofit in 2019 and began operating publicly in 2021. Briana Marbury serves as president and CEO. Stefan Thomas chairs the board, and Evan Schwartz remains a director. The organization is based in San Francisco but has a distributed international team. The foundation supports three main technologies. The Interledger Protocol moves value between different financial systems. Open Payments gives developers a standard way to add payment features to their products. Rafiki provides open-source software that banks, wallets, and other regulated financial institutions can use to connect. The foundation does not charge a fee for using the protocol and has no investors. Grantmaking is also a major part of its work. The foundation reports awarding more than $21 million to over 300 projects across more than 45 countries. Its programs support payment infrastructure, education, research, leadership, public policy, and creative work exploring how financial systems are built. Grants range from small campus awards of up to $5,000 to larger fellowships and accelerator programs offering between $50,000 and $92,000. The foundation reported $96.4 million in net assets and $10.6 million in charitable distributions for the year ending December 2024. This financial base allows it to fund open payment technology and expand access to financial services without relying on protocol fees or outside investors.

NorthX Climate Tech
Accelerator, Impact Fund
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. NorthX is based at Suite 1210, 1066 West Hastings Street in Vancouver and is led by President and CEO Sarah Goodman. NorthX backs physical technologies that can reduce or remove greenhouse gas emissions while producing economic benefits for British Columbia and Canada. Its focus includes energy storage and grid capacity, industrial decarbonization, clean fuels, wildfire prevention and response, carbon management, climate adaptation, and other hardware- and materials-led solutions. 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.
