<h2>Background</h2>
The Gates Foundation's Philanthropic Partnerships Team (PPT) mobilizes resources and cultivates champions for global health and development (GH&amp;D), ensuring that philanthropy helps the world's most vulnerable children survive and thrive.
Many people want to make a difference but aren't always sure how to turn that intention into action. Our work helps donors move from interest to impact, working alongside individuals, foundations, advisors, and other sector partners while strengthening the broader systems that support effective giving.
Artificial intelligence (AI) is advancing rapidly, reshaping how people access information, make decisions, and engage with the world. For philanthropy, this creates an opportunity to rethink how AI can help donors discover causes and move from interest to action at moments when it matters most.
To explore this opportunity, PPT is launching the AI to Accelerate Charitable Giving RFP to explore how AI can strengthen philanthropic practice and unlock new possibilities for generosity. The Challenge aims to enhance human decision-making with AI-powered tools, data, and insights that help donors give more and give sooner.
<h2>The Challenge</h2>
We are seeking applications and use cases of AI that address the core question: How might AI support donors to give more and give sooner?
This RFP is focused on supporting donor-facing applications and underlying systems of giving that test and demonstrate bold, innovative applications of AI that strengthen and expand philanthropic giving. Desired outputs include generating practical evidence and examples to inform broader practice across the philanthropic sector. We are particularly interested in solutions that increase support for GH&amp;D.
For this RFP, GH&amp;D refers broadly to efforts that improve health, economic opportunity, and human well-being in low- and middle-income countries. Within this field, we are especially interested in efforts that reduce preventable mortality, combat infectious diseases, and expand pathways out of extreme poverty, consistent with the <a href="https://www.gatesfoundation.org/ideas/articles/core-mission-child-health-success" target="_blank" rel="noopener noreferrer">Gates Foundation's long-term goals</a>.
Projects do not need to focus exclusively on GH&amp;D to be competitive. However, proposals that clearly demonstrate applicability to GH&amp;D challenges, or that generate insights relevant to these priorities, will receive additional consideration. We welcome proposals that address the needs of various donor types including everyday donors, high-net-worth individuals, foundations, or other entities relevant to the challenge areas below.
We invite proposals that address at least one of the following challenge areas:
1. Help donors connect with causes and understand where to give to achieve their giving goals
How can AI help people discover causes they care about, understand why they matter, and see where their giving can make a meaningful difference?
Many donors want to give but struggle to navigate a crowded and complex landscape of causes, organizations, and appeals. Geographic distance, limited context, and uncertainty about effectiveness can make it difficult to decide where to focus funds or where to begin.
We seek solutions that help donors make sense of their options, connect their values to specific opportunities, and build confidence that their contributions can make a meaningful difference across a range of issue areas, including GH&amp;D. Examples include:
<ul>
<li>AI-powered recommendation engines that match donors to issues they care about</li>
<li>Personalized learning tools that adapt content, depth, or recommendations as a donor's understanding, interests, and confidence evolve over time</li>
<li>Immersive or narrative tools that make global issues feel human and relatable</li>
<li>Applications that help donors visualize the impact their dollars can create</li>
</ul>
2. Turn interest and intent into donations
How can AI create pathways to help people move from motivation to meaningful contribution?
Many people are motivated to contribute yet fail to follow through because the giving process feels complex, overwhelming, or uncertain.
We seek solutions that reduce friction, enable follow-through on the intention to give, and foster sustained engagement beyond a single transaction. Examples include:
<ul>
<li>Tools that simplify logistical barriers to giving such as cross-border vetting, due diligence, or compliance challenges</li>
<li>Systems that build community or shared motivation among donors</li>
<li>Designs that make giving feel clear, safe, and meaningful</li>
</ul>
3. Develop the foundational systems and infrastructure that enable AI-powered giving
How can we ensure that AI systems reflect accurate philanthropic data and values so that giving and social impact are part of the information people access every day?
As AI increasingly shapes how people learn and make decisions, philanthropy must be represented in the underlying data and tools that drive these systems.
We seek focused, practical projects that ensure philanthropic data is visible, credible, and usable by AI systems in ways that support donor understanding, confidence, and giving. Examples include:
<ul>
<li>Data pipelines or open standards that expose charitable data to algorithms</li>
<li>Training models to better recognize and contextualize social impact</li>
<li>Applications that make nonprofit websites and payment platforms more interoperable with AI agents (i.e. enabling agents to donate to nonprofit organizations)</li>
<li>Solutions that detect and prevent fraud or misuse in donation processes supported by AI</li>
</ul>
AI Ethics and Responsibility
The Gates Foundation is committed to harnessing AI for social good while mitigating risks such as bias, inequity, and potential harm, particularly to vulnerable populations. As AI-enabled tools increasingly shape how people access information and make decisions, ethical and responsible use of AI is a foundational consideration that should inform how solutions are designed, tested, and deployed.
Applicants are not required to submit a separate response on ethical and responsible AI considerations. However, proposals should demonstrate thoughtful awareness of ethical issues as part of the project's learning and experimentation process, including how potential risks may evolve as systems are tested with real users. The Foundation may request clarification during the application review process as needed.
In evaluating proposals, reviewers will consider alignment with the Foundation's AI principles, which are summarized below:
<ol>
<li>AI efforts should align with the Foundation's mission to improve health, reduce poverty, and expand opportunities for those facing the greatest challenges.</li>
<li>AI solutions should be informed by the needs and perspectives of the community they are intended to serve.</li>
<li>Potential risks and unintended harms should be identified and addressed throughout the AI lifecycle, including monitoring for unintended consequences.</li>
<li>Personal and sensitive data must be handled responsibly and protected from misuse.</li>
<li>AI solutions should be designed for broad benefit and be accessible and usable in their intended contexts.</li>
<li>Be transparent about how AI is used, including its purpose, limitations, and governance.</li>
</ol>
Funding Level
We will consider applications requesting awards up to $150,000 USD per project, with a grant duration of up to 1 year. Budgets should align with the scale and complexity of the proposed work. Indirect costs are allowable and should be included within the total requested funding (subject to the Gates Foundation's <a href="https://docs.gatesfoundation.org/documents/indirect_cost_policy.pdf" target="_blank" rel="noopener noreferrer">indirect cost policy</a>).
