A better world, built with better teamwork

We bring Atlassian's funding, tools and teamwork expertise to help nonprofits drive greater impact.

Our mission

Atlassian's mission is to unleash the potential of every team. The Atlassian Foundation extends that mission to teams solving the world's hardest problems.

Atlassian Foundation – Open Call for Proposals

The Atlassian Foundation is deploying US$8 million over the next two years to help disadvantaged learners thrive in the AI era. If you're driving collective action in this space, we want to hear from you.

Reshaping education for the AI era will take teamwork

The Atlassian Foundation focuses on education because it's the most empowering force in the world – it's the key to breaking cycles of poverty and disadvantage.

But that key is slipping out of reach for far too many. UNESCO estimates that more than 250 million children are out of school. And for those in the classroom, learning isn't guaranteed: 57% of children worldwide (nearly one billion) lack the basic skills they need for the era they're growing up in. AI can expand access and accelerate learning. It can also widen inequality where it lands unevenly.

No single organisation can tackle a challenge this complex. That's why the Atlassian Foundation is backing collective action: coordinated efforts by multiple players to solve shared problems at scale. Atlassian's mission is to unleash the potential of every team, so we're uniquely positioned to power these efforts. We've spent 20+ years learning what makes teams work well together, and we're offering that expertise – plus our funding, tools and hands-on support – to help collective action initiatives drive greater impact.

We believe a better world is built with better teamwork, and collective action is teamwork at its most ambitious. Together, we want to shape a future where emerging technology closes gaps for learners the current system leaves behind, rather than widening them.

About this open call

In this open call, we're seeking partnerships with collective action initiatives that are working to improve education for disadvantaged learners in the AI era.

What our partners will receive

Each partnership will include:

The Space Technology Research Institutes program, part of NASA's SpaceTech REDDI initiative for FY 2026, aims to advance innovative space technologies that meet critical needs.

Arnold Ventures

Overview

Arnold Ventures (AV) is a philanthropy dedicated to improving the lives of Americans through evidence-based policy solutions that maximize opportunity and minimize injustice. We focus on improving systems where outcomes are falling short, incentives are misaligned, and the time is right for change.

To advance this mission, we invest in rigorous research to better understand the root causes of problems and strengthen the evidence base on what works to solve them. Using this evidence, we advocate for policy reforms and help build durable, bipartisan coalitions for lasting change.

Request for Proposals

Causal Research on the Impacts of K-12 School Policies 

The next several years present an important opportunity to shape the future of state K-12 education policy. States are making consequential decisions about curriculum, assessment, and accountability systems; school choice and governance policies; and teacher and leader workforce policies. High-quality research in these areas will help policymakers distinguish between reforms that are merely appealing and those that meaningfully improve student outcomes over the long term.

Through this request for proposals (RFP), Arnold Ventures seeks to support research studies that estimate the causal effects of actionable, politically viable U.S. K-12 education policies that can be influenced at the state level and have the potential to improve outcomes at scale. Competitive proposals should employ rigorous causal research methods and, where feasible, examine not only short-term educational outcomes but also longer-term impacts on postsecondary and/or labor market outcomes using administrative data. Given the pace of state policymaking, we place a high value on research that can inform decisions quickly and will give preference to studies that can be completed within 18 months of project kickoff and/or produce actionable findings by the end of 2028.

Fall 2026 Early Childhood Education Funding Cycle

Overall Early Childhood Education Program Blueprint

The Stranahan Foundation’s Early Childhood Education grant program supports efforts to improve access to high-quality early care and education for young children (birth to five), especially those from low-income families. We do this by investing in strategies that strengthen, support, and retain a high-quality, thriving early educator workforce.

The Foundation has a history of supporting professional development (PD) and learning systems through its Provider strategy (). We believe strong professional development systems are essential for building a skilled early childhood workforce and creating positive learning environments for young children.

The Fall 2026 funding cycle is available for organizations that align with this Provider strategy.

Funding Opportunity

This funding opportunity will provide up to $750,000 to support early childhood education providers in strengthening existing professional development (PD) systems. Funding is intended to improve a specific area of an established PD system—not to build a brand-new system from scratch or put the foundational elements in place.

What kind of improvements can funding support?

Organizations should focus their projects on strengthening their professional development systems. The Stranahan Foundation defines a strong professional development system as one that includes:

• Connect learning opportunities that build on one another over time.
• Use adult learning best practices.
• Align staff learning to educator competencies, credentials, career growth, or compensation.
• Provide learning experiences that are individualized, scaffolded, and responsive to educators’ needs, experience, and goals.
• Have dedicated leadership and organizational capacity to support ongoing implementation.

• Gather regular feedback from staff and families.
• Use standardized assessment and evaluation tools to understand what is working and where improvements are needed.
• Make ongoing improvements based on what is learned.
• Support reflective practice, peer learning, and collaborative inquiry among educators.

• Offer both individual and group learning opportunities, such as training, professional learning communities, coaching, and mentoring.
• Provide learning opportunities on an ongoing basis rather than in a one-and-done situation.
• Connect internal and external learning opportunities to make the best use of available resources.
• Support classroom implementation through observation, modeling, feedback, and continuous improvement cycles.

• Provide learning experiences that are practical, relevant, and easy to apply in daily work.
• Include fundamental topics such as family engagement, effective instruction, developmentally appropriate practice, and classroom management.
• Align with established standards, research, and effective practices in the early childhood field.
• Equip educators to support all learners, including multilingual learners, children with disabilities, and children impacted by trauma or adverse experiences.
