Mozilla Builders ORCA Contributor Fund

The Builders team piloted the ORCA agreement in Q4 2024 to recognize the work of contributors who have had a sustained impact on Mozilla over the years. Our first $5,000 fund recognized two contributors, Tim van der Meij and Jonas Jenwald, from the PDF.js community. Their work has had a significant impact on the project, and each contributor received a $2,500 ORCA award.
