Earth Day, celebrated globally on April 22, encourages collective action to protect the environment with the 2022 theme "Invest in Our Planet" urging bold action and equitable implementation. Highlighting sustainability efforts, three MongoDB customers exemplify eco-friendly innovation: Germany's University of Bremen uses MongoDB to handle heterogeneous data in research for sustainable materials; Journey Foods leverages MongoDB for its machine learning platform to improve food sustainability and cost efficiency; and Kode Labs utilizes MongoDB Atlas to develop software for sustainable building management. Separately, MongoDB's leadership transition unfolds as CEO Dev Ittycheria announces his retirement effective November 2025, with Chirantan “CJ” Desai named as his successor. CJ, known for his transformative roles at ServiceNow and Cloudflare, is poised to guide MongoDB through its next growth phase, with Ittycheria emphasizing the importance of strategic leadership changes to strengthen the company.
