Camille François is the founding president of ROOST (Robust Open Online Safety Tools) and a professor of practice at Columbia University’s School of International and Public Affairs.

She has held senior trust and safety and research roles across social media, cybersecurity, and gaming — including Principal Researcher at Google, Senior Director at Niantic, and Chief Innovation Officer at Graphika. She is known for building high-performing teams to detect and mitigate online harms at scale, from child safety to violent extremism, and her research has helped shape safety practices across major Silicon Valley platforms.

Her public interest work includes investigating information operations for the U.S. Senate Select Intelligence Committee, leading France’s governmental inquiry into immersive technologies, and being appointed by President Emmanuel Macron to co-chair the national consultative assembly on the future of the information society. Her current research focuses on public interest AI and new open source practices.

Recognized by TIME’s “100 Next,” MIT Tech Review’s “35 Under 35,” Fast Company’s “Most Innovative Companies,” and the World Economic Forum, she is also a Fulbright Scholar and a Young Leader of the French-American Foundation. She is affiliated with the Harvard Berkman-Klein Center and the French Institute of Geopolitics, and her work has been featured in The New York Times, The Washington Post, WIRED, and Le Monde.

Anne Bertucio is the Chief Operating Officer of ROOST (Robust Open Online Safety Tools), where she leads operations and strategy to advance a commons of open source safety technology. Her career has centered on the intersection of technology and societal progress — a focus that led her to open source software as a force for transparency and collaboration.

Prior to joining ROOST, Anne led Google’s Open Source Programs Office, where she oversaw the release and support of Google’s open source projects and championed programs that improved the long-term sustainability of open source ecosystems. Her work emphasized security and privacy, including authoring and publishing Google’s coordinated vulnerability disclosure (CVD) policy — a framework that later informed policies for the Cloud Native Computing Foundation and the Open Source Security Foundation.

Anne brings a multidisciplinary perspective to her leadership, grounded in training in policy and ethics and experience spanning government relations, community management, and both the nonprofit and private sectors.

Juliet Shen is the founding Head of Product at ROOST (Robust Open Online Safety Tools), where she leads the development of scalable technologies that protect people online while preserving user privacy. She was instrumental in incubating ROOST within Columbia University’s Trust and Safety Tools Consortium and now oversees its product vision and implementation.

Over the past decade, Juliet has shaped trust and safety practices across some of the world’s most widely used platforms. She served as Snapchat’s first Trust and Safety Product Manager, helping establish its foundational moderation systems; led the Trust and Safety product team at Grindr; and deployed advanced AI at Google to detect and prevent abuse across Workspace platforms at scale.

Juliet has also been a driving force behind industry collaboration. She co-chaired the Tech Innovation Working Group at the Technology Coalition, where she helped launch Project Lantern — the first-ever cross-platform child safety signal-sharing program — and currently co-chairs the Tools Research Committee at the Trust and Safety Foundation. She holds Bachelor’s degrees in Political Science and Sociology from the University at Albany.

Vinay Rao is the Chief Technology Officer of ROOST (Robust Open Online Safety Tools), where he leads the design and development of an open source, interoperable software stack that raises the bar for online safety across the technology ecosystem.

He has spent nearly two decades advancing the field of online safety. Most recently, he served as Head of Safeguards at Anthropic, where he built systems to monitor AI usage and ensure safe deployments — developing infrastructure, classifiers, monitoring systems, and review tools to mitigate harmful content and behavior.

Earlier in his career, Vinay led safety and security engineering teams across ads, payments, social media, and the sharing economy. At Google, he built early defenses against click fraud; at Airbnb, he developed tools and processes to prevent property damage and physical harm; at Stripe, he launched merchant fraud and credit risk models; and at YouTube, his teams defended against coordinated and adversarial abuse at scale.

Before transitioning into Trust and Safety, Vinay held R&D roles at Synopsys and Schlumberger, modeling materials from fluid mechanics to semiconductors. He holds a Ph.D. and M.S. in Engineering from Stanford University and a B.Tech from the Indian Institute of Technology, Bombay, where he received the Institute Silver Medal.

Eli Sugarman is a co-founder of ROOST and Director of the Special Projects at the William and Flora Hewlett Foundation. Eli brings a wealth of experience working at the intersection of security and emerging technologies, as well as deep knowledge of philanthropic strategy. He supports the Foundation president by focusing on unique catalytic opportunities, collaborative grantmaking, and exploring new areas of work.

Most recently, Eli served as a senior fellow with the Special Competitive Studies Project, a Schmidt philanthropy, where he worked on projects related to technology policy, cybersecurity, AI, and co-founded ROOST (Robust Open Online Safety Tools). Prior to that, he served as Vice President at the Meta/Facebook Oversight Board, an experimental online safety accountability mechanism. Eli also previously served as Director of the Hewlett Foundation’s Cyber Initiative, a ten-year, $160 million grantmaking effort that built a more robust and inclusive cybersecurity policy field. Prior to that, he was senior director at an emerging markets advisory firm based in Washington, D.C., where he provided strategic counsel on international policy, regulatory, and business matters to clients globally. Eli began his career as a foreign affairs officer at the U.S. Department of State, where he focused on international security issues.

He currently serves on the boards of ROOST, the Institute for Security and Technology, Girl Security, and is a member of the Aspen Institute’s Global Cybersecurity Group. A San Diego native and graduate of Middlebury College, he holds a J.D. from Stanford University Law School.
