Experimentation Platform (ExP)<\/strong> is Microsoft\u2019s foundational system for accelerating innovation through trustworthy experimentation. As part of CoreAI, ExP enables every AI builder across the company to design, run, and learn from high-quality A\/B experiments with minimal friction. By combining rigor in experimentation science with modern, AI-driven workflows, ExP embeds experimentation directly into the product development lifecycle helping teams move seamlessly from idea to insight. From large-scale platform investments to developer-centric tooling, ExP empowers engineers, scientists, and product teams to validate hypotheses, measure real-world impact, and safely iterate on intelligent systems that reach billions of users.<\/p>\n\n\n\n

ExP is led by Colin McFarland (opens in new tab)<\/span><\/a>.<\/p>\n\n\n\n
