The Experimentation Platform (ExP) is Microsoft’s foundational system for driving innovation through trustworthy experimentation. ExP’s mission is to empower every AI builder at Microsoft to accelerate innovation through trusted, low-friction experimentation<\/strong>. By pairing scientific rigor 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 equips engineers, scientists, and product teams to validate hypotheses, measure real-world impact, and safely iterate on the 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
