Mike Krieger, co-founder and former CTO of Instagram, has joined Anthropic as Chief Product Officer. Krieger will lead the AI company's product development and expand the availability of the AI chatbot Claude. He has a lot of experience in building scalable products: At Instagram, he grew the development team to over 450 employees and scaled the platform to over one billion users. Most recently, Krieger developed the personalized news app Artifact for three years before it was acquired by Yahoo. Anthropic CEO Dario Amodei sees Krieger's background in developing intuitive products and user experiences as a valuable contribution to the company, particularly in designing new ways of interacting with Claude in the workplace.
