OpenAI has appointed Slack CEO Denise Dresser as its first chief of revenue. Dresser will oversee global revenue strategy and help businesses integrate AI into daily operations. OpenAI CEO Sam Altman recently emphasized improving ChatGPT, which now has over 800 million weekly users. Despite its success, OpenAI faces competition from companies like Google and concerns about profitability. The company earns money from premium ChatGPT subscriptions but hasn't ventured into advertising. Altman had recently announced delays in developing new products like AI agents and a personal assistant.
