McKinsey has built an autonomous agent that reduces client onboarding time by as much as 90%.

Judge as of 2024-11-19. True: by that date McKinsey had built an AI agent described as autonomous (or agentic, acting without step-by-step human direction) for client onboarding, and McKinsey or Microsoft materials report that it cuts onboarding time by up to about 90%. Mostly true: such an agent existed and was reported to cut onboarding time, but the stated maximum was somewhat different (for example 80–89%), or the agent was in pilot rather than fully deployed. Mixed: an agent existed but its link to onboarding or its reported time saving was only partly as stated. Mostly false: McKinsey had an AI tool related to onboarding, but it was not an autonomous agent, or the reported saving was far below 90%, or 90% referred to a different metric. False: evidence shows no such McKinsey agent existed as of that date, or the figures clearly contradict the claim.

   “At consulting firm McKinsey & Co., an AI agent now handles the tedium of client onboarding. It coordinates paperwork, shares relevant contact details, affirms the scope of the project — and runs everything by the firm’s legal, risk, finance, staffing and other departments to get their signoffs.”

   “In the past, onboarding required tens of hours per new client. Now, “an agent basically does all that chasing for you,” and completes the process in roughly 30% of the time.”

Microsoft posts from 2024-10-21 and 2024-11-19 say McKinsey "is creating" an agent to speed up client onboarding, and that "the pilot showed lead time could be reduced by 90%" (E1, E2). E2 sits in a post about autonomous agent capabilities. This matches the claimed agent and the 90% figure, but it describes a pilot still being built, not a finished deployment. A later independent article confirms McKinsey had an AI agent coordinating client onboarding across departments (E3), although it cites a different measure: completing the process in about 30% of the time (E4). The criteria rate a pilot-stage agent as mostly true.
