Butterfly Effect Raises $500M for Manus After Meta Buyout Unwinds

Butterfly Effect raised more than $500 million in a funding round led by Boyu Capital and IDG Capital, with participation from existing investors Tencent, Sequoia China, and ZhenFund, to support evolving the Manus AI agent into an "AI computer." The investment follows Meta's unwinding of its acquisition of the startup and is among the largest in the AI agent sector, where most venture capital has primarily targeted foundation model layers rather than standalone agent tools.
