Butterfly Effect, the parent company of AI agent startup Manus, said October 8 it has completed a funding round of more than $500 million — its first since resuming independent operations after Beijing ordered Meta to unwind its $2 billion-plus acquisition in April.

The round was co-led by Boyu Capital and IDG Capital, with Tencent, HSG Capital and ZhenFund participating. Media reports put the valuation at roughly $4 billion, double the price Meta agreed to pay in December 2025.

Manus builds general-purpose AI agents that autonomously carry out tasks with minimal human input, and in September launched a standalone personal-agent app called Cue. The Information reported in June its annualized revenue run rate had surged to about $500 million — a fivefold increase since the Meta acquisition — and that the company is eyeing a Hong Kong listing no earlier than 2027.
