Analysis
Butterfly Effect, the parent company of AI agent startup Manus, said Thursday it raised more than $500 million in fresh funding, led by Boyu Capital according to most reports (at least one names Bow Capital instead), with IDG Capital among the new backers and existing investors Tencent, HSG Capital and ZhenFund also participating, according to Tech Startups and The Information. It's the company's first round since Chinese regulators forced Meta to abandon its roughly $2 billion acquisition of Manus earlier this year.
How the Meta deal fell apart
Manus launched its AI agent -- a tool that conducts research, builds websites and completes multi-step tasks with limited supervision -- in early 2025, then moved its headquarters and staff to Singapore and took an investment from U.S. venture firm Benchmark. Meta announced its roughly $2 billion acquisition in December 2025 and began integrating Manus's engineers and technology. In April 2026, China's National Development and Reform Commission ordered the deal reversed, saying it had decided to "prohibit foreign investment in the Manus project." Manus's original investors bought back Meta's stake, clearing the way for the company to operate independently again -- a sequence Pulse previously covered as the unwind played out.
“Meta announced its roughly $2 billion acquisition in December 2025 and began integrating Manus's engineers and technology.”
The episode reads as a test case for how far Beijing will let a frontier Chinese AI company fall under American ownership, even when the buyer is as large as Meta. It's a sharper version of the scrutiny Western regulators have applied to Chinese ownership of U.S. tech assets, just running in the opposite direction.
A valuation nobody will confirm yet
Neither Butterfly Effect nor its new investors disclosed a post-money valuation. Bloomberg reported last month that Manus was seeking roughly $4 billion -- about double the $2 billion Meta had agreed to pay -- which would make it China's most valuable independent AI agent company. Reports also disagree on who actually led the round: most outlets name Boyu Capital, though at least one cites private equity firm Bow Capital instead, a discrepancy that hasn't been resolved publicly.
What is better documented is Manus's growth: The Information reported the company's annualized revenue run rate reached $400-500 million by June, up from roughly $100 million in December -- a jump that happened largely while the Meta deal was being unwound, not because of it.
The competitive field just got more crowded
Manus now competes with Meta's own Muse, a personal AI agent app Meta launched in September -- directly rivaling the company Meta tried to buy months earlier. Since separating, Manus has shipped Manus 2.0, built on a proprietary execution system called Cascade, and a standalone agent app called Cue that gives each agent its own email address, phone number and mobile wallet. Other AI labs building similar always-on agents are circling the same market, though none has Manus's specific history of surviving a cross-border forced divestiture.
What the headline number misses: raising $500 million doesn't resolve the valuation question, and a company that just survived a government-forced unwind from its largest backer skipping a post-money disclosure is as much a sign of unsettled internal math as it is of deal momentum. Han Lin, an analyst at The Asia Group, told reporters the company's immediate task is "proving scale, profitability and regulatory alignment" -- three things a funding round alone doesn't prove.
Manus may now pursue a public listing, potentially in Hong Kong, though no timing has been set. For VCs watching the broader pattern, the real signal isn't the dollar figure -- it's that Boyu and IDG were willing to back a company Beijing just finished making an example of, a bet that China's AI nationalism cuts off foreign ownership without cutting off foreign-style venture economics.
