Manus Parent Butterfly Effect Raises More Than $500 Million From Boyu and IDG in Its First Outside Funding Since Returning to Independence

Butterfly Effect, the parent company of the general AI agent Manus, announced on October 8 that it has closed a new funding round of more than $500 million - its first disclosed outside financing since returning to independent operation on September 1. The round was led by Boyu Capital and IDG Capital, with existing investors Tencent, Sequoia China (HongShan) and ZhenFund all increasing their stakes. The company said hiring across its overseas and domestic operations continues, and shared no further financial details.

Two numbers frame the round. People close to the company told Chinese media the target valuation was around $4 billion - an unconfirmed figure; the company itself has published no valuation. And the last hard revenue number on record is from the company blog in December 2025: annual recurring revenue had crossed $100 million, with a run rate of $125 million. Before this round, the company had raised $75 million led by Benchmark in early days, after moving its headquarters and core team to Singapore.

The announcement lands less than a year after one of the stranger corporate episodes in the agent space. Manus joined Meta at the end of December 2025 in a deal reported at roughly $2 billion; Chinese regulators halted the acquisition in April 2026, and in July the founding team bought the company back at the original price - with early backer Benchmark exiting and Tencent, by media accounts, becoming the largest outside investor. After an open letter to users in August 2026, Manus formally resumed independent operation on September 1. Four weeks ago, on September 28, it shipped Manus 2.0 - rebuilt on the self-developed Cascade agent framework with persistent cloud computers and automation workflows triggered by email, calendar, Slack and Notion events - plus a local desktop client called Manus Studio and a separate personal agent app called Cue.

Cue is the consumer-facing bet: an agent for personal life and work that shares Manus's infrastructure, runs on mobile and desktop, and gives each agent its own identity, email address, phone number, wallet and cloud computer - agents can even be pulled into group chats as participants. The company disclosed that Cue's own launch video was generated by code written in Manus Studio, an early proof of the build-and-run loop it is selling.

The China angle is new. Manus says it is assembling a product team for the domestic Chinese market and that cooperation with domestic model vendors and ecosystem partners is under way, with no launch date disclosed. A Chinese-market product from a Singapore-headquartered company whose overseas product is built on frontier models would be a genuinely different distribution game - and one where Tencent, an existing shareholder, is an obvious partner.

Founder and CEO Xiao Hong (who posts as "Xiaohong") used the 2.0 launch to signal persistence: "I thought our journey would end as a footnote. It turns out there may be a chance to write a chapter." He reaffirmed that "Manus has always been a general agent," comparing the business to selling computers - one machine that serves work, video and games alike. The skepticism he is answering is concrete: model vendors and app companies are absorbing task execution into their own products, and Codex and Claude Cowork did not exist when Manus was born. Whether $500 million buys Manus the window to stay a category of its own - starting with a China launch and Cue's monetization - is what the next year tests.
