Butterfly Effect, the parent company of AI agent developer Manus, announced on October 8, 2026, that it had secured more than $500 million in new financing. The round was co-led by Boyu Capital and IDG Capital, with participation from several longstanding investors. The investment comes shortly after Manus returned to independent operations following the reversal of its acquisition by Meta.
Funding Details and Valuation
Existing investors Tencent, HSG, formerly known as Sequoia China, and ZhenFund joined Boyu Capital and IDG Capital in the new round. Butterfly Effect did not specify how the proceeds would be allocated or disclose the company's post-financing valuation. The funding therefore confirms substantial investor backing without establishing a new publicly verified price for the business.
Reports published in September suggested that Manus was discussing a roughly $500 million raise at a valuation of approximately $4 billion. That figure reflected fundraising negotiations rather than the final terms confirmed in October. The distinction is important because the company has not publicly validated the proposed valuation or provided an ownership breakdown for its latest investors.
Returning to Independent Operations
Manus announced plans to join Meta in December 2025 through an acquisition reportedly valued at more than $2 billion. However, Chinese regulators intervened in April 2026 and required the transaction to be unwound. The reversal returned the AI startup to a standalone operating model after months of uncertainty surrounding its ownership.
On September 1, Manus formally confirmed that it had resumed independent operations under its founding team's leadership. The transition involved data-management changes for some customers, including required backups and restoration procedures linked to regulatory obligations. In an earlier notice, the company explained that certain user data generated after December 29, 2025, would need to be deleted.
Manus Expands Its AI Products
Founded in 2022, Butterfly Effect introduced Manus in March 2025 as a general-purpose AI agent capable of performing multistep assignments. Its software is designed to assist with research, writing, coding, and other workflows that ordinarily require users to coordinate multiple tools. The company has continued developing these applications since resuming independent operations.
On September 28, Manus unveiled Manus 2.0, an updated platform built around its Cascade agent execution system. The release introduced improvements to its workspace, creative tools, cloud computing capabilities, and event-triggered automation features. These additions are intended to help users manage more involved projects and connect AI-generated work with practical execution.
The company also introduced Cue, a separate application designed for personal AI agents operating across digital services. According to Manus, individual agents can have their own email addresses, phone numbers, digital wallets, and computing environments. The system allows users to delegate communications, coordinate tasks, and authorize payments within budgets they control.
Expansion Plans
Alongside its funding announcement, Butterfly Effect signaled continued recruitment and efforts to develop products for customers in China. Reports in Chinese media described plans to work with domestic AI model providers and other ecosystem partners. These initiatives would complement the company's existing international products as it establishes its next phase of operations.
The fresh financing arrives as developers of AI agents seek to move beyond demonstrations toward useful, repeatable applications. Manus is pursuing that goal through products that combine autonomous task execution with user oversight. The company has not yet provided detailed spending targets or financial projections tied to the new capital.
Butterfly Effect's more than $500 million raise represents a major financing milestone following Manus's return to independence. Support from new and existing investors gives the company additional resources to advance its products and hiring plans. Its next challenge will be translating those investments and recent launches into sustained adoption across the markets it serves.
