Manus

Market position

Manus is among the more visible independent autonomous-agent startups, rising to prominence with its March 2025 demo and drawing comparisons to DeepSeek as a Chinese-founded AI company competing globally. It competes with cloud and foundation-model incumbents — OpenAI, Microsoft, Google and Anthropic — that embed agent capabilities into their model and cloud offerings and can subsidize pricing, as well as with coding and app-building tools such as Replit and Lovable, against which the company runs comparison pages. Its role as a Microsoft Agent 365 launch partner converts one incumbent platform into a distribution channel. Reported valuation milestones moved from roughly US$500 million in April 2025 to more than US$2 billion in the announced (and subsequently blocked) Meta transaction.

Manus is positioned as an execution-oriented agent rather than a chat assistant: it plans a task into subtasks and carries them out end to end in its own cloud environment, delivering finished deliverables and working asynchronously so users can close their devices. Its co-founder and chief scientist described it as an autonomous agent bridging conception and execution rather than a chatbot or workflow tool, and the company has claimed advantages over OpenAI's Deep Research in some functionality. Rather than training its own foundation models, Manus builds on Anthropic's Claude models with proprietary context-engineering techniques for prompt scaffolding and memory management; Benchmark's counsel cited the absence of in-house foundation model training in its analysis of U.S. outbound investment rules. Parallelism features such as Wide Research (up to 100 sub-agents) and successive releases that cut average task completion time from about 15 minutes to under 4 minutes are cited as performance differentiators.

Technology

Manus is a proprietary agent layer built on third-party large language models rather than in-house foundation models: Sacra reports it uses Anthropic's Claude models augmented with proprietary context-engineering techniques for prompt scaffolding and memory management, with plan tiers referencing Claude 3.7 Sonnet. Each task runs in a dedicated cloud virtual machine with a web browser, code interpreter, office applications and design engines, allowing the agent to browse, extract and normalize data, generate files and deploy websites. Users can schedule recurring tasks and run multiple parallel workflows depending on tier, and Wide Research orchestrates up to 100 parallel sub-agents. Version 1.5 (October 2025) reduced average task completion time from roughly 15 minutes to under 4 minutes; version 1.6 Max (December 2025) added a Design View.

Go-to-market

Manus uses a freemium, self-serve model: free chat with one-click upgrade to Agent Mode, free trials with limited credits, and paid monthly subscription tiers for individuals and teams. Distribution runs through the web app, Google Play and mobile/desktop apps, a browser extension-style browser operator, and integrations such as Slack. The March 2025 invite-only beta and viral demo video generated a waitlist reported to exceed 2 million users before monetization began. Enterprise distribution is pursued through the team plan, SSO, an API, and a launch-partner position in Microsoft Agent 365 that places Manus workflows inside Microsoft 365 environments. Community programs listed on the site include events, a fellows program, a startups program and a playbook.

Individual knowledge workers and consumers using the agent for work and personal tasks (slides, research, websites, images, games), professional and prosumer users on higher-credit plans, teams buying seat-based plans with pooled credits and SSO, startups via a dedicated program, and enterprises deploying Manus workflows inside Microsoft 365 or embedding them via the API.

Geography

Headquartered in Singapore, with the developer entity Butterfly Effect Pte. Ltd. listed at 109 North Bridge Road, #05-21 Funan, Singapore 179097. The company previously operated from Beijing and Wuhan, and the original Beijing Butterfly Effect Technology remains a Chinese-registered company. As of December 2025 staff were spread across Singapore, Tokyo and San Francisco, with a Paris office planned. The product targets markets outside China — primarily North America, Japan and South Korea, with expansion plans cited for the U.S., Japan and the Middle East — and access from mainland China has been blocked. The website is offered in more than a dozen languages.

History

Xiao Hong founded Butterfly Effect in 2022, two months before the public launch of ChatGPT, with offices in Beijing and Wuhan and a focus on markets outside China, primarily North America, Japan and South Korea. In 2023 the company released Monica, a ChatGPT-powered browser extension aggregating multiple commercial large language models for translation, summarization and writing. In 2024 ByteDance approached Butterfly Effect with an acquisition offer of about US$30 million, which Xiao declined. Development of Manus began in October 2024, and the agent launched in invite-only beta on March 6, 2025. After the April 2025 Series B, the company relocated its headquarters from Wuhan and Beijing to Singapore; roughly 40 of about 120 China-based employees moved and the rest were laid off, Chinese-language social accounts were closed, mainland access was blocked and a planned Chinese version with Alibaba's Qwen team was shelved. In December 2025 Meta announced an agreement to acquire Manus at a reported valuation above US$2 billion; China's Ministry of Commerce opened an investigation in January 2026 and the National Development and Reform Commission blocked the deal on April 27, 2026, with Meta completing an operational separation by June 2026.

Risks & controversies

The Benchmark-led Series B was reviewed by the U.S. Treasury Department in May 2025 under the Outbound Investment Security Program covering AI investments in countries of concern; Benchmark's outside counsel concluded the investment fell outside the program's requirements because Manus does not train its own foundation models and Butterfly Effect is incorporated in the Cayman Islands, and scrutiny receded after the move to Singapore. The founders declined investment offers from several Chinese local governments in 2025, citing concerns that domestic government ties would complicate Western markets. The Meta acquisition triggered a Chinese Ministry of Commerce investigation, exit bans for executives under scrutiny, and an NDRC order to withdraw the transaction in April 2026. The relocation to Singapore involved laying off most of roughly 120 China-based employees. Product criticism includes early reports of crashes, unfinished feel and task-execution delays attributed to limited compute during scaling, and recurring user complaints about credit-based pricing, rapid credit consumption and trial credit allocations.
