Manus

Overview

Manus is a revolutionary autonomous AI agent platform launched on March 6, 2025, by Butterfly Effect (Monica.Im), a Singapore-based startup. As the world's first truly general-purpose AI agent, Manus goes beyond code generation—it can independently execute research, navigate websites, fill forms, create content, run code, and deploy applications without constant human guidance.

Within just two days of launch, Manus' official website exceeded 10 million visits, with invitation codes being resold for 50,000 yuan on Chinese secondary markets. In April 2025, Manus raised $75 million led by Benchmark at a $500 million valuation. In December 2025, Meta acquired Manus for approximately $2-3 billion, marking one of the most significant acquisitions in the AI agent space.

As of September 2025, Manus reaches 13.9 million monthly visits with millions of registered users globally and generates over $100 million in annual recurring revenue (ARR).

Core Features & Advantages

Autonomous Full-Stack Development

Manus' biggest breakthrough is its end-to-end autonomous development capability:
