Wuhan Nightingale Technology Co., Ltd

Wuhan Nightingale Technology Co., Ltd was the original company founded by Xiao Hong, named after the nightingale in Oscar Wilde's *The Nightingale and the Rose* — Xiao Hong chose it because the bird acts as a helper in the fairy tale, matching his aim to build useful tools for people . The company later evolved into what became known as Butterfly Effect (蝴蝶效应), the entity behind the AI agent product Manus . In late December 2025, Meta acquired the Manus team in what ZhenFund described as Meta's third-largest acquisition ever, after WhatsApp and Scale AI; post-merger, Butterfly Effect was to remain independently operated at the company, team and product levels while integrating deeply with Meta's core global consumer products . ZhenFund, which backed Xiao Hong from a 2016 hackathon through this ten-year journey, noted that the founder and early partners came from Central China .
