Instinct, a personal agent product from Silicon Valley that operates by invitation only, has witnessed a meteoric rise in its valuation, rocketing from $2.5 billion to $10 billion in a short span, and has successfully raised $1 billion in Series C funding. This company, boasting a mere 14 employees, no mobile app, and no marketing budget, adheres to a philosophy of restraint, prioritizing the enhancement of the reliability of agent task execution and generating revenue through transaction commissions. Despite its small user base, Instinct has achieved high card-binding and retention rates. Currently, the personal agent sector has garnered significant investment from several industry giants. Instinct aims to foster network effects by constructing a collaborative network among agents. Nevertheless, it grapples with challenges such as a limited user base, the growing trend towards standardization of agent communication protocols, a lack of exclusive interaction channels, and vulnerability to restrictions imposed by channel providers. Its trust barrier primarily hinges on linear switching costs, which struggle to compete with the distribution advantages enjoyed by industry giants. If this model were to be introduced domestically, considering the high concentration of communication, payment, and social networks within super apps, the survival space for independent agent startups would be even more constrained. Instinct's product culture, centered on restraint, is challenging to replicate but also faces a contradiction between commercialization commissions and its foundational philosophy. Its $10 billion valuation primarily reflects the category option value spurred by the boom in the personal agent sector, with the core challenge being whether the pace of trust accumulation can surpass the distribution speed of industry giants.
