Tianjie Jack

Tianjie Jack is a ZhenFund investor and guest in Agent 元年第 500 天：什么在消失，什么在诞生——为什么我们不该再投资 GUI 思维的软件？. He explains the thesis that investors should avoid “GUI thinking” software, meaning products whose core imagination remains bounded by screens and manual human operation.

Position In The Episode

• Argues that model capability improved faster than expected, while agent productization remained weaker than expected.
• Clarifies that the Headless Software thesis is not anti-GUI; GUI remains important for trust, review, and human communication.
• Uses a Gmail and Codex workflow to show how an agent can access a product’s underlying data while bypassing much of the traditional GUI.
• Frames Agentic Economy as infrastructure for future agent-to-agent or agent-to-service value exchange.
• Introduces Token Grant and Youyou Agent as early experiments around agent-native creation.
