This a16z AI podcast episode interviews Zeno Rocha, CEO of Resend, about building applications for AI agents. The discussion covers the evolving concept of "agent experience" (AX), contrasting it with developer experience (DX), and explores how to design products for seamless agent interaction. Rocha highlights the importance of minimizing friction for agents, exemplified by Resend's instant email-sending capability, and emphasizes the growing significance of the Message Composition Protocol (MCP) as a standard for agent-to-product communication. A key takeaway is the shift towards content-focused email design for agent-to-agent communication, prioritizing plain text for easier parsing by AI models. The episode concludes by discussing the future of email and AI, predicting a significant increase in agent-driven actions and the need for product redesigns to accommodate this shift.
