Sierra’s Bret Taylor says the era of clicking buttons is over

Sierra, the enterprise AI agent startup co-founded by former Salesforce co-CEO Bret Taylor, is pushing a vision where natural language replaces traditional software interfaces. At the HumanX conference, Taylor argued that the era of clicking through complex applications like Workday is ending. Instead, Sierra's new tool, Ghostwriter, allows users to describe a task in plain English, prompting it to autonomously create and deploy a specialized AI agent to execute it. The company, valued at $10 billion after a $350M funding round last September, has already reached a $100 million annual revenue run rate and demonstrated this speed by implementing an agent for retailer Nordstrom in just four weeks.

Taylor's core thesis is that companies want solutions, not software, and that infrequently used enterprise tools are prime for replacement by conversational AI. However, the article notes a significant gap between this vision and current reality. Technologists and investors point out that AI agent implementation is far from fully autonomous. Companies like Sierra and legal AI startup Harvey still rely on 'forward-deployed' engineers to constantly update and fine-tune customer agents, indicating that the promised hands-off, language-driven future requires substantial human oversight and maintenance behind the scenes.
