Eric Eyken-Sluyters, a Salesforce executive who oversaw Agentforce, the company’s flagship AI agent product, has left after 23 years to become president of field operations at Sierra, the AI customer service startup founded by OpenAI chair and former Salesforce co-CEO Bret Taylor. Sierra, valued at $10 billion as of late 2025, builds AI agents that compete directly with Agentforce and has been actively poaching Salesforce customers, making the hire a pointed competitive move. The departure comes as Salesforce shares have dropped nearly 30% in 2026 amid investor concern about AI disruption to its core business.
