Sierra AI has raised $500 million at a $7 billion valuation to build personal AI agents that can manage email, schedule meetings, pay bills, shop online, and handle customer service calls on your behalf.
What Sierra's Agent Can Do
- Manage email: auto-respond, categorize, unsubscribe
- Schedule: coordinate meetings across time zones
- Shop: find best prices, apply coupons, track deliveries
- Finance: pay bills, dispute charges, negotiate rates
- Customer service: sit on hold and resolve issues for you
Privacy Architecture
Sierra runs AI agents locally on-device where possible and uses encrypted enclaves for cloud processing. Users can view a complete log of every action their agent takes and revoke access to any service instantly.
