GoKawiilYC-backed Alter launches access control platform for multi-user AI agents
Alter, a startup from Y Combinator's Summer 2025 batch, has launched a product that manages credentials and permissions for AI agents acting on behalf of multiple users. The system stores credentials in a central vault and injects them into proxied API calls at request time, while assigning each agent its own identity and scoped permissions. Sensitive actions, such as a billing agent issuing refunds, can be configured to require human approval before executing.
