Alter获Y Combinator孵化，为多用户AI代理提供访问控制服务

由Srikar和Kevan创办的初创公司Alter获得Y Combinator S25孵化资格1。该公司为能代表多个用户采取行动的AI代理提供访问控制和凭证管理服务1。

Alter的核心产品通过代理层管理下游API凭证，在每个API请求层面考虑最终用户身份，执行细粒度运行时策略和合规审计日志记录1。这一方案旨在解决规范行业中构建安全多租户代理所面临的难题1。在商业模式上，Alter提供免费层支持10000个请求，超出部分采用使用量计费1。

创始人方面，Srikar曾在高盛工作，Kevan是二次创业者，之前从事数据库初创企业1。目前Alter已与多家初创公司和防务承包商建立合作关系。多家初创公司将其用于SRE代理，Quickbooks和Rippling工资单平台已集成该产品；一家防务承包商将其应用于空气隔离代理场景1。

Alter, a startup incubated through Y Combinator's S25 batch, has introduced an access control and credential management service designed for AI agents operating on behalf of multiple users 1. The platform addresses a critical security challenge in regulated industries by managing downstream API credentials at the agent layer, enforcing granular runtime policies, and maintaining compliance audit logs 1.

The company was founded by Srikar, who previously worked at Goldman Sachs, and Kevan, a repeat entrepreneur with experience in database startups 1. Alter has already attracted customers across multiple sectors, including startups using the platform for SRE agents, integration with payroll platforms such as QuickBooks and Rippling, and a defense contractor deploying it for air-gapped agents 1. The service operates on a freemium model, offering a free tier supporting 10,000 requests, with usage-based pricing for additional volume 1.
