Inkbox is the identity and communication layer for AI agents. With one API, an agent gets its own email inbox, a phone number that can call and text, iMessage, a persistent internet address for webhooks, and an encrypted credential vault with TOTP/2FA - so agents can sign up for services, receive confirmation codes, and act on context that flows across every channel. Founded in 2025 and part of Y Combinator's Summer 2026 batch, Inkbox is built by a team of MIT and Harvard-trained researchers.

Zatanna is a Y Combinator W26 startup that turns software into agent-first APIs. Most AI agents are stuck navigating clunky UIs to interact with systems that never built a proper API - Zatanna fixes that by observing a workflow once, reverse-engineering the underlying HTTP request sequence, and serving it as a clean, reliable endpoint. No browser scripts, no screen-scraping fragility: just fast, production-grade API access to legacy ERPs, insurance portals, marketplaces, and any operational software your agents need to talk to.
