Zatanna converts legacy software workflows that lack APIs into stable, callable endpoints for AI agents. Part of YC W2026, it was founded by Rithvik Vanga (CEO, ex-Coinbase), Alex Blackwell (CTO, reverse engineering expert), and Tarun Vedula (COO). Rather than using brittle browser automation or RPA-style screen scraping, Zatanna observes a human executing a workflow once, reconstructs the underlying HTTP request sequence (including session management, cookies, TLS fingerprinting, and re-authentication), and hosts it as a clean REST API.
One platform for routing, observability, tracing, and evals across every LLM provider.
