Turns legacy software workflows into agent-first APIs by observing human actions, reconstructing the underlying request flow, and exposing stable endpoints for AI agents and internal systems.
Publicly, Zatanna is focused on turning human-only workflows into reliable APIs for AI agents, with emphasis on session handling, auth, retries, request sequencing, proxies, TLS fingerprinting, and anti-bot resilience. The likely near-term roadmap is a more self-serve workflow capture product, deeper observability, reusable integration templates, and enterprise controls for sensitive environments.
Private and non-traditional signals suggest the team started from vertical AI pain points and pivoted down the stack into infrastructure. Founder backgrounds and messaging point to strong anti-bot and workflow reverse-engineering capability. The absence of broad public hiring suggests a tight founder-led technical team, while customer/logo and throughput claims imply high-touch deployments with strong pressure toward productization. CEO Rithvik Vanga's background includes Coinbase, Series, Hamming AI, and John Deere with a University of Michigan CS degree.
Uses ML to infer the hidden structure of legacy software workflows from a demonstrated task and convert that behavior into a stable, agent-usable API.
Instead of making an AI click around a website forever, it learns the important steps once and turns them into a clean machine-readable action.
This is like watching someone navigate a chaotic government office once, then drawing a secret back-door map so everyone else can skip the waiting room forever.
Uses ML-assisted detection and adaptation to keep workflow-backed APIs reliable when upstream software changes, fails, or triggers anti-bot defenses.
When the old software changes or breaks, the system tries to figure out what went wrong and recover instead of just failing silently.
It is like having a mechanic riding inside the car who can tell whether the problem is bad gas, a dead battery, or a closed road, then reroute before the trip is ruined.
Uses ML to translate messy outputs from legacy systems into clean structured responses and agent-compatible tool interfaces.
It turns confusing screens and software responses into neat, standardized answers an AI agent can actually use.
It is like hiring a translator who not only speaks every messy software dialect, but rewrites each answer into the same clean memo format your whole team can use.
Zatanna's edge is a combination of anti-bot know-how (Alex Blackwell previously at Pikkit bypassing anti-bots), workflow reverse engineering, and a thesis that the real bottleneck for agents is software access rather than model intelligence alone. Rithvik Vanga brings experience from Coinbase, Hamming AI, and John Deere (University of Michigan CS).
