What is Asteroid?
Asteroid is an AI browser and desktop automation platform. Its agents log into systems that lack APIs, including EHRs, payer portals, government registries, and legacy Windows/Citrix applications, to handle back-office healthcare tasks such as eligibility verification, referral processing, credentialing, and patient-record extraction. As an agent learns a portal, it moves from AI-driven UI interaction to deterministic scripts and reverse-engineered API calls, returning structured JSON. The platform includes an encrypted credential vault, run recording, and human approval checkpoints, and is accessible through a developer API, MCP support, and a no-code UI.
Our verdict
Asteroid suits healthcare and insurance operations teams that need to automate portal-based, API-less workflows under compliance constraints. It's backed by YC and a March 2025 seed round, with 100+ claimed customers in that vertical. The tool is narrow and healthcare-specific rather than a general-purpose browser agent, so it has less to offer teams automating portals outside that sector.

Agentic automation tools give an LLM control of a browser to navigate, click, and fill forms toward a goal, rather than following a fixed script. They are newer and less predictable than selector-based scraping, but they handle sites and workflows that are hard to hardcode.
