Moon™ is the operating system for agentic recruiting.

It is a multi-agent AI platform that automates the full recruiting lifecycle end-to-end — from sourcing to evaluation to coordination — with humans in the loop where judgment matters.

Moon evaluates and ranks thousands of technical candidates using LLM-driven assessments and a proprietary matching engine that captures deep technical, career‑progression, and role‑fit signals. It continuously enriches candidate profiles, runs autonomous sourcing campaigns, filters noise at scale, and surfaces the top 1 percent of talent for human review. Client feedback is fed directly back into the system, allowing Moon to learn and improve with every hiring decision.

The result is a recruiting co‑pilot that replaces fragmented tools and manual workflows with a single intelligent system — dramatically reducing time‑to‑hire while increasing signal quality and consistency.
