Product — Argo
Argo is an AI agent company that remembers everything. Solo founders and small teams lose hours re-explaining context to AI tools; Argo gives them a crew of specialist agents that share one long-term memory, kept as plain files the user owns, so one person can operate like a well-organized company. Argo is local-first and built on the Claude Agent SDK. Each user connects their own Anthropic account through Anthropic's official sign-in or their own API key; we never resell or intermediate model usage.
Enterprise AX
We help Korean companies with AI transformation: diagnosing repetitive work, designing AI agent teams and harnesses, building them into daily operations, and coaching teams to run them. See Enterprise.
