# Ellelion > You build. Our AI agents do the rest. Twelve AI agents across the path from first idea through launch, growth, and support. Formed in Wyoming. Ellelion LLC (Wyoming, USA) builds twelve AI agents for developers who ship with coding agents, and for people who never write code. Each product is a separate agent. Pick one, or several. 4 products are live: Skillselion, Agent Plugins Directory, botteams.io, and Launchelion. Skillselion and Launchelion publish MCP servers a coding agent can call. Agent Plugins Directory and botteams.io are live in the browser without a public MCP server yet. Upcoming products add a server as they launch. botteams.io is open source. Skillselion, Agent Plugins Directory, and Launchelion are hosted directories, free to use. Upcoming products are planned as open source when they launch. Repositories open as each product launches. We run Ellelion products on Ellelion sites first.
