In simple English
This tool helps startup founders keep track of who owns shares in their company. It replaces expensive commercial tracking services with a self-hosted option. You can record funding rounds, share legal documents, and send updates to investors. It is free to run on your own server, but you will need technical skills to set it up. Maintenance falls entirely on you once it is running.
