I apologize, but as of my last knowledge update in September I don't have specific information about the content or details of the URL "ledger.com/start" or any developments related to it that may have occurred www.ledger.com/start after that time. If this is a new website or platform that has emerged since then, I would recommend visiting the URL directly or searching for up-to-date information online to learn more about it. If you have any other questions or topics you'd like me to help you with, please feel free to ask!
