As a foundry, you can download your own fonts free of charge on MyFonts. Simply sign in to MyFonts using the account associated with your foundry. Add any fonts you’d like to download to your cart. On the Payments screen, please select: 'No charge for fonts from your own foundry'.
To get your webfont files, simply add webfont licensing to your cart. After checkout, you'll see what the customer sees and can create your webfont kit there.
You can also download the font files from inside Foundry Platform by clicking the font family in the "Released Families" section, and using the download icon on the right.
