Some font foundries permit you to license a web font from them and then use Typekit to host the font. This "bring your own license" option is available from:
* Currently, you can only license the Web FontFonts from FontShop for use in Typekit. Other web fonts from FontShop cannot be hosted from Typekit.
Once you’ve licensed a web font from the foundry, you’ll receive a link to add it to your Typekit account. Your new font will be instantly transferred to your account and will appear under a new tab called “Purchased Fonts” in the browse fonts section of the Typekit website.
You can then use it just like any other font on Typekit: simply add it to your kit, assign it some selectors, and publish your kit. The font will work in all the browsers and devices that Typekit supports.
