Are you thinking of Typekit, maybe? Typecast is an app for typesetting web fonts, basically. It uses fonts from Google Fonts, Typekit, and I think a couple other webfont providers. It's not in competition with webfont providers at all. Although, now that it's been acquired by one, that may change.
Even though we've been acquired by Monotype (the company behind fonts.com), Typecast will continue to offer web fonts from a range of providers.
We think that designers should be able to experiment with the best type available on the web and that belief doesn't change now that we're part of a bigger company.
