If you're curious what it was, it's here: https://codano.com/typeforge/.
The reasons I've probably done poorly:
1) I haven't spent time networking with the people who are the market of the product. I worked with a few people on /r/gamedev on it last year, but never followed up.
2) There's a lot of other tools in this space, some free, some not-free (but platform-limited) and I haven't distinguished myself from any of those.
3) There's not a lot of supplemental material to suggest how people might use the product and why people might want to use this product over any others.
EDIT: and if you want a free license for kicks, just email me (see my profile).
