There was (and still is)a project called Bigloo (https://en.wikipedia.org/wiki/Bigloo) that was interesting by allowing to get C, JVM and .Net code from scheme programs. We were a Scheme shop and experimented a lot with MzScheme (our main implementation, Bigloo and Kawa)
P.S. regarding success stories for Scheme - we had a commercial product written in it, quite successful. I wrote the article about it in Russian - should be ok to read via google translate: https://translate.google.com/translate?sl=auto&tl=en&u=http:...
Oh yeah, Bigloo was also on my list of promising Schemes, and I tested with it.
At the time, Bigloo looked like one of those projects that seemed to have a lot of energy, and didn't seem to be as well-known on my side of the pond as it should be.
(Another time I experienced a kind of geopolitical diversity: I was working with a Web-native language, Curl, which started in the US, but took off with some industry in Japan, never in the US. I suppose that "tech" not being fully homogenized is a very good thing, but we do very often have the situation of some group A missing out on goodness that B has discovered, and vice versa. I think is just another reason to embrace diversity in general, to learn and benefit from goodness others have found, while also letting that diversity machine keep finding new goodness in parallel.)
