Funding: Go in browsers Chromium and Firefox

What would do you if you have a technology that allows run Go in browsers Chromium and Firefox? I've finished the initial development and it works like a charm. In addition, there is also a translation compiler from Go (a sub-set) to JavaScript which is about 70% of to be finished. But there is also to build a library to handle DOM in Go. Would you ask for funding to some big internet company or go diretly to angel investors? Google: discarded because they've Dart and NaCl. Microsoft and Apple: they would be my last option because I doubt that they accept that the technology remains free source. Yahoo: they are not into a good moment, but this technology could be a help. Facebook: maybe For what I need funding? To finish the development but mainly for marketing.
