they are one of the seven winners of the recent seedcamp 2008 round. seeing the recent develpments of former seedcamp finalist zemanta, this can be a worthy boost of soup.io's development.
just to give an idea how, look at zemanta. they just secured another investmet from union square ventures, also involved in twitter, del.icio.us, feedburner, and the like.
this supports the thesis, that pitching can help progressing a start.up a lot, as already discussed here.
Update: And even if not all agree, winners are winners!
