It certainly sounds like they have everything (business case /tech etc) well laid out. If I were a potential employee I'd have liked some information on what kind of equity a new employee could expect - RethinkDB set the standard here (http://www.rethinkdb.com/jobs/), but other than that very very minor quibble i think this is as good a recruiting pitch as I have seen.
(Due Disclosure: (a) Amit Rathore is a good friend of mine. (b) I have nothing to do with Runa or this ad. I am just curious as to how people here perceive the opportunity).
