This is awesome. I've recommended HelloFax dozens of times in the past year and a half or so for the awesome collaborative signing flow, and only a handful of time for the fax - though it's a lifesaver when I need to fax things. The more widespread adoption electronic signatures get, the more convenient life will be in general. And more secure too - we've obviously understood secure digital signatures for awhile, but the cultural shift has just taken forever to move online. I'd be curious to hear from the founders if there are plans around expanding the scope/security of signatures, and some of the worries around mutually-compatible implementations?
