Right now, we're not that different from our competitors - but we will be. Our capture system doesn't rely on video encoding, or Java plugins, or installing Javascript on a site. This allows our test recorder to be much more flexible than our competitors. We're also building a webcam capture feature - something that de-facto in traditional usability testing but so many remote usability testing solution overlook.
At the minute we just want to get something out there (our current motto is 'Minimum Viable Product') - want to get users on-board and then use the feedback to build in features.
We do want to offer access to testers, like you mentioned. This idea we're currently calling 'Business B' (we will think of a better name) and we're looking to start developing this soon after launch. Similar to usertesting.com but we think the value will be having access to a pool of testers across demographics - hopefully giving greater insight into your usability issues from people who will actually use your site.
We've got a load of big plans - this is just the start of it all.
