In the short few months we've been up, we've had confirmation from a large number of companies having successfully filled vacancies via our site. That alone is justification to get it up and live. Also it's the best way of testing what works and what doesn't and more importantly, getting feedback on what users like and what they don't.
Would it not be more useful to launch with at least some of the innovative features you've hinted at?
If they were complete, they'd be live! The process we follow is to launch an MVP and iterate often. As we get a feature to a usable level, we'll update.
What value are you adding to direct employers or job seekers?
At the moment there are few publicly known job sites in the UK that contain zero recruiter vacancies. As a minimum, we provide that alternative right now with the promise of a lot more to come.
