More than a Job Board

So, my biggest gripe with hiring/job boards at the moment is that they all advertise title, salary, location, and role. They tell you WHAT the job is. Soooommmeettimess they'll tell you the day to day, and more about the company dynamic (the HOW). But no site seems to tell you WHY the company exists (what problem they're solving), WHY the job exists (what pivotal role you'll play in solving that problem), and WHY you should apply (apply if you love X, care about Y, want to make Z happen, etc.). I actually want to start a company around the above, so your idea could fit into it? (I'll also make this its own dedicated posting on HBBI, just for more traction)
