Interesting, but the website still does the usual thing of pushing people to the sign-up page without giving much information. If you're pitch is "we are aggressively honest" then an an indication of the jobs available seems like a good idea. Established recruitment firms list them all. I know it's tough establishing a two sided market, but it leaves a bad taste in my mouth when companies waste my time by inviting me…
No, they don't. In fact, the opposite is usually true: established recruiting firms will keep the company name pretty quiet, and only reveal it on outreach to specific candidates.
Just because someone doesn't list that kind of information on the homepage does not automatically mean "dishonest". It's very common for "allow my company's name to appear on your website" to be a negotiated item in a partnership contract. Getting it approved can require involving people all the way up to the CEO. The juice often isn't worth the squeeze, and the companies you can get to agree to it are the ones you least care about putting on the website anyway.
Particularly for recruiting agencies working on contingency, I can easily see why clients wouldn't want their partners to plaster their open reqs + brand on the front page of the website.
