I'm the founder of <a href="http://pricify.com" rel="nofollow">http://pricify.com</a> and we've had several iterations of the product and focusing on various experiments. Currently we land users on a landing page and thats a test we've been running for a while, but we've also had it where products are listed upfront with infinite scroll. Both seem to achieve hit different goals.<p>We've spent a long time establishing landing page messages so it makes sense to users as soon as they get there - otherwise they just bounce, including HN users! I've not signed up to try this out, but there is just not enough info before asking a visitor to sign up. So may want to add some info there on the value prop?
