They're "out of stealth mode" but still tell me nothing about their product and only have an Unbounce landing page.
Basically still in stealth mode to me.
You're right -- we're still in stealth mode. The Unbounce page was a quick (and very convenient!) solution to being unexpectedly outed a few weeks ago. We're on the verge of our first release to users in a few weeks, so we'll get more information onto the landing page soon.
