A very rare L's clearance plant? Sounds unlikely unless that's just not true about it being rare. Your plants look like they could be from cactuscollection.com, which has unleashed a ton of tiny succulents on BBS's lately. Their website has a ton of pics. I'd check the Graptoveria, Graptosedum, Sedeveria, as well as Sedum. May be easier to ID after it gets more sun (correct color) and a more mature look and/or, of course, flowers.
