Check the thread below.

It's a pretty good overview of the current running sig campaigns.

This is also my basis in looking for a signature campaign. All currently running campaign are listed, specially if you are looking which one fits to your rank status. The best guide for a Jr. Member, also consider this one as a tool.

But, we are on the marketplace (Altcoins) so I'm pretty sure that the OP is asking for signature campaigns with an altcoin/token pay. That link is for bitcoin payments only (or sometimes hybrid, paying with altcoin + btc).
@OP why not join the sirin labs on their campaign ? https://bitcointalk.org/index.php?topic=2321116.0 . They are known for making a well secured android phone and now they are targeting to adopt blockchain.
I believe it is worth of your time to join projects like this than anything out there since they have already proved their work.
