Some low cap's i'm either invested in myself or plan to invest in in the near future:
Axpire, NapoleonX, OriginTrail, Ambrosus, Block Array, Devery.  Most of them, well basically all but NPX, are b2b solutions which i think/hope have a higher chance of succes.  TRAC/AMB/ARY will also have staking or MN possibilities if that's something you're interested in.
