Any reason why you picked these altcoins in particular? My recommendation is:

• STRATIS: made to be easily adapted for big corporations, solid dev team and a exciting new update coming up this month --> breeze
• SIA: cloud storage for a low price (very nice idea), although I dont see the price going x10000 with the current marketcap.
• Golem: sell your cpu/gpu. Many big and small businesses could use this service, if it keeps being cheap to use the service :)

anyway, just my 2 cents here, Cheers
