Real Alt Coin Businesses Seeking Investment

Lots of alt coins are being created, but not so many businesses actually supporting and using these alt coins. I feel like its the ecosystem of websites, services and businesses of all kinds which are both most needed and also most viable in terms of real long term profits at this stage.

There are also some great decentralized services these start up businesses could use to get funding, such as Counterparty, NXT, Bitshares (soon) and so on. It would be great for alts in general if more people from other coins would start businesses by getting investments through these services. To me it seems like the best way to invest in crypto would be to spend part of your money on a coin itself, and part of it on services which help that coin to succeed. That way if your investment in the business succeeds you profit from the business, but also increase the value of the coins you hold - so it kind of doubles your returns. A lot of coins have funds for marketing and business development stuff which take donations, but I think most people would prefer to make an investment and see a return rather than giving donations.

If you know any good alt coin businesses seeking investment through some kind of decentralized asset exchange please recommend them here! Ideally I'd like to hear about services supporting coins which don't have an asset exchange themselves, rather than for example NXT related projects seeking investment on NXT AE, but all recommendations are welcome.
