I would like to fund my social startup via blockchain. I realized that most of startups here are getting funded via ICOs, they create coins and they distribute coins to investors. My app is social one like Snapchat or Vine, it doesn't require coins. Can I look for investment via blockchain without ICO and coins?

Which one is better for you when it comes to social cryptocurrencies?
I've been looking for some social cryptocurrencies because I want to invest in one, I'm all about social networks and I think those will make a boom, maybe even soon.

Reddcoin: https://www.reddcoin.com/
MimiCoin: http://hellomimic.com/ico

Are there any other social currencies?
