I saw this from an Econontimes post that Proof was mentioned in. "...an open-source software company that develops blockchain-powered investment market platforms, has raised over $1.7M during its token pre-sale. The amount raised includes 884 ETH (equivalent to $260,000 USD) contributed by TaaS (Tokens-as-a-Service)." How did you guys get in contact with TaaS so they would invest so much into your ICO? I invested in TaaS ICO and they have been doing pretty good. So, I am guessing they saw a lot of value in Proof for them to invest $260K in your project.
For anyone interested in seeing the article I am talking about, here is the link.
