Floodgate Fund participated in several projects, including crypto projects. They are based in Palo Alto, CA. I can't give you any advice because I am not sure whether they are still active or not. Judging by the information they left they are not. Nothing is being maintained now. Their own blog on the website was last updated in August 2018. Ok, let's assume they have nothing to share, it happens. Maintaining a blog is a headache. But what about the twitter profile? As far as I know, it's the only profile in popular social media they have. And it's abandoned. At least, they haven't posted anything since the end of June 2018. In this case, being picky is necessary because that's how we can understand whether it's worth contacting them or not. Probably, it will be just a waste of time.
