I've been tracking these guys since they launched. I spoke with them about the possibility of getting funded, early on in their launch, for expansion.
Long story short, it boils down to: give us $5K or $10K, and we'll put you in contact with money people. After 43 years, by BS filter is pretty good, and it was flashing Bright Red.
So I took a sit back and watch approach. The industry desperately needs something like this. Not only for development funding, like the non-adult world has, but also to give it another shield of protection from being crushed. Much like the hotel industry, if all the hotels offer adult in room, it's difficult to crush that business. Big money (and many religious backers) are backing those hotels.
If we can have enough "legit" mutual fund backing, it will be tough for the religious right to get a leg up on witch hunting.
So I've been waiting for more than 2 years now for the story of "Wow! I used adultvest to build my adult business, and now I'm fat and giggly!"
................still waiting.
