I've met the Fundable team in person, they're based in Columbus, Ohio. They're very determined to help entrepreneurs and I've seen a lot of success stories from startups raising funds on their site. Your best bet is to set up an account and give Fundable a call, they're very personable and I'd expect they'd be very honest about your startup's realistic viability in fundraising.
