I agree that "Demo" does make it seem like more of an enterprise application. I got a similar feeling about "Free Demo" and, to me, it felt like it cheapened the product.

I've played around with different words and phrases, and I think matching your other buttons actually works the best. I took two screenshots, one title case and one sentence case. I like sentence case but it's inconsistent with your "Sign Up" button.
