Pre-Product Funding

Is there anyone here who has raised funds for a pre-product? What was your impression of the situation? I'm stuck, but I'm not giving up (and I'm not going to) - I've been working on an idea (I'm a UX guy), and now I'm looking for investors who are interested in individuals like me. If any of you can offer any suggestions, I would be grateful. I'm seeking a technical co-founder as well.
