How do I get in touch with investors/funds with just an idea and no product?
There are many wonderful ideas, and they are not necessarily easy to come up with. So congratulations on having thought of one!
However…
“Having value” and “Being fundable” are two completely different things. What the more experienced responders here are saying is completely accurate: while a good idea is usually a necessary ingredient for the formation of a good company, it is not sufficient by itself for any serious investor to fund.
Why? Because there are also other good ideas out there, some of which have already been developed, tested and put into practice, thus decreasing the amount of risk an investor will be taking. The bottom line is that ideas by themselves are simply not fundable by professional investors (although, as a couple of other answers have suggested, you may be able to raise some initial money from your friends or family members.)
