I had success with pitching to consultancies. They have the right contacts and are probably interested in re-selling your cool and innovative product. Contact details of the right managers are usually published on their website because they want new customers to call them (but no one is stopping you to contact them for pitching :)).

In general I've realized over the years that you are much better off if you can somehow get the customer to come to you, asking for your product or service (vs trying to "sell" to them). Of course easier said than done, but this is the essence of marketing -- perhaps make some noise in the right places so interested customers become aware of you.
