I would recommend trying to contact Matt Cutts and see if he can point you in the right direction. Not to sound discouraging though, I am sure that Google gets hundreds of calls a month from small companies with products that the companies feel Google should either buy or do business with. As such, you may be climbing a very steep hill here. If you truly believe your products offer value to the Google platform, I would recommend building some PR buzz around the products first. Since Google is developing something similar it validates your product and with some clever marketing skills you should be able to get some of the bigger blogs to at least evaluate your product. My plan would be to make Google come to me instead of trying to get into Google. I think your chances are better of getting them to come to you, especially if you already have an active and growing user base.
