If you're targeting a vertical, using one example customer, lookup who bids against them for the same keywords in Adwords on SEMRush. Adgooroo and Spyfu also support this.
If you're selling a horizontal product targeting customers where their existing technology they use could tip you off (e.g. companies that use Marketo and Mailchimp), LeadLander and BuiltWith are useful.
Once you get a list of target companies, the next trick is finding the right person to sell into. If you know their title, search Google like this:
site:linkedin.com "Company Name" "Title"
That works well since it lets you plow past Linkedin's limitations on searches outside your personal network.
Once you figure out your customer's company, name, and title, head over to email-format.com or data.com to look up the email format for the Company. With Rapportive for Gmail, you can take a few guesses and usually find the right person. Or read this post: http://www.distilled.net/blog/miscellaneous/find-almost-anyb...
