I am working on http://contactsanalytics.com/ I call it "Google for email" why? You can build your email list depending on niche you want to target. Check it out. Why I made this? I think that marketing field is really challanging and I think that "big data" thing is really exciting nowadays.
Neat project. I poked around a bit and had a few pieces of feedback.
- I like the full disclosure aspect. If I weren't comfortable in a whole copy-paste, being able to get an easy list to evaluate sources myself would still be handy.
- I think your algorithm is scanning too deeply including comments sections. It found an email address from a username of a commenter in a Disqus thread on my own personal blog site
- It seems that if you were to search by company name you can get a lot of results of people who just mention that company on their own blog
- Tiny typo I saw in the last sentence of "how it works": "this way you can check if this is a good contact or not."
