A word of caution - one of my former companies had a vendor do some work for them that involved disclosing the email addresses and titles for everyone. That vendor dropped it into Jigsaw and screwed up just about all of the information, so do at least some research on Google or LinkedIn to confirm that the person does still work for the company. I think I am still in Jigsaw as working for that company, too, so unless you are updating your own information in Jigsaw it won't track your job changes.
