I currently have an excel spreadsheet of 15,000 contacts from business cards and linkedin. Columns include name, e-mail, industry, country, city, company, position/title at company, assistant name, assistant e-mail, etc.
I need a program to be created that can store these contacts and synchronize it with the linkedin accounts of two different users (the 15,000 contacts are a combination of two people's business contacts). This way if Mr. X changes his job on Linkedin, his contact information in this database system would automatically update as well.
Would be great if it could also pull from the web. Basically I'm looking for something like FullContact, but that is much more user friendly. I want to be ably to easily search/sort like Excel can (by country, company, industry, etc.). I also want to be able to download into an excel if needed.
Thank you for your help!
