FullContact provides APIs to support individuals, businesses, and developers in managing and enhancing their contact and customer data. The APIs can be used to provide social profiles in an app, improve contacts in address books, enrich CRM information, or create highly personalized marketing campaigns.
It imports data found on the internet (such as social media profile URLs, web addresses, etc.) to your contact database. The app actually uses humans to import data from your business cards using a snapshot (and does so accurately). It allows you to download a backup of your contact database that can be uploaded to your email client. FullContact integrates with Google a.ccounts, Twitter, LinkedIn, Yahoo, and more. It also provides a good format for importing contact databases using Excel. However, customer service is a bit slow
This is my new favorite app for organizing contacts and segmenting email lists. It is also the only app I have used that will transcribe business cards with 100% accuracy (they use humans to enter info from pictures of cards rather than software, like most other apps). The "merge contact" feature is great and allows you to review the contacts being merged before doing so automatically. It also integrates with Google accounts, LinkedIn, Twitter, and Yahoo. Another great feature is the ability to export data in a file, which you can then upload to your regular CRM software or to Constant Contact. I wish it would allow for more business card uploads per month. Even the paid subscription has a limit of 50 cards per month. I contacted customer support to inquire about increasing this limit and was told that I would need to upgrade to a yearly contract in order to do so. If FullContact continues to be useful, I will likely upgrade. However, given that the business card contacts is one of this software's best features, I was disappointed that this allowance could not be increased. Overall, however, I would highly recommend FullContact
Radicale is a Linux-based contact server that works well with many platforms. It is not the most user-friendly, but if you know your way around creating virtual servers and putting them in the cloud this could be a great free solution for you. The best part is you can have read-only contacts!
