HiveLink

HiveLink allows you to share your Excel models while securing your formulas and protecting your Intellectual Property macros and data models ("IP"). Your IP stays with you, while HiveLink sends you the users' input and automatically sends the model results back to their spreadsheet.

Thanks to Hivelink's user manager, you control exactly who can use your spreadsheet, so if it gets copied around to other people without your permission then it is useless to them.
