About Colloid, LLC

Colloid, LLC was founded in 2011 by Joe Chiarella and Greg Mosher as an intellectual property development company. Greg and Joe worked very well together at their last company: Exploit Prevention Labs, Inc. which was sold to AVG Technologies in late 2007. They enjoyed the collaboration so much that they thought they’d do it again.


The first technology to emerge from Colloid is the UberCrypt Framework. Soon, the cloud service, KeyRepository, will launch. Stay tuned for more…
