Wickr is an American software company based in San Francisco.[1] The company is best known for its instant messenger application of the same name.

The Wickr instant messaging app allows users to exchange end-to-end encrypted and content-expiring messages, including photos, videos, and file attachments.[2] The software is available for the iOS, Android, Mac, Windows, and Linux operating systems.


Wickr was founded in 2012 by a group of security experts and privacy advocates.[2] Nico Sell served as the company's CEO until May 2015 when she became the co-chairman of Wickr and CEO of Wickr Foundation, the newly launched nonprofit whose seed funding was provided by the company.[3] Mark Fields, who previously led CME's Strategic Investment Group, became the company’s CEO.[4]

Initially unveiled on iOS and later on Android, the Wickr app allows users to set an expiration time for their encrypted communications.[5] In December 2014, Wickr released a desktop version of its secure communications platform. The release of the desktop Wickr app coincided with introducing the ability to sync messages across multiple devices, including mobile phones, tablets, and computers.[6]

All communications on Wickr are encrypted locally on each device with a new key generated for each new message, meaning that no one except Wickr users have the keys to decipher their content. In addition to encrypting user data and conversations, Wickr strips metadata from all content transmitted through the network.[7]

Since its launch, Wickr has gone through regular security audits by prominent information security organizations, which verified Wickr's code, security and policies.[8] Wickr has also launched a "bug bounty program" that offers a reward to hackers who can find a vulnerability in the app.[9]

As of January 5, 2015, Wickr has a score of 5 out of 7 points on the Electronic Frontier Foundation's secure messaging scorecard.[10] It has received points for having communications encrypted in transit, having communications encrypted with keys the provider doesn't have access to (end-to-end encryption), making it possible for users to independently verify their correspondent's identities, having past communications secure if the keys are stolen (forward secrecy), and having completed a recent independent security audit. It is missing points because its code is not open to independent review (open source), and because its security design is not well-documented.[10]


In March 2014, Wickr announced its Series A funding round of $9 million led by Gilman Louie of Alsop Louie Partners. The series also included investments from Juniper Networks and the Knight Foundation.[11]

In June 2014, Wickr announced its Series B funding round of $30 million led by Breyer Capital, including CME Group and Wargaming.[12]
