The Santa Monica-based TigerText secure messaging app developer has raised $50 million in a new round of Series C funding. To date the company has accrued $81.1 million since its founding in 2010.

TigerText is an app for mobile phones, Apple Watches and for desktop computers which allows health care professionals to text medical information concerning their patients without violating privacy laws. The app accomplishes this using such features as self-destructing messages, message recall and secure file transfer.

“We are opening up and allowing third parties to take the (software development kits) for iOS, Android and JavaScript and we allow them to drop those into their own applications, so they have secure messaging,” said Chief Executive Brad Brooks. “There’s a lot of need for messaging in general and in particular there is a lot of need for secure messaging.”

TigerText is not only a solution for medical professionals controlling privacy while sharing information. Several financial companies have also purchased the messaging software in order to comply with finance industry rules regulating privacy, including those stipulated by Sarbanes-Oxley.

The company plans to use a portion of its new funding to market TigerText to new users through expansion of advertising. The money will also be used to improve TigerText software. Dr. Robert Mittendorff, a principal at Norwest Venture Partners, was also named as a new member of the board of directors as part of the funding round.
