Santa Monica enterprise messaging app TigerText announced Tuesday that it named three new members to its board representing its latest investors.

Joining the board are Sean Flynn, partner at Shasta Ventures; Steve Yecies, venture partner at OrbiMed and Vijay Lathi, managing director at New Leaf Ventures.

The three firms they represent participated in a $21 million Series B fundraising round in January.

In addition to the investment funds named above, Reed Elsevier Ventures, Telus Corp., Easton Capital and New Science Ventures participated in the Series B round.

The company has raised a total of $31 million to date.

Brad Brooks, co-founder and chief executive of TigerText, said the three men “bring a wealth of startup expertise.”

When TigerText was founded in 2010 it sold a consumer app for sending text messages with a built-in self-destruct feature. Now, the company pitches itself as a secure messaging service. The app is compliant with privacy regulations and has been used by a number of heath care organizations.

TigerText announced in February that it would reimburse customers for up to $1 million should they be hit with fines resulting from privacy violations under the Health Insurance Portability and Accountability Act that occur while sending and receiving confidential health information via the app.
