Robinhood Taps Caleb Sima to Lead Security

Caleb Sima to Join Robinhood as Chief Security Officer

Veteran cybersecurity practitioner, entrepreneur and executive Caleb Sima has been tapped to lead security at mobile stock trading startup Robinhood.

Sima, a security leader with an established presence in cybersecurity for more than two decades, announced the move on LinkedIn. He will be joining investing firm Robinhood as Chief Security Officer (CSO).

Sima was most recently VP of Security at Databricks and, before that, he managed security engineering, architecture, red team and vulnerability management at Capital One.

In the early 2000s, Sima co-founded application security startup SPI Dynamics and sold it to HP.  He also co-founded Bluebox Security, a mobile security play that was acquired by Lookout in 2016.

Sima joins the embattled financial services firm RobinHood at a sensitive time, with the company facing massive mainstream media attention. The Menlo Park., Calif-based company claims that about 13 million users trade stock and ETFs on its mobile app. 

The news of Sima’s hiring comes on the same day Reddit announced it had snagged Bank of America security executive Allison Miller to be its Chief Information Security Officer (CISO).

In other CISO-related people news, Cisco has promoted Anthony Grieco to the CISO slot following the departure of Mike Hanley.

Akamai’s Andy Ellis is also leaving the CSO role there after a 20-year career.
