Caleb Sima — Co-Founder

With over 25 years of experience in cybersecurity, I am passionate about building and investing in innovative solutions that protect enterprises. I have co-founded and led two security startups, Bluebox and SPI Dynamics, that were acquired by Lookout and HP respectively, and served as an EIR at Andreessen Horowitz, one of the most prestigious venture capital firms in Silicon Valley. Most recently, I was the Chief Security Officer at Robinhood, the leading online brokerage platform that democratizes finance for all. There, I oversaw the security strategy, operations, and IT for the company, ensuring the highest standards. I also helped Robinhood scale its security capabilities and culture as it grew from a $5.6 billion valuation to a $40 billion IPO. Additionally, I was a board member at Cobalt.io, a cloud-based security platform that connects organizations with ethical hackers, and an advisor and investor to several security startups and nonprofits. My mission is to make the web a safer and more secure place for everyone.
