# Brian Silverstein

> Brian Silverstein is the founder and CEO of MirrorTab, a San Francisco cybersecurity company that treats the browser as the new battleground and tries to take it off the table entirely. Using server-side isolation, MirrorTab strips the client-side attack surface so malware, malicious extensions, and bots never touch the real code, data, or APIs behind a web session. Before MirrorTab he was an early co-founder and CTO of Honey, the shopping-rewards browser extension acquired by PayPal, and an engineer at Apple, Nest, Broadcom, and Freescale. A Cornell-trained electrical engineer with eight patents, he raised an $8.5M seed in 2025 led by Valley Capital Partners with GV and others.
