Sublime Raises $9.8M to Build Out Email Security Platform

By Hua Wang & Michaela Althouse

The startup has been operating behind the scenes for a year in private beta, with several big-name customers that include Spotify. Sublime built an open email security platform, which allows any user to write, run or share rules in a universal domain-specific language to help block email attacks. The round was led by Decibel Partners and Slow Ventures, with additional participation from founders and security operators.

“The traditional black box approach to email security fails to take advantage of the expertise and context that security professionals have,” CEO and founder Josh Kamdjou wrote in a post announcing the company. “Sublime lets defenders protect their organizations without one hand tied behind their backs.”
