Sublime raises Series B to... keep doing what we've been doing, but better

Sublime, a security solutions company founded in 2019, has rapidly gained popularity and recently secured $60 million in a Series B funding round led by IVP, with additional support from Citi Ventures, Index Ventures, Decibel Partners, and Slow Ventures. The company, which began with co-founders who aimed to disrupt an industry reliant on opaque, one-size-fits-all solutions, has achieved success with its transparent, customizable approach that allows customers to self-host and is free for the community. Despite skepticism, Sublime's detection engine has proven effective, demonstrated by its role in protecting the Harris campaign during the U.S. presidential election from email threats. The company has not engaged in traditional marketing efforts, relying instead on word-of-mouth endorsements due to its strong performance and customer satisfaction. As AI-assisted threats escalate, Sublime is committed to innovating in email security, focusing on real-time adaptability and transparency, while continuing to invest in threat research to enhance industry knowledge.
