Sublime Security

We’re excited to announce that Sublime has raised $150M in a Series C led by @Georgian_io, joined by new investors @Avenir_Growth, @01Advisors, @jonoberheide, and @nicoleperlroth, and existing investors @IndexVentures, @IVP, @slow, and @CitiVentures. This year we launched ASA and ADÉ, our AI agents that autonomously triage threats and auto-adapt coverage, freeing security teams from repetitive work and delivering rapid, tailored defenses. We’ve grown our customer base 4x since the beginning of the year while maintaining zero enterprise customer churn since company inception. This funding accelerates our vision to deliver autonomous email security that adapts to each organization's unique needs, stopping sophisticated attacks while eliminating the manual work and vendor bottlenecks of legacy solutions. Thank you to our customers, partners, and investors for being on this journey with us. 🔗 Read more: sublime.security/blog/sublime-r…
