Sublime: AI-Based Email Security Company Raises $60 Million (Series B)

By Amit Chowdhry • Yesterday at 7:25 AM

Sublime Security – an AI-based email security platform – announced it had raised $60 million in Series B funding, bringing the company’s total funding to $93.8 million. The current funding round was led by IVP, with participation from new investor Citi Ventures and existing investors Index Ventures, Decibel Partners, and Slow Ventures. The latest funding round will support continued investment in Sublime’s platform and community.

Sublime Security also welcomed Colin Jones as President to run go-to-market. Jones was most recently Chief Revenue Officer at Wiz, leading go-to-market and driving company growth from $0 to $250 million in revenue.

Since raising its Series A earlier this year, Sublime has quadrupled its customer base, adding trusted enterprise companies such as Elastic, Benteler, and Cribl to its impressive list of existing customers, including Spotify, Reddit, Brex, and others.

The funding round comes as generative AI (GenAI) has made it easier and more cost-effective for threat actors to send highly targeted and varied attacks in high volumes.

The Sublime platform offers comprehensive protection from email-originated attacks and can adapt to evolving threats without additional work from security teams. It aims to transform email security in the same way CrowdStrike and Endpoint Detection and Response (EDR) revolutionized endpoint security, delivering comprehensive coverage with unmatched visibility and control.

Sublime offers a new approach, utilizing an AI-powered detection engine to achieve higher efficacy and minimize missed attacks that can adapt in minutes or hours as threats evolve. And the platform protects organizations against even the most advanced email-borne attacks, breaking away from the limitations of traditional black-box solutions.

KEY QUOTES:

“Email is the backbone of business communication but remains an outsized cybersecurity risk. Sublime not only gives security teams an effective and easy-to-use platform but also a transparent and configurable product. As the age of AI shifts the landscape, CISOs are looking to Sublime for an email security solution that can keep up.”

  • Cack Wilhelm, General Partner at IVP

“GenAI has radically changed the email security problem and yesterday’s solutions can’t solve the challenges of today and tomorrow. The future of email security lies in the flexibility to address new techniques from attackers and solve the real problems security teams see everyday with email. We’re thrilled this new funding will accelerate our mission to make email safer for everyone.”
