Sublime Security, an AI-powered email security platform, has raised $60 million in Series B funding, bringing the company’s total funding to $93.8 million. The round was led by IVP, with participation from new investor Citi Ventures and existing investors Index Ventures, Decibel Partners, and Slow Ventures. This funding will help drive further innovation in Sublime’s platform and expand its community.

Strategic Leadership Addition

1. Colin Jones Joins as President

• Colin Jones, former Chief Revenue Officer at Wiz, has joined Sublime Security as President.
• Jones played a pivotal role in scaling Wiz from $0 to $250 million in revenue, bringing his go-to-market expertise to Sublime as the company continues to scale.

Significant Customer Growth

2. Rapid Expansion in Customer Base

• Since raising its Series A earlier in 2023, Sublime Security has quadrupled its customer base, adding prominent companies like Elastic, Benteler, and Cribl to its roster.
• Existing clients, such as Spotify, Reddit, and Brex, continue to trust Sublime to secure their email environments.

Addressing the Evolving Threat Landscape

3. The Changing Dynamics of Email Security

• The rise of generative AI has made it easier for threat actors to launch targeted, high-volume email attacks. This has changed the landscape, making traditional, one-size-fits-all security solutions obsolete.
• In 2023 alone, Business Email Compromise (BEC) led to nearly $3 billion in reported losses, with even higher unreported figures. As attackers adapt, companies need email security solutions that are adaptive and dynamic.

4. How Sublime Security Stands Out

• Sublime’s platform leverages AI-powered detection to protect against evolving email-borne attacks, with the ability to adapt quickly—often in minutes or hours—as new threats emerge.
• Sublime’s approach challenges the traditional black-box solutions used by other email security platforms, providing organizations with comprehensive protection and unmatched visibility.

Future of Email Security with AI

5. GenAI’s Impact on Email Security

• Josh Kamdjou, Founder and CEO of Sublime Security, emphasized that Generative AI has fundamentally changed the economics of phishing and email security.
• Sublime’s flexibility in addressing new attack techniques positions the platform as the future of email security, helping security teams tackle the ever-evolving threat landscape.
• With this new funding, Sublime aims to accelerate its mission to make email safer for organizations worldwide.
