Tessian Raises $42M in Series B Funding

tessianTessian, a London, UK-based security platform aiming to reduce the chances of human security breaches, raised $42m in a Series B funding.

The round was led by Sequoia, with participation from Latitude and existing investors Balderton Capital and Accel. In conjunction with the funding, Matt Miller, Partner at Sequoia, will join the Tessian board.

The company intends to use the funds to accelerate its expansion in the US and other global markets, as well as to invest in research and development to expand their product line in 2019.

Led by Tim Sadler, CEO and co-founder, Tessian has developed a technology system that uses machine learning to eliminate the huge security vulnerabilities surrounding enterprise email including spear phishing and misdirected emails. The platform analyzes historical email data in order to understand the context of human relationships and communication. By knowing what normal email activity looks like, it can automatically detect any anomalies that may imply a security threat.
The company serves a global customer base across the legal, financial, technology and healthcare sectors. Clients include international law firms Clifford Chance and Dentons, financial institutions Schroders and Investec and FTSE 100 company Rightmove.
