Announcing our partnership with Sequoia and a new era of cybersecurity

Written by Tim Sadler, CEO & Co-founder, Tessian

I’m delighted to officially share with the world today that Tessian’s raised $42m in Series B funding led by Sequoia and partner Matt Miller is joining the board.

I got to properly know Sequoia and Matt last year after a destiny-crafting introduction from the legendary CyLon. We’ve been fortunate to have a lot of interest from investors, but I try not to take meetings unless we’re actually fundraising. Sequoia was different. Instead of spending time talking about ARR and our metrics, Matt was interested in our vision, founding story, team and challenges. Sequoia call themselves company-builders, and that’s exactly how it felt from day one. We couldn’t be more excited to welcome Matt to the Tessian board and to work with him to create a new category of enterprise cybersecurity.

When Tom, Ed and I started Tessian in our apartment in 2013, we started with a grand vision but laser focus on trying to execute one thing extremely well—preventing sensitive data loss caused by human error. Over the past three years, we’ve been quietly expanding the capabilities of our machine learning engine to address other gaping holes in enterprise security. Today, we’re also delighted to share our vision with the world for the very first Human Layer Security platform for the enterprise. Enterprises have spent the past two decades protecting their networks with firewalls, their devices with endpoint security but have completely neglected the most important data processors of all—their people. The new capital raised in our Series B will allow us to leverage the technology we’ve applied to email security and expand this to provide automatic protection for the myriad platforms and applications in use everyday by people in global organizations.

Of course, none of this would have been possible without our most important allies. First, I’d like to thank all of our customers for their incredible support and belief in us over the years. Cybersecurity, by definition, is a risk-averse industry. It’s been inspiring to see how many enterprises are willing to adopt new technology to solve their greatest problems. Second, and to whom we owe the greatest thanks—the employees of Tessian. It’s because of your brilliance, creativity and relentless grit that we’ve achieved what we have today.

As I’m sure any founder will attest, fundraising is a necessary part of company building but not the ultimate goal. We now have a huge amount of work ahead as we execute against our plans for 2019—a year that’s shaping up to be our biggest yet.
