Announcing our $65M Series C led by March Capital

Tessian’s mission is to secure the human layer by empowering people to do their best work, without security getting in their way.

Today, I’m thrilled to share the news that Tessian has raised a $65m Series C led by March Capital with participation from existing investors Sequoia Capital, Accel, Balderton Capital and Latitude and new investor Schroder Adveq!

Tessian has achieved a huge amount since our Series B funding in early 2019. 

From the first meeting we had with March Capital, it was clear that we shared the same vision. March Capital’s experience with Crowdstrike and KnowBe4 not only showed them what it takes to build a category leader in security, but also, made it clear that so many challenges still remain to be solved. 

As with our Seed, Series A and Series B, what’s always the most important thing, though, is the people who you’re going to be working with. I’m delighted to welcome Jamie Montgomery to Tessian’s Board of Directors and couldn’t be more excited to partner with him, Jed Leidheiser and the whole team at March Capital on our next chapter of growth. I’m also excited to welcome Schroder Adveq to our investor base. Schroders and their security team have been invaluable supporters of Tessian right from the start when they became one of our first ever customers. It’s a great honor and a proud moment to have one of our first customers join our Series C and now support us as investors.

Tessian’s Series C marks an incredible new chapter for our company. The capital raised will be used to investing heavily in R&D to expand Tessian to secure other interfaces and communication channels beyond email, as well as bringing Human Layer Risk Scores to enterprises around the world, helping them quantify the security strengths and weaknesses of every single employee in their organization. We’ll also be expanding our go-to-market teams in the US, UK and beyond, as well as launching our first partnership programs led by our newly formed Business Development team. 

But the most exciting thing about this Series C announcement is how it will help our customers. Every single minute Tessian’s behavioral intelligence models prevent 36 human layer security incidents. This new round of funding will see us continue to invest heavily in building world class Customer Success and Product teams to serve the security teams that rely on their human layer security. I’d like to take this opportunity to say a huge thank you to all of our customers. Without your support and trust none of this would be possible. Tessian would still be a concept in the sketchbook of Ed Bishop (my co-founder and Tessian’s Chief Technology Officer), not the company it is today. 

And last but by no means least, the biggest thank you of all goes to our employees and the tireless, mission-driven work you put in every day to build our incredible company. Tessian shines so brightly because of your brilliance. 

But as with every fundraise, this is just the beginning. It takes a village and we’re only just getting started. If you know anyone looking to take the next step in their career and to join a company solving the biggest problem in enterprise security today, please get in touch, we are hiring! 🚀
