Tessian Cloud Email Security intelligently prevents advanced email threats and protects against data loss to strengthen #EmailSecurity PS We're Hiring!

After beginning my career in corporate law, I joined Tessian as our first customer success hire in 2017. Since then, we've raised over $120m from legendary security investors (Sequoia, Accel, March, etc), grown the company from 10 to ~300 employees and had the privilege of working with some of the most forward-thinking security companies out there. My proudest achievement is the team I've been fortunate enough to build and lead. I currently oversee all elements of the customer org including sales engineering, customer + technical operations, onboarding and customer success. Outside of work, I spend way too much time planning my next kitesurf trip.
