What Drives Us

Tessian’s Six Guiding Values

We believe people are the most important decision makers in any organization. We’re a group of data scientists, engineers, designers, creative thinkers, and commercial experts who are passionate about protecting people processing data in the enterprise.

Human first.

We approach everything with empathy and we look out for each other alongside our own wellbeing. Respect, kindness and inclusion are at the core of our company because our people are what make us Tessian.
Customer centricity.

They're the lifeblood of our business and guide our daily decision-making. Whether we're launching a feature, or pursuing a partnership, we always ask "How does this help our customers?
Positive mindset. Solution oriented.

We lead with a curious, positive mindset, and go above and beyond to find solutions when problems arise. When our solutions fail, they fail fast - we embrace the failure and keep learning, iterating, and improving.
Grit and perseverance

We have sustained passion for achieving long-term goals. We see setbacks as opportunities to adapt and grow. We're committed to building the resilience and motivation to tackle big challenges that others might give up on.
We do the right thing.

We're always honest and guided by integrity in every decision we make, with one another, with our customers, with everyone. We do what we believe is right, even when it means making difficult decisions.
Craft at speed.

We work with great care and skill, sometimes at an uncomfortably fast pace. Rather than aim for perfection in one at the expense of the other, we balance attention to detail with speed of delivery.
