Our Sentian Values



We regularly leave our comfort zone.

We challenge ourselves more than Sentia challenges us.

We have realistic views of our skills and always look for ways to improve.

We accept mistakes, but we strive for zero repeats.

Always transparent


We communicate clearly, concisely and often.

We share our thoughts and concerns immediately with honesty.

We don’t make assumptions, we rather ask that extra question.

We don’t rely on emails alone for perfect communication

Listen first

Listen first

We focus on listening rather than responding.

We take the approach that everything is a hypothesis and we could be wrong.

Internally we also listen. If you have an idea or a problem; we are here for you.

We understand first before we try to be understood

Extreme Ownership

Extreme Ownership

We do what we say and say what we do (and don’t do).

We take ownership, always willing to go the extra (s)mile.

We are accountable and document our work (and time).

We strive to exceed expectations (of customers, team members, partners).



We don’t speak negatively about colleagues or customers.

We look at the upside first when change presents itself.

We don’t complain, but there’s always room to share our concerns.

We never miss an opportunity to give positive feedback.
