Kontakt.io is a fast-growing company. It is extremely important for us to work with people who value the same virtues and fit our culture. Successful cooperation means that you:

Lead customer-centric - customer leadership is the key. If a customer has a problem we don’t wait. We understand what customer needs and we tailor our services products around the customer. It doesn’t mean that we let the customer lead us. It means that we think about the customer first.

Have a growth mindse t - we commit to results and growth. We are responsible for results not for the activity or time spent. If we believe we can’t achieve a result or a job it’s our duty to raise the voice push back explain what we suggest instead. We don’t see results as something static - ever. This means that our results and expectations are becoming more ambitious quarter over quarter. We constantly evolve

Challenge inspire respect - we are the challenger in the marketplace. When working with each other - or with customers - we enjoy and desire to challenge each other. We listen reflect and respond. We aim to understand the point of view of the other party and if there is customer merit in the argument. When we challenge we articulate our hypothesis clearly and provide data and evidence in our argumentation. We respect the time of our colleagues. We have a zero-tolerance towards discrimination of any kind. We respect the environment.

Execute systematically - We recognize that the start-up journey will only be successful if we learn twice as much as others in half the time. For us innovation also means continuous improvement in all fields. We think in systems when driving results growth and learnings.

Act with urgency - We have a sense of urgency in everything we do - at all times. It’s deeply rooted in the belief that as an up-start as a challenger we need to drive value for our customers faster and better than anybody else in the marketplace. We do things outside of the personal comfort zone.
