Company Culture

Our culture

*Culture is the collective behavior of everyone in the company when nobody is watching. Ben Horowitz*

Valiu only works well if we all work together towards the same goal. At Valiu, your success is only a result of the company's success (Team > Heroes), so let's work together to achieve our mission. If you see something below standard and do nothing, then you’ve set a new standard.

Our motto: ask for forgiveness, not permission.

1. We learn fast:

The best companies are the ones that learn faster, which is why we are working to develop a learning culture, one that encourages everyone to ask difficult questions and set themselves challenging goals.

2. We improve and organize every day:

It is vital that everyone on the team strives to improve themselves every day. At Valiu, we know that nobody is perfect and we understand that learning from our mistakes is what makes us better. That said, **we do have high general expectations of you and we expect that you become an expert at organizing your tasks, goals, issues, meetings, etc.

3. We apply velocity:

Without fast, constant iteration and innovation, a venture fails. We need you to be flexible, work long hours, weekends, and make sacrifices. Inform your perspectives, and adapt to new roles quickly, whenever necessary. Everyone does product QA (testing and bug reporting) at Valiu in order to move fast and ship amazing products.

Competition is for losers Peter Thiel

4. We play the infinite game:

In game theory, a finite game is one with a set of rules and roles. If we were the best financial institution in the world, our goal would be finite once we've succeeded. On the other hand, at Valiu we are building to last and competing against ourselves. We strive to stay ahead of the curve in an ever-changing environment.
