The zerohash Culture

All zerohash employees are guided by the following characteristics and core principles:

• Independence/Ownership - An ability to work autonomously. Join zerohash, pitch ideas, and shape the work you do.

• Passion - We are innovating quickly and challenging the status quo. We want you to think big, be creative and ​make a difference every day.

• Collaborative - A good attitude and respect for others. We’re teammates, not co-workers. Everything we do is a shared success and equally a shared failure - we talk in terms of “we” not “me”.

• Initiative - An ability and passion for learning and asking questions. We will champion you, challenge you and push you to achieve your best - and we expect you to do the same.

• Empathy - An ability to listen, respect, and understand your co-workers, customers, and everyone you interact with no matter how different they are to you.

• Adaptability - An ability to respond quickly. We are in a fast-paced industry and so we expect you to be creative when solving a new problem and comfortable under pressure.

• Transparency - We believe that transparency is critical to empowering everyone to make the best decisions, both the company to its people and vice versa.

• Integrity - Integrity creates trust. As both an organization collectively and as individuals, it is our most valuable asset.
