Our Values

The foundations for our decisions and the guiding voice of how we collaborate as a team

Achieve anything with a happy and healthy team

At Castor, the team comes first. We focus on health and don’t compromise work-life harmony. We invest in our Castorians wellbeing and encourage everyone to be physically active, practice meditation, eat healthily, and have fun! This helps us achieve our goal of supporting faster, smarter medical research.

Maximize research impact

Making a difference in the world is what unites, aligns, and drives us. Founded by an MD/Ph.D. who experienced significant problems in medical research data management, we are determined to solve these issues and have a lasting impact on humankind.

Push boundaries through direct communication and diversity

It takes people with different ideas, backgrounds, values, and personalities to accomplish our goals. We actively encourage direct communication, thoughtful debate, and respect for each other’s different points of view.

Amaze through user-friendly and rewarding experiences

We develop user-friendly technology that works for researchers, not against them, and make sure they are wowed throughout their interactions with Castor.

ACT RESPONSIBLY and protect the data

Integrity and honesty are non-negotiable attributes of our team. We are accountable and refuse to sacrifice our values. We respect our customers’ precious data and protect it at all costs.

Our Impact

By bringing clinical trials into the 21st century, we’re helping people to live longer, healthier, and happier lives.
