Our principles
Our principles shape the culture we’re building at Cocoon and guide us in maximising our impact.
01
Embrace uncertainty, seek clarity
What we’re doing will always have uncertainties, whether it’s because of the nature of scientific experiments or the fact that we’re an early-stage start-up. Sometimes the answer will be “I don’t know”, but this is best coupled with “we can find out by…”.
02
Champion the power of people
We’re building an incredible team of people with a range of skills, superpowers and experiences. Great ideas, advice and feedback can come from everywhere. We’re not afraid to share our thoughts or seek input from others.
03
Safety is a priority
We’re building equipment for heavy industry, which involves potential hazards. Safety is front of mind when running experiments, developing technology and working with clients.
04
Take ownership, drive progress
We empower every individual to take ownership of their work and drive meaningful progress. From idea generation to execution, we encourage autonomy, initiative, and accountability.
05
Find the fun
We’ve got a big challenge ahead of us, but that doesn’t mean it can’t be fun too. We believe that when work feels like fun, it sparks creativity, strengthens collaboration, and builds resilience.
