The Difference

How we work


It’s almost silly not to leverage the strengths of those around you to get ahead - and when you work from home, you lose that completely.


When everyone else is still working at 6 o’clock on a Friday, you’ll think twice about packing up to go home. We push each other to do better work.


Coworking is all about working together. Everyone is here to bounce ideas off of, brainstorm with, and troubleshoot with. 


At the end of the day its what you sell that pays the bills. We want to help you build that better than your competitors.

About us

Meet our team

We are two recent entrepreneurs looking to bring coworking to the East Bay. Tired from working at home and not being able to find suitable office space where we could thrive, we came together to create Critosphere to build new relationships and challenge our ideas.
