About Circles:

We’re Circles, a well-funded startup based in the heart of Tel-Aviv, on a mission to reduce loneliness through the power of group support. We believe no one should face life’s challenges alone, and that support from those who’ve been there is invaluable. Our revolutionary platform ensures everyone, everywhere, has access to the emotional support they need to feel better.

Excitingly, we are currently integrating AI into our platform to make mental health support even more accessible, personalized, and available anytime, anywhere. This is a unique opportunity to contribute to a cutting-edge application of AI for social good.
