Æthos was founded to connect innovators, researchers, and partners committed to ethical and impactful AI.
Æthos was founded to connect innovators, researchers, and partners committed to ethical and impactful AI.
From our bases in Cambridge and Berlin, we bring together startups, leaders, and organizations to ensure AI is built responsibly.

Æthos started as a physical space for AI founders to work and connect. After speaking with hundreds of builders, it became clear that what was missing wasn't just capital or talent, it was a community rooted in trust, shared ethics, and support.
Every innovation we support places human welfare, dignity, and rights at the center of its design and implementation.
We maintain the highest standards of ethical conduct, ensuring transparency, accountability, and responsible use of AI technologies.
We champion groundbreaking ideas that push the boundaries of what's possible while never losing sight of our responsibility to society.
We believe the best solutions emerge from diverse perspectives, fostering a truly global community of AI innovators and thinkers.
