Eternis is building systems for a world with highly capable AI.

We envision a world where everyone has a digital twin that understands your preferences, evolves with you, makes millions of decisions daily, and coordinates seamlessly with other twins. While power over AGI and resources consolidates into the hands of a few, we're building a different future—one where billions of digital twins govern powerful multi-agent systems with access to capital, physical resources, and real-world agency.
