Programmable biobots for tasks that conventional systems can’t do.

Fauna Systems is developing tiny, biodegradable biobots that can move, sense, respond to their surroundings, and then safely break down afterward. We’re exploring where these capabilities unlock value in complex environments where chemistry, machinery, and traditional automation fall short.

Agential engineering

The next big opportunity in AI

AI learned to talk. Then it learned physics. Then it learned to move a robot. Agential engineering is the next step: AI that designs living systems with agency of their own.

  1. Stage one

    Large Language Models

    Trained on text to predict the next word. No agency in the physical world.

  2. Stage two

    World Models

    Learn the physics of things. Confined to simulation.

  3. Stage three

    Embodied Intelligence

    Intelligence uses a robot to learn and to act. The robot is made from inanimate materials.

  4. Stage four

    Agential Engineering

    Form and function discovered in silico with AI. Built from living materials with sensing, smarts, and agency “out of the box”. Trained to do valuable work.

Agential engineering: language beyond humans, psychology beyond physics, embodiment beyond movement.

Biobots are the first product of agential engineering. Mombot, the anatomical compiler that designs biobots, is the tool that discovers and produces all new systems made with agential components.
