Aether Biomachines — Startup Profile

Designing industrial proteins with computers and biology.

HQ: San Francisco, California, United States | Founded: 2020 | Employees: Not publicly disclosed | Stage: Growth-stage private | Website: https://aether.bio

About

Aether Biomachines designs proteins for industrial jobs such as making strong fibers and advanced materials. It combines computer models with laboratory testing to explore proteins that do not occur naturally or are hard to produce in useful quantities.

The Take

Aether is pursuing a difficult but promising route to better materials: design proteins that can be made by biology rather than by energy-intensive industrial processes. Commercial success will depend on producing those proteins at scale and finding customers willing to redesign manufacturing around them.
