Selected work

Devices we designed, built, and shipped

The work below is the founders' own — doctoral research and ventures carried out at Johns Hopkins, UC Irvine, and Michigan before and alongside RNS. We show it because it is the most honest evidence of how we engineer. Client engagements are covered by agreement and appear here only with approval.
