Extending human intelligence beyond biology

Intelligence needs new infrastructure.

Complexure builds injectable wireless microsensors that read and write to the cortex at single-neuron resolution. No surgery. No gene therapy. No tethered hardware.

One architecture, both directions. One addressing scheme scaling to hundreds of thousands of nodes.

This is the interface layer between biological and machine intelligence. It begins in the labs decoding neural circuits today.

Where we are

One architecture, one signaling scheme, both directions: the substrate for closed-loop neural systems at scale.

Wireless detection of neural-scale signals in saline.
What lasts

What compounds is not the sensor. It is the bidirectional causal data the sensor generates.

Reading brain activity only shows correlation. A read-only interface captures neither the intervention nor its effect. Writing to a circuit and reading its response shows causation because you control the stimulus and observe the response. Each sensor does both, so every deployment adds to the causal record, and that record compounds into a model of cognition.
