AI experiment company

We build the missing stack around AI agents.

Memory, compression, protocols, runtimes, and mission systems for teams building agent-native workflows.

Nexus-PRIME Labs operating stack board with Nexus Prime, tetris.codes, Grain, NXL, and Phantom

Memory

Nexus Prime

Agent memory and control plane for teams that need runtime truth across tools, runs, and decisions.

Give an agentic workflow durable memory, proof, and control surfaces.

Visit Nexus Prime

Compression

tetris.codes

Context compression and token-efficiency infrastructure for long-running AI work.

Reduce context waste while preserving evidence-grade handoff quality.

Visit tetris.codes

Protocol

Grain

AI interface and protocol layer for making agent-facing workflows legible.

Turn a messy product or workflow surface into an agent-ready interface.

Runtime

NXL

Token-efficient language and runtime experiments for AI-native execution.

Explore compact agent instructions, execution surfaces, and runtime protocols.

Missions

Phantom

AI-native product mission system for translating goals into execution packets.

Move from loose founder intent to agent-executable product missions.

Thesis

Agents need more than models.

Useful agent systems need durable memory, cheaper context, legible interfaces, efficient runtimes, and mission control. Nexus-PRIME Labs builds those pieces as experiments first, then turns the durable parts into infrastructure.

Proof surface

Selective pilots

Bring one painful agent workflow.

We work with a small number of teams where memory, compression, protocols, runtimes, or mission systems are the bottleneck.
