High-performance infrastructure for AI agents.
We build the fast parts of the AI stack. Rust-accelerated drop-in replacements for the tools agents actually depend on — LLM gateways, workflow engines, package managers, and developer tooling. Zero config. No rewrites. Just faster.
Multi-agent harness for AI coding tools. Crash-safe state, parallel execution, one CLI. Orchestrates Claude Code, Aider, OpenCode, Codex, and others through a unified workflow layer backed by an append-only event log.

Rust accelerators for LangGraph. Up to 700× faster checkpoint operations. 10–50× faster state management. Drop-in components for production agent workflows that need to be fast and crash-safe.

Make large Git repositories feel instant. A lightweight daemon that watches your files via OS-native watchers, implements Git's fsmonitor protocol, and caches status results. git status in milliseconds instead of seconds.

A drop-in replacement for the Homebrew CLI. 10–100× faster for most operations. Pre-computed SQLite index with FTS5 full-text search, parallel bottle downloads, Ed25519 signed updates, and built-in CVE auditing. Works alongside existing brew installations.

Background workers for Python applications. Add task queues in seconds, without the complexity of Celery or RQ.

The AI agent stack is built on Python libraries that were never designed for production concurrency. LiteLLM's connection pool uses stdlib locks. LangGraph checkpoints serialize through a single thread. Package managers shell out to Ruby.
We fix these bottlenecks one at a time: profile, rewrite the hot path in Rust, ship as a drop-in replacement. Your code doesn't change. It just gets faster.
