# Attune

> Attune is a San Francisco developer-tools startup (YC X25) building drop-in build acceleration for engineering teams. Its tool, invoked by prefixing existing commands with 'hurry' (e.g. 'hurry cargo build'), delivers up to 20x faster builds through incremental compilation, remote execution, and distributed caching - with zero migration and no new config language to learn. Attune started with Rust and is expanding to Docker, npm, GitHub Actions, Swift, and Python. It also maintains an open-source project for fast, secure Linux package publishing. Founded by Xin Ding (CEO) and Eliza, who worked together for three years at FOSSA on build systems.

- **Founded:** 2025
- **Headquarters:** San Francisco, California, United States
- **Founders:** Xin Ding (Cofounder & CEO), Eliza (Cofounder (Engineering))
- **Team size:** 2-3
- **Products:** Attune (hurry), Attune (Linux package publishing), Attune Enterprise Edition
- **Notable:** Accepted into Y Combinator (X25 / 2025 batch), Launched build accelerator claiming up to 20x faster Rust builds with a one-line change, Open-source Linux package publishing project on GitHub (Apache 2.0), ~200+ stars

## Products & services

- **Attune (hurry)** — Drop-in build acceleration. Prefix existing build commands with 'hurry' (e.g. 'hurry cargo build') to get up to 20x faster builds via incremental compilation, remote execution, distributed caching, and compiler-native optimizations. No migration and no new config language. Available for Rust, with Docker, npm, GitHub Actions, Swift, and Python planned.
- **Attune (Linux package publishing)** — Open-source tool for fast and secure Linux package publishing. Supports self-hosted or managed hosting of APT (Debian/Ubuntu) repositories, with local signing of the repository index so users keep control of their signing keys, plus incremental index rebuilds. Written in Rust, Apache 2.0 licensed.
- **Attune Enterprise Edition** — Edition for organizations with advanced security and compliance needs - enhanced security capabilities, self-hosted/on-prem options, and priority support.
