Attune: 20x Faster Builds with Zero Migration Effort

In the fast-paced world of software development, speed is everything. Thanks to generative AI tools like GitHub Copilot and ChatGPT, writing code is faster than ever before. But even as coding accelerates, developers are still shackled by a critical bottleneck: slow builds.

Build systems—essential for compiling, testing, and deploying code—often lag behind, turning a few seconds of coding into tens of minutes of waiting. Developers might write a feature in 60 seconds, only to sit idle for half an hour while the code compiles and runs through a bloated CI/CD pipeline. This lag doesn't just waste time; it breaks focus, hinders iteration, and reduces overall development velocity.

Historically, solutions like Bazel or custom distributed build systems have offered relief, but at a cost. These tools demand painful migrations, steep learning curves, and often a complete overhaul of existing workflows. Attune was created to fix this with a new approach: zero-effort acceleration.

How Does Attune Solve the Build Bottleneck?

Attune’s value proposition is refreshingly simple: blazingly fast builds with zero migration effort.

Instead of forcing engineering teams to adopt entirely new toolchains, Attune integrates directly with existing compilers and build tools. It introduces speed where it matters, without altering the developer’s workflow. The magic lies in replacing a simple command: for Rust developers, switching from cargo build to hurry cargo build is all it takes to unlock up to 20x faster builds.

Under the hood, Attune uses a combination of:

• Incremental builds to avoid recompiling unchanged code
• Remote execution to offload work to faster cloud machines
• Distributed caching to prevent redundant build tasks
• Compiler-native optimizations tuned for each supported language

This native, drop-in philosophy makes Attune a uniquely frictionless performance upgrade. Developers don’t have to rewrite build files, study new documentation, or configure complex settings. It's productivity on demand—just faster.

Who Are the Founders Behind Attune?

Attune was founded by two seasoned veterans of developer tooling: Xin Ding (CEO) and Eliza Zhang (CTO). Their partnership spans several years of collaboration at FOSSA, where they tackled deep technical problems in build systems and compliance automation.

• Xin Ding previously served as VP of Product at Teleport (Y Combinator S15), scaling its SaaS product from zero to 8-figures in ARR. Prior to that, he led product at FOSSA from the seed stage through rapid growth. Xin has a proven ability to build tools developers actually want—and scale them to unicorn success.
• Eliza Zhang brings a decade of experience in programming languages and build systems. Before leading engineering at FOSSA, she worked at Google on various build system teams. At FOSSA, she pioneered zero-configuration build analyses that drastically cut customer onboarding time. Her expertise is grounded in both theoretical depth and pragmatic implementation.

Together, Xin and Eliza combine technical excellence with market intuition, and they are building Attune not just for others, but for themselves, solving a pain they’ve experienced firsthand.

Why Is Zero-Migration a Game-Changer?

In the world of developer tooling, even great products fail if they demand too much change. Developers are notoriously averse to migrating away from tools they trust, especially if those migrations risk breaking things in production.

Attune understands this. That’s why it positions itself not as a replacement but as an overlay. The simple hurry prefix turns existing commands into turbocharged versions of themselves.

This approach ensures:

• No learning curve — Developers don’t need training
• No rewrites — Teams don’t touch their build configurations
• No vendor lock-in — It’s as easy to remove as it is to adopt

With support currently available for Rust and plans to expand into Docker and more languages, Attune is set to become the universal speed layer for software builds, one line at a time.

What Makes Attune’s Technology Unique?

Many developer tools promise speed, but Attune delivers it by operating at the compiler and build-system level. Rather than acting as a wrapper or abstraction layer, Attune integrates natively into the build chain.

This is not a superficial speed boost. Attune’s architecture is built to:

• Understand and optimize code paths in real-time
• Hook into language-specific build pipelines
• Support distributed workloads with intelligent job scheduling

By staying close to the metal, Attune avoids the overhead and opacity of generic acceleration tools. Its deep integration enables granular performance tuning, tailored to each language and use case.

Furthermore, Attune’s decision to focus on zero-configuration means developers get results from day one, with no need to “set up” Attune as a service. It’s the closest thing to flipping a switch for productivity.

What Is Attune’s Vision for the Future?

Attune isn’t just a build accelerator—it’s the first step toward reimagining how software is assembled in the AI age.

As generative AI and low-code tools continue to accelerate programming, every part of the development pipeline needs to keep pace. Build systems, once background infrastructure, are now the weak link. Attune aims to make them invisible again by making them fast enough to never be noticed.

In the near future, the team plans to:

• Expand support to additional languages (Go, Python, JavaScript, etc.)
• Integrate with CI/CD systems and cloud-native environments
• Provide performance analytics and optimization insights for teams
• Introduce team-based caching and remote execution clusters

Their long-term goal? A world where “slow builds” are a thing of the past, and development cycles move at the speed of thought.

Why Are Developers and Investors Paying Attention?

Attune was accepted into Y Combinator’s Spring 2025 batch—a signal that it’s a startup to watch. In a field crowded with shiny but unproven tools, Attune’s pragmatic approach, seasoned founding team, and dead-simple adoption path stand out.

The developer tools space is notoriously hard to crack. It takes deep technical credibility and product intuition to win over engineers. But Xin and Eliza have done it before, and Attune is their most focused bet yet.

As build times continue to drag productivity down, tools like Attune aren’t just nice to have. They’re inevitable.

Final Thoughts: Is Attune the Future of Builds?

Build speed has always been a developer pain point, but in 2025, it’s becoming existential. In an age where code can be written in seconds, waiting for builds is not just annoying—it’s unacceptable.

Attune fixes this with elegance: no migration, no retraining, no disruption. Just faster builds, starting today.

Whether you’re a solo Rustacean or part of a 100-person engineering team, Attune invites you to stop waiting and start building.
