High-Level Overview
BuildJet is a high-performance computing cloud company that specializes in accelerating continuous integration (CI) workflows for software development teams. Its core product is a drop-in replacement for GitHub Actions runners, leveraging dedicated gaming CPUs to deliver up to 2x faster and more cost-effective builds. By optimizing for high single-core performance, BuildJet addresses a key bottleneck in traditional CI/CD pipelines, which often rely on server CPUs with weaker per-core speed. The company serves developers and organizations seeking to reduce build times, lower infrastructure costs, and streamline their release cycles. Since its launch in 2022, BuildJet has demonstrated strong growth momentum, raising $1 million in funding, achieving $330K in monthly revenue by late 2025, and maintaining a lean team of just three employees.
Origin Story
BuildJet was founded in 2022 by Adam Shiervani and Lian Duan, both experienced technologists with a background in scaling startups in Berlin. Their idea emerged from firsthand experience at a previous company, where they observed the dramatic impact that gaming CPUs could have on CI speed compared to standard server hardware. Recognizing a widespread pain point among developers using GitHub Actions, they set out to build a cloud platform that could deliver the performance benefits of gaming CPUs at scale. The company quickly gained traction, joining Y Combinator’s Winter 2023 batch and securing early funding from notable investors, including Creandum and founders of Reddit, Cruise, Rappi, and Instacart. Their early success was marked by rapid adoption and a growing reputation for delivering measurable performance improvements.
Core Differentiators
- Gaming CPU Cloud Infrastructure: BuildJet’s use of high-performance gaming CPUs provides a fundamental speed advantage over traditional server CPUs, especially for CI workloads that benefit from strong single-core performance.
- Drop-in Replacement: Users can switch to BuildJet with just one line of configuration, making adoption seamless and frictionless.
- Custom Bare-Metal Infrastructure: The platform is built on dedicated, custom-optimized hardware, ensuring consistent performance and security.
- Fast, Reliable Caching: BuildJet offers a high-speed caching solution powered by Cloudflare R2, with 20 GB of free storage per repository per week.
- Usage-Based Pricing: Flexible pricing per minute of runner usage, with options for AMD and ARM architectures and scalable concurrency.
- Security: Isolated virtual machines and one-time token authentication ensure secure workflow execution.
Role in the Broader Tech Landscape
BuildJet is riding the wave of developer tooling innovation, where speed, cost, and ease of use are increasingly critical as software teams scale. The shift toward cloud-native development and CI/CD automation has created a growing demand for infrastructure that can keep pace with rapid iteration cycles. By focusing on the underappreciated role of CPU architecture in CI performance, BuildJet is helping to redefine what’s possible in cloud-based developer infrastructure. Their approach aligns with broader trends in the tech ecosystem, including the move toward specialized hardware for specific workloads and the increasing importance of developer experience in competitive markets.
Quick Take & Future Outlook
BuildJet is well-positioned to become a key player in the CI/CD infrastructure space, especially as more teams seek to optimize their development pipelines for speed and cost. The company’s focus on gaming CPUs as a performance differentiator is both novel and highly relevant, given the ongoing evolution of cloud computing and the rise of specialized hardware. Looking ahead, BuildJet is likely to expand its platform to support additional CI/CD tools and workloads, while continuing to refine its infrastructure for even greater efficiency. As the demand for faster, more affordable developer tools grows, BuildJet’s influence on the broader ecosystem could extend beyond GitHub Actions to shape the future of cloud-based software development.
