## About

Based in California, US, founded in 2024, Blacksmith Software, Inc., focuses on improving continuous integration processes for developers by leveraging advanced computing technology. The company was co-founded by Aditya Maru, Aditya Jayaprakash (CEO as of 2026), and Aayush Shah. In August 2026, Blacksmith Software Inc. raised USD 66.26 million in venture funding.

Blacksmith specializes in enhancing the performance of GitHub Actions through its core product, which leverages high-performance gaming CPUs to accelerate continuous integration (CI) workflows. This service allows clients to execute CI jobs significantly faster compared to traditional GitHub-hosted runners. Blacksmith's offering is characterized by a straightforward integration process, requiring minimal code changes to switch from existing systems, thereby facilitating a seamless transition. The company serves organizations utilizing GitHub Actions across various industries, including software development, tech startups, and enterprises focused on optimizing their CI/CD pipelines. With a customer base exceeding 600 organizations, its services are actively utilized in North America, Europe, and parts of Asia.

Blacksmith generates revenue through a subscription-based model targeting organizations using GitHub Actions. Clients benefit from a competitive pricing structure, with the per-minute cost set at half of GitHub's offerings. The service includes a monthly allocation of 3,000 free minutes for new users, allowing organizations to test the platform without upfront commitments. This model encourages ongoing usage and scaling as clients transition to paid plans after utilizing their free minutes. Blacksmith’s flagship services, which include high-performance CI runners and built-in analytics for job performance monitoring, cater primarily to software development teams seeking to enhance productivity and reduce costs.

The company plans to use the funding to broaden its developer infrastructure offerings, expand observability and testing capabilities, and support growing demand from AI-native software teams.
