Infrastructure for the AI Coding Era

Blacksmith is revolutionizing Continuous Integration (CI) by building specialized cloud infrastructure designed specifically for the high-velocity demands of modern software development. Founded by technical "outsiders" who recognized that traditional hyperscalers like AWS are poorly optimized for CI workloads, the company utilizes unconventional hardware, such as high-clock-speed gaming CPUs, to eliminate the bottlenecks caused by slow test validation. This approach has enabled significant performance gains, such as reducing LangChain’s compute acquisition time from 20 minutes to 15 seconds. As agentic coding tools and LLMs exponentially increase the volume of code being written, Blacksmith focuses on scaling its fleet through bespoke observability and geographic distribution to maintain reliability. The company is now expanding beyond pure infrastructure into autonomous QA, providing developers with automated evidence—such as screenshots and video snippets—to ensure code confidence and bring the shipping process closer to the speed of thought.
