YC Blacksmith v4

Y Combinator

切

CI bottleneck 0:00

Blacksmith runs infrastructure for continuous integration, the checks developers use before shipping code. As agentic coding tools produce more code, validation becomes the bottleneck, not writing.

切

Founders and approach 1:01

The founders came from Waterloo and Toronto, not DevOps. They saw CI as slow and awkward, and built a cloud tuned for CI workloads, using fast gaming CPUs and caching.

切

Growth and scale 5:31

The company grew from a few hundred servers to thirty people. It now supports customers like Langchain, cuts waits from 15 to 20 minutes to 10 to 15 seconds, and is working on autonomous QA.
