The fastest way to run your GitHub Actions
Blacksmith is a business in b2b based in Los Angeles, California, US, founded in 2016.
Profile
Blacksmith helps companies run their continuous integration (CI) up to twice as fast, at half the cost. We do this by running their CI on high performance gaming CPUs.
- Engineering productivity is often marred by slow CI that grows quadratically with the size of the engineering organization.
- On top of this, companies pay high markups to run CI on the hyperscalers.
- Consequently, companies have to run their CI on spot instances to keep costs in check. Since spot instances can get pre-empted at any point, running CI reliably on them requires [significant engineering investment](https://www.rippling.com/blog/how-rippling-used-spot-instances-to-save-and-scale-ci-cd).
Blacksmith offers CI compute that is more performant, cheaper, and reliable. With Blacksmith, companies do not have to think about CI as they scale.
We are starting with GitHub Actions - today's most popular and fastest-growing CI system. With a one-line change, companies can run their CI up to twice as fast on our high-performance hardware. In addition to this, Blacksmith provides colocated warm caches along with optimizations for common CI workloads (like building and pushing Docker images).
Aayush, JP and Aditya have gained deep systems and product knowledge from their time at Cockroach Labs and Faire respectively. Both these companies, with several hundred engineers, were spending in the order of
Within the b2b space, the company focuses on its core offering rather than a broad product line.
Its base of operations is Los Angeles, California, US.
The company is listed at the Winter 2024 stage of development.
The company reports a headcount in the 3 range.
Directory analysis
Blacksmith is a B2B startup based in Los Angeles that accelerates continuous integration (CI) for developers by running GitHub Actions on high‑performance gaming CPUs. The company claims to cut CI runtimes in half while reducing costs by about 50% compared to hyperscaler spot instances. It targets engineering teams that need faster, more reliable CI pipelines without the engineering overhead of managing spot instances.
Positioning: Blacksmith positions itself as a niche CI acceleration provider, offering a cost‑effective alternative to traditional cloud CI services. Its focus on gaming‑grade CPUs differentiates it from larger DevOps platforms, but adoption may depend on the scale and budget of engineering teams.
Note: Founded in 2016, Blacksmith operates with a small team of three employees.
