|---|---|---|---|---|---|
| Oct 2026 | Series C | Sequoia Capital (lead); Y Combinator; GV; Premji Invest; Peak XV Partners | $66M | $1B | Blacksmith announced on 21 October 2026 a USD 66 million Series C led by Sequoia Capital at a USD 1 billion valuation. Premji Invest joined, and existing investors Peak XV Partners, GV and Y Combinator participated. The round brings total funding to about USD 125 million and follows a USD 45 million Series B led by Peak XV Partners about two months earlier at a USD 550 million valuation. The company said the proceeds will grow its team and expand its compute footprint. Blacksmith runs infrastructure for building and testing code, known as continuous integration, and its founders built it on the bet that testing code rather than writing it would become the constraint on shipping software. The company was founded in 2024 by Aditya Jayaprakash, Aayush Shah and Aditya Maru. Weekly jobs on the platform grew from 5 million to more than 90 million since January and annual recurring revenue grew 17 times, with more than 10,000 companies including Ashby, Granola, Handshake and LangChain among its users. |
| Aug 2026 | Series B | Peak XV Partners (lead); Y Combinator; GV | $45M | $550M | Blacksmith raised a $10 million Series A led by Google Ventures, following its earlier $3.5 million seed round also backed by GV and Y Combinator. The round was closed quickly and was used to accelerate product development and scale the company’s CI/CD infrastructure business. The strategic rationale was to fund growth in a market where faster, cheaper software build and test infrastructure is becoming more important, especially for teams using GitHub Actions and AI-driven development workflows. Blacksmith’s investor base also included prior backers and notable angels, signaling strong support from the developer-tools ecosystem. Blacksmith is a Y Combinator-backed startup focused on high-performance continuous integration cloud services. The company has partnered with over 600 organizations and reached more than 700 customers with about $3.5 million in annual recurring revenue. Its product positioning centers on faster builds, lower compute costs, and observability for engineering teams. |
| May 2026 | Undisclosed stage | - | $45M | - | Blacksmith raised $10 million in a Series A led by Google Ventures, with participation from existing investors and angels; the round closed in 14 days. The company had previously raised $3.5 million in a seed round led by Google Ventures and Y Combinator in May 2025. The financing was aimed at accelerating Blacksmith’s CI cloud and GitHub Actions observability product, with planned expansion of engineering and go-to-market hiring and new offices in San Francisco and New York City. Blacksmith’s positioning in the round was tied to demand for faster, more cost-effective CI infrastructure and deeper test analytics for engineering teams. Blacksmith is a developer tools company focused on high-performance CI for GitHub Actions and broader CI/CD workflows. The company’s publicly disclosed scale in the available results centers on its funding history and product roadmap rather than operating metrics; no revenue or EBITDA figures were disclosed in the provided results. |

Blacksmith raised $10 million in a Series A round on September 17, 2025, led by Google Ventures (GV) just four months after its $3.5 million seed round also backed by GV and Y Combinator. The rapid 14-day close included participation from angels like Spencer Kimball of Cockroach Labs and David Cramer of Sentry. The funding will expand engineering and go-to-market teams, open offices in San Francisco and New York City, and build observability features like test analytics. At the time of the Series A, Blacksmith achieved $3.5 million in annual recurring revenue (ARR), up from $1 million ARR in February 2025, with a lean team of eight employees. The company aims to double ARR by year-end, demonstrating strong traction with hundreds of customers acquired since the seed round. |
| May 2025 | Seed | GV (lead); Y Combinator (lead); Theo Browne; Peter Mattis; Eli Brown; Richard Aberman; Spencer Kimball; Machina Ventures; JJ Fliegelman | $4M | - | Blacksmith builds a high-performance CI cloud platform optimized for AI-era development workflows, serving as a drop-in replacement for GitHub Actions runners that is twice as fast at half the cost. The platform uses a purpose-built bare-metal hardware-software stack powered by gaming CPUs for high single-core performance, providing fast compute, observability, and security for CI workloads. Founded by veterans from Cockroach Labs and others, it addresses bottlenecks in legacy CI systems like GitHub and AWS amid rising code volume from AI agents.

At the time of the round, the platform powered CI for over 600 organizations, including Ashby, Veed, Finch, Clerk, Pylon, Plex, and Mintlify. Funds support team growth and development of observability and security layers atop fast compute. Blacksmith competes in the developer tools market by cutting CI/CD costs and doubling speeds through bare-metal infrastructure, positioning for AI-driven demand.
