Blacksmith announces $66 million Series C led by Sequoia
Summary: Blacksmith announced a $66 million Series C led by Sequoia Capital on October 21, with proceeds intended for team and compute expansion.
Why it matters: The announcement identifies a Sequoia lead investment in software build-and-test infrastructure, while leaving its individual commitment and investing vehicle unspecified.
Summary
Blacksmith announced on October 21, 2026, that it had raised a $66 million Series C led by Sequoia Capital. The software build-and-test infrastructure company said the financing would support team growth and expansion of its compute footprint. The announced amount is the total round, not Sequoia’s individual investment.
Why it matters
The lead role identifies a substantive Sequoia investment in infrastructure used to build and test software. For diligence readers, the next questions concern how the company deploys the capital and which investment vehicle holds the exposure; the announcement does not establish Sequoia’s commitment size or investment returns.
