Codesmith is a cloud coding agent from Blacksmith that developers can delegate tasks to, covering building features and fixing bugs, and it also works inside the CI validation loop by diagnosing failures, autofixing them, and keeping pull requests green. It serves as the foundation for codesmith QA, which will autonomously test changes before merge. _Developers evaluating cloud coding agents for CI workflows can follow updates like this on daily.dev._ ## Similar posts on daily.dev - [AI code-testing startup Blacksmith’s valuation jumps almost 10x in less than a year](https://daily.dev/posts/ai-code-testing-startup-blacksmith-s-valuation-jumps-almost-10x-in-less-than-a-year-bbbkrwprm) · TechCrunch · 0 upvotes · 0 comments --- Tags: [#venture-capital](https://daily.dev/tags/venture-capital), [#cicd](https://daily.dev/tags/cicd), [#github-actions](https://daily.dev/tags/github-actions) [View this post on daily.dev](https://daily.dev/posts/blacksmith-raised-45m-series-b-funding-for-faster-code-validation-kgzzqxgxb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Blacksmith Raised $45M Series B Funding for Faster Code Validation","url":"https://daily.dev/posts/blacksmith-raised-45m-series-b-funding-for-faster-code-validation-kgzzqxgxb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/blacksmith-raised-45m-series-b-funding-for-faster-code-validation-kgzzqxgxb"},"datePublished":"2026-08-13T09:11:18.092Z","dateModified":"2026-08-13T09:11:38.657Z","description":"Blacksmith, which offers faster and cheaper drop-in replacement runners for GitHub Actions, raised a $45 million Series B led by Peak XV Partners with...","image":"https://media.daily.dev/image/upload/s--1KxV4ohY--/f_auto/v1722860400/public/Placeholder%2007","thumbnailUrl":"https://media.daily.dev/image/upload/s--1KxV4ohY--/f_auto/v1722860400/public/Placeholder%2007","isAccessibleForFree":true,"articleSection":"Software Testing Magazine","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Software Testing Magazine","logo":"https://media.daily.dev/image/upload/s--51CB3vDJ--/f_auto/v1721572881/logos/softwaretestingmagazine","url":"https://daily.dev/sources/softwaretestingmagazine"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/blacksmith-raised-45m-series-b-funding-for-faster-code-validation-kgzzqxgxb","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"venture-capital,cicd,github-actions","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Software Testing Magazine","item":"https://daily.dev/sources/softwaretestingmagazine"},{"@type":"ListItem","position":3,"name":"Blacksmith Raised $45M Series B Funding for Faster Code Validation"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/blacksmith-raised-45m-series-b-funding-for-faster-code-validation-kgzzqxgxb#faq","mainEntity":[{"@type":"Question","name":"How much faster and cheaper are Blacksmith's GitHub Actions runners compared to GitHub-hosted runners?","acceptedAnswer":{"@type":"Answer","text":"Blacksmith claims its GitHub Actions runners run twice as fast and cost 75% less than GitHub-hosted runners.
