- Blacksmith raised a $45M Series B round led by Peak XV Partners
- Blacksmith was valued at $550M in the new round, roughly 9x its prior $60M mark
- Blacksmith had previously closed a $10M Series A in 2025
- Peak XV Partners led the round as the primary institutional backer
- The startup focuses on AI code testing and validation, which the source frames as the next big software development challenge as AI accelerates coding speed
Why it matters: Blacksmith's valuation leaped roughly 9x in a single round — from $60M to $550M — following a $10M Series A earlier in 2025, with Peak XV Partners leading. The source explicitly frames AI-driven code testing and validation as the next major software development bottleneck, and this round shows investors are pricing that layer aggressively.
