CROSS-CATEGORY: Three AI DevTools Companies Raise $4.15B Combined in Five Days — Coding Infrastructure Becomes Hottest VC Category

CNBC·high signal

Between April 16-19, three AI coding infrastructure companies raised a combined $4.15B: Cursor ($2B at $50B+ valuation, Thrive/a16z), Factory ($150M at $1.5B, Khosla/Sequoia), and Cerebras filed for a $2B IPO at $23B. All three target different layers of the developer stack — IDE (Cursor), autonomous agents (Factory), and silicon (Cerebras) — but converge on the same thesis: AI-native development infrastructure is replacing the traditional devtools stack. When three unrelated companies in the same meta-category raise this much capital in under a week, it signals institutional consensus that the devtools category is being rebuilt from scratch.
