Convex has raised a $57M Series B led by Insight Partners, with participation from Etna Labs, Spark Capital, a16z, and Justin Kan. The announcement frames Convex as a backend platform built for the agentic engineering era, where AI agents and developers co-write code. Key arguments: ACID transactions prevent data corruption from concurrent agent writes, end-to-end TypeScript catches hallucinated field names at build time, and Convex Components provide sandboxed, context-window-sized units that agents can reason about safely. The company reports millions of instances in production, launched Enterprise plans, and added EU data residency. They are also hosting a free one-day conference called Abstract on September 2nd in San Francisco, and are actively hiring.
