Convex reels in $57M for its AI-optimized application backend

Developer tooling startup Convex Inc. today disclosed that it has closed a $57 million funding round led by Insight Partners.
Etna Labs, Andreessen Horowitz and Spark Capital also contributed to the Series B investment. It brings Convex’s total outside funding to $110.5 million.
Convex was founded in 2021 by former members of Dropbox Inc.’s infrastructure engineering team. It offers an application backend, a collection of building blocks that companies can use to develop custom software. Using pre-packaged components is significantly faster than creating everything from scratch.
According to the company, one of its platform’s main differentiators is that it’s optimized for artificial intelligence agents. In particular, it helps developers who build Convex-based applications with AI agents mitigate hallucination-related coding errors.
Convex includes a database that replaces standard SQL queries with TypeScript code to mitigate type errors. The platform implements ACID practices, automates real-time data syncing UI patterns that historically required custom code, and provides search, authentication, file storage, and a RAG feature for custom datasets.
CEO Jamie Turner: “Agents reach for the first thing that works, and on most backends the first thing that works is subtly, silently wrong. You’ll find out weeks later, in production… Convex is that discipline packaged as a product.”
Convex disclosed that its platform powers nearly 2 million applications. Customers include OpenAI Group PBC, Zapier Inc. and other major tech firms. Funding will be used to hire and enhance the platform.
