Convex has raised $57 million in a Series B funding round. These funds are planned to be used to scale the development of its backend platform, which is specifically designed for artificial intelligence. The financing was led by Insight Partners, with participation from Etna Labs and all previous investors, including a16z and Spark Capital.
Thanks to this Series B round, Convex's total raised capital has reached $110.5 million. The company stated that it intends to use this money to improve its core platform, enhance tools for agentic development, and increase its staff in its San Francisco office.
Founded in 2021 by former Dropbox infrastructure engineers, Convex offers developers a fully integrated backend platform. This platform combines databases, functions, workflows, search, synchronization, authentication, and file storage into a single solution built for software development.
The fundraising comes amid the trend towards AI-powered coding and autonomous development tools. Convex believes that developers need infrastructure capable of handling the increasing complexity of applications while maintaining a high level of reliability.
The company posits that traditional backend infrastructure struggles to support the growing use of AI coding agents. According to the company, AI-generated applications based on standard databases can subtly introduce data errors that only manifest after deployment.
Internal testing revealed that 90% of AI-built applications running on traditional databases encountered data corruption in real-world operating conditions. In comparison, applications developed on the Convex platform passed the same tests without any failures.
Convex's backend includes built-in ACID transactions, end-to-end type checking, real-time subscriptions, and TypeScript support. These features reduce the need for manual integration of multiple services for developers and increase application reliability. Furthermore, Convex packages search capabilities, workflow automation, authentication, file storage, and retrieval-augmented generation functions, allowing AI applications to be enriched with organization-specific knowledge.
The platform has gained significant traction among developers building AI-based software. Convex currently supports nearly two million applications created by about 500,000 developers worldwide. The company also reported over 1.2 million weekly downloads from npm.
Convex's clients include OpenAI, Tripadvisor, Solana, Zapier, and Reducto. These organizations use Convex to simplify backend development while ensuring scalable, reliable performance for their applications.
Insight Partners noted that the growing adoption of AI coding assistants has exposed weaknesses in traditional software infrastructure. The investment firm believes that Convex provides developers with a more robust foundation where backend components function cohesively without the need for complex configuration.
Convex plans to use the new funding to accelerate product innovations amidst the transformation of software engineering influenced by AI. The company will direct funds toward creating new tools that simplify application development for both developers and AI agents that build software.
The company will continue to provide highly reliable backend products supporting increasingly complex AI-based applications globally. Convex is convinced that stable backend infrastructure is becoming critically important as artificial intelligence generates large volumes of application code.
Instead of combining disparate components, Convex offers a single unified platform, which effectively reduces complexity and prevents software bugs. The raised funds will strengthen Convex's engineering team and significantly expand its global developer ecosystem and platform capabilities. With fresh capital and a growing customer base, Convex aims to solidify its position in the evolving AI development infrastructure market, making the creation of reliable software faster and easier for both human developers and AI agents.
