Superblocks bets enterprises buy governed vibe coding; AWS embeds it in private clouds

Superblocks, founded in 2021 by Brad Menezes and Ran Ma, began as a platform for building internal tools, born from the founders' repeated experience of hand-building the same apps at every company. When generative AI made app creation easy for non-developers, the company reframed the problem: employees were vibe-coding with consumer tools like Replit, Lovable and Claude, creating shadow IT that security teams could not control.

Its answer was Clark, an AI agent announced alongside a $23M Series A extension in May 2025 (total funding $60M, from Kleiner Perkins, Spark Capital, Greenoaks and Meritech). Clark turns natural-language prompts into React applications with audit logging, permissions, SSO and security scanning built in, routing work through specialized agents the way a real internal development team operates.

In August 2026 Superblocks signed a multiyear joint marketing agreement with AWS: Superblocks 3.0 deploys inside a customer's AWS VPC, creates Aurora databases or S3 storage per app inside that perimeter, runs all inference through Amazon Bedrock with admin-approved models, and tests every code change with a swarm of security agents. Data and code never leave the customer's cloud, and AWS sells the product through its Marketplace.

The company's 3.0 announcement cites Virgin Voyages running 15+ production AI-built apps across seven departments with no dedicated frontend engineers, and Matthews cutting a 3-5 day process to 12 hours. It claims enterprise-wide model routing can cut AI inference costs by up to 30%. As of September 2026 the company has 50 employees and is scaling through the AWS channel.
