Superblocks, a vibe-coding startup with 50 employees, has signed a multi-year joint marketing agreement with AWS that embeds its tool inside the cloud giant's private cloud environments. The deal lets enterprises on AWS subscribe to Superblocks and offer vibe coding to business users without sending data outside their own infrastructure.
The arrangement marks a notable shift in how hyperscalers are courting the fast-growing vibe-coding market. AWS will help sell Superblocks to enterprises, much as it does for many Marketplace partners, and the startup's apps will run entirely within a customer's private cloud.
A new home for business-built apps
Vibe coding lets business users create applications using AI, often without formal programming skills. Superblocks has built its business around that idea, and the AWS agreement gives it a direct path into large enterprises that want the capability without the security headaches.
Under the deal, apps built with Superblocks will spin up Amazon Aurora databases inside the company's private cloud. They will not create external Supabase databases, a common choice for vibe-coding apps elsewhere. The apps will also integrate with Amazon Bedrock, AWS's platform for building and running AI applications.
Brad Menezes, co-founder and CEO of Superblocks, said the core promise is simple. "We're going to bring it to your data inside your private cloud," he said.
He stressed that the architecture keeps everything in-house. "The big thing about that is data never leaves. … It's their AWS account and basically secure with all of the auditing, all of the encryption, all of the network controls."
Because the apps run inside the customer's AWS environment, they automatically fall under IT's management and security policies. That could remove a major barrier for enterprises worried about shadow IT and data leakage.
AWS fills a gap in its lineup
AWS does not yet have its own vibe-coding agent aimed at business users. The company has Kiro, an AI coding agent for developers, but Kiro is not a vibe coder. Amazon also offers Quick, an AI assistant for business users, but Quick is more like Claude Cowork or CoPilot directory than a vibe-coding platform such as Lovable or Replit.
That gap makes the Superblocks partnership strategic. AWS gets a credible vibe-coding offering for its enterprise customers, while Superblocks gains distribution through one of the world's largest cloud providers.
An AWS spokesperson confirmed the company's interest in the category. "We support partners where we see strong customer demand and alignment with how customers want to build," the spokesperson said.
The spokesperson added, "It's an emerging category with real momentum, and exactly the kind of innovation we support."

The deal also reflects a broader shift in how enterprises are thinking about AI models. Microsoft CEO Satya Nadella has been telling enterprise customers to use multiple models to reduce costs and avoid lock-in. He has also warned that AI labs are not trustworthy enough for agent orchestration or app-level harnesses.
Menezes said the market has already moved in that direction. "That is flipped because 60 days ago they were like, I want a specific model. It's called Anthropic," he said.
He described the new reality for CIOs. "Having a multi-model strategy across big frontier labs, OpenAI, Anthropic, and open source, and I'd say Chinese open source right now, but also U.S. open source is now starting to come up. It's a must-have for the CIO," Menezes said.
He went further with a blunt prediction. "Any enterprise that is betting on a single model provider, that executive will be fired."
The numbers back up the trend. Open models accounted for 29% of all traffic routed through Vercel's AI gateway last month. Vercel is a popular tool for managing multi-model AI use, and its data suggests enterprises are already voting with their traffic.
A second wave for enterprise AI
The Superblocks-AWS agreement could represent a second wave after the initial push to bring AI coding agents to enterprise developers. The first wave focused on professional developers. This one targets business users who want to build apps without writing code.
Superblocks raised a total of $60 million as of its Series A, announced in May 2025. The round was backed by Spark Capital, Kleiner Perkins, Meritech Capital, and Greenoaks. The startup is early-stage, but the AWS deal gives it a distribution channel that most young companies can only dream of.
The agreement also signals that hyperscalers want enterprises to buy AI scaffolding from them, not from frontier model providers. Cloud providers are pushing the idea that enterprises should separate AI models from the harness, orchestration, and security tools that run on their clouds. Superblocks fits neatly into that pitch.
For AWS, the partnership is a way to capture more of the AI application layer. For Superblocks, it is a chance to scale quickly inside the enterprise market. For enterprises, it offers a vibe-coding option that keeps data inside their own cloud boundaries.
The deal does not mean AWS is abandoning its own AI efforts. Kiro and Quick remain separate products. But the partnership shows that AWS is willing to lean on partners where it lacks a native offering.
Menezes framed the deal as a natural fit for the moment. Enterprises want AI tools that work with their existing cloud infrastructure, respect their security requirements, and do not lock them into a single model provider. Superblocks, running inside AWS private clouds, checks all three boxes.
The result is a partnership that could accelerate vibe-coding adoption in the enterprise, while giving AWS a stronger story for customers that want AI without the risk.
