Amazon Web Services is teaming up with a startup called Superblocks. Superblocks makes tools that let business workers build software using AI, a practice known as vibe coding. The two companies signed a multiyear joint marketing agreement.
The deal lets Superblocks run inside the private clouds of AWS customers. This means a company's employees can build apps with AI help without sending company data outside their own cloud account.
How the Partnership Works
Apps built through Superblocks will use Amazon Aurora, a database service, instead of outside options like Supabase. Supabase is currently a common choice among many vibe-coding tools.
The apps will also connect to Amazon Bedrock. Bedrock is Amazon's platform for building and running AI applications.
Superblocks co-founder and CEO Brad Menezes said the goal is to keep company data inside the customer's own AWS account. He said this includes the auditing, encryption, and network controls that come with that account.
AWS will help sell Superblocks to its enterprise customers. This is a common practice for partners listed in the AWS Marketplace.
AWS does not have its own vibe-coding tool built for business users yet. It has a separate tool called Kiro, which is aimed at software developers rather than general employees.
Superblocks is a small company. It has 50 employees and has raised $60 million in total funding, including a Series A round announced in May 2025.
Investors in Superblocks include Spark Capital, Kleiner Perkins, Meritech Capital, and Greenoaks.
A Shift Toward Multiple AI Models
The partnership fits into a larger pattern happening across the cloud industry. Big cloud providers are encouraging their enterprise customers to separate their AI models from the other tools needed to run AI applications.
Cloud companies want businesses to buy security tools, orchestration software, and app-building tools from them. They do not want businesses relying only on AI companies for those same services.
Microsoft CEO Satya Nadella has been making a similar point in recent weeks. He has told customers to use multiple AI models to lower costs and avoid depending on just one provider.
Nadella has also said AI labs may not be trustworthy partners for tasks like agent orchestration. His concern is that these companies could use customer data to study a business and later compete with it.
Menezes said many enterprises have already moved toward using several AI models rather than just one. He said this shift includes growing use of Chinese open-weight models.
Open models made up 29% of all traffic passing through Vercel's AI gateway last month. That tool is widely used by companies managing AI traffic across multiple models.
Menezes said the shift has moved fast. He said interest in relying on a single AI provider has dropped sharply over the past two months.
He predicted that any company relying on just one AI model provider will eventually face problems. He said executives making that choice could lose their jobs over it.
The AWS and Superblocks partnership marks a step toward bringing AI app-building tools for business users into secure, private cloud environments. AWS described vibe coding as an emerging category with real momentum.
