AWS Signs On With Vibe-Coding Startup Superblocks, and the Message to Big Tech Is Clear

Key points

• Superblocks, a 50-person startup, announced a multi-year marketing partnership with Amazon Web Services (AWS) in 2025.
• Under the deal, enterprise companies can use Superblocks to build apps entirely inside their own private AWS cloud, so data never leaves their network.
• Superblocks raised $60 million in total funding as of its Series A in May 2025, backed by Spark Capital, Kleiner Perkins, Meritech Capital, and Greenoaks.
• Open-source AI models, meaning AI built by anyone and shared freely, accounted for 29% of all AI traffic through Vercel's management platform last month.
• Superblocks CEO Brad Menezes predicts any executive who bets on a single AI model provider will lose their job.

Imagine you could build a working business app simply by describing what you want in plain English, no coding required. That is vibe coding. And until recently, the apps it produced had a problem: they sent your company's data out to external servers that your IT team had no control over.

Superblocks wants to fix that.

The San Francisco startup, first reported by TechCrunch AI, just struck a multi-year marketing agreement with Amazon Web Services, the cloud computing arm of Amazon and one of the biggest technology suppliers on the planet. The deal lets companies that already run their digital operations on AWS add Superblocks to that setup. Apps built with Superblocks will now spin up entirely inside a company's own private cloud, the secure, fenced-off corner of AWS that belongs exclusively to that business.

"Data never leaves," Superblocks co-founder and CEO Brad Menezes told TechCrunch. "It's their AWS account, basically secure with all of the auditing, all of the encryption, all of the network controls."

Why does it matter that data stays inside the company?

It means a nurse, a shop manager or a sales rep building an internal tool with Superblocks is no longer accidentally pushing sensitive company records to a third-party server. Every app automatically falls under IT's existing rules.

The apps will connect to Amazon Aurora, Amazon's own database service, and Amazon Bedrock, Amazon's platform for building AI-powered software. IT managers keep their audit trails. Security teams keep their controls. Nobody gets a call from compliance.

AWS will also help sell Superblocks directly to its business customers, the kind of quiet distribution boost that can make or break an early-stage startup.

Is this about one startup, or something bigger?

Honestly? Something bigger. The deal reflects a broad shift playing out across the industry right now.

Cloud giants like AWS and Microsoft want enterprises to buy their AI tools, their security layers, and their app-building platforms from the cloud itself, not from the AI labs like OpenAI or Anthropic. Microsoft's CEO Satya Nadella has been making exactly that argument publicly, warning enterprise customers that AI labs could study the data companies share with them and eventually compete against those same businesses.

Enterprises are already voting with their feet. Menezes says that 60 days ago clients were demanding one specific model: Anthropic's Claude. Now they want several models at once, including Chinese open-source options. Open-source AI models made up 29% of all traffic through Vercel's AI management platform last month, a striking jump.

"Having a multi-model strategy across big frontier labs, OpenAI, Anthropic, and open source: it's a must-have for the CIO," Menezes said.

His bluntest prediction: "Any enterprise that is betting on a single model provider, that executive will be fired."

For Superblocks, a 50-person company with $60 million raised, landing AWS as a marketing partner is a serious leg up. For the rest of the industry, it signals that vibe coding for business users is about to get a lot more corporate, and a lot more controlled.
