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 in 2025.
• Enterprise companies can now use Superblocks entirely inside their own private AWS cloud, so sensitive data never leaves their network.
• Superblocks has raised $60 million in total funding, backed by Spark Capital, Kleiner Perkins, and two other investors, Meritech Capital and Greenoaks.
• Open-source AI models accounted for 29% of all traffic through Vercel's AI gateway last month.
• Superblocks CEO Brad Menezes predicts any executive who bets on a single AI model provider will lose their job.

Imagine building a working business app simply by describing what you want in plain English, no coding required. That is vibe coding. Until recently, the apps it produced had a problem: they sent company data to external servers that IT teams had no control over.

Superblocks wants to fix that.

The San Francisco startup just struck a multi-year marketing agreement with Amazon Web Services, the cloud computing arm of Amazon. First reported by TechCrunch AI, the deal lets companies already running on AWS add Superblocks to their setup. Apps built with Superblocks 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 or a sales rep building an internal tool is no longer accidentally pushing sensitive records to a third-party server. Every app automatically falls under IT's existing rules.

Apps will connect to Amazon Aurora, Amazon's own database service, and Amazon Bedrock, Amazon's platform for building AI-powered software. We covered Bedrock on 3 August 2026 when it first appeared in our reporting. IT managers keep their audit trails. Security teams keep their controls.

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

Is this about one startup, or something bigger?

Something bigger. The deal reflects a broad shift playing out across the industry.

Cloud giants want enterprises to buy AI tools and security layers from the cloud itself, not from AI labs like OpenAI or Anthropic. Microsoft's CEO Satya Nadella has been making exactly that argument, 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 demanded one specific model, Anthropic's Claude. Now they want several at once, including Chinese open-source options. Open-source models made up 29% of all traffic through Vercel's AI gateway last month. That number carries more weight alongside the multi-model trend our July 28 story on Perplexity's Model Council first flagged for enterprise readers.

"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. The real story, though, is what it signals: vibe coding for business users is going corporate, and the cloud providers are making sure it happens on their turf rather than anyone else's. Watch whether Microsoft announces something similar before the end of the quarter.
