Superblocks, a company focused on enterprise-grade app development, has raised $23 million in Series A funding to support the rollout of Clark, its new AI-powered development assistant. The round brings Superblocks’ total funding to $60 million and reflects growing enterprise demand for secure AI tools that support software generation at scale.
The funding round includes investors such as Kleiner Perkins, Spark Capital, Greenoaks, Meritech Capital, and tech executives from Box and Workday. With AI rapidly changing how internal apps are built, Superblocks is positioning Clark as a governance-first platform for teams that want the benefits of AI-driven development—without the risks tied to unvetted tools or shadow IT.
Clark allows users to create internal business applications using natural language. Requests are interpreted by a network of specialized AI agents that design, plan, secure, and test applications based on organizational standards. Every app is backed by clean React code, providing traceability and giving IT teams full control.
Guardrails for the Vibe Coding Era
The rise of “vibe coding”—a trend where business users use generative AI to build tools with minimal oversight—has prompted new concerns about enterprise security. According to recent benchmarks, over 60% of AI-generated code solutions are flawed or insecure. Without proper controls, the same tools that promise to accelerate productivity can expose organizations to data breaches and long-term technical debt.
Superblocks addresses these issues by embedding enterprise governance, auditability, and security policy enforcement directly into the development process. IT teams maintain oversight without blocking innovation.
“Clark was designed for this moment,” said Brad Menezes, CEO and co-founder of Superblocks. “It brings the accessibility of consumer AI tools into a secure platform where IT can enforce compliance and code quality.” It’s worth noting Clark has a background in tech as well as investing – as a Sequoia Scout in fact, where Jason Calacanis of All In fame got a career jumpstart. Also – he built a YC-backed startup. Similar to Sam Altman – we went from tech company to investor and back to a tech company. One imagines – he saw this as a big opportunity – which makes sense – as to why he would leave Sequoia.
Shifting the Model of Internal Software Development
Superblocks takes a broader view of AI’s role in the enterprise—not as a tool for developers alone, but as a way to enable more teams to build business-critical applications. Max Mullen, co-founder of Instacart, credited the platform with enabling faster application delivery without compromising data access standards.
Backing from enterprise investors reflects that potential. “Superblocks is reshaping how companies operate internally,” said Yasmin Razavi, General Partner at Spark Capital. “It gives organizations the speed of AI without giving up control.”
