With $60M in total funding, Superblocks brings AI app generation into the enterprise — empowering teams to build internal apps securely and under IT’s control

NEW YORK–(BUSINESS WIRE)–Superblocks, the leader in secure enterprise app development, today announced it has raised $23 million as part of its Series A, bringing its total funding to $60 million. The funding will help Superblocks address the growing security risks of AI app generation in the era of vibe coding. Investors in the round include Kleiner Perkins, Spark Capital, Greenoaks, Meritech Capital, and tech leaders like Box CEO Aaron Levie and Workday Founder Aneel Bhusri.

AI has made it easier than ever for non-technical employees to build software that streamlines their day-to-day work — but it’s also opened the door to new risks. When these tools are developed outside of IT’s oversight, they can lead to security breaches, compliance issues, and long-term maintenance chaos. A recent benchmark found that 62% of AI-generated solutions are either incorrect or contain a security vulnerability, raising alarms about safe adoption. Without enterprise-grade AI guardrails, the rise of AI app generation could become the largest threat to security facing enterprises in decades.

Superblocks’ new AI agent, Clark, solves this by giving both technical and non-technical teams the ability to build internal applications using natural language — all within a secure, guardrailed environment.

“We’re leaning into AI at Instacart to help transform the way we work,” said Max Mullen, Co-founder of Instacart. “Superblocks empowers our teams to rapidly build critical AI-driven applications, all while ensuring our data and access policies are securely enforced on a governed platform.”

Clark allows teams to build internal applications through a simple, chat-based development interface. When a user prompts Clark, the request is routed to a network of specialized AI agents that plan, design, secure, and test the application — all while enforcing the organization’s unique security policies, data permissions standards, and design rules. Clark also generates clean, traceable React code under the hood — giving engineering and IT teams full visibility, control, and auditability over each application developed.

“AI app generation has caught fire recently in a trend many are calling ‘vibe coding,’” said Brad Menezes, CEO and co-founder of Superblocks. “But this trend is moving faster than IT is able to govern it — introducing new attack surfaces as a result. What started as well-intentioned employees just trying to make the business more efficient will begin causing major security breaches in the very near future. Clark was designed for this moment — giving internal teams the speed and access of consumer vibe-coding tools, but with the guardrails, governance, and security enforcement enterprises require.”

“The rise of AI app generation is reshaping how companies operate internally,” said Yasmin Razavi, General Partner at Spark Capital. “Superblocks is uniquely positioned to help enterprises harness this shift, giving companies the speed of AI without compromising on security or control.”

“Superblocks is taking a bold, inventive approach to one of the most expensive inefficiencies in business,” said Mamoon Hamid, partner at Kleiner Perkins. “Instead of focusing on making engineers more efficient, they’ve empowered more teams to build the internal applications needed for back office workflows and operations.”

Clark is currently in early access as Superblocks ramps up capacity. To start using Clark, join the waitlist or get in touch at clark-ai@superblockshq.com.
