Superblocks, a leader in secure enterprise app development, announced it has raised $23 million as part of its Series A. This funding brings the total funding to $60 million. The 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.
The pitch: AI made it easier for non-technical employees to build software that streamlines their day-to-day work. However, it has 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 a large percentage of AI-generated solutions are either incorrect or contain security vulnerabilities, raising concerns about their safe adoption. Without enterprise-grade AI guardrails, the rise of AI app generation could pose the largest security threat to enterprises in decades.
New AI agent Clark: 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, guardrailled environment.
Clark enables 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.
Clark is now in early access as Superblocks ramps up capacity.
How the funding will be used: This funding helps Superblocks address the growing security risks of AI app generation in the era of vibe coding.
KEY QUOTES:
“We’re leaning into AI at Instacart to help transform the way we work. 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.”
Max Mullen, Co-founder of Instacart
“AI app generation has caught fire recently in a trend many are calling ‘vibe coding,’ 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.”
Brad Menezes, CEO and co-founder of Superblocks
“The rise of AI app generation is reshaping how companies operate internally. Superblocks is uniquely positioned to help enterprises harness this shift, giving companies the speed of AI without compromising on security or control.”
Yasmin Razavi, General Partner at Spark Capital
“Superblocks is taking a bold, inventive approach to one of the most expensive inefficiencies in business. 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.”
Mamoon Hamid, partner at Kleiner Perkins
