Prime Security Raises $20 Million Series A to Revolutionize AI-Driven Product Security

Prime Security, an AI‑driven cybersecurity startup focused on embedding product security early in the software development lifecycle, has raised $20 million in a Series A funding round to accelerate growth and expand its Agentic Product Security Platform. The financing follows an earlier $6 million seed round and underscores growing investor interest in solutions that bring automated, design‑stage security to modern engineering workflows.

The Series A round was led by Scale Venture Partners, a venture capital firm that backs software and cybersecurity innovators, with participation from Foundation Capital, Flybridge Ventures, and Ofir Ehrlich, CEO and Founder of Eon. This group of investors combines deep experience in early‑stage tech and enterprise security, reflecting confidence in Prime Security’s mission to transform how organizations manage risk in increasingly complex development environments.

Founded in 2023 and headquartered in New York with offices in Tel Aviv, Prime Security has built its reputation on advancing a new paradigm for product security — one where risk detection and mitigation begin at the design phase rather than waiting for traditional testing and code review stages. The company’s flagship product, the Agentic Security Architect, leverages autonomous AI agents to continuously monitor, assess, and guide security decisions throughout the software development lifecycle, enabling security teams to scale coverage across all planned work.

The principle behind Prime’s approach is that modern engineering teams operate at machine speed, often producing features and code much faster than manual security reviews can keep up. Traditional security processes are labor intensive and typically cover a small fraction of development work, leaving many design decisions unexamined until late in the process. Prime’s AI‑driven system intervenes early, scanning design intent before code is written and providing actionable recommendations that integrate directly into engineering workflows.

Prime Security’s technology has already gained traction with a range of enterprise clients. Organizations including PayPal, Qualtrics, Bumble, ThoughtSpot, and Redis Labs are using the platform to accelerate security reviews, with reported results showing up to 30 times faster resolution of design‑stage risks, 100 percent coverage of planned work, and up to 50 percent reductions in time and cost spent on security assessments compared with manual methods. These early customer wins demonstrate the practical impact of shifting security left in the development process.

Prime’s founders — including Michael Nov, Co‑Founder and CEO — bring deep experience from leading roles in software, security, and enterprise product teams. Their vision is centered on making security a seamless, embedded part of engineering rather than a separate step that slows development. With the newly raised capital, the company plans to further develop its AI capabilities and expand its go‑to‑market initiatives to reach a broader set of customers across industries.

The investment will support not only technology advancement but also scaling operational functions, including expanding sales, marketing, and customer success teams to drive broader adoption. Prime intends to invest in enhanced integrations with engineering and development tools, enabling security professionals to gain real‑time insights into risks before they materialize into vulnerabilities.

Prime Security’s evolution from a seed‑funded stealth company to a Series A‑backed innovator reflects broader trends in cybersecurity funding, where investors are increasingly allocating capital to startups that offer AI‑enabled automation and early detection capabilities. As development environments grow more complex and distributed, tools that can proactively identify risks and streamline security processes are becoming essential for organizations seeking to protect their software supply chain.

The participation of investors like Scale Venture Partners, Foundation Capital, and Flybridge Ventures — all with strong track records in enterprise software and security — signals belief in Prime’s ability to lead a new category of product security tooling. With its Agentic Security Architect platform and growing customer base, Prime is positioned to help companies reimagine how security integrates into rapid software delivery cycles.

As demand for AI‑driven cybersecurity solutions continues to rise, Prime Security’s successful Series A funding round highlights the importance of innovation in design‑stage security and the broader shift toward predictive, automated risk management in software engineering.
