Nullify, an AI-driven product security RegTech company building what it describes as the world’s first autonomous AI workforce for security teams, has closed its seed funding round as it looks to scale growth across global software businesses.
The company has raised $12.5m in the round, which was led by SYN Ventures, with participation from existing investor Black Nova Venture Capital. As part of the investment, SYN Ventures operating partner Glenn Chisholm has joined Nullify’s board of directors. The latest raise brings Nullify’s total capital raised to $16.9m.
Founded to address what it sees as a widening gap between modern attack methods and overstretched security teams, Nullify provides an autonomous AI workforce designed to handle product security operations end-to-end. Rather than operating as a traditional security platform, the company positions its technology as a team of AI employees that independently manage vulnerability detection, triage, validation and remediation.
Nullify’s system ingests code, cloud configurations and business context to autonomously generate and validate exploits, assess real-world business impact and deliver merge-ready fixes. By doing so, it aims to eliminate the manual triage, tool sprawl and coordination challenges that dominate many legacy product security programmes. According to the company, customers using its AI workforce have replaced fragmented tools with a single autonomous layer that continuously learns and adapts to emerging threats.
The company says early adopters across dozens of organisations have already saved more than 48,000 hours of manual security work, auto-resolved over 450 vulnerabilities and achieved an average merge-ready rate of nearly 90% for vulnerability fix pull requests. The funding comes at a time when enterprises are facing increasingly sophisticated AI-enabled attackers alongside a persistent shortage of experienced security professionals.
The new capital will be used to scale Nullify’s go-to-market operations, expand its engineering and research teams, and accelerate global growth. The company’s focus is on bringing its AI workforce model to mid-sized enterprises and high-growth SaaS firms that are most constrained by limited security headcount and complex legacy tooling.
SYN Ventures operating partner and Nullify board director Glenn Chisholm said, “The security labor gap is the defining challenge for defenders today. Nullify’s first-of-its-kind AI workforce doesn’t just summarize alerts. It autonomously makes decisions and takes action, delivering outcomes that once required entire teams.”
He added, “I’m thrilled to join Nullify’s board as we partner to transform how enterprises defend against relentless, AI-driven threats.”
Nullify CEO and co-founder Shan Kulkarni said, “For organizations facing significantly greater speed and sophistication of AI-enabled attackers, holding the line with legacy dashboards, scanners, and ticket routing is a losing game.”
He added, “Whether organizations have a mature program or zero product security headcount, Nullify AI employees replace tool sprawl and the human hours it consumes, so defenders can finally outpace the offense. With SYN Ventures leading our latest funding, we now have the capital and the operating partnership to scale this model to the teams most constrained by talent shortages and legacy tool complexity.”
