By Eduard Kovacs | February 5, 2026 (8:02 AM ET) Flipboard Reddit Whatsapp Email Cybersecurity startup Nullify announced raising $12.5 million in seed funding to advance its AI workforce designed for vulnerability management. The investment round was led by SYN Ventures, with participation from existing backer Black Nova Venture Capital. This latest infusion brings the company’s total funding to $16.9 million, with the new capital earmarked for scaling go-to-market efforts, growing engineering and research teams, and driving international expansion. Nullify develops an AI-based system that functions as an autonomous workforce for handling product security tasks, focusing on detection, triage, validation, and remediation of vulnerabilities. The platform integrates with codebases, cloud environments, ticketing systems, and documentation to absorb contextual data through a component called Vault, which serves as a long-term memory for organizational security knowledge. By processing this information, Nullify’s AI generates exploit hypotheses, tests them in real scenarios, scores risks based on exploitability and impact, and produces patches. ADVERTISEMENT.

Headquartered in San Francisco, Nullify targets mid-market enterprises and SaaS companies seeking to streamline their security operations amid talent shortages.
