Nullify

Nullify is a provider of an AI-powered autonomous product security platform that continuously analyzes code, cloud, and APIs to identify vulnerabilities, validate exploitability, and create merge-ready fixes. The platform replaces disconnected scanners, triage queues, and remediation handoffs with one continuously managed workflow that includes code security (SAST), secrets detection, software composition analysis, cloud security, and AI pentest agents. Nullify differentiates itself through its Vault knowledge graph that ingests code, cloud, tickets, and documentation to build a unified ontology, enabling business logic flaw detection that pattern scanners cannot find, such as broken access control and IDOR. The platform features self-healing fixes that automatically refactor pull requests until CI passes, achieving an 89% merge-ready rate. Nullify routes fixes to the right codeowners based on ownership context and review capacity, manages campaigns through review with Slack escalations, and auto-suppresses 80% of low-severity noise. Founded in 2022 and headquartered in Sydney, Australia, Nullify has raised approximately 7 million at the Seed stage with investors including Two Sigma Ventures, Root Ventures, OIF Ventures, and SYN Ventures.
