Automated security remediation that finds, proves, fixes and verifies vulnerabilities
QuestorAI is a Seattle-based application security company building technology to automatically identify and fix software vulnerabilities. Its platform combines deterministic code analysis with targeted use of foundation or locally deployed large language models to determine whether vulnerabilities are actually exploitable, give engineers the context behind each issue, and generate and validate fixes that preserve the software's intended behavior, with fixes increasingly applied autonomously as teams build confidence. In October 2026 it announced a $3 million seed round led by Paladin Capital Group with participation from Denver Ventures, to accelerate development, expand work with enterprise design partners and grow the team.
