Questor Inc.

Enterprise Code Intelligence & Security Platform

Our Purpose

Code Intelligence Pipeline Source Code AST Parsing Function Extraction Embedding Generation Analysis Layers • Vulnerability Detection • License Compliance • Code Provenance • Similarity Matching Intelligence Database Indexed & searchable Query

Questor empowers organizations to understand, secure and optimize their software assets through AI-powered code intelligence. We transform how enterprises manage code quality, security vulnerabilities, OSS license compliance and code provenance at scale.

In an era where software complexity grows exponentially with AI generated code, software composition and supply chain security is paramount, organizations need comprehensive visibility into their code. Questor provides production-scale semantic analysis, vulnerability detection and code attribution—enabling engineering teams to make informed decisions about code reuse, security risks and licensing obligations.

Our platform analyzes millions of functions across thousands of repositories, delivering actionable intelligence that helps organizations ship secure, compliant and high-quality software faster.

If code has been copied from Github, our platform will tell you exactly where that code came from (even if it's been modified), what OSS licenses are associated, what the known CVEs are and it will do it in near real time.

What We Do

đź§  Semantic Code Analysis

Deep understanding of code through AI-powered embeddings. Find similar functions, detect duplicates and understand code relationships.

🛡️ Vulnerability Intelligence

Multi-source CVE correlation with automated pattern generation. Identify security risks before they become incidents.

🎯 Code Provenance

Advanced temporal analysis and source attribution. Know where code came from and trace its evolution through time.

📊 License Compliance

SPDX-compliant detection with comprehensive risk assessment. Identify GPL, AGPL and other copyleft licenses automatically.

🔄 Supply Chain Security

Dependency vulnerability tracking with contextual impact scoring. Understand your software supply chain risks.

Leadership

Questor was co-founded to address a critical gap in enterprise software development: the lack of comprehensive, scalable tools for understanding code quality, security and compliance at organizational scale.
