AI Startup Code Audit

Building with LLMs? The Attack Surface Just Got a Lot Bigger.

Security and reliability code audits for AI-native startups — LLM wrappers, RAG applications, AI agents, multi-step workflows, and products built on OpenAI, Anthropic, or Gemini.

AI-native products have an entirely new class of vulnerabilities: prompt injection, data leakage across conversation contexts, unbounded token spend, and unsafe tool execution. On top of standard code quality issues, we audit the AI layer specifically — because your LLM is part of your attack surface.

What Goes Wrong

The AI Startups Code Bugs We Find Most Often

These are not hypothetical risks. These are the patterns we find in real ai & llm startups codebases built with AI coding tools — Cursor, Claude, Lovable, Bolt, Replit, and GitHub Copilot. Every item below is something we can find, report on, and help you fix.

Prompt Injection and Jailbreak Vectors

If your app takes user input and passes it into a prompt, it has a prompt injection surface. We test whether malicious users can override your system prompt, extract your instructions, make the model do things it shouldn't, or use your AI feature to attack other users.

Data Leakage Across User Contexts

RAG systems that pull from a shared knowledge base, conversation memory that persists incorrectly across sessions, and LLM context windows that accumulate prior user data are all paths to cross-user data leakage. We trace every data path in your AI layer.

Unbounded Token Spend and Cost Explosions

Without rate limiting, max token controls, and spend caps at the user level, a single malicious request can cost you thousands of dollars. We audit every LLM call for missing guards, and test whether adversarial inputs can force expensive completions.

Unsafe Agentic Tool Execution

AI agents with tool calling — file access, web browsing, code execution, API calls — need sandboxing and scope limits that AI-generated agent code almost never implements correctly. We test whether your agent can be coerced into taking destructive actions.

Vector Database and Retrieval Security

Retrieval-augmented generation systems store sensitive data in vector databases with embeddings. Access control, namespace isolation, and injection of malicious documents into the retrieval index are all risks we audit specifically.

LLM Output Trust and Hallucination Risk

If your app acts on LLM output — parsing structured data, executing suggestions, routing decisions — weak output validation is a reliability and security risk. We check every place your code trusts LLM output without sufficient validation.

Compliance & Regulatory Context

AI applications increasingly face regulatory scrutiny: EU AI Act risk classification, NIST AI RMF alignment, and sector-specific AI rules in finance and healthcare. We flag the code-level practices most likely to cause compliance problems as AI regulation matures.
