How to Choose an AI Development Company: The Vetting Playbook

Businesses are investing heavily in custom AI integrations. Partnering with a specialized development team helps organizations build search databases, automate workflows, and deploy autonomous agents.

However, the market is crowded with agencies claiming to be AI specialists who simply build simple wrapper apps using default settings. Hiring the wrong agency can result in wasted budget, project delays, and data security risks.

This vetting playbook provides key questions, technical tests, and contract terms to evaluate when choosing an AI development company.

1. Verify Their Database and Security Expertise

AI software is only as secure as the database it connects to. If a development agency does not have database architects on staff, your customer data will be vulnerable to prompt injections or cross-tenant leaks.

Ask the Technical Team:

• "How do you isolate client files inside RAG (Retrieval-Augmented Generation) databases?"
• Red Flag Answer: "We create separate folders in S3 or filter the output using GPT prompts."
• Correct Answer: "We use relational databases (like PostgreSQL) with pgvector and enforce strict Row-Level Security (RLS) policies. Every vector query is filtered using the authenticated user's tenant ID, ensuring absolute isolation at the database layer."
• "How do you protect API endpoints from prompt injection attacks?"
• Correct Answer: "We validate all inputs using schemas (like Zod) to block injection characters. We isolate system prompts from user messages and run outputs through verification parsers before execution."

2. Evaluate Code Quality & DevOps Standards

A professional development company does not build software on local laptops and manually upload it to servers. They use structured processes to ensure code quality and deployment safety.

Look for These DevOps Practices:

• Automated Testing (CI/CD): The team should use automated pipelines (like GitHub Actions) to run lint checks, typing tests, and security scans on every code change.
• Branching Strategy: They should use GitFlow (separating development, staging, and production branches) so new features can be fully tested in staging before going live.
• Clean Codebases: Ask for sample anonymized code or repos to verify they use TypeScript and write clear inline comments.

3. Review IP Ownership and Contract Terms

When hiring an external software team, you are building an intellectual property asset. Ensure your contract protects your ownership rights from Day 1.

Critical Contract Clauses:

• Full IP Ownership Transfer: The agreement must state that all code, designs, and data configurations built during the project are 100% owned by your company, with no ongoing licensing fees owed to the agency.
• No Vendor Lock-in: The software must be built using open-source frameworks (like Next.js, Node, and Postgres) rather than proprietary agency templates, allowing any developer to maintain the codebase in the future.
• Clear Milestones: Tie payments to specific deliverables (e.g., scoping document delivery, staging sandbox prototype, production rollout) rather than time-based invoices.

4. The Agency Evaluation Scorecard

Use this scoring rubric to compare agencies during sales conversations:

| Evaluation Area | Red Flag (0 points) | Industry Standard (1 point) | Enterprise Standard (2 points) | |---|---|---|---| | Data Isolation | Uses prompt tricks only | Uses vector collection folders | PostgreSQL RLS + strict DB-level filtering | | DevOps Pipelines | Manual server uploads | Basic CI/CD test runs | Full GitFlow, automated linting, and staging tests | | IP Policy | Demands ongoing licensing | Transfers IP upon final invoice | Transfers IP automatically as work is paid for | | Development Team | Uses general contractors | Standard full-stack developers | Led by security researchers with M.Tech degrees | | Model Hosting | Third-party cloud only | Standard Cloud API | Supports local cloud hosting and self-hosted LLMs |
