How to choose the right AI product agency

When evaluating AI product agencies, consider:

Technical AI expertise – Verify the agency's experience with relevant AI technologies (LLMs, RAG, computer vision, NLP) and their understanding of modern frameworks, model architectures, and deployment practices.

Production track record – Review case studies for AI systems that work reliably in production, not just demos or prototypes. Ask about system stability, latency, accuracy metrics, and how they handle edge cases.

AI UX capability – Assess the agency's understanding of designing for probabilistic systems including handling uncertainty, managing user expectations, and creating interfaces that leverage AI capabilities appropriately.

Full-stack capability – Determine whether you need AI-only development or integrated design, engineering, and product strategy. Some agencies specialise in AI implementation while others offer end-to-end product development.

MLOps and infrastructure – Confirm the agency's experience with model deployment, monitoring, and maintenance including cloud platforms, scaling, and continuous improvement of AI systems.

Ethical AI and safety – Evaluate the agency's approach to AI safety, bias mitigation, and responsible AI development, particularly for customer-facing applications or regulated industries.
