AI Development Companies

AI development companies build software that uses machine learning or large language models: chat assistants trained on your documents, document and image processing, recommendations, forecasting and automation of repetitive work. Many also add AI features to an existing web or mobile app through APIs from model providers.

Compare these companies on the problems they have solved, not on the models they mention. Ask how they measure whether a feature works, how they handle your data, and what the running cost per month will be once the feature is live.

What to check before you hire

• Past AI projects you can see or try, and what each one measured (accuracy, time saved, cost per request).
• Where your data is stored and sent, and whether it is used to train anyone else's model.
• Who owns the code, prompts, fine-tuned models and training data at the end of the project.
• Ongoing costs: model or API usage, hosting, monitoring and retraining.
• A small paid pilot before a full build, with a clear test set and pass mark.
