How to choose the right AI development company for your next AI project?
When selecting a company to develop custom AI software for your organisation, consider these key factors:
Where to outsource?
- IT outsourcing types: Take some time to research the differences between common IT outsourcing types and team engagement models
- Nearshore or offshore: Compare nearshoring and offshoring with all their pros and cons and see which will best fit your company
Proper experience and expertise
- AI specialisation: Look for companies with specific expertise in the type of AI solution you need (machine learning, computer vision, generative AI, NLP, etc.)
- Portfolio and case studies: Review their previous AI projects, especially those similar to your requirements
- Technical team: Evaluate the qualifications of their data scientists, ML engineers, and developers
Development approach
- Understanding of your domain: For companies who don't have hands-on experience within your specific domain, it can take time to thoroughly understand your industry, its unique challenges, and objectives. That's why it's wise to look for domain experienced companies knowledgeable about industry-specific processes and technologies
- Data strategy: Assess their how they plan to handle data collection, preparation, and management
- Model development process: Look for transparent methodologies and iterative approaches like agile

Practical considerations

- Intellectual property rights: Establish who owns the developed technology and algorithms
- Communication style: Choose a technological partner who excels at clear, frequent and transparent communication. Look at testimonials from previous clients (you can even arrange a call with some of them). But most importantly, book a get-to-know call to get a first-hand impression of their communication but also how they're able to help with your next AI project.
