How to Choose the Right AI Partner
Start by defining your project scope and budget. Do you need a full-service enterprise partner or a nimble freelance agency? Consider the level of collaboration you want—some agencies work closely with your team, while others take a more hands-off approach. Look for proven experience in your industry and ask for case studies. Pricing models vary widely, so clarify whether you are paying for time, deliverables, or a retainer. Finally, trust your gut: the best partnerships are built on transparency and shared vision.
