Clearly outline what you want the animation to achieve—brand awareness, education, or product promotion. Know your target audience and preferred video style (2D, 3D, explainer, etc.).
Determine how much you're willing to invest and your deadline. This helps narrow down agencies that align with your scope and expectations.
Look for agencies with strong portfolios, client testimonials, and relevant experience in your industry. Check their websites, social media, and platforms like Clutch or Behance.
