Once you have a trained team, it pays off because they know what to look for. Some objects just blend into the background in images, so you need a trained eye to spot them.

When our CEO Wendy Gonzalez took the stage at Super AI 2025, she delivered a stark message: The AI industry is facing a crisis that goes far beyond technical challenges. With 70% of AI deployments still failing and Gartner projecting $30 billion in spending to combat AI misinformation alone, the question is no longer whether we can afford to prioritize diversity in AI development. It has become a categorical imperative.
Sama provides ML Professionals and AI team Leads with an indispensable solution for Computer Vision data labeling.
