How Sama can build into and support your AI workflows
Initial project timelines, scope, and pricing
Sama works side by side with customer teams to deliver high-quality data that improves model performance.
Annotated product images and attributes across 2.5M+ SKUs to boost search and recommendation model accuracy and reduce false negatives in production.
Annotated millions of waste objects using instance segmentation and classification to improve PolyPerception’s visibility models at scale.
Inspired by Leila Janah’s belief that talent is equally distributed but opportunity is not, Sama creates full-time, fair-wage work for people historically excluded from the digital economy. We put people at the center of our data work because it leads to greater care, consistency, and trust.
As a Certified B Corporation (B Corp), Sama has supported more than 69,000 lives and built careers for over 15,000 associates while delivering data teams rely on to build technology that works in the real world. Data certainty starts here.
Scale your data process with a team of expert human-in-the-loop annotators – get models live on time and in budget.
