Data labeling and model evaluation for AI training

Technology, Information and Internet San Francisco, CA 11–50 employees Founded 2024 Privately Held

Perle is a data-curation and AI-evaluation platform founded by veterans from Scale, Amazon, Meta, and MIT. The hiring mix is heavily weighted toward data roles (58 active openings across annotation, curation, and quality assurance), with smaller engineering and research teams—a structure that reflects the labor-intensive nature of preparing training datasets at scale. Active projects span linguistic annotation, scientific reasoning evaluation, and adversarial feedback loops, pointing toward a platform designed for complex, human-guided model refinement rather than automated labeling alone.
