AI TRAINING BOOM LIFTS HANDSHAKE REVENUE NEARLY 1B

The explosive growth underscores AI firms' insatiable need for quality training data. Handshake now contracts with lawyers, PhD holders, medical doctors and other specialists to evaluate AI-generated answers—work essential for improving large language models and other AI systems. The startup, which originally served as a job site for college graduates, entered AI training just over a year ago when revenue stood at $5-10 million annually. The 80-fold increase reflects AI's rapid scaling demands and the shortage of available talent for this labor-intensive work. Handshake is not alone. Mercor, another contractor platform, is similarly capitalizing on the trend. These startups fill a critical gap between AI developers needing human feedback loops and specialized professionals seeking flexible contract work. The model reveals a hidden layer of AI infrastructure: while headline companies build models, less visible firms quietly scale the human workforce powering their development. As AI competition intensifies, demand for quality training data shows no signs of cooling.
