Mighty AI

Mighty AI (originally Spare5) was a training data company that crowdsourced human-labeled data for training machine learning models. Founded by Matt Bencke and others, the company built a platform where human annotators would label images, videos, and text to create the training datasets that AI models need to learn. The company focused on high-quality, pixel-perfect annotations for autonomous vehicles — one of the most demanding use cases for training data. Mighty AI raised $27 million and built an impressive client list including leading autonomous vehicle companies. The platform employed thousands of crowdsourced annotators and developed sophisticated quality control systems. But the training data market quickly became brutally competitive. Companies like Scale AI, Labelbox, and offshore labeling operations in India and the Philippines offered similar services at dramatically lower prices. The market dynamics were terrible for a venture-backed company: customers treated training data as a commodity and switched providers based primarily on price. Mighty AI's premium quality positioning couldn't sustain pricing sufficient to cover its costs and deliver VC-level returns. In 2019, Uber acquired Mighty AI in what was widely reported as an acqui-hire — the team was absorbed into Uber's autonomous driving division (ATG), but the price was reportedly well below the $27 million invested. The acquisition was part of Uber's strategy to bring training data labeling in-house rather than relying on third-party providers. Mighty AI's story illustrates the dangerous economics of selling commoditized inputs to AI companies — even when those inputs are essential.
