Founding Story

The founders—Manu Sharma, Brian Rieger, and Dan Rasmuson—identified a critical bottleneck in AI development while working in aerospace engineering. They recognized that deep learning was becoming a major force in technology, particularly in self-driving cars, but would eventually power many other facets of life. They realized that the only way to create these AI models was through human-labeled data, which presented significant challenges in terms of difficulty, delays, and false starts. The founders initially built Labelbox on nights and weekends as their third business together, launching it on Reddit to gain early traction. The company emerged from six months in stealth mode in July 2018 with $3.9 million in seed funding.
