The XB100 is the definitive ranking of the world’s top private deep technology companies. XPRIZE Foundation and Bessemer Venture Partners have set out to define and study this promising cohort of businesses shaping the future. 

The XB100 is delineated into 9 categories: Agriculture, Artificial intelligence (AI), Aviation, Climate, Mobility, Next-gen biotech, Quantum, Robotics, and Space. We evaluated these businesses based on the following four criteria.


Impact on humanity

Seven judges evaluated each category’s impact on humanity: Anousheh Ansari, Emily Calandrelli, Lori Garver, Ray Johnson, Stacy Kauk, Ray Kurzweil, and Tina Seelig.



We obtained the last known valuation of the company based on third-party data providers, industry valuation methods, and additional factors.


Scientific difficulty

To assess the difficulty of a company’s scientific research, we relied on two proxies: (a) the number of PhDs at the company based on third-party data providers, and (b) the number of patents granted to the company according to geographical patent databases.


Commercial traction

We scored commercial traction using the Technology Readiness Level framework standardized by NASA. In the case of biotech companies, we examined whether a company is going through clinical trials.
