Materials and chemicals companies are under pressure to improve their products year after year, but the technology supporting their R&D teams has not kept pace. Scientists are tasked with solving complex product development problems without the ability to harness the vast troves of data collected even within their own company.

Uncountable's mission is to accelerate R&D across the materials and chemicals industry. Our founding team of MIT and Stanford engineers brings expertise in software development and creating real-world artificial intelligence solutions. Headquartered in San Francisco, we are building a team of intellectually-curious, scientifically-inspired engineers and business leaders to deliver transformative solutions.
