We are transforming the way therapeutics and materials are discovered. Our differentiated, physics-based software platform enables discovery of high-quality, novel molecules for drug development and materials applications more rapidly, at lower cost, and with, we believe, a higher likelihood of success compared to traditional methods. Our software is used by biopharmaceutical and industrial companies, academic institutions, and government laboratories around the world, and we are the leading provider of computational software solutions for drug discovery. We also apply our computational platform to a broad pipeline of drug discovery programs in collaboration with biopharmaceutical companies, some of which we co-founded. In addition, we are using our platform to advance a pipeline of internal, wholly-owned drug discovery programs. We offer our customers a variety of software solutions that accelerate all stages of molecule discovery, design, and optimization. In 2018, all of the top 20 pharmaceutical companies, measured by revenue, licensed our solutions, accounting for $22.0 million, or 33%, of our 2018 revenue. The widespread adoption of our software, supported by our global team of sales, technical, and scientific personnel, has driven steady growth in our software revenue. Biopharmaceutical companies are increasingly adopting our software at a larger scale, and we anticipate this scaling-up will drive future revenue growth.
