About us
PolyModels Hub kicked off in late 2022 with a mission: make modeling in Life Sciences easier for everyone and boost innovation. We started right here on Linkedin, building a community by sharing the latest research and open-source tools for life sciences. We are strong advocates for open-source modeling – it's akin to the transformation we saw in Software Dev and AI. That's why we recently introduced our open-source Hub, where you can sign up to discover, build and connect with the open-source community! Fast forward to 2024, and we decided to level up. We expanded PolyModels Hub to offer modeling services and products to the pharmaceutical industry. Our focus is on helping companies speed up their innovation in developing new drugs. We use the best digital design tools available, both open-source and proprietary, through our digital design approach and platform. The goal? Empower companies to launch medicines faster, save costs, and improve the quality of their products. And trust us, there's a lot more to come in our story!
