Lunar is a stealth hospital technology company building a new type of software platform for hospitals. Built on a foundation of two years of research and development, the Lunar cloud platform brings state-of-the-art technology to solve some of the most frustrating challenges faced by hospitals today. The company focuses on using smarter automation, better data, and sensible machine learning to empower hospitals with the tools to provide more precise and effective care, doing things they can't today. This next-generation platform is a fundamental rebuild of the information infrastructure that runs health systems. All of it – from doctors, nurses, pharmacists, lab technicians, coders, billers, supply chain, and even patients – Lunar’s software powers everything, soup-to-nuts. We believe that this mission is the moon landing of healthcare – something so consequential and ambitious that most people believe it to be impossible. Backed by Silicon Valley’s preeminent venture capital firms, we believe in the power of a small, high performance team of seasoned professionals operating at the peak of their abilities. We value people who are driven, curious, have sound judgement, and care about doing the best work of their careers.

At Maihem, our mission is to empower every manufacturer, no matter their scale, to invent and build anything using intelligent robots. We are witnessing the start of a new industrial revolution—an era of rapid innovation and advanced manufacturing powered by AI and robotics. We aim to lead this shift by putting these tools into the hands of every manufacturer, ensuring the power to invent and build at scale isn’t a privilege of the few. But this era of abundance depends on solving a systemic labor crisis. For any economy to advance its industry and secure its supply chains, it must address the work that no longer attracts a human workforce. We are building AI to handle the dull, dirty, and dangerous. By offloading the hazardous and the mundane to intelligent machines, we empower manufacturers to compete globally while driving prosperity locally. In doing so, we enable the creation of new, purposeful jobs—ensuring that the future of innovation remains human-centric, boundless, and accessible to all.
