Whether placing a screw in the spine, inserting a needle for a biopsy, or advancing a catheter, precision is critical. Yet surgeons still rely on outdated tools: fluoroscopy, “feel”, and mental reconstruction, leading to inefficiencies, complications, and billions in unnecessary healthcare costs.\n\nThis has serious consequences:\n\n* For patients – misplaced implants, vascular injuries, and nerve damage result in repeat procedures, extended hospital stays, and life-altering complications.\n* For hospitals – preventable surgical revisions cost tens of billions annually in unnecessary expenses\n* For surgeons – Cumbersome tools and methods that extend case time, increase cognitive load, and limit the number of patients they can treat.\n\nSpine surgery and interventional access are two of the fastest-growing segments and also among the most accuracy-dependent.\n\nIn the US alone:\n\n* 1.6 M spine surgeries where millimeters can mean the difference between mobility and disability.\n* 9.5 M interventional procedures that rely on accurate percutaneous access to treat and diagnose hundreds of different conditions and diseases.\n\n**This is a $10B+ unmet need.**\n\n**🔎 Our Solution: See Inside The Patient in Real Time, Directly On The Body**\n\nWe’ve built a new way of seeing inside the human body: Skylight is the first real-time anatomical projection system built to solve the problems with patient access. Instead of forcing doctors to look away at a screen, Skylight projects anatomy directly onto the patient, like an AR display—but without headsets, wearables, or extra steps.\n\n![uploaded image](/media/?type=post&id=65365&key=user_uploads/636938/8f98ebe8-aa8b-44e5-aac5-1b03d5105bfd)\n\nTo make this happen, we’ve developed a novel method of tracking the patient with sub-millimeter accuracy and we’ve built this system to be universally compatible with industry-standard tools and scanners to allow adoption without changing workflow.\n\n![uploaded image](/media/?type=post&id=65365&key=user_uploads/636938/d4213fc6-0747-4211-8bc3-56a309fd14c9)\n\n**Just as fiber optics revolutionized how we do laparoscopy and minimally invasive surgeries, anatomical projection will become the new standard for patient access.**\n\n**Who We Are:**\n\nWe’re James and Eldrick, two Stanford engineers who first met as freshman dormmates and have now worked together for over a decade.\n\n💉James: MD, bioengineer, scientist, and medical device builder.\n\n⚙️ Eldrick: Experienced deep-tech founder. Built chips at Apple and led hardware-software teams at a lidar startup.\n\nWe’ve assembled a world-class team of engineers, clinicians, and medical device experts to solve tough problems at the intersection of medicine, computer vision, graphics, and hardware development.\n\n![uploaded image](/media/?type=post&id=65365&key=user_uploads/636938/f5a0197a-718d-45cf-b2bd-f71769312830)\n\n**We’re looking for:**\n\n🩺 Clinicians → If you do spine, pain management, or IR, let’s talk.\n\n🏥 Hospital Partners → Want to be at the forefront of procedural navigation?
