Qvin is the first and only healthcare service to scientifically prove menstrual blood can test for critical health information – just like a traditional laboratory blood test. Women's health has always been under-prioritized in science. We still operate in a world built by men, for men. It’s why in 2014, Dr. Sara Naseri and Søren Therkelsen started Qvin to research, develop, and patent a product that powers an underserved and understudied population—women. Over 70% of the decisions our doctors make are influenced by blood test results. Every month, 1.8 billion people across the world menstruate. However, the blood our bodies naturally deliver every month has never been explored as a testing source. And yet, menstrual blood has been left unexplored. Qvin is the first and only healthcare service to use period blood as a non-invasive blood test. We exist to give women an easy, insightful way to monitor existing health issues, proactively screen for others, and go into doctor visits more informed and confident of their own health. Our health technology platform helps women manage their health better through a non-invasive blood collection device named the Q-Pad™. All of us at Qvin want to move the study of women forward. We want to close the gender data gap. And we stand for every person who identifies with women, however they define it.

REGENT is building a new mode of transportation that will redefine regional mobility by 2026. Their first product, the seaglider, is an all-electric, hydrofoiling flying-boat that operates within a wingspan of the water's surface. By flying low on a cushion of air, seagliders unlock the ability to fly twice as far as an electric aircraft, while being regulated by maritime authorities enabling market entry for a fraction of the cost. REGENT has de-risked seaglider technology with a ¼-scale flying demonstration vehicle. By this summer, REGENT will fly humans on the 15,000 lb (7000kg) first full-scale prototype seaglider, which will be the largest electric-flying machine in history. By late 2026, REGENT’s customers - airlines and ferry companies – will begin commercial seaglider service on the 12-seat initial product. A 100 passenger version, already with firm orders, will follow several years later. In just four years, REGENT has accumulated >$10B in pre-orders (including firm deposits) from airlines and ferry companies around the world. Currently a team of 100, REGENT is led by MIT-trained, ex-Boeing engineers Billy Thalheimer and Mike Klinker. REGENT has raised over $100M to date from the likes of Founders Fund, Japan Airlines, Hawaiian Airlines and Lockheed Martin, and is on contract with the US Marine Corps.
