Sandstone's CentriFluidic technology is transforming healthcare by enabling centrifugation anywhere, anytime. Our handheld, battery-powered devices enable rapid separations and tests addressing a wide range of clinical areas including male fertility, infectious disease, and plasma stabilization. Sandstone’s lead product, the Trak® male fertility testing system, is an FDA-cleared home test kit that allows men to measure, track, and try to improve their sperm count at home (see trakfertility.com). Sandstone's Torq™ zero delay centrifuge system is a compact, portable, easy-to-use, and low-cost solution to immediately separate and stabilize plasma at the point of collection. Torq is a novel phlebotomy tool to dramatically reduce hemolysis and improve sample stability ahead of centralized lab testing.

INVESTING IN HIGH-PERFORMING, WOMEN-LED COMPANIES Currently investing from Astia Fund I - a $32M Series A/B fund that is sector and geography agnostic. For twenty years, Astia has carved a unique path to source, screen and invest in the top performing companies. Astia’s proprietary Expert Sift™ deal sourcing and screening process is a robust, data-driven methodology that uses best-in-class tools and wisdom-of-the-crowd techniques to eliminate bias. To successfully address the intersectionality of race and gender, Astia established a clear focus on investing in women of color. Grounded in deep domain expertise, exceptional investment performance, a belief in the value of women as leaders and a proprietary investment process, Astia invests via a family of funds. Throughout its twenty years, Astia has paved the way for investors to align human values with investment rigor. Understanding the fundamentals of change, Astia has built an institution to last. Through a variety of investment vehicles, Astia enables investment at all stages of private company growth. With an acute understanding of the unique challenges of high-growth, Astia ensures portfolio success. We are entrepreneur-centric and hands-on. By investing with Astia, Limited Partners expand their legacy of impact. Founded by tech pioneer Catherine Muther in 1998, Astia has never wavered from its fundamental commitment to level the investment playing field. Still today, less than 10 percent of VC investments are made into companies that include even one woman leader. We believe in investment as a force for change.
